My roof mount system is saving me $1000 a year in electricity, plus more in natural gas that I I disconnected, and it was $0 of my own money thanks to a grant and interest free loan.

Electricity is pre approved to increase a minimum of 5% a year (it just went up 16% this year for people out of town), so the savings will only increase.

I’ll pocket something like $35k in 25 years for $0. Best investment ever.

I’m in canada in a tight valley where it snows a boatload.
