High magnitudes of temperature are maintained at excess energy sections by conversion of difference of generated energy and consumed energy into heat. In case of reduction of generated energy in the course of changing the orientation of solar batteries on Sun, temperature in these zones is reduced to low limits at simultaneous equality of energies. In case of further increase of generated energy, temperature in said zones is increased to high limits at equality of energies. Then, in the course of change of generated energy, temperature correction cycles in temperature control zones are repeated.
EFFECT: avoidance of excess of consumed energy above generated energy of solar batteries.
