Best company I’ve worked with so far is SunPower. Spanks recommend them to me and he loves it. They mfg their panels and install their system’s, no 3rd party sourcing, and have truthful sales reps… if there is such a thing. Basically, if it doesn’t make sense, they will tell you.
We haven’t pulled the trigger yet but with the bill Biden signed increasing the FTC to 30% and extending it another decade, we’re not in a rush. The technology is constantly improving. We have shade and our roof is not ideally faced so I’m thinking the panels become more efficient over the next few years where the decision becomes a no brainer. As it currently stands, we can get 88% of our annual electric usage via solar. So I’d like to wait and shoot for 100%.
