Solar cells are made of material silicon which generally has properties as an excellent absorber of solar radiation energy, as long as the solar panel operates under the sun the solar radiation energy will always be converted into electrical energy by solar cells, but solar cells will also experience heat and will effect on the panel output voltage. The voltage and electric current generated by solar panels are influenced by the intensity of solar radiation and ambient temperature. This study aims to determine changes in temperature to the intensity of sunlight that can be seen in the data logger. The Effect of panel temperature on the power generated in the measurement of the data logger and the results of data regression analysis show that as the panel temperature increases, the power generated also increases linearly. On the first day the power increase was 1.0463T, on the second day the power increase was 1.2614T, and the third day the power increase was 1.2901T. As for the effect of the intensity of sunlight on the power generated from the results of data regression analysis, the increase in the intensity of sunlight, the power generated increases linearly. On the first day the power increase was 0.0368IT, on the second day the power increase was 0.0416IT, and on the third day the power increase was 0.0441IT.
