24.198 MW SPV Power Plants installed on Rooftops of Government Institutions / Buildings and Private Sector
REST is executing Rooftop Solar SPV programme in UT Chandigarh under Model Solar City programme of MNRE, (GOI). Taking the initiative further Chandigarh Renewal Energy Science & Technology Promotion Society (CREST) together with Deutsche Gesellschaft für Internationale Zusammenarbeit - German Development Cooperation (GIZ India) have implemented an innovative Photovoltaic Thermal (PVT) technology project of 20kW(Electrical)/48kW (Thermal)at the rooftop of Government Multi Speciality Hospital, Sector 16, Chandigarh. Debendra Dalai, Director Science & Technology & Renewable Energy- cum – CEO, CREST and G Dewan, Director Health & Family Welfare inaugurated the project.
This PVT system is expected to provide two times more energy yield – combining electrical and thermal, as compared to the energy yield from a Photo Voltaic system only. A PVT panel is a hybrid of the “standard” photovoltaic (PV) module and a “polymer absorber” in a single panel producing both power and heat. This configuration is expected to lower the temperature of PV cells thus increasing the electrical efficiency by around 10-12 per cent. While the waste heat is captured and transferred to a fluid (hot water) at estimated 30-40 per cent efficiency providing fluid temperature of 50-80°C. This results in much higher yields from the same area of a standard PV module.
The module technology is a promising option for applications with limited rooftop space with stable demand for both hot water and electricity.
The system is installed on cost-sharing basis, where GIZ has provided the PVT modules while the procurement of balance of system, installation and maintenance is carried out by CREST. The system is grid-connected and capable of serving the annual hot water requirement of two operation theatres. This innovative PVT rooftop project is supported by German Federal Ministry of Economic Cooperation and Development and implemented by GIZ India in cooperation with the Ministry of New and Renewable Energy (MNRE).The system is the 2nd Project of its kind in the country.
