  • For context, I’ve got experience with midsized solar and currently have a balcony-esque 500w array mounted for the correct angle for my latitude. My panels are free but the battery and inverter were about $600. I save 10-15 cents a day in summer. That’s a ridiculously long payback and it doesn’t give me enough for a backup. If I had 2-3kw solar it would be different, spreading the inverter cost more thinly.

    It depends what your consumption is I suppose. If I am able to generate 20% of my consumption that’s a help, maybe I’m wrong, I feel the 500kw balcony vertical install won’t cover 20% of a household.
