Any advice on investing in Renewable Energy?

1. do you have solar on your house?

w the incentives out there, depending on your location, it shd cost u about half the sticker price.
my elec bills were $150-200/mo, cuz i have grow lights and stuff. they’re now $20/mo and right now i’m banking credits for colder months. my investment was roughly $20k.
i dont know any investment w that kind of return,

i’m in the process of putting them on my 2flat, which i converted to a heat pump. i was able to nearly double rents cuz it’s now heated AND cooled, a rare thing in a vintage bldg. (also did improvements. 2nd br, etc.)
the weather has been mild, but i’m pleasantly surprised how low the bills have been so far. tenants keep it comfy, but my june bill was only $75.
