Solar Photovoltaic Thermal (PVT) Cogeneration System

Ref No – TR1076

Snapshot:

The technology harness the waste solar thermal energy and utilizes it to increase efficiency of solar photovoltaic cells , thus increasing the overall net efficiency of the system.

Technology:  

Solar Photovoltaic Thermal energy generation system

 Description:  

Conventional Solar Photovoltaic (PV) panels operate with an efficiency close to 15% under field conditions losing most of the incident solar energy as heat. The key idea of a solar PVT (PV-Thermal) system is to effectively harness this waste heat for cogeneration of electricity and thermal energy using a single system. Solar PVT technology holds significant potential for both residential and industrial customers where rooftop area is a premium. Solar PVT system can be manufactured indigenously contributing to “Make in India” initiative and can play a key role in meeting the National solar energy mission target of 40 GW of rooftop solar and also to satisfy the energy demand of >500 ktoe/annum for low temperature heating applications there by helping in significant reduction of CO2 emissions.

Potential Application:
  • Solar Electricity Production
Benefit / Advantage of Technology:
  • Solar PVT system is anticipated to provide >20% cost savings and >50% roof space savings compared to standalone solar PV and solar thermal systems.
