| Description
| - At present with continuously increasing number of installations of renewable sources in residential sector and with purchase price lowering, the most efficient utilization of such produced energy will be required. In this paper I present one of possible solutions based on increasing of efficiency of photovoltaic (PV) cell by cooling its surface by heat pump. Assumption of increasing efficiency comes from specific characteristics of PV cell materials. For optimal operation of photovoltaic module we need to calculate the amount of thermal energy converted by solar cell from incoming solar light. This amount has to be di-verted off the surface of PV cell by heat pump. However, this heat serves only as a additional source for heat pump. Output power of heat pump can be projected on calculation of thermal energy demand for considered building. For this calculation I used the most common method for heat transmission through external walls of the building. For visualization of annual heat demand and for rough estimation of thermal energy produced by PV module I performed these calculations with average temperature and solar irradiance on m2. I obtained this data from a meteorological station located in Plzeň ? Borská pole. The main problem of heat pump cooperation with PV mod-ule is in different time distribution of heat demand and maximal production of electricity. Maximal solar irradiance on surface of PV module occurs during the longest days in summer months, while thermal losses of heated building are very small in this period. Surplus thermal energy could be used for heating of domestic water. Also thermal energy storage comes into question.
