2. Why Floating PV?
Ever increasing power demand & depletion of fossil
fuels.
Leads to shift our focus to renewable energy sources.
Wind & Hydro RE sources are area specific.
PV can be installed at any place.
Major issue of Solar PV is requirement of land.
But floating solar can be installed on any water
bodies.
Floating solar PV results in decrease in cost and will
increase amount of generation due to cooling effect of
water.
3. CONCEPT
Floating Solar Power is innovative concept in energy
technology to meet the needs of our time.

4. Components of Floating PV
Floating System: A floating body (Structure +
Floater) that allows installation of PV module.
Mooring System: This allows to adjust water level
fluctuations while maintaining its position.
PV System: PV Generation equipment, similar to
electric junction boxes, that are installed on top of
floating system.
Underwater Cable: To transfer generated power to
substation.
5. K-water 100 kW
K- water installed 100 kW floating PV on the water
surface of Hapcheon water reservoir in 2011.
6. K- water 500 k W
After successful installation of 100 kW system K-
water installed 500 kW PV system on another location
at same dam.
7. Performance Analysis
100 kW PV at Hapcheon is forming 33 degree tilt &
its installed capacity is 99.36 kW, composed of 414
240W modules
8. Performance Analysis
Data is collected from Jan 2012 to Dec 2012.
Monthly average generated quantity 10,852 kWh
Fig : Performance Analysis graph
9. Performance Analysis
500 kW PV system forming 33 degree tilt, installed
capacity 496.8 kW composed of 2070 240 modules.
Monthly generated Avg. quantity form Oct. 2012 to
Mar. 2013 was 55208 kWh.
10. Comparison Floating PV & Overland PV
Floating solar panels( Blue) having 10.3 % more
efficient than overland system.

13. GOVT. OF INDIA INITIATIVES
Policy & Regulatory framework
ELECTRICITY ACT 2003 : Most transformational & dynamic act till
date includes laid guidelines for Renewable energy.
SECTION 61(h): While specifying terms and condition for tariff
determination the commission shall consider the promotion of
generation from renewable energy sources.
SECTION 86(1) (e): State commission shall promote generation of
Electricity from renewable energy sources. It shall be done by providing
grid connectivity & sale of Electricity to anyone.
NATIONAL ELECTRICITY POLICY 2005 :
SECTION 6.4 : This section states that in present stage non
conventional and conventional energy cannot compete at same similar
tariff and hence power shall be procured from non-conventional sources
at preferential tariff as determined by appropriate commission.
14. GOVT. OF INDIA INITIATIVES
Policy & Regulatory framework
Amendment of National tariff policy for Solar
specific RPO’s.
Solar specific RPO’s – 025 % in 2013 to 3 % by 2022.
REC mechanism .
Encourage state specific solar policies.
State wise RPO orders by Regulators.
Exemption for Environmental clearance for Solar
Power Projects.
15. Jawaharlal Nehru National Solar Mission (JNNSM)
Launched by Govt. of India in January 2011.
One of the major initiative at global level in
promotion of Solar energy technologies.
Mission aims to achieve grid tariff parity by 2022.
Large scale utilization, rapid diffusion and
deployment at a scale which leads to cost reduction.
R&D pilot projects and Technology Demonstration.
16. JNNSM Batch I Bidding Result Summary
Average tariff for selected projects was 1216
paisa/kWh which was 32% lower than CERC approved
benchmark tariff 1791 paisa/kWh.
In a Batch I a total of 204 MW capacity grid
connected solar power projects have been
commissioned.
17. Maharashtra Model Solar Policy
Maharashtra has reasonably high solar insolation 4-5
kWh/sq. meter with 280-300 clear sunny days.
Eastern Maharashtra considered to be most suitable
region for solar power projects
OBJECTIVE
To generate 1000 MW of Solar energy by 2016.
To achieve grid parity by 2016 .
Promotion of R&D and facilitation of technology
transfer.
Promotion of local manufacturing facilities.
19. Maharashtra Model Solar Policy
Subsidy under each project will be distributed into
three installments by state government.
20. Maharashtra Model Solar Policy
Criteria to avail benefits under the policy
Project developer should not procure any
incentives/ subsidy from central government.
PPA’s should be singed with MAHADISCOM.
Capacity Utilization Factor of Solar PV should be
more than 19% for initial two years of installation.
An audited detailed report and energy generation
report should be submitted to MEDA.
21. Financial Modeling of Solar PV
Capital Cost: Normative Capital cost INR 700 Lakhs/MW for
2014-15 as per MERC.
Annual Energy Yield: There are number of factors(e.g. Air
pollution, Shading, Soiling, Ambient temperature, Downtime
etc.) Which affect annual yield of Solar PV.
For 1 MWp Plant annual yield would averaged around 1.4
million kWh units. Yield prediction are assumed for next 25
years.
Certified Emission Reductions: As India is non Annex 1 party
under UN Clean Development Mechanism (CDM) qualifying
solar projects could generate Certified Emission
Reductions(CERs)
22. Energy Price :
Solar PV Plant under REC mechanism can earn its revenue from selling grey.
In the financial model it is assumed that grey component of energy sold to
State discom at MSEDCL.
Operation and Maintenance cost: One of the major benefit of Solar PV plant is
less O & M cost as compared to other renewable energy technologies.
Financing Assumptions: General financial assumptions for a project in India
as follows
Financial Structure: Equity 30 % and debt 70 % as assumed in MERC tariff
order.
Debt repayment is taken over as 10 years. Interest rate on term loan and work
capital is taken as 12.87% and 13.37% respectively.
23. Floating solar PV Indian Context
Great potential for floating PV.
Availability of water bodies and land issues are main
accelerators for floating PV solar Panels.
Increased efficiency of Floating PV over Land PV
installed will attract more investment due to better
returns.
Availability of trained manpower and Govt. Policies
have boosts the confidence of investors.
Stable floating PV platforms results in minimum
operation & maintenance cost.
