An electricity and crop producible greenhouse equipped with a roof mounted photovoltaic array

温室屋顶面积的13%的光伏阵列连接在东面的南面屋顶上。西向直线型或棋盘式单跨温室。分析了光伏阵列产生的电能和光伏阵列遮荫对大葱生长的影响。结果表明，棋盘式光伏组件布置可以缓解遮荫对植物生长的负面影响。估计了光伏阵列和逆变器的农作物收入损失、电力收入和成本回收期。

A PV array with 13% of the greenhouse-roof area coverage was attached to the southern roof of an east. west oriented single-span greenhouse in the form of straight-line or checkerboard. Electrical energy generated by the PV array and effects of PV array shading on the Welsh onion growth were analyzed. The results indicated that the negative shading effects on plant growth can be mitigated by the checkerboard PV module arrangement. Crop revenue losses, electricity revenues and the cost payback time for the PV array and the inverter were estimated.
