Washing solar panels _at all_ would be fairly unusual, and arguably pretty pointless, particularly given they're so cheap now; you're looking at, optimistically, a 5% efficiency improvement, but many studies say more like 1% in practice. If you're in a place that gets significant snowfall such that they're often covered then production during winter is likely to be fairly marginal anyway, so may not be worth your while. |
