Research Abstract

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.
