The aim of this study was to investigate the effect of semi-transparent building integrated photovoltaics (BIPV) mounted on top of a greenhouse, on the growth of tomatoes and microclimate conditions as well as to estimate the generated energy and the payback period of this system. Three modules were settled at 20 % of the greenhouse roof area at a tilt angle of 30º facing south at a distance of 0.08 m between the plastic cover and the BIPV. Each module has a peak power of 170 W_p and efficiency of 8.25 %. Results revealed that the annual generated electric energy of the BIPV was 637 kWh. Furthermore, there were no significant differences (P< 0.05) in the growth of tomatoes between shaded greenhouse by the BIPV and the un-shaded greenhouse. The reduction of solar radiation under the BIPV was 35 % - 40 % more than the Polyethylene covers on clear days. The BIPV shading decreases the air temperature by (1 ºC - 3 ºC) on clear days and has no effect on relative humidity. The payback period was found to be 9 years. Moreover, this system can provide most of the annual energy demands for the greenhouse environmental control systems.

这项研究的目的是研究安装在温室顶部的半透明建筑物集成光伏（BIPV）对番茄生长和微气候条件的影响，并估算该系统的发电量和投资回收期。三个模块在塑料盖和BIPV之间以0.08 m的距离向南倾斜30º的情况下，以30º的倾斜角固定在温室屋顶面积的20％处。每个模块的峰值功率为170 W _p，效率为8.25％。结果显示，BIPV的年发电量为637 kWh。此外，没有显着差异（P<0.05）在BIPV遮荫温室和无遮荫温室之间的番茄生长。在晴天，BIPV下太阳辐射的减少比聚乙烯覆盖的减少了35％-40％。晴天，BIPV遮阳会使空气温度降低（1ºC-3ºC），并且对相对湿度没有影响。投资回收期为9年。而且，该系统可以为温室环境控制系统提供大部分的年度能源需求。
