But if photovoltaic technology improves as Swanson predicts, solar panels' day as a practical source of power may finally be dawning.

但如果光电技术像Swanson预测的那样改进，作为一种实用性的能源，太阳能的时代终将会开启。

One of the technologies he mentioned was solar shingles, a lesser-known photovoltaic energy source that looks like regular roofing shingles but could power homes more cheaply than common solar panels.

其中提到的一项技术就是太阳瓦，一种较少人知道的观点能源，类似于常规的瓦片但是却能用笔通常的太阳能板更廉价的条件为家庭供电。

Another use could be to provide cooling for giant concentrated solar power plants, which are gaining credibility as a future large-scale energy source.

这项技术的其他用途还有为大型集光型太阳能发电站提供冷却，这种未来大规模能源正越来越受到人们的青睐。

Perhaps the most interesting part of this design is its dual-mode power system, which consists of the standard solar cell array as well as a nuclear power source, allowing the rover to operate continuously and in areas that go long periods without sunlight.
