Wide use of solar batteries leads to intensive elaboration of technology for manufacturing them as well as their performance. One way to increase the performance of the considered batteries is by decreasing the removal of heat, which was generated during their functioning. In this paper, we consider convective removal of the considered heat. We estimate the intensity of the convective heat removal generated during the functioning of the solar batteries. We consider an analytical approach for analyzing of transfer of the considered heat. The approach gives a possibility to take into account spatial and temporal dependences of heat transport as well as the nonlinearity of the process. We also consider the possibility to control of the considered heat transport.
