The Effect of Shading on Performance of Building Integrated Photovoltaic System as Shading Device
초록
영어
Shading is one of the main causes to lower the power generation of PV systems. The shading has to be considered for application of PV system in the built environment. This paper analyzes the effect of shading on the performance of a PV array integrated to a building as a shading device. The building with the PV system is located in Zero Energy Town (ZET) of Korea Institute of Energy Research in South Korea. The methods used for analysis are formula and computer simulations. The result was that the upper PV array made shade onto a lower PV array and the effect of shading mainly occurred during summer season when the sun's altitude is high. The shading by upper array reduced the monthly generation of the PV system by 17% at maximum.
