ШЛЯХИ ПІДВИЩЕННЯ ЕФЕКТИВНОСТІ Й ТЕРМІНУ ЕКСПЛУАТАЦІЇ ФОТОЕЛЕКТРИЧНИХ МОДУЛІВ І ФОТОЕЛЕКТРИЧНИХ СТАНЦІЙ

Each complex power system, which can also include photovoltaic plants (PVP), during the entire period of operation, from construction  to its completion, are exposed to various factors and factors that affect the service life of the station and and the effectiveness of its work. Reduced efficiency (efficiency) and reduced service life of photovoltaic plants depends on the influence of climatic conditions (fluctuations in ambient temperature, precipitation etc.) in the area of the station, on irreversible physical processes occurring in the structural elements of the PVP and its main components, the quality of manufacture individual components of the station, from the human factor – the negative effects of unqualified service personnel. Some of the above factors influencing the work of PVP can be combined into a separate group under the general term – aging, or as –degradation. The greatest temporal degradation affects the main component of each PVP– photovoltaic modules (PVM). The authors of this publication aim to identify, systematize by various criteria and investigate the most common and typical types of degradation of PVM, which usually occur, with analysis and theoretical justification of their causes, consequences and ways to overcome or prevent. In addition, the paper offers options for solving certain problems of certain types of failure of photovoltaic modules by changing and improving circuit and design solutions for the design of photovoltaic stations and also options for refining photovoltaic modules that are part of photovoltaic stations. The proposed solutions will increase the efficiency and reliability of photovoltaic modules and photovoltaic stations in general. Ref. 10,fig. 5.
