Abstract
Indonesia, being a tropical country, has a high photovoltaic (PV) energy generation potential that can help meet demand due to impending shortage 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 a result of the influence of clouds, but the influence of these clouds causes a lack of uniform illumination of sunlight received by the photovoltaic. This is condition called Partial Shaded. Partially shaded PV systems cannot operate at maximum efficiency because of shadows cast by surrounding structures, foliage and cloud cover. This paper describes an experiment on PV output for the irregularity of sun irradiation. Characteristics of I-V can be influenced by partial 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
