Firstgreen solar project review: Solar Power Project by Reliance
Reliance Power Limited has installed a 40-megawatt (MW) solar photovoltaic power generation plant near the village of Dhursar in Jaisalmer district of Rajasthan state. The annual global horizontal irradiance at the project site is estimated to be 2,064 kilowatt-hours (kWh) per square meter, one of the highest in the country.
The project has used fixed-tilt cadmium telluride thin film solar photovoltaic modules. Cadmium telluride technology is suited to warm and dry environment such as Rajasthan where ambient air temperatures can exceed 40C in summer, which can reduce the net energy yield of the modules. The solar photovoltaic modules have a projected degradation of 1.0% per year for the first 10 years of operation and 0.6% per year for the next 15 years of operations.
The electricity generated from the project will be evacuated from the project site to the existing 220-kilovolt (kV) Dechu substation of Rajasthan Vidyut Prasaran Nigam Limited (RVPNL) through a 30 km long, 220 kV double-circuit transmission line to be built by DSPPL.
The project is estimated to cost $147.5 million, and financed by ADB.
