건물통합형 PV Solar Roof의 통풍효과 실험분석

Abstract

The integration of PV modules into building facades or roof could raise PV module temperature that results in the reduction of electrical power generation. Lowering operating temperature of PV module is important in this respect, and PV module temperature should be considered more accurately, for building-integrated PV(BIPV) systems in predicting their performance. This paper describes a BIPV solar roof design and verifies its performance through experiment in relation to the effect of ventilation in space between PV module and roof surface. The results showed that the ventilation in the space had a positive effect in lowering the module temperature of the BIPV solar roof that enhanced the performance of its electricity generation.Keywards : 건물통합형 PV solar roof(building-integrated photovoltaic solar roof), PV모듈온도(PV module temperature), 통풍효과(ventilation effect), 전력생산량(generated electricity)
