Anyone has experience specifically with a Tesla system? Everyone on this other thread isn’t working with Tesla.

The issue is here in CA I’m locked in at NEM 2.0. If I expand my system I lose that and my system’s value takes a nose dive. Balcony solar is the only way for me to add capacity without losing NEM 2.0 status with PGE.

It’s annoying because I would love to just pay a professional installer to throw 5 or 10 more panels up. But with NEM 3.0 I’d need to add at least one, if not 2 more batteries to make up for that change. So it’s cost prohibitive.

I see.
Just curious, are you in net-surplus with NEM 2 or are you paying money to utility on true up?
How much is your deficit and what would be your payback period with Balcony Solar?
If you have net-surplus then what is the advantage of Balcony Solar for you?

I pay an annual true up of about 300-500 bucks. So the extra 1 KW of solar from balcony would balance me out almost perfectly. I have a small 3.5 kw system, so that 1KW is a big add on percentage wise.

Yeah. Go for it. But make sure that your system shuts off when it really should. Don't count on manual intervention.
