Development of the airflow type photovoltaic system with solar shading effect

The number of zero energy buildings (ZEBs) with photovoltaic panels is on the increase. However, in high-rise building which has low ratio roof area to total floor area, power consumption exceeds electric-generating capacity panels. For that reason, it necessary increase solar panel by installing wall or window. purpose this study develop airflow type system shading effect. First, we external louver integrated can generate power, recover heat from panel, and block sunlight into room. holes at top bottom cause natural convection inside cools improves generation efficiency panel. In addition, taking warm air through louvers room, heating load will be also reduced. Then, verify system, outdoor actual measurement was performed compared non-airflow system. As result, ventilation rate approximately 4.53 m 3 /h, increased 1.70 times than one.
