The effects of heat on the solar energy collectors and their productivity

Photovoltaic panels (solar cells), they receive real photon energy from sunlight, convert to electrical energy by the semiconductor structural features. Photovoltaic panels produce an emk, in a change of functional depending on exposed to severity of sunlight. Produced emk or rather determine of providing electrical power, it should be dealt with the physical parameters that used in the concepts of light and temperature. In this study, usage of photovoltaic panels of monocrystalline and polycrystallineon structured, for different atmospheric temperature and different sunlight intensity, electrical energy conversions are studied. With the realization of the applications, thermal change of photovoltaic panels effect upon the energy production is discussed. With the conclusions obtained from the research applications and analyses, for heat exchange in photovoltaic panels to effects upon energy production, they were obtained principles of functional changes and they were interpreted.
