Abstract
This paper considers the thermo physical principles of cogeneration technology with the use of silicon photocells working with a low concentration of solar radiation. The efficiency of the technology is enhanced by the use of photocells at a relatively high temperature and cooling with liquid, which makes it possible to obtain high-potential heat and transmit it to the heat carrier in counter flow mode of the coolant. Transportation of heat energy to a stationary storage system is realized under the influence of the pressure head formed by the temperature gradient along the height of the circulation circuit. A mathematical model is proposed for calculating the thermal energy of linear photovoltaic modules, taking into account the experimentally determined electric efficiency of commercially available silicon photocells.
