To promote the grid connected SPV rooftop and small SPV power generating plants among the residential, community, institutional, industrial and commercial establishments.
2. Solar Advisory Services
Power / Electricity reliability, costs and availability
is a challenge -
• Many institutions / industry / factories / commercial
complexes pay ever increasing costs of electricity
without a visible control on their future energy bills.
• Many factories compulsorily run on diesel
generators during peak hours as per local ESCOM
rules, example Tamil Nadu – evening 6 pm to 10
pm EB power cannot be used. At present diesel
prices, the cost of electricity in such cases is Rs 18/-
to Rs 21/- per unit, apart from daily cash outflow
basis.

• For many homes, farm houses, irrigation pumps
are without power for many hours requiring a
Hybrid solution of grid with back up.
• New conventional power sources of electricity
not on anvil.
• Hydro power suspect in India, depending on
regular monsoons.
• Current coal prices are Rs. 5/Kg on regular e-
auctions for industries and sometimes Rs. 8/Kg
when supply is tight. Prices will only go up!
4. Why Advantage Solar?
Solar PV offers power at Rs.6-7/KWh during daytime use, as
either grid connected exporting to grid or as captive depending
on size of plant. In case of use with batteries for critical loads,
can be configured separately.
Diesel
• Diesel power costs Rs. 18-21/KWh, (incl logistics,
maintenance) making solar power much cheaper, and also
entails daily cash outflow.
• The price of diesel fuel has increased 300% since 2002 and
46% since 2010 and is going to be market driven increasing
un-predicatability of energy costs / basket for future.
Return on Investment is under 2 years….
Grid
• Solar power may be cheaper than grid power, depending on
the customer category and jurisdiction as HT(1), HT(2) etc.
For offices and homes tariff slabs are increasing each year…
Return on Investment is under 5 years…
5. How PV system installed?
• Solar panels can be mounted on
unshaded roofs, walls or ground using
mounting systems.
• DC cables connect panels in series to
form strings.
• These strings then feedback to the
inverter usually located inside the
building as close to the solar panels as
possible.
• Every KW of electricity will be recorded
on your generation meter.
• A 4KW domestic PV system will usually
take 1 day to install.
6. How does PV work?
• Photovoltaics is the direct conversion of light
into electricity. A number of solar cells
electrically connected to each other and mounted
in a support structure or frame is called a
photovoltaic module, and multiple modules can
be wired together to form an array. Photovoltaic
modules and arrays produce direct-current (dc)
electricity.
• Solar panels capture sunlight and convert it to
DC electricity.
• Your solar system's inverter converts that energy
to an AC current that can power your home or
business.
• Excess energy or energy that you don’t use goes
back to the utility grid and creates an electricity
“credit” for you to use at a later date.
7. Process for Net Metering….
• This is coordinated by us. Different rules of states apply with regard to
system sizing based on distribution transformers. Only Karnataka allows
preferential tariff payment for surplus power exported as of now. Other
states allow carry forward for a year.
• Process : on line application with all the below mentioned documents –
1. Applicant Type
2. Name Of Applicant with Contact details
3. Existing ESCOM Installation Details
4. System size proposed.
5. Rooftop details
6. Subsidy “no claim” declaration to be eligible for tariff given.
9. Rooftop Solar Systems - Advantages
• General sizes of under 10 KW, 11-50 KW and above 50 KW as per
Government categorisation.
• Low Gestation period enabling quick benefit to clients.
• Ease of integration into existing systems of either Grid or DG.
• No permissions required if connected on load side with battery for
critical loads with no grid export.
• No land acquisition or evacuation problems.
• Higher financial reliability with visible and predictable cash flows
for energy either in savings or set offs or revenue income if
exported.
• Huge savings option against DG which caters to 20 GW in India.
Savings to the Nation and protects environment.
• Indirect cooling of building top floor as heat is taken away to great
extent by solar panels.
10. Benefits of Solar
• Forget about electricity bill for next 25 years and power tariff increase.
• Earn money for every unit of power pumped to grid @Rs.9.56/unit.
• As a business owner if you are installing solar PV you can claim 80% of the
depreciation in the first year.
• Any income received from solar energy is tax exempt for next 10 years.
11. Calculations for Rooftop Solar Plant
• Roof Area required : Approximately 100 square feet per 1
KW, clear shadow free area. If sloped roof, then south
facing direction slope required with above requirements.
• Tile / Asbestos / Sheet roofs – Solar panels can be installed
on these roofs, south facing slope, with accessories. Roof
load bearing truss to be checked along-with ageing.
• Area /Weight of solar panels – Generally 16 kgs per square
metre. We can help design ideal roofing structure if roof
area is to be used below for other possible useful purposes
of client.
• System Sizing : We can provide the ideal system sizing for
getting good return on investment after site survey inputs
and interaction.
12. Rooftop Power Incentives
• Fiscal benefits to industries – through accelerated
depreciation.
• No separate permissions for LT load side integration if no
grid export (as solar UPS). Quick roll out time.
• In case of grid connected system, surplus power can be
exported with suitable permissions and government pays Rs
9.56 per unit for such power in Karnataka. In other states,
power exported is set off against consumption with carry
forward for a period of 1 year.
• Presently no subsidies at central level.
• Lower cost of equipment at LT level, bringing down capital
and installation costs.
