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.

12. STATE WISE INSTALLED CAPACITY
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.

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.

18. Maharashtra Model Solar Policy
Financial outlay of Subsidy Scheme

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.
