100 kWp grid tied rooftop system installed at Delhi Public School, Varanasi

KOR Energy (India) Pvt. Ltd, has successfully installed a 100 kWp grid tied rooftop solar system at Delhi Public School (DPS), Varanasi. The project has a power generation capacity of 145,000 units/year and is the National Solar Mission.
Sushil Kumar Sarawgi, Director, KOR Energy (India) Pvt. Ltd said, “We understand that solar is the need of the hour, and our vision is to help India go green by empowering establishments through renewable technologies. The system installed at DPS will produce approximately 12,000 units of electricity resulting in savings of Rs 85,000 per month, thus, making it cost effective.”
The system will have an additional benefit of net metering, giving credit in electricity bill against the excess generated during off peak hours and school holidays. The payback period can thus be achieved in four-five years, and the performance warranty is 25 years.
DPS will receive from SECI under government scheme, subsidy of 30 per cent on project cost solar for schools, colleges and other non-profit trusts and societies. Due to provision of accelerated depreciation on commercial establishment, DPS will get major tax relief in the upfront cost of solar plant. The institution will be saving nearly Rs 2.5 crore in solar panel investment over lifetime of the project.
KOR Energy has used Polycrystalline Modules of 315 Wp manufactured by Vikram Solar and solar string inverters from ABB Group have been utilised for the system. It also has remote monitoring of production that offers accurate fault recognition and real time performance monitoring.
