Design of Solar Tracker on Solar Panel with Fresnel Concentrator
Indonesia is a country with a tropical climate that has a solar energy potential of 4.8 kWh/m2. So it can be used as an alternative power plant using solar panels. Although the potential of solar energy cannot be used fully because the efficiency of solar panels is still low> Therefore, this study aims to improve the power output of solar panel systems with solar tracker and Fresnel lens concentrator. The use of solar trackers and Fresnel lens concentrator can increase the intensity of solar radiation in solar panel systems. This study conducted for eleven days using a 10WP solar panel. By comparison of the solar panel area with the Fresnel 1: 1.94 lens area, we get the result of an increase in power from the solar tracker design on the solar panel with a Fresnel lens concentrator of 76.85% to 82.52%.
