The system generates a direct current, so using it to power DC devices locally is more efficient than switching to the alternating current needed to feed it back to the grid.

该系统产生的电流为直流电，所以用来驱动本地的直流点装置比将其转化为交流电输入电网来的更有效率。

Direct current (DC) Direct current is current with no reversals in polarity.

直流直流是指没有正负极性往复变化的电流。
