Check out Doug and Stacy on Youtube. They have been offgrid for awhile, yet waited several years before investing in solar.

When you do, don't go with The Big Energy Company in the Neighborhood. They will look at your roof on google, and not actually go up there. They will put you on a payment plan that, after 15 years and WAY more than it would have cost, finds your panels obsolete.

If you DIY, respect the Flashing on the roof. My partner has now been hired twice to remove solar from a roof because of too many holes. Racking system is everything. An array in the yard would be healthier than panels over your heads on the house.
