Indian Energy Scenario
Energy demand in India has been growing over the years and country is now placed fourth in terms of primary
energy consumption. On comparing this with world average of 1797 kilograms of oil equivalent (kgoe), India's
per capita consumption of 585 kilograms of oil equivalent (kgoe) is very low.
But, as per Planning Commission estimates consumption would rise to to 738.07 mtoe by 2016-171
and with
supply side bottlenecks there will be about 38 percent import reliance.

Table-1: Primary Energy Consumption of Top Five
Countries (2009)2
Table-2: Per Capita Energy Consumption (2009)3
Energy consumption in India is highly dependent on hydrocarbon fuels with only 10% made up by cleaner and
renewable sources.
Figure-1: Indian Energy Mix 4
Now, with huge growth in projected demands and impending import dependence, it seems reasonable that
emphasis needs to be given on sustainable abundant sources of energy.
Energy Security
Over the years challenges have emerged with lack in domestic coal production mainly attributed to
infrastructure constraints, also there are concerns of environmental in case of large hydro plants, thermal power
plant emissions and then heightened nuclear risk after Fukushima disaster. With existing supply-demand
imbalance in range of 12.7% peak deficits, situation is likely to worsen in near future. Add to it, 50% of
population has little or no access to commercial and majority others face erratic supplies.
To address all these requirements it is necessary to arrive at a prudent energy mix by harnessing renewable
sources which are resourceful domestically. However, high costs of energy generation associated with
renewable sources are a major restraint but supportive government policies will allow it to compete
economically with fossil fuels over time.
Integrated Energy Policy, 2006 was the first formal step by Indian govt. to rationalize domestic energy mix.
This was followed by institution of a full-fledged Ministry on New and Renewable Energy (MNRE) which is a
nodal agency to facilitate implementation of all programmes on renewable energy resources.
Renewable energy sources in India
Renewable energy can be derived from natural sources like water, sun, wind, geothermal, tidal, biofuels etc.
Being inexhaustible and replenish able source, they are clean and have no harmful effects on natural ecosystem.
As per govt. data, wind energy is the largest harnessed renewable source in India. But, supporting policies are
increasing contribution from Solar for past few years.
Figure-2: Contribution of various RES (on-grid) Source: www.mnre.gov.in (as on 30/9/2013)
Solar Energy
Annually about 5,000 trillion kWh5
of solar energy is incident on India with average insolation of about 4-7
kWh per sq. m per day over most of the land area. This makes it technologically feasible to convert this huge
reservoir of energy efficiently into heat and electricity by using solar PV and solar thermal systems. Also,
geographical location of India is such that major land mass receives the average insolation for 5 hours daily and
this presents a case for easy scalability.
National Solar Mission6
Given the context, government embarked on the ambitious goal by launching Jawaharlal Nehru National Solar
Mission. The objective was to develop solar energy as a competitive alternative for hydrocarbons based energy
sources. Additional advantage was that change in energy mix, will make development more inclusive as off-
grid systems will empower marginalized and deprived people.
The mission also earmarked goals for promoting R&D program in collaboration with leading researchers in the
field. Mission targets are:
68%
13%
4%
8%
7% 0.34%

Table-3: JNNSM Capacity Addition Target7
Domestic manufacturing
India’s Solar PV industry is dependent on imported components, major one being the silicon wafers. And to
promote domestic manufacturing, the mission set a target of 4-5 GW equivalent manufacturing capacity by
2020. By March 2013, the total capacity has touched 2000 MW as per MNRE announcement.8
The break-up of different components are,
Table-4: Manufacturing Facility9
However, India doesn’t have any poly-silicon production capacity and no capability in solar thermal projects;
but with new policies and sector will get boost to develop these alternate technologies.
Solar cell Technology: Future Outlook
Currently crystalline silicon is the most common technology, and its manufacturing processes are similar to that
of electronic circuitry industry. But, gradual advancements and better efficiencies are making the “thin-film”
cells as preferred choices.
c-Si : Crystalline Silicon
a-Si : Amorphous Silicon
CIS : Copper Indium Selenide
CIGS : Copper Indium Gallium Selenide
CdTe : Cadmium Telluride
Figure-4: Solar PV Module Technology10
However, the neglected piece of the growth story is the management of waste generated by solar PV technology
as no discussions is happening on the issue.
Disaster in waiting
Recent researches show that cell manufacturing uses raw materials that pose health hazards among living
organisms. In addition, the entire value chain is fraught with processes and systems that can be a threat to the
environment. Even the extraction process of silicon or constituent elements causes environmental damages
when trapped, underground toxic gases escape into atmosphere. Thus, a systematic analysis will help us in
determining other potential sources of hazards.
Manufacturing Hazards
Crystalline Silica Cells
Manufacturing process requires chemicals like Hydrogen Chloride and Chlorosilanes, which are toxic and
explosive in its reaction with water. Silicon Tetrachloride is also produced during the process which is a skin
irritant and can cause burns if exposed in high concentrations.
Figure-5: Crystalline Silicon Generation Process11
In order to react the substances large temperatures are required that leads to energy waste. Sulfur hexafluoride
(SF6) is also a by-product in the process and is known for its more potent harmful greenhouse effect in
comparison to Carbon dioxide. Other constituents like ethyl vinyl acetate, nitrogen, hydrogen peroxide, titanium
dioxide etc too have been identified as hazardous.
Thin film Technology
The main element is cadmium which is known to have damaging effects on livers, lungs and kidneys. Also,
being new technology very limited information is available on the toxicity of cadmium telluride (CdTe).
Usage Hazards
Solar PV systems have complex electric circuitry and associated electrical systems like inverters, power
devices. There working is based on electromagnetic induction, which is known to have carcinogenic properties
on long term exposure.
Also, being an active circuit during solar insolation makes them very dangerous during fire as de-energizing is
very difficult. The elemental constituent, Ethyl Vinyl Acetate can easily form explosive mixtures with air under
such conditions.
Hazards at disposal stage
Components like Cadmium, Arsenic and Tellurium can interfere with the natural food chains because of their
toxicity and pose harmful long term consequences.
EU Classification/Labelling Dangerous Substances 12
has identified Cadmium as extremely toxic and
carcinogenic.
End-of-life hazards for Solar PV
This is an important issue which has so far missed the industry notice. Much of the waste generated can be
categorized as e-waste and requires sophisticated mechanisms for disposal and recycling. Also, being a
hazardous waste only certified agencies have the capability to handle this. But, Indian scenario is not very
promising as only 5% of e-waste is handled by organized sector. Main reasons for this lackadaisical case are
ignorant society, tardy policy making and lack of recycling capacity.
With these concerns any rise in e-waste due to solar PV will surely aggravate the condition.
Other Concerns
Land use pattern and utilization
Solar plants require large tracts of land for electricity generation, as per technical estimates roughly 5 to 10
acres of land generates 1 MW13
. Following this with JNNSM’s ambitious target of 20 GW, land requirement
will rise to a whopping figure of 20 million sq. mt. 14
India is already land starved and growing urbanization is
straining arable area.
Moreover, land acquisition process is very archaic and calls for revolutionary changes to make it equitable with
the concerns of dislodged population.
When large areas are made available for solar plants, no major policy steps have been implemented to highlight
concerns on theissue of adequate compensation. Also, exploitation can’t be ruled out at hands of private parties
when acquisition is done in absence of any laid guidelines.
Water balancing
Solar thermal runs on similar energy cycles like coal based plants and thus will require large volumes of water
for cooling of systems. This restricts the choice of sites for putting up solar thermals and forces presence in
vicinity of water sources. The current thought process is narrow in sense that it considers only sun-rich areas of
Rajasthan or Gujarat,, but with scarce water availability, there’s seems to a mismatch in resource mapping .
Also, water is needed for cleaning & maintenance purposes and once large areas get covered with panels there
will be a proportional rise in demand. This concern is also neglected by the policy makers.
Interference with desert ecosystem
Desert topography and ecology is very sensitive, any external influences can greatly affect the local bio-
diversity. Cell surfaces are very shiny and often deceive aquatic insects as water source where they can lay their
eggs15
. This can be a major detriment to the life-cycle of the insects and lead to their extinction. With each
organism playing a role in local food-chain, this missing portion can interfere with the entire ecological balance.
However, current planning being a macro approach is indifferent to these aspects of ecosystem.
Existing regulations
The Environment Impact Assessment (EIA) Notification, 2009 is a landmark legislation to safeguard
environment and mandates regulatory clearance before any industrial activity, but even it neglects solar PV
plants under its ambit. With respect to hazardous chemicals, various schedules under Hazardous Chemical
Rules have failed to include cadmium compounds, silane, argon, selenide gas. Unregulated emissions of these
can have harmful effects on the environment and when discharged to water bodies become more potent as it
then easily enter the food chain of living organisms.
Regulation in other nations
China Case
Society has started witnessing the ill-effects of irresponsible behaviour of Industry and subsequently discussions
have started to put more scrutiny and onus on the manufacturing industry. Even govt. has started to take of this
Figure-6: Silicon Tetrachloride dumping in Henan, China16
issue where in one case a plant of Zhejiang Jinko Solar company in Haining city had to stop production when
public protested about the huge untreated toxic waste resulting from factory compound.17
Californian case
As per the regulations, manufacturers are accountable through a pre-financed extended producer responsibility
scheme (EPR), which would promote eco-design and would fund the needed infrastructures for the PV module
recycling. 18
Subsequently, domestic recycling treatment will come under the regulation as a check on
irresponsible practices of illegal dumping and mishandling.19
The situation now is more tensed because SVTC (Silicon Valley Toxic Coalition) issued a report stating on the
toxicity levels of the main composite (cadmium and tellurium), which classifies the PV compounds as
hazardous waste. Therefore, authorities are considering the proposal for enforcing hazardous waste control
laws, through permit issuing and fee impositions (pre-financed collection scheme).20
,21
While waiting for the regulation’s final approval, Californian solar firms have begun planning and creating
coalitions to recycle used PV panels before leaching stage through various recycling methods suggested by the
Norwegian Geotechnical Institute (NGI).22
European case
European authorities have launched the EWL (European Waste Law), whose WEEE directive (waste for
electrical and electronic equipment) states that manufacturers must finance a system for collecting, processing,
recycling and disposing them (Take-Back policy). Moreover, producers, importers and distributors should give
incentives to design electrical and electronic equipment in a more environmentally efficient way. 23
Finally, increasing targets are fixed at a European level, for which treatment standards have to be met, as the
below regulation:
“Four years after the entry into force of the present directive, member states must collect annually 45% of the
average weight of electrical and electronic equipment placed on their national markets. Three years later,
member states are to achieve a 65% collection rate.”24
Thus, societies are at trending at different stages in their sensitization of the impending hazard.
Risk Life Cycle Assessment
It is very evident that India discussions are still nascent but other countries are gradually moving up the
trajectory. And with information becoming more easily accessible in digital age, there will not be substantial lag
when issue becomes pertinent in domestic arena. Now, when Indian manufacturers are facing existential threats
it is quite obvious that they too have failed to incorporate this non-market strategy. However, industry in
developed nations has started to include these developments as part of strategy to thwart competition from
cheaper and non-standard Chinese imports.
Figure-7: Issue Development Life Cycle Process25
Policy imperatives for India
The growing debate at world level presents high point for India to start rationalizing its solar mission policy.
Basic calculation to identify the potential waste India is likely to face,
Solar cell dimension = 1642 x 979 x 38 (mm) 26
Volume of one panel = 61085.68 cm3
Weight = 19 Kg
Wattage = 250 W 27
Number of panel for 1 MW = 4000
1 ton = 907185 g
Waste from 1 MW = 83 ton
When India fulfills solar mission’s commitment of 20 GW
Potential e-waste = 16, 60,000 tons
Thus, when the debate sets in, there will be amendment to all existing legislations like CRZ notification,
Hazardous Waste Rules, Chemical rules, factory rules to prevent the likely impact on humans and environment.
And this presents an ideal case for domestic manufacturers to proactively shape their sustenance by being
ecologically sensitive.
Domestic Manufacturing: Case for Sustainability
Domestic manufacturing lacks scale and is very fragmented. With majority of silicon wafers still procured
through imports, manufacturing is mainly a downstream module assembly process.
As industry faces challenges of limited revenue streams and impending competition, it has cut down investment
in development of new technology.
Although, govt. has included the concept of domestic content requirement (DCR) under solar mission targets
but imported components are finding more takers as they lower the cost of electricity generation and makes
solar energy competitive in relation to fossil fuels.
Figure-8: Import reliance in India’s solar story28
Domestic Manufacturer: Moser Baer
Established in New Delhi, Moser Baer is one of the leading PV modules manufacturers in India. The Strategic
Business Unit has different model from its local competitors who operates as EPC (Engineering, Procurement
and Construction) contractors.
Figure-9: Business Models in Indian Solar Industry
EPC contractor imports various parts and components, mostly from China, for their low cost advantage.
However, imported parts have concerns of quality, performance and longevity. The components are then
assembled and integrated and solar photovoltaic module is made ready for installation.
The value chain of Moser Baer (MB) is sensibly different and allows them to have a better control over
production costs, manufacturing processes, quality control and technological improvements. Moreover, their
manufactured items respect international quality standards and international certifications (ISO 9001:2000, SA
8000 and IEC certification). Also, thanks to its strategic alliances with American solar technology laboratories
and corporations, as Solfocus (high concentration photovoltaic tech.), Solaria (high efficiency solar tech.), Stion
Corporation (low cost high efficiency solar thin film panel) and HGS (High Gain Solar, producing durable and
easy to deploy solar systems), MB is able to complement the knowledge and capabilities. This allows the firm
to be at the forefront of technology and quality. However some compounds are still imported (from America
and Europe) because of the technological specificity and then assembled to be sold in domestic and
international market.29 30
MB implements as well recycling policies. As a member of PV Cycle, an international entity who promotes
voluntary waste management and recycling policies, Moser Baer is implementing a take-back policy which
applies nowadays just for the PV modules internationally sold. This initiative guarantees that every module at
the end of its life or warranty is recycled and its environmental impact minimized. This however, is not
practiced in India due to the lack of regulations. 31
Issues & concerns
Although, Moser Baer is a reckoning force in India, its plats are running below capacity. This is because of
higher module cost in comparison to Chinese imports, lower order book cascades into lesser plant utilization
and further higher cost. Another case is the dependency on imports of silicon wafers which exposes the firm to
exchange rate risks.
China meanwhile is going aggressive on capacity expansion and currently produces 3232
times more than what
local market demands. This additional capacity when operating under scale makes a threatening competitive
case for any countries domestic manufacturers as experienced in India.
Figure-10: Domestic manufacturing vis-à-vis global situation33
Non- Market factor: Stakeholder Analysis
Deriving learnings from stakeholder position in China and developed nations, gradual shift happens in the
positioning of various stakeholders. Under dormant case, courts and pollution regulators operate in the fringe
category and entire operating scope is managed by EPC, domestic manufacturers and government. But, when
India reaches Stage –III (fig.7), society activists will become stronger and shape the govt. policy through
collective voice and harsh steps will fall in place to regulate the sector.
Figure-9: Stakeholder Evolution34
Any such step will be life savior for domestic manufacturers as they have better technology and standard
products. But, analysis highlights that govt. role will mostly be reactive in nature and with no time certainty
many domestic manufacturers might fold by the time, succumbing to import competition. Thus, there is an
opportunity for Indian producers to take onus and initiate the discussion till now neglected from policy ambit.
Cost Benefit Analysis
A typical cost benefit analysis will more objectively validate this argument of how domestic manufacturers
should try and reclaim their share of market within the realms of sustainability. As per CERC benchmarkt,
installation costs have decreased over the years and driver is the 62% decrease in cost of PV module (import
phenomena). The guideline also misses any waste management cost.

Table-5: CERC benchmark capital cost for solar PV plants (as on 25/10/ 2012)35
Kerala Pollution Control Board has suggested that a capex of 10 crore is required for treating 1, 50,000 ton of
e-waste.36
Now, 1 MW generates = 83 ton of e-waste (proved earlier)
Therefore, capex cost per MW = Rs (10, 00, 00,000 ÷ 1, 50,000) x 83 = Rs 55,333
Also, we can find present value of investment that will be required at the end of life waste treatment for 1 MW
from waste management cost in U.K = Rs 12000 per ton (E-waste report in India)37
.
Using a discount rate of 9%, present value varies significantly with expected working life.

Table-6: Present Value of end-of-life recycling cost
Conclusion
A careful observation presents this interesting point where treatment cost can vary for a player if his product
doesn’t function satisfactorily over stated lifetime. And, for any player per MW treatment plant installation cost
is less in comparison to per MW treatment cost.
Thus, a domestic manufacturer can pursue this idea of plant installation rather than accounting for treatment
cost. With current lack in capacity for e-waste treatment any plant can have alternate feeders for capacity
utilization. On the other hand, the imported product quality is unproven and concerns exist regarding
operational life. With no objective estimation, factoring for treatment cost is fraught with heavy risks and once
some parameter are developed, incorporation of ROI will push the prices for these imported components.
Indian products on the other hand have international certifications and reliable working life, which makes any
such waste treatment accounting a precise activity. According to industry sources any cost in excess of 50 Lakh
for a plant (avg. plant size in India is 15 MW) can bring domestic manufacturing at par competition with
cheaper imports.
Thus, Indian solar case can be a classic example where interplay of environment concern and sustainability is
markedly evident. Here, survival necessitates integration of non-market strategy and proactive engagement to
change industry course.
Recommendation
Following are some suggestion on how manner of strategy implementation based on time-lines and their
reasonability in achieving the intended objectives.
a) Initiate discussions on waste management
This strategy could be initiated on a short-term perspective. Replicating the Californian model, the company
would introduce the issue to the governmental authorities. With the debate, society will be also aware and more
involved in it. As a consequence, more efficient and durable products will be developed and will make domestic
manufacturers more competitive, thanks to their superiority in quality, performance and durability. Therefore,
this action will revitalize the Indian PV modules manufacturing sector and will promote the development of
new technologies for the recycling process.
The involved stakeholders will be:
- domestic manufacturers: new product developments and R&D expenditures;
- government : policy creation and implementation;
- pollution regulators: participation in the regulation discussion and set up of new standards.
b) Product insurance and take back clause
Moser Baer will provide a longer guarantee certifying the quality and the longevity (20 years) of its products.
This will redefine the industry standards and self-selection dynamics will force poor quality products (the
imported ones) to wind up. This will revitalize the domestic industry and strengthen the case of better quality
domestic components.
The stakeholders involved would be: domestic manufacturers, government, and consumers.
c) R&D investments
On a short/medium term, the company should invest more in R&D in order to improve the quality, longevity
and sustainability of the components, which will have more acceptability in the market. This will also help the
industry to gain learning curve advantage when more advanced technologies emerge.
d) Collaboration on common treatment plants
On a medium term perspective, the various Indian manufacturers should join their forces and invest collectively
in recycling and treatment facilities (as it is currently done in California, US). Moreover, they could lease their
recycling services to the EPCs or other e-waste generators at higher price. This will be an alternative income
stream, which could then be reinvested in the infrastructure improvement.
e) Switch to other renewable technologies
On a long run perspective, it would be necessary to convert the solar energy technologies into other ways as: 4th
generation nuclear plants, bio-fuels, small hydro, wind-offshore, geo-thermal which have tremendous potential.
However, such a shift is likely to take quite a long time to realize but will be beneficial in terms of waste
management and minimization.
f) Integrated Eco-industrial Park
By following the Kalundborg Eco-Industrial Park example, the waste derived from PV modules becomes the
raw material for another industry or re-enters in the value chain. The glass, for example, could be used in other
factories while the toxic compound could be chemically treated and recycled properly. Of course this could be
done on a more long-term perspective, but this model could have great potential for minimizing the
environmental impact and increasing the productivity of diversified industries.38

  • 3. Indian Energy Scenario Energy demand in India has been growing over the years and country is now placed fourth in terms of primary energy consumption. On comparing this with world average of 1797 kilograms of oil equivalent (kgoe), India's per capita consumption of 585 kilograms of oil equivalent (kgoe) is very low. But, as per Planning Commission estimates consumption would rise to to 738.07 mtoe by 2016-171 and with supply side bottlenecks there will be about 38 percent import reliance. Country Primary Energy Consumption China 2210.3 mtoe United States 2205.9 mtoe Russian Federation 644.4 mtoe India 487.6 mtoe Japan 474 mtoe Country KGOE United States 7034 Russian Federation 4559 Japan 3707 UK 3184 China 1698 Brazil 1240 India 585 World 1797 Table-1: Primary Energy Consumption of Top Five Countries (2009)2 Table-2: Per Capita Energy Consumption (2009)3 Energy consumption in India is highly dependent on hydrocarbon fuels with only 10% made up by cleaner and renewable sources. Figure-1: Indian Energy Mix 4 Now, with huge growth in projected demands and impending import dependence, it seems reasonable that emphasis needs to be given on sustainable abundant sources of energy. Energy Security Over the years challenges have emerged with lack in domestic coal production mainly attributed to infrastructure constraints, also there are concerns of environmental in case of large hydro plants, thermal power plant emissions and then heightened nuclear risk after Fukushima disaster. With existing supply-demand
  • 4. imbalance in range of 12.7% peak deficits, situation is likely to worsen in near future. Add to it, 50% of population has little or no access to commercial and majority others face erratic supplies. To address all these requirements it is necessary to arrive at a prudent energy mix by harnessing renewable sources which are resourceful domestically. However, high costs of energy generation associated with renewable sources are a major restraint but supportive government policies will allow it to compete economically with fossil fuels over time. Integrated Energy Policy, 2006 was the first formal step by Indian govt. to rationalize domestic energy mix. This was followed by institution of a full-fledged Ministry on New and Renewable Energy (MNRE) which is a nodal agency to facilitate implementation of all programmes on renewable energy resources. Renewable energy sources in India Renewable energy can be derived from natural sources like water, sun, wind, geothermal, tidal, biofuels etc. Being inexhaustible and replenish able source, they are clean and have no harmful effects on natural ecosystem. As per govt. data, wind energy is the largest harnessed renewable source in India. But, supporting policies are increasing contribution from Solar for past few years. Figure-2: Contribution of various RES (on-grid) Source: www.mnre.gov.in (as on 30/9/2013) Solar Energy Annually about 5,000 trillion kWh5 of solar energy is incident on India with average insolation of about 4-7 kWh per sq. m per day over most of the land area. This makes it technologically feasible to convert this huge reservoir of energy efficiently into heat and electricity by using solar PV and solar thermal systems. Also, geographical location of India is such that major land mass receives the average insolation for 5 hours daily and this presents a case for easy scalability. National Solar Mission6 Given the context, government embarked on the ambitious goal by launching Jawaharlal Nehru National Solar Mission. The objective was to develop solar energy as a competitive alternative for hydrocarbons based energy sources. Additional advantage was that change in energy mix, will make development more inclusive as off- grid systems will empower marginalized and deprived people. The mission also earmarked goals for promoting R&D program in collaboration with leading researchers in the field. Mission targets are: 68% 13% 4% 8% 7% 0.34% Wind Small Hydro Biomass Bagasse Cogeneration Solar PV Other
  • 5. Table-3: JNNSM Capacity Addition Target7 Domestic manufacturing India’s Solar PV industry is dependent on imported components, major one being the silicon wafers. And to promote domestic manufacturing, the mission set a target of 4-5 GW equivalent manufacturing capacity by 2020. By March 2013, the total capacity has touched 2000 MW as per MNRE announcement.8 The break-up of different components are, Table-4: Manufacturing Facility9 However, India doesn’t have any poly-silicon production capacity and no capability in solar thermal projects; but with new policies and sector will get boost to develop these alternate technologies. Solar cell Technology: Future Outlook Currently crystalline silicon is the most common technology, and its manufacturing processes are similar to that of electronic circuitry industry. But, gradual advancements and better efficiencies are making the “thin-film” cells as preferred choices. c-Si : Crystalline Silicon a-Si : Amorphous Silicon CIS : Copper Indium Selenide CIGS : Copper Indium Gallium Selenide CdTe : Cadmium Telluride Figure-4: Solar PV Module Technology10 However, the neglected piece of the growth story is the management of waste generated by solar PV technology as no discussions is happening on the issue.
  • 6. Disaster in waiting Recent researches show that cell manufacturing uses raw materials that pose health hazards among living organisms. In addition, the entire value chain is fraught with processes and systems that can be a threat to the environment. Even the extraction process of silicon or constituent elements causes environmental damages when trapped, underground toxic gases escape into atmosphere. Thus, a systematic analysis will help us in determining other potential sources of hazards. Manufacturing Hazards Crystalline Silica Cells Manufacturing process requires chemicals like Hydrogen Chloride and Chlorosilanes, which are toxic and explosive in its reaction with water. Silicon Tetrachloride is also produced during the process which is a skin irritant and can cause burns if exposed in high concentrations. Figure-5: Crystalline Silicon Generation Process11 In order to react the substances large temperatures are required that leads to energy waste. Sulfur hexafluoride (SF6) is also a by-product in the process and is known for its more potent harmful greenhouse effect in comparison to Carbon dioxide. Other constituents like ethyl vinyl acetate, nitrogen, hydrogen peroxide, titanium dioxide etc too have been identified as hazardous. Thin film Technology The main element is cadmium which is known to have damaging effects on livers, lungs and kidneys. Also, being new technology very limited information is available on the toxicity of cadmium telluride (CdTe). Usage Hazards Solar PV systems have complex electric circuitry and associated electrical systems like inverters, power devices. There working is based on electromagnetic induction, which is known to have carcinogenic properties on long term exposure. Also, being an active circuit during solar insolation makes them very dangerous during fire as de-energizing is very difficult. The elemental constituent, Ethyl Vinyl Acetate can easily form explosive mixtures with air under such conditions.
  • 7. Hazards at disposal stage Components like Cadmium, Arsenic and Tellurium can interfere with the natural food chains because of their toxicity and pose harmful long term consequences. EU Classification/Labelling Dangerous Substances 12 has identified Cadmium as extremely toxic and carcinogenic. End-of-life hazards for Solar PV This is an important issue which has so far missed the industry notice. Much of the waste generated can be categorized as e-waste and requires sophisticated mechanisms for disposal and recycling. Also, being a hazardous waste only certified agencies have the capability to handle this. But, Indian scenario is not very promising as only 5% of e-waste is handled by organized sector. Main reasons for this lackadaisical case are ignorant society, tardy policy making and lack of recycling capacity. With these concerns any rise in e-waste due to solar PV will surely aggravate the condition. Other Concerns Land use pattern and utilization Solar plants require large tracts of land for electricity generation, as per technical estimates roughly 5 to 10 acres of land generates 1 MW13 . Following this with JNNSM’s ambitious target of 20 GW, land requirement will rise to a whopping figure of 20 million sq. mt. 14 India is already land starved and growing urbanization is straining arable area. Moreover, land acquisition process is very archaic and calls for revolutionary changes to make it equitable with the concerns of dislodged population. When large areas are made available for solar plants, no major policy steps have been implemented to highlight concerns on theissue of adequate compensation. Also, exploitation can’t be ruled out at hands of private parties when acquisition is done in absence of any laid guidelines. Water balancing Solar thermal runs on similar energy cycles like coal based plants and thus will require large volumes of water for cooling of systems. This restricts the choice of sites for putting up solar thermals and forces presence in vicinity of water sources. The current thought process is narrow in sense that it considers only sun-rich areas of Rajasthan or Gujarat,, but with scarce water availability, there’s seems to a mismatch in resource mapping . Also, water is needed for cleaning & maintenance purposes and once large areas get covered with panels there will be a proportional rise in demand. This concern is also neglected by the policy makers. Interference with desert ecosystem Desert topography and ecology is very sensitive, any external influences can greatly affect the local bio- diversity. Cell surfaces are very shiny and often deceive aquatic insects as water source where they can lay their eggs15 . This can be a major detriment to the life-cycle of the insects and lead to their extinction. With each organism playing a role in local food-chain, this missing portion can interfere with the entire ecological balance. However, current planning being a macro approach is indifferent to these aspects of ecosystem. Existing regulations The Environment Impact Assessment (EIA) Notification, 2009 is a landmark legislation to safeguard environment and mandates regulatory clearance before any industrial activity, but even it neglects solar PV

Unregulated emissions of these can have harmful effects on the environment and when discharged to water bodies become more potent as it then easily enter the food chain of living organisms. Regulation in other nations China Case Society has started witnessing the ill-effects of irresponsible behaviour of Industry and subsequently discussions have started to put more scrutiny and onus on the manufacturing industry. Even govt. has started to take of this Figure-6: Silicon Tetrachloride dumping in Henan, China16 issue where in one case a plant of Zhejiang Jinko Solar company in Haining city had to stop production when public protested about the huge untreated toxic waste resulting from factory compound.17 Californian case As per the regulations, manufacturers are accountable through a pre-financed extended producer responsibility scheme (EPR), which would promote eco-design and would fund the needed infrastructures for the PV module recycling. 18 Subsequently, domestic recycling treatment will come under the regulation as a check on irresponsible practices of illegal dumping and mishandling.19 The situation now is more tensed because SVTC (Silicon Valley Toxic Coalition) issued a report stating on the toxicity levels of the main composite (cadmium and tellurium), which classifies the PV compounds as hazardous waste. Therefore, authorities are considering the proposal for enforcing hazardous waste control laws, through permit issuing and fee impositions (pre-financed collection scheme).20 ,21 While waiting for the regulation’s final approval, Californian solar firms have begun planning and creating coalitions to recycle used PV panels before leaching stage through various recycling methods suggested by the Norwegian Geotechnical Institute (NGI).22 European case European authorities have launched the EWL (European Waste Law), whose WEEE directive (waste for electrical and electronic equipment) states that manufacturers must finance a system for collecting, processing, recycling and disposing them (Take-Back policy). Moreover, producers, importers and distributors should give incentives to design electrical and electronic equipment in a more environmentally efficient way. 23
  • 9. Finally, increasing targets are fixed at a European level, for which treatment standards have to be met, as the below regulation: “Four years after the entry into force of the present directive, member states must collect annually 45% of the average weight of electrical and electronic equipment placed on their national markets. Three years later, member states are to achieve a 65% collection rate.”24 Thus, societies are at trending at different stages in their sensitization of the impending hazard. Risk Life Cycle Assessment It is very evident that India discussions are still nascent but other countries are gradually moving up the trajectory. And with information becoming more easily accessible in digital age, there will not be substantial lag when issue becomes pertinent in domestic arena. Now, when Indian manufacturers are facing existential threats it is quite obvious that they too have failed to incorporate this non-market strategy. However, industry in developed nations has started to include these developments as part of strategy to thwart competition from cheaper and non-standard Chinese imports. Figure-7: Issue Development Life Cycle Process25 Policy imperatives for India The growing debate at world level presents high point for India to start rationalizing its solar mission policy. Basic calculation to identify the potential waste India is likely to face, Solar cell dimension = 1642 x 979 x 38 (mm) 26 Volume of one panel = 61085.68 cm3 Weight = 19 Kg Wattage = 250 W 27 Number of panel for 1 MW = 4000 1 ton = 907185 g Waste from 1 MW = 83 ton When India fulfills solar mission’s commitment of 20 GW Potential e-waste = 16, 60,000 tons
  • 10. Thus, when the debate sets in, there will be amendment to all existing legislations like CRZ notification, Hazardous Waste Rules, Chemical rules, factory rules to prevent the likely impact on humans and environment. And this presents an ideal case for domestic manufacturers to proactively shape their sustenance by being ecologically sensitive. Domestic Manufacturing: Case for Sustainability Domestic manufacturing lacks scale and is very fragmented. With majority of silicon wafers still procured through imports, manufacturing is mainly a downstream module assembly process. As industry faces challenges of limited revenue streams and impending competition, it has cut down investment in development of new technology. Although, govt. has included the concept of domestic content requirement (DCR) under solar mission targets but imported components are finding more takers as they lower the cost of electricity generation and makes solar energy competitive in relation to fossil fuels. Figure-8: Import reliance in India’s solar story28 Domestic Manufacturer: Moser Baer Established in New Delhi, Moser Baer is one of the leading PV modules manufacturers in India. The Strategic Business Unit has different model from its local competitors who operates as EPC (Engineering, Procurement and Construction) contractors. Figure-9: Business Models in Indian Solar Industry
  • 11. EPC contractor imports various parts and components, mostly from China, for their low cost advantage. However, imported parts have concerns of quality, performance and longevity. The components are then assembled and integrated and solar photovoltaic module is made ready for installation. The value chain of Moser Baer (MB) is sensibly different and allows them to have a better control over production costs, manufacturing processes, quality control and technological improvements. Moreover, their manufactured items respect international quality standards and international certifications (ISO 9001:2000, SA 8000 and IEC certification). Also, thanks to its strategic alliances with American solar technology laboratories and corporations, as Solfocus (high concentration photovoltaic tech.), Solaria (high efficiency solar tech.), Stion Corporation (low cost high efficiency solar thin film panel) and HGS (High Gain Solar, producing durable and easy to deploy solar systems), MB is able to complement the knowledge and capabilities. This allows the firm to be at the forefront of technology and quality. However some compounds are still imported (from America and Europe) because of the technological specificity and then assembled to be sold in domestic and international market.29 30 MB implements as well recycling policies. As a member of PV Cycle, an international entity who promotes voluntary waste management and recycling policies, Moser Baer is implementing a take-back policy which applies nowadays just for the PV modules internationally sold. This initiative guarantees that every module at the end of its life or warranty is recycled and its environmental impact minimized. This however, is not practiced in India due to the lack of regulations. 31 Issues & concerns Although, Moser Baer is a reckoning force in India, its plats are running below capacity. This is because of higher module cost in comparison to Chinese imports, lower order book cascades into lesser plant utilization and further higher cost. Another case is the dependency on imports of silicon wafers which exposes the firm to exchange rate risks. China meanwhile is going aggressive on capacity expansion and currently produces 3232 times more than what local market demands. This additional capacity when operating under scale makes a threatening competitive case for any countries domestic manufacturers as experienced in India. Figure-10: Domestic manufacturing vis-à-vis global situation33
  • 12. Non- Market factor: Stakeholder Analysis Deriving learnings from stakeholder position in China and developed nations, gradual shift happens in the positioning of various stakeholders. Under dormant case, courts and pollution regulators operate in the fringe category and entire operating scope is managed by EPC, domestic manufacturers and government. But, when India reaches Stage –III (fig.7), society activists will become stronger and shape the govt. policy through collective voice and harsh steps will fall in place to regulate the sector. Figure-9: Stakeholder Evolution34 Any such step will be life savior for domestic manufacturers as they have better technology and standard products. But, analysis highlights that govt. role will mostly be reactive in nature and with no time certainty many domestic manufacturers might fold by the time, succumbing to import competition. Thus, there is an opportunity for Indian producers to take onus and initiate the discussion till now neglected from policy ambit. Cost Benefit Analysis A typical cost benefit analysis will more objectively validate this argument of how domestic manufacturers should try and reclaim their share of market within the realms of sustainability. As per CERC benchmarkt, installation costs have decreased over the years and driver is the 62% decrease in cost of PV module (import phenomena). The guideline also misses any waste management cost.

  • 13. Kerala Pollution Control Board has suggested that a capex of 10 crore is required for treating 1, 50,000 ton of e-waste.36 Now, 1 MW generates = 83 ton of e-waste (proved earlier) Therefore, capex cost per MW = Rs (10, 00, 00,000 ÷ 1, 50,000) x 83 = Rs 55,333 Also, we can find present value of investment that will be required at the end of life waste treatment for 1 MW from waste management cost in U.K = Rs 12000 per ton (E-waste report in India)37 . Using a discount rate of 9%, present value varies significantly with expected working life. Expected Operating Life Present Value of end-of-life recycling cost (Lakh/MW) 5 yrs 10 yrs 15 yrs 20 yrs 6.49 4.22 2.74 1.78 Table-6: Present Value of end-of-life recycling cost Conclusion A careful observation presents this interesting point where treatment cost can vary for a player if his product doesn’t function satisfactorily over stated lifetime. And, for any player per MW treatment plant installation cost is less in comparison to per MW treatment cost. Thus, a domestic manufacturer can pursue this idea of plant installation rather than accounting for treatment cost. With current lack in capacity for e-waste treatment any plant can have alternate feeders for capacity utilization. On the other hand, the imported product quality is unproven and concerns exist regarding operational life. With no objective estimation, factoring for treatment cost is fraught with heavy risks and once some parameter are developed, incorporation of ROI will push the prices for these imported components. Indian products on the other hand have international certifications and reliable working life, which makes any such waste treatment accounting a precise activity. According to industry sources any cost in excess of 50 Lakh for a plant (avg. plant size in India is 15 MW) can bring domestic manufacturing at par competition with cheaper imports. Thus, Indian solar case can be a classic example where interplay of environment concern and sustainability is markedly evident. Here, survival necessitates integration of non-market strategy and proactive engagement to change industry course. Recommendation Following are some suggestion on how manner of strategy implementation based on time-lines and their reasonability in achieving the intended objectives. a) Initiate discussions on waste management This strategy could be initiated on a short-term perspective. Replicating the Californian model, the company would introduce the issue to the governmental authorities. With the debate, society will be also aware and more involved in it. As a consequence, more efficient and durable products will be developed and will make domestic
  • 14. manufacturers more competitive, thanks to their superiority in quality, performance and durability. Therefore, this action will revitalize the Indian PV modules manufacturing sector and will promote the development of new technologies for the recycling process. The involved stakeholders will be: - domestic manufacturers: new product developments and R&D expenditures; - government : policy creation and implementation; - pollution regulators: participation in the regulation discussion and set up of new standards. b) Product insurance and take back clause Moser Baer will provide a longer guarantee certifying the quality and the longevity (20 years) of its products. This will redefine the industry standards and self-selection dynamics will force poor quality products (the imported ones) to wind up. This will revitalize the domestic industry and strengthen the case of better quality domestic components. The stakeholders involved would be: domestic manufacturers, government, and consumers. c) R&D investments On a short/medium term, the company should invest more in R&D in order to improve the quality, longevity and sustainability of the components, which will have more acceptability in the market. This will also help the industry to gain learning curve advantage when more advanced technologies emerge. d) Collaboration on common treatment plants On a medium term perspective, the various Indian manufacturers should join their forces and invest collectively in recycling and treatment facilities (as it is currently done in California, US). Moreover, they could lease their recycling services to the EPCs or other e-waste generators at higher price. This will be an alternative income stream, which could then be reinvested in the infrastructure improvement. e) Switch to other renewable technologies On a long run perspective, it would be necessary to convert the solar energy technologies into other ways as: 4th generation nuclear plants, bio-fuels, small hydro, wind-offshore, geo-thermal which have tremendous potential. However, such a shift is likely to take quite a long time to realize but will be beneficial in terms of waste management and minimization. f) Integrated Eco-industrial Park By following the Kalundborg Eco-Industrial Park example, the waste derived from PV modules becomes the raw material for another industry or re-enters in the value chain. The glass, for example, could be used in other factories while the toxic compound could be chemically treated and recycled properly. Of course this could be done on a more long-term perspective, but this model could have great potential for minimizing the environmental impact and increasing the productivity of diversified industries.38
