Most of the systems on the market are pretty good, it's a highly regulated industry. I think a person would be ok as long as they didn't buy from the Dodgy Bros. Solar Company.
I still have that other place and enjoy the benefits of almost free power. None gets used at night there, and with no power draw at night there's no cost obviously. I don't have a battery there either, I moved out so there's no point with no usage at night. Here though, the battery will happen.
Dodgy Bros expanded into solar too? Damn, though I'm also not surprised XD
Haha!
