描述了停车棚结构及电气控制设计方法，并提供了设计效果。停车棚长50 m，宽5.5 m，可停放18辆小轿车，在系统智能控制下，光伏电池发电自动优先给停车棚下停放的电动汽车充电，多余电能由蓄电池储存备用。蓄电池充满电后，光伏电池发出的电能将由光伏并网逆变器直接并入公共电网；当遇阴雨天而太阳能发电不足时，由公共电网自动接入为电动汽车充电。

The photovoltaic(PV) shed system structure and design in detail with the present of its actual photos were described. The shed is 50 m long and 5.5 m wide and capable of parking 18 cars. Under the control of system intellectual controller, the power produced by PV from sunlight will charge the parking electric vehicle (EV) car prior to charge the storage battery, charge the storage battery prior to grid power at last, and charge the EV by utility grid while on a cloudy or rainy day.
