The tending extinction of fossil fuels has already created an awareness to look for alternative sources of energy of which solar is most promising in a topical country like ours , where it is available in abundance . The efforts are being made to utilize solar energy in building sector to fulfill the thermal as well as electrical requirements. Various thermal systems have being developed and commercialized for space and water heating . Work is being done on projects to generate electricity through photovoltaic convert ion. The efficiency of the photovoltaic conversion is inversely proportional to the temperature.
When the temperature rises, there are occasions when the PV conversion is very adversely affected leading to the system failure. The basic idea in the development of hybrid panel is to utilize the radiations not used for photovoltaic conversion, directly for thermal purposes and all radiations falling on the photovoltaic cell, which are partially used for PV conversion and the remaining heats up the cells. A suitable heat exchanger has been designed & attached to the photovoltaic panel to extract the heat from hybrid panel to give
Hot water for use in buildings
Increased PV efficiency.
This paper deals with the results obtained from glass to glass-laminated ONGC type PV module and the initial performance evaluation test of modified module along with its instrumentation.
