I noticed a while back that half of my home solar array was frosted over and half was clear.
I figured that one of the inverters must be off line. Any time you are moving electrons you are creating heat, right? Yes, one of them had tripped its circuit breaker, but it was the one that was melted, not the frosty one. Zero current == warmer panel. I am guessing that extracting up to 285 watts per panel with a closed circuit means up to 285 watts lot left behind to convert into heat. Not sure if you could use this to help them melt snow. I don’t think it would work for anything more than a light coating of frost. I wish I would have taken my IR thermometer out to see the temperature difference.
