Analysis and Evaluation of Photovoltaic Cell Defects and Their Impact on Electricity Generation

Renewable sources are currently a widely used source of electricity. They are also supported within the European Union. Defects in photovoltaic panels often occur during the implementation and operation of photovoltaic panels. Not all defects can be seen. In practice, it happens that no attention is paid to defects that occur during the operation of the photovoltaic power plant. These defects cause a decrease in electricity production, which reduces the efficiency of this renewable source. This paper describes defects that occur during the implementation and operation of a photovoltaic panel. Based on the performed simulations, the authors describe how defects affect the performance of the photovoltaic panel. Simulations were focused on changing parallel and serial resistance in the simulation model. Results describe the effect changing of serial and parallel resistance to production of electricity from the photovoltaic panels. (Abstract)
