Why Solar Panels Work Even on Cloudy Days
为什么阴天太阳能板仍能发电
-
Solar panels generate electricity from visible and near-infrared light—not just direct sunlight.太阳能电池板利用可见光和近红外光发电，而不仅依赖直射阳光。
-
Clouds scatter light, but diffuse radiation still reaches panels and creates usable current.云层会散射光线，但漫射辐射仍能到达电池板并产生可用电流。
-
Efficiency drops to 10–25% of full-sun output, yet modern cells capture more low-light photons.发电效率降至晴天时的10%–25%，但现代电池片能捕获更多弱光光子。
-
Cooler temperatures on cloudy days actually improve panel voltage slightly, offsetting some loss.阴天温度较低，反而略微提升电池板电压，部分抵消了功率损失。
-
Tilted mounting and anti-reflective glass help gather scattered light from wider angles.倾斜安装和防反射玻璃有助于从更广角度收集散射光。
-
Battery storage systems store surplus daytime energy for use during nighttime or storms.储能电池系统可储存白天富余电能，供夜间或暴风雨期间使用。
-
In Germany—a country with frequent cloud cover—solar supplies over 10% of annual electricity.德国常年多云，太阳能仍供应其全年超10%的电力。
-
Regular cleaning removes dust and pollen that block even diffuse light more than people realize.定期清洁可去除遮挡漫射光的灰尘与花粉——其影响远超人们认知。
