Abstract:

Photovoltaic panels (solar cells), they receive photon energy from sunlight, convert them to electrical energy by the semiconductor structural features. Photovoltaic panels produce a voltage, depending on the change of functional sunlight exposure. Produced voltage and determining of provided electrical power, must be dealt with the physical parameters that uses the concepts of light and temperature. In this study, usage of monocrystalline and polycrystalline structured photovoltaic panels electrical energy conversion for different atmospheric temperature and different sunlight intensity are studied. With the realization of the applications, photovoltaic panels' thermal change effects 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, the obtained principles of functional changes are interpreted.
