It’s been very cold this week in the Hudson Valley, and our solar array hasn’t been able to melt itself free of the snow. Anybody out there have some special tricks to get rid of it? 

We’re missing some primo clear winter days up here- solar panels actually work better in the cold. A solar panel is in some ways just the cold side of a heat engine, just like the condenser in a steam power plant. The sun is the hot side, and energy can be harnessed because of the difference in temperature between the sun and our roof. At least sort of.
