A residential solar-power system consists of just three components: the PV modules, a battery storage unit, and a charge controller. Such a system can supply low-voltage DC electric power at five volts for mobile phones, and 12V for LED lighting, pumps for outdoor use, and electrical appliances such as computers and televisions.
这种方法同样非常简单。住宅太阳能发电系统由光伏组件、电池存储单元和充电控制装置等三部分组成。这样一套系统可以满足5V手机低压直流充电、以及12V LED照明、户外水泵及电脑电视等各式家电的用电需求。
