Floating Solar Power Plant Training Course
Why Floating Solar Power Power Plant: Solar energy power plant which utilizes the sun’s energy needs adequate space for installation. It is a well-known fact that out of the 510 million Km2surface area of earth, a mere (appx.) 29% is covered with land. Additionally (at some locations) the land may be of importance and it may not be feasible to dedicate (some) space for solar energy power plant. In a country where cities are dense and agricultural land is limited, installing solar power plant (which require huge swathes of land) may not be viable. This is where floating PV power plant can come to our rescue.Floating PV power plant as the name suggests are floating bodies of solar PV plants on water
Requirement to Implement A Floating Solar power Plant :- Floating structure: Also known as Pontoon, the floating structure is a sturdy structure which easily holds the solar panel. It also has enough buoyancy to stay afloat on water while supporting the heavy load.
- Mooring system: The floating structure is held securely with a permeant structure known as mooring. This halts the free movement of the floating structure in water. The floating structure can be fixed with reference to a point on bottom of waterway eliminating the need to connect to the floating structure to the shore. This can be done with help of anchor mooring.
- Under water Cabling: This form as an important link between the grid and the solar panels. Due to its usage under water, the cabling may be designed to be shock and/or leakage proof. A typical technical diagram of floating PV Plant.
Advantages of Floating Solar Power Plant
- Increased output from system: This increase can be attributed to the reduced operating temperature of solar modules resulting from natural cooling from water.
- Savings of water: A cleaning cycle in power plant may happen more than once a week. Such huge quantities of water may be saved if floating PV system is used.
- Alternate source of energy at Dams: The water saved during day time may be utilized during night time to generate more power reducing dependence on fossil fuel based plants Syllabus of Floating Solar Power Plant Design Course
