태양전지의 환경요소변화에따른 출력특성

Abstract

The research for a substitute for fossil energy sources and the worldwide improving environmental awareness have increased the interest in PV system as inexhaustible, environmentally friendly energy technology. Photovoltaic system is using the clean and infinite energy source, there is no air pollution, noise and vibration. PV system operate without fuel convoy, rotation surface, high temperature and high pressure, So it is easy to maintenance, long life cycle, simple installation. Respectively international and domestic PV market growth over 30% every year. Photovoltaic power systems convert sunlight directly into electricity. A residential PV power system enables a homeowner to generate some or all of their daily electrical energy demand on their own roof, exchanging daytime excess power for future energy needs. While compare preexisted generation of electric power method with PV system, PV system is more expensive, lower solar energy density, convert efficiency and depend on the weather and natural environment. This paper presents the performance a solar generation simulator while integrating research results. This solar generation simulator different with the existing one, allows the experiment of everyday generation capacity according to the variation of solar radiation amount and the acquisition of characteristics according to the variation of installation angle. It is expected that this solar generation simulator could be used of the 10kW photovoltaic generation system, which largely varies with a installation place and the application products.
