2. Floating Solar Technology – Market Outlook
Gensol Group
The Global Floating Solar Panels Market is expected to reach US$ 842.0 Million by 2023, expanding at a CAGR (Compound Annual Growth
Rate) of 65.1% during the forecast period 2016 to 2023. However, high cost of installation restricts the use of floating solar panels which in
turn is anticipated to hamper the demand for the floating solar panels during the forecast period (2016-2023).

3. Floating Solar Technology Development– Proactive Countries
Gensol Group
• Market target: Countries like Japan,
Singapore, UK (London) and India have
actually limited space to install large
ground mounted PV panels. Several
projects are emerging in these countries;
the biggest one is expected in Japan with
13.7 MWp of installed capacity.
• Customer target: some of these projects
are installed on a hydro plant, typically in
Brazil and Chile.
• Major Market Players
o Ciel & Terre, France;
o Pristine Sun LLC ;
o LG CNS, South Korea;
o Yingli Solar ;
o Sunfloat, Netherlands;
o KYOCERA Corporation etc
Floating solar projects are mostly located in Asia showing high potential for mass floating solar market growth with almost 78% of the
expected worldwide installed capacity. Europe, North and Latin America are still developing pilot farms and expected to be niche
markets for this technology.

4. Floating Solar Technology – An Expedient Alternative
Gensol Group
Floating solar PV power project is an emerging concept which is unfurling both in India and Globally. This can be
established on all types of water bodies like lakes, saltwater lakes, reservoirs, irrigation ponds, dams, rivers etc.
Various advantages of floating solar PV plants over ground
installations:
•Ever increasing power demand & depletion of fossil fuels.
•Leads to shift our focus to renewable energy sources.
•Availability of land – A big concern. Planning to put a floating PV in dam
reservoirs, it can make better use of the reservoir surface, which is anyway
lying idle
•Cooling of Solar panels which makes modules more efficient.
•Tracking - The entire system can easily and cheaply rotate
•Algal bloom - Reduced sunlight penetration lowers the potential for blue-green
algae growth.
•Evaporation - The increased shading reduces evaporation and saves water

5. Advantages of Floating Solar Technology
Gensol Group
No costs related to land acquisition
Effective natural evaporative cooling mechanism for
operational efficiency
Possibility of low cost Azimuthal tracking -
improves plant load factor (PLF)
Low cost civil structure
Provides vast, level, hindrance free surface for
efficient tapping of solar energy
Ability to merge as hatcheries for fish inhabiting the
area and Reduce algae growth
Reduction in trans evaporation- beneficial for large
thermal power plants
Water and energy balance with and without floating solar installations
This concept is innovative because, about 70%
of the earth’s surface is covered with water!

6. Working Methodology – Floating Solar PV
Gensol Group
A majority of the installations utilized a floating pontoon constructed either from fiber- reinforced plastic (FRP), Medium Density
Polyethylene (MDPE) or Ferro cement, high-density thermoplastic (HDPE). The solar PV modules were supported on these pontoons through
the use of metal structures and were inclined in a majority of cases to maximize the solar incidence.

8. Major Components of Floating Solar– Mooring/Anchoring
System
Gensol Group
A mooring refers to any permanent structure to which a floating structure
may be secured. A floating structure is secured to a mooring to forestall
free movement of the floating structure on the water. An anchor mooring
fixes a floating structure’s position relative to a point on the bottom of a
waterway without connecting the floating structure to shore.
Mooring System – (Bottom Anchoring)
The anchoring system design is usually composed of:
•Aluminium spreader bars that enable the connection of the mooring lines to the
island and spread the load through the two connection tabs of the floats.
•Cables to link spreader bars to anchors (sized taking into account water level
variation).
•Chains at the end of the cables to adjust length.
•Main and secondary float rows (without PV panel) to secure buoyancy during harsh
winds.
•Anchors to moor the island on the bottom or on shores in order to withstand wind
loads and to reduce movement of the island on the water surface.

9. Major Components of Floating Solar PV – Pontoon System`
Gensol Group
The entire floating solar mounting system encloses
•HDPE floaters, which have passed Hunt sealability test (CN), aging test, UV test, TUV
wind tunnel test and other tests.
•The tensile strength of floaters (2000 daN) is higher than most similar products.
•The solar modules will be easily installed on main floaters by aluminum alloy
clamps, which save time and labor cost. Its service life reaches 25 years.

• Stainless Bolt kit
A pontoon is flotation structure and has buoyancy enough to float on water
and support a heavy load. The structure is designed such that it can hold
number of panels.

10. Key Design Features of Floating solar PV
Gensol Group
•Material used should be completely non-toxic, resistant to salt water and alkalis acids, UV rays resistant and
completely recyclable.
•It should easily adapt to changes in water level in reservoirs.
•The floating material entailed would be completely recyclable.
•The structures should withstand high temperature variation from -60°C to 80°C.
•Long life time that is 25 years withstand capability under water.
Major Key Design Features of Floating Solar PV are enlisted below:
•Resistant to ultra violet radiation & corrosion: The structures are made of HDPE through blow mold manufacturing
process. Due to their highly resistant composition, it can withstand for more than 20years.
•Extreme wind resistant: HDPE Structures floating solar power can withstand up to 118 m/hr winds
•Safe mounting & maintenance: It has been designed to be easily and quickly deployed. The secondary floats allow
easy access to the panels for maintenance and cleaning.
•Cost-effective: Cost is less per module compared to zinc coated stainless steel structures. The other manufacturing
benefits of HDPE structures are easy to install, i.e. easy to adapt to any electrical configuration.
• Scalable from low to high power generation, no need of heavy equipment for installation of HDPE structures.
Recycling is possible for HDPE materials.

13. Floating Solar PV Project – Case Studies (1/4)
Gensol Group
Australian floating solar innovator Sunengy has completed its first pilot plant
in India on a hydropower storage dam owned by The Tata Power Co Ltd, India’s
largest private utility.
LSA adds solar as a secondary resource and taps directly into the under utilised
transmission grids at hydropower storage dams, with the hydropower turbines
providing full backup for the solar power. This gives tremendous potential to
dramatically increase the energy generation capacity of many of the world’s
hydro facilities without straining additional water resource, or occupying any
land area
Drawbacks -CPV systems are significantly affected by poor air quality, reducing
output up to 40% at certain times. There has also been an unexpected
development in that while observing some of the difficulties with the CPV
system specific to the hazy conditions in India

16. Floating solar PV Project – Case Studies (4/4)
Floating Tracking Cooling Concentrating PV plant
The system consists of a platform with photovoltaic panels supported by a structure in polyethylene tubes. The power of a module ranges from 20
to 500 kW, depending on the dimension of the platform. Cooling of the panel is ensured by a veil of water generated by a set of irrigators located in
the upper part of PV panel. Cables and electrical parts are far from the surface of the water and adequately protected.
1) Reflectors, with vertical axis tracking, increase the annual energy yield.
2) PV panels stay at low temperatures with an average gain of efficiency of more
than 15% yearly
3) The floating platform structure allows an efficient one axis tracking, so that the
system is suitable for positioning reflectors and for increasing radiation on the
panels.
4) FTCC exploits the unused areas of artificial basins and has a very limited visual
impact.
