Renewable energy sources have a renewable and sustainable nature and the utilization of renewable energy sources is an alternative energy that needs to be developed further. In this research, a Characteristics Study of Temperature Changes on Photovoltaic Surfaces against the Quality of Output Current in Solar Power Plants are measured, and it is known that the optimum current value is at 1.92 Ampere, the optimum temperature is at 37.4 °C, and the highest exchange rate is at 2.08 Ampere while the temperature on the surface of the solar cell is at 37.4 °C. In accordance with the results, which have been done by using a mathematical regression equation that is the statistical equation quadratic regression, it can be known that the characteristics of solar cells have an efficient workforce is around 37.4 °C.
