Valuation of the quantity of electric output from photovoltaic generation system in case of PV module applied to installing to vertical direction; Taiyo denchi wo suichoku ni haichishita baai no hatsudenryo hyoka

Abstract

In general, it is most efficient and economical to install photovoltaic (PV) modules with proper slope. There are room spaces on the wall except ground or roof. The PV modules were installed on the vertical wall, to consider the compensative method for this weak point. When modules were installed vertically, there is an advantage that reflecting solar light as well as incident solar light can be utilized compared with the installation with slope. The PV modules were installed on the roof of building with inclination of 90{degree} facing to south using the roof material as a reflecting material (S90), and with inclination of 15{degree} facing to south (S15), to compare their output. The output ratio, S90/S15 was 0.42. When it was very fine, this value increased to 0.60. When using plated steel plate as the reflecting material, this value increased to 0.74, which provided 10 to 30% larger output than the roof material. From these results, about 50% of module output of S15 can be expected for S90. If receiving larger reflection, there would only a slight difference in the module output between S15 and S90. 3 figs., 1 tab.
