An approach on mathematical modeling of photovoltaic solar panels

In this paper we propose three mathematical models for photovoltaic solar panels. The mathematical modeling of photovoltaic solar panels (PVSP) is essential in the analysis of solar power systems operation. The simulations can predict the performance of different configurations of solar energy conversion systems in power, and allow the choice of the technically and economically optimal variants. Mathematical modeling is essential in determining a function voltage - current, approaching the most of high experimental feature. The three mathematical models based on sine and cosine functions are considered by the authors as the closest to the experimental external characteristics.
