The snow finally slackened off around 10:30 and I went outside to clean off the solar panels on the ground mount. Turned out I could’ve stayed indoors…
That’s not supposed to happen. Here’s what the roof-mounted panels were like at the same time…
The ground mount panels are at a steeper angle but so were the old ones and they never spontaneously cleared themselves while it was still cold and grey. Is a puzzlement.
