Studi Eksperimental Pendingin Panel Surya dengan Sistem Pendingin Pasif

Abstrak

Solar energy, as one of the most abundant renewable energy sources, has gained significant attention. However, one of the primary challenges faced by solar panel technology is the decrease in efficiency due to rising operational temperatures. The purpose of this research is to determine the effect of a passive cooling system using fabric wicks on solar panel performance through the principle of capillarity. The testing method was conducted by comparing solar panels with and without a cooling system. Parameters measured included solar radiation intensity (IG), panel temperature (T), open-circuit voltage (Voc), and short-circuit current (Isc), from 07:30 WITA to 16:30. The results of this study indicated that the use of a passive cooling system on solar panels helps lower the panel's surface temperature. At its peak at 12:00 WITA, the TPVC (cooled panel temperature) reached 52.4°C in September and 49.1°C in October, while the TPV-nc (non-cooled panel temperature) reached 57.6°C in September and 54.7°C in October. This improved PV performance, with ηPVc (efficiency of cooled panel) reaching 23% in September at 08:00 WITA and 26% in September at 17:00 WITA, whereas ηPV-nc (efficiency of non-cooled panel) reached 18% in September and 19% in October. This research proves effective in enhancing the thermal and electrical performance of PV systems using passive cooling without requiring additional energy consumption, increasing efficiency by 3% to 5%.
