Hybrid solar panel for generation of electricity through photovoltaic cells and for water heating by driving heat

摘要

Hybrid solar panel for generation of electricity through photovoltaic cells and for heating water for driving the heat "it is a solution that combines the technique of heating water by heat conduction to the electricity generation by cells fotovolta ICAS.The solar radiation incident directly on the solar cells (2) converts the same into electrical energy in the form of voltage and current, continuous (3). Another part is converted into heat by the phenomenon of absorption of radiation by the dark bodies, raising the temperature of the cells, and consequently reducing its efficiency.With the hybrid panel, the heat is transferred to a metal plate with coil (7) which is connected below the solar panel (1), an electric insulating layer of high thermal conductivity (8).The water then, injected from the lower part (5) of the metal plate circulates around a coil (4) remaining in it, by natural convection or forcibly, so as to collect heat from solar cells heated.The water coming out at higher temperature for the upper part of the metal plate (6) can be conveyed to a thermally insulated reservoir for later use, and photovoltaic cells with reduced temperature, then begin to operate with greater efficiency.
