Roof Facing Question

[Greg29]

My best roof facing direction is 132 degrees in Orlando - so not optimal. I think I get about 90% efficiency relative to due south? Is it worthwhile to invest in panels and powerwalls? I know that's a subjective question so interested in perspectives and experiences here.

It also depends on the design of your roof. Your best bet would be to get someone to come out and look.

I agree that the best way to get more information is to get some quotes from solar installers.

However, you can get some information online from Project Sunroof (I found Google's estimates to be on the low side). Plugging data into PVWatts is likely easier after you've gotten some estimates. Ideally the estimates will be based from someone doing measurements from your roof but some installers may only provide an estimate from satellite imagery.
