RESEARCH EFFICIENCY ELECTRIC ENERGY EXTRACTION METHODS OF PHOTOVOLTAIC INSTALLATIONS OPERATING UNDER PARTIAL SHADOWING
The article deals with research in solar power plants and, Renewable Energy Laboratory, working in conditions of non-uniform illumination, with different methods of selection.Performance characteristics via implementing various methods of energy choice, to assess their effectiveness, depending on the nature of shadowing. It is shown experimentally that the use of "Intelligent maximum power selection device", possibly increasing the capacity of the parallel groups to several times during partial shading more than 2 out of 18 panels. The results of the research can be used in the design of new photovoltaic plants and modernization of existing ones.
