Our invention addresses the paradox of ‘scarcity amidst plenty’ with respect to high solar PV electricity penetration in India. This problem is multi faceted that delves into:
this segment consists of both Hydro-power projects as well as irrigation dams. FSPV power plant would not only judiciously utilise the available but underutilized surface area of these reservoirs, but will also generate electricity while reigning in evaporation losses. In addition to providing enhanced energy generation. India, according to CWC, has close to 5000 reservoirs, which impound a huge quantum of water by volume and create a currently unutilized surface area of 38,000 Sq. km. A mere 20% of this surface area, if utilized in an environmentally benign manner can create a capacity of 750 GW – which is approximately double our current capacity. This can be done without acquiring even an inch of land, which, in our long-term interest can be left for more productive uses – agriculture and forests.
Industries with large water requirements such as thermal power plants
they have large raw water reservoirs, which can be utilized for FSPV power plants. This would cut down their revenue losses from evaporation and provide clean power for ancillary requirements. India’s already established capacity of 293 GW of thermal power can easily accommodate approximately 5 GW of solar over the underutilized but readily available blue
Water bodies in Urban areas
We, in India, lose existing water bodies to pressures of urbanization. The story repeats itself in our metropolises –Bangalore, Delhi, Chennai, inter alia – as well as tier I and tier II cities. An FSPV power plant may help in conservation efforts of these water bodies while providing clean energy and thus opening doors to concomitant technologies, which can breathe new life into our dying water bodies. How much we work
towards creating these emancipatory spaces depend on our political will or the lack of it.
Chandigarh Renewable Energy and Science & Technology Promotion Society
Design Manufacture Supply Erection Testing and Commissioning of 10 kWp Floating SPV Solar Power Plant with Fountain and 5 years CMC at Dhanas Lake Chandigarh
The project is amongst the first pilot project of Floating Solar PV (FSPV) in India, and is considered a benchmark for future project in the country. The proposed power plant is a floating structure adaptable for water-based operation that holds multiple arrays of solar photovoltaic modules. The structure is rotatable to optimize the angular orientation thereof relative to the position of the sun. More particularly, the floating structure uses a platform that includes a large outer ring that floats on water, and a modular hierarchical hexagonal honeycomb grid supporting a plurality of rows of mounting structure which house the solar photovoltaic modules. A series of motors attached to each array of solar photovoltaic panels regulates the vertical position of the panels such that the tilt of the panel is equivalent to the altitude angle of the sun, while a propulsion system fitted onto the hexagonal honeycomb grid is responsible for keeping the panels in line with the direction of the sun.
Indian Oil Corporation Limited (IOCL)
Design, Engineering Supply, Installation, Testing and Commissioning of Grid-Connected 100 kWp Fixed Tilt Floating (Land-Neutral) Solar PV power Plant
The proposed power plant is a floating structure that supports multiple arrays of Solar PV modules at a fixed tilt.The plant is housed in a raw water reservoir (RWH), located in the Naptha Cracker unit of IOCL. The motivation behind the development of the 100 kWp land-neutral solar PV power plants is threefold, namely [a] avoiding the displacement of land that could be used for expansion of infrastructure in the refinery complex; [b] reduction in evaporation losses from reservoir, a definite positive for the plant; and [c] accumulation of benefits from additional energy yield, largely due to the result of cooling (of solar PV modules) from water, consistent with the negative temperature coefficient performance for PV modules. The aforementioned project is a demonstration project that would pave the way for up-scaling of such plants in the IOCL complexes located in various parts of the country. FSPV is extremely beneficial for industries with large water requirements such as thermal power plants, refineries etc.
