Experimental analysis of indoor illuminance and daylight distribution compared to the generation performance of silicon based PV window system

In this study, indoor illuminance and daylight distribution compared to the generation performance of PV window system are experimented and analyzed in accordance with the types of silicon (crystalline, amorphous). According to the analysis of generation quantity during the measurement period, when solar radiation is 138.1kW, daily maximum generation quantity is 27.4kW (19.8% of efficiency) for crystalline PV window system, and 5.8kW (4.1% of efficiency) for amorphous PV window system. In addition, according to analysis of indoor illuminance and daylight distribution, the illuminance of 500lx is secured from all measuring points, and in the case of daylight factor, more than 1.5% of minimum standard (BS 8206-2) is indicated. Therefore, it is analyzed that the lighting performance required by residential environment is satisfied by crystalline as well as amorphous PV window system. However, in the case of illuminance uniformity, crystalline PV window system are analyzed to be 10.5% lower for the measuring height of 400mm and 48.6% lower for the measuring height of 850mm compared to the amorphous PV door and window system. © 2016 SERSC.
