alt Hacker NewsI clean my solar panels, 7kwh, every monmth or two.
When I check on the VRM portal it makes a difference, and since I am so dependent on them all year round, I have no problem giving them some attention from time to time. Ten mins well spent.

This honestly sounds like a non-trivial strike against installing solar panels, especially if they’re installed on tall roofs.
I definitely wouldn’t want to have to clean them that often, or pay to have them cleaned that often.
If you’re spending only 10 minutes on them, then maybe you don’t have that many, and they’re not up high.

I am curious how much of a difference it makes.
I have 4kw of panels and 15kwh of storage. I only get down to about 80% most nights (I heat with wood and propane).
But my system will charge completely in about 2 hours of full sun. If it took 3 hours it wouldn't make a difference. So I generally don't clean them (well, the rain and snow do that work).
I do remove snow, because that has a very noticeable impact.
Is the difference that you are pushing back to a grid (I am not), so the power all gets used regardless of you being the one to use it?
