LOL! Just make sure you follow the suggestion to slant your solar panels enough for the snow to just “slide off”.
LOL! Great salesguy, there.
Yeah. Ice doesn't just "slide off". Ditto wind-driven snow. Or, just a heavy Frost.
I'm from Maine, and have a little exerience in such things. (/s) Or, if my word isn't good enough, they could just take a look at their car in the driveway on a wintry morning. :-)
Then they are inefficient in the summer.
And I don’t know how he’s going to get around all those overcast days.
