In this article, a project of portable photoelectric and photo thermal devices with a power of 60W based on crystalline silicon photoelectric batteries for the production and use of electricity and hot water for household needs in the rural areas of the republic was created. This natural experiment served two purposes. The first is to determine the optimal type for the climate when the various types of PVs available in the local commercial market are used in hot climates. Second, the results of determining and comparing the changes in parameters and energy efficiency of PV and PVT with the same base and capacity at the same time under the same conditions are presented. The results of the study of the parameters that increase their effectiveness have been considered. Special attention is paid to modern components and equipment so that these devices are relatively compact and convenient to operate and control occurs easily.
