Influence of shading to the output power of photovoltaic in Indonesia

Abstract

Indonesia, being a tropical country, has a high photovoltaic (PV) energy generation potential that can help meet demand due to the impending shortage of power supplies in the coming years. The shading effect is a negative effect that causes the Photovoltaic power output to drop from its normal state. The performance of Photovoltaic Panels (PV) is a shared module surface exposed to sunlight. Shading effects usually occur from the influence of clouds, but the influence of these clouds often causes a lack of uniform illumination of sunlight received by the photovoltaic. This is also often called Partial Shaded. Partially shaded PV systems cannot operate at maximum efficiency because of shadows cast by surrounding structures, foliage and cloud cover. This is done to see the effect of partial shading pattern effect on solar cell PV. Characteristics of I-V can be influenced by pattern shading effect. The voltage and current of PV solar cells will drop from partial shading effect experiment which consists of 20%, 40%, 60%, 80% and 100% shading area.
