I’m a little wary of plug-in solar in the US. Some of the bills propose allowing 1200 watt panels which can overload wiring depending on what else is on the circuit and how in the wall wiring is run. Limiting plug-in panel wattage to, say, 400 watts might be necessary
I live in SE MI. There are two things working against residential solar here.
First, in terms of peek sun hours it’s just not a great proposition. Yay cloud cover and short winter days
More importantly, we no longer have net metering. If you generate surplus energy you can still sell it, but you sell it for below what you would have to pay it for.
see that is what im talking about. residential should buy and sell by the same hourly rate if they want to. If you don’t want to sell you can opt out the hourly rate. again they would have to have the law say that if changed any current user gets to keep it grandfathered so anyone who buys panels won’t lose it.
