3. What is floating solar PV?
UNDER STANDING SOLAR PV

4. It is a technique of installing PV on water
bodies instead of conventional place like land
or rooftops.

5. NEED FOR FLOATING PV
• Solar photovoltaic (PV) installation has the burden of
intense land requirements, installing solar PV on water
bodies can resolve this issue.

6. COMPONENTS OF PV
SYSTEM
• PONTOON
• FLOATS
• MOORING SYSTEM
• SOLAR PV MODULE
• CABLES AND CONNECTORS
• FLOATING STRUCTURE

7. PONTOON:
A pontoon is flotation device with buoyancy enough to float
by itself as well as with a heavy load.
FLOATS:
Multiple plastic hollow floats with effective buoyancy to
self weight ratio are combined over and over again,
forming a giant pontoon.

8. MOORING SYSTEM:
A mooring system is an permanent structure which keeps
the floating panels on same position and prevent them
from turning or floating away.
Usually mooring system platforms can be done by using
nylon rope slings.

9. SOLAR PV MODULE:
Standard polycrystalline solar PV modules have
been used for the floating solar systems.
In salty water bodies “Standard Aluminium Frames
and Mounts” are proposed due to fast degradation
of metals on salty water.

10. CABLES AND CONNECTORS:
• Electricity is drawn from the solar array and transported
to the land.
• the power can be fed to the grid or stored in batteries
• High temperature resistance, water proof and robust
cables are to be used to provide a long service

11. FLOATING STRUCTURE
 FTCC:
• The system consists of a raft
supporting standard photovoltaic
panels
• The Floating Tracker Cooling
Concentrator (FTCC) uses reflectors
to increase the efficiency .
• The FTCC also uses water to help
stay cool, reduce costs to about 20%
less than conventional land.
• FTCC is Design in SIT – Italy.
 Submerged photovoltaic solar
panel
• In this configuration the panels are
immersed in water and this allows us
to realize a gain in efficiency in
summers due to cooling effect.
• Designed by Infratech Industries
Inc., Australia.

12. SUNdy concept the hexagonal design
• This design consists of a series of
thin film PV panels connected
together and then onto the
electrical bus lines running
through the hexagonal vertices.
• The panels themselves are
envisaged to be laminated and
adhered to a flexible foam surface,
which gives the panel's buoyancy
and structure
• At the edge of the float is
embedded a marine grade
connector, which allows the
panels to be connected both
mechanically and electrically.

13.  HYDRELIO Floating solar component
• The latest floating structure
are installed at Nishihira
and Higashihira Ponds in
Kato City is the work of
Kyocera Corporation and
Century Tokyo Leasing
Corporation.
• They are designed typhoon-
proof (due to their sturdy,
high-density polyethylene
and array design).

14. PV FLOATING PLANTS OUTLINE

15. ADVANTAGES
1. They reduce reservoir water evaporation and algae growth
by shading the water.
2. Floating platforms are 100% recyclable, utilizing high-
density polyethylene, which can withstand ultraviolet rays
and resists corrosion.
3. Floating solar power generating systems typically
generate more electricity than ground-mount and rooftop
systems due to the cooling effect of the water.
4. The floating platforms are designed and engineered to
withstand extreme physical stress, including typhoon and
storm conditions.
5. More module install compare with the other system.

18. INDIA AND FLOATING PV
• First 10KW floating solar power plant in conceptualized and ingeniously
implemented at RAJARHAT in KOLKATA.
• India is currently making plans to build the world's largest floating solar
power plant.
• The plant is expected to produce 50 MW under NHPC (national
hydroelectric power cooperation).
• This major project is expected to cost between 64 and 72 million dollars.
• It will be set up in bodies of water in the Southern state of Kerala by the
National Hydro Power Corporation with technical assistance from MANIT
Bhopal
