Abstract

Solar energy is used as a potential alternative energy source, especially seen from the source that emits energy in very large quantities and takes a long time. Solar energy is converted into electrical energy using solar panels. The performance of the solar panel depends on the surface temperature of the panel because the semi-conductor material in the panel is very sensitive to temperature changes. This study aims to determine the effect of cooling below the surface of the solar panel on the performance produced by the solar panel by varying the type of cooler. The type of cooler used is a blower and a fan. To get a comparison of the data, the author uses a single panel without using a cooler. The total solar panels used are 3 monocrystallin 180 WP solar panels. The tools used in this research are anemometer, pyranometer, thermometer couple, clamp meter and multimeter. From the research conducted, it was found that the solar panel without cooling has an average efficiency value of 17.65 % and the heat transfer rate is 0 W. Solar panels with blower cooling variations have an average efficiency value of 18.42 % and the heat transfer rate is 20.1 W. Solar panels with fan cooling variations have an average efficiency value of 18.95 % and the heat transfer rate is 33.97 W. There is an effect of the cooling carried out on the lower surface of the solar panels based on the cooling variation and increasing the rate of heat transfer which had an impact on the performance of the solar panels. The best efficiency values occur in solar panels whose coolant variations have high wind speeds.
