Abstract
The world market of generated power plants is more and more filled with renewable energy installations and Kazakhstan is also not lagging behind in this direction. In our country, projects for the construction of large, industrial solar power plants are being rapidly implemented. To ensure the proper functioning of solar power plants and preventive detection of problems, it is advisable to calculate certain indicators to assess the efficiency of the functioning of the stations. The purpose of this work is to assess the efficiency of the operation of an industrial solar power plant (SPP) with a capacity of 40 MW. The internationally accepted standards for calculating the efficiency of the functioning of photovoltaic installations are considered, the assessment method is chosen - the calculation of the coefficient of the efficiency of the functioning of SES - Performance Ratio (PR). Collected data on the amount of solar radiation, electricity supply to the grid for the period January - February 2020, based on the data, PR calculations were carried out, the results were analyzed.
