UJI KINERJA PANEL SURYA SILIKON TIPE POLIKRISTAL DAN MONOKRISTAL

The objective of this research was to study the performance of polycrystalline and monocrystalline silicon solar cells on some angles of tilt. The research was conducted at the Laboratory of Energy, Department of Agricultural Technology, Faculty of Agriculture, Sriwijaya University Indralaya, started on January to December 2016. The research consisted of two phases: preparation and polycrystalline and monocrystalline silicon solar panels circuit assembly; and circuit testing. The esearch used polycrystalline and monocrystaline silicon solar panel with variation of tilt angle 0o, 10o, 20o, and 30o. Parameters observed were solar panel power, solar panel efficiency, and intensity of sunlight. The results showed that monocrystalline silicon solar panel produced better performance (high power) at solar irradiance in range between 209.35 and 1437.8 W/m2; and polycrystalline silicon solar panel produced better performance at solar irradiance in range between 0.32 and 193.5 W/m2 at various tilt angles. Polycrystalline and monocrystalline silicon solar panels produced the highest power at 30o angle on second day at 12.00 p.m with the highest solar irradiance was 1413,31 W/m2 for polycrystalline was 63.91 Watt and monocrystalline was 72.54 Watt. The highest efficiency produced by silicon solar panel was at 20o angle for polycrystalline was 15.69 % and for monocrystalline was 19.63 %. So, monocrystalline silicon solar panel produced better performance than polycrystalline in areas with high solar irradiance.
