Floating Solar Photovoltaic (FSPV): A Third Pillar to Solar PV Sector?Executive Summary9
Floating Solar Photovoltaic (FSPV): A Third Pillar to Solar PV Sector?India has done a remarkable job in terms of deploymentof renewable energy-based installations, growing almost3.5 folds in the last 5–6 years, with most of the capacitycoming from onshore wind and solar photovoltaic (PV)based installations. At present India’s grid-connectedsolar PV sector is majorly dominated by the ground-basedinstallations (93%1) while the balance is contributed byrooftop the based solar PV installations. The installationcost of utility-scale solar PV in the country has declined by84%2 between 2010-2018, making India world’s topmostcountry in achieving the lowest installation cost for utilityscale solar PV. It is well know that solar PV deploymentis quite land intensive and scaling up the project sizesrequires large chunk of contiguous land parcels, whichbecomes challenging in many situations. In order to keeppace of development commensurate with the nationaltargets for solar capacity additions, alternatives arerequired to be explored and established. Floating solar PV(FSPV) or floatovoltaics is one such alternative, which hasstarted getting traction worldwide and is expected to growstrongly over the coming years. It is estimated that theannual capacity addition may rise from the current installedof 1.314 GWp in 2018 to 4.6 GWp by 2022. Presently, Chinais the leading international market followed by Japan andSouth Korea. India also has very bright prospects to developFSPV projects due to availability of large water bodies.As a technology, FSPV is in a very early stage of developmentin India. Till now, only a few projects with cumulativecapacity of 2.7 MW have been installed. However, over 1.7GW capacity projects are reported to be in various stagesof development. FSPV market appears to inch forward tomake its presence felt in India and the tariffs discoveredthrough bids have already shown rapid reductions. So farlarge-to-medium size man-made inland waterbodies seemsto have attracted initial interest to install FSPV based powerplants, but all these waterbodies were created to servevarious purposes like – irrigation, water supply, fishing,hydroelectric, navigation, etc., and this warrants greatdeal of diligence to balance out various usages o

Development of Floating Photovoltaic System(14) discusses issues related to site selection for FSPV. In this paper, property survey, on-site survey, and photovoltaic resource survey were conducted with the case of 100 kW tracking-type floating photovoltaic system in Hapcheon Dam.

The 100GW Solar Power (by year 2022) target set by Govt. of India needs optimum utilisation of available area for deployment of Solar PV panels. Though land & roof tops are considered as focus areas, Floating Solar PV (FSPV) on large reservoirs & other water bodies also offers significant potential.
Solar energy involves the use of the sun's free energy to provide electricity using solar photovoltaic panels (PV). Solar PV requires only daylight and not direct sunlight to generate electricity. As such, power can be generated even on a cloudy day. What is a solar photovoltaic panel? Solar photovoltaic systems comprise two main components
A new era in solar power i.e., floating solar power plants will solve this issue. This floating solar plant can be installed in any water bodies which will not onlydecrease the cost of the land but also will raise the amount of generation with the cooling effect of water. This paper presents the technical details of floating solar power plants.
