태양광자동차의 발전모듈 온도 특성에 따른 최적 설계 기술

Solar cars combine technologies typically used in the alternative energy and automotive industries. The design of a solar vehicle is severely limited by the amount of supplied solar energy input into the car. Currently, most solar cars have been built for the purpose of solar car racing or prototyping of solar energy usage. But in the present study, solar car designed with given solar cells was investigated in terms of daily irradiation, cell temperature and geometrical characteristics to improve the solar power generation and the driving efficiency. Mainly driving power of solar car depends on the performance of photovoltaic cells to convert sunlight into electricity. Unlike solar thermal energy which converts solar energy to heat for either household purposes, industrial purposes or to be converted to electricity, PV cells directly convert sunlight into electricity. Present solar car system``s power output was affected by module inclination and module temperature. Intensity of solar irradiation depending on time was also severely depending on the position of sun. Decreasing cell temperature leads to increase power generation.
