On consumption or investment?
Just got mine installed, 30 panels. If it's sunny, I'm producing more than my household consumes, even this time of year, with me running heat pumps. Overcast, not so much. We're also facing near due south with almost no shade, so that helps.
Investment wise I'm looking at a 5 year return at best, 7 at worst for everything (solar and pumps). Best part of the pumps will be the cooling. Stoked.
