Abstract: This paper establishes a mathematical model based on the calculation method of the average irradiance of the inclined surface proposed by Klein and Theilacker, and uses computer language programming to complete the software implementation of the algorithm. It can calculate the irradiance of the array surface in some areas of our country, the optimal inclination angle of the whole year, and the optimal inclination angle in different time periods. The comparison with previous research results and mature software results shows that the calculation method has a good applicability. This paper proposes a method of optimizing the method for division of seasons, , adjusting the period of inclination angle change, which can further increase the annual radiation of the array surface, and provide a new idea for the improvement of photovoltaic system design.

Keywords: solar array; optimal inclination angle; solar radiation; system improvement
