태양에너지를 이용한 열-전기 동시생산을 위한 PV-Solarwall 단위모듈 성능평가 연구

Abstract

The PV-Solarwall system has been introduced as a promising alternative to harness solar energy for both heating applications and electricity generation simultaneously. The system comprises a PV solar panel(for electricity generation). In addition, the solarwall incorporates a fan strategically located behind the PV panel to bring the warm and fresh air from the solarwall into the room. Because of its location and convective cooling principle, the fan also serves to reduce the operating temperature of the PV panel thereby increasing its efficiency. So this PV-Solarwall system holds much promise for saving heating and electricity costs compared with a PV system without solarwall. In particular, by controlling the tilt angle of the entire PV-Solarwall system between 0˚(horizontal) and 90˚(vertical), the performance of the system can be further evaluated. It is expected that the range of tilt angle PV-Solarwall between 40˚ and 50˚ will improve the output of the system.
