Abstract

The need for electrical energy is increasing along with industrial progress. One method used to produce electrical energy is to convert radiation energy from sunlight through solar cells or photovoltaics. Solar cells function as a tool to convert sunlight into electrical energy. Pekanbaru, a city in Indonesia, has a high environmental temperature, ranging from 25° to 35° Celsius. Because these temperatures can affect the performance of solar panels, cooling steps are needed so that the resulting output power remains optimal. To overcome this problem, research was conducted to determine the effect of the cooling system on solar panels on their performance. The aim of this research is to determine the effect of the cooling system on solar panels on the performance of 180 Wp monocrystalline solar panels. The tools used during the research were anemometer, pyranometer, thermometer couple, clamp meter and multimeter. This research was carried out by testing the duration of the cooling media flow time. From the research results, it can be seen that the duration of the cooling media flow affects the performance of solar panels. This is because the temperature of the solar panels decreases due to the cooling system using varying time durations. From the research results, variations in time duration have the most influence on the performance of solar panels, namely the time duration of 30 minutes. The duration of the cooling media flowing time affects the performance of the solar panels, where the longer the cooling media flowing time, the better the performance of the solar panels produced, as well as the solar panel parameter values. The performance of the solar panels with the highest parameter values is that at a running time duration of 30 minutes, the highest parameter values are obtained. Open voltage (voc) 40.8 (W), short circuit current (isc) 6.1 (A), maximum power value ( Pmax) 36.86 (W), fill factor 0.887, power output value (Pout) 220.75 (W), and efficiency value 22.1%.
