Is your roof sturdy enough for solar?

Is your roof facing a good direction for solar?

Can you put enough panels on your roof to either eliminate or very significantly reduce your electric bill?

Are you concerned about power outages? (if so, you'll need storage, and storage costs waaaaaaay more than panels.)

Are you planning to sell back to the utility? If so, do you know the laws on how much you can sell back and the rates you can expect to get? Grid-interactive systems cost 3-10x more than off-grid systems.

If you care... What are local codes for solar? There are some legit concerns for the safety of any firefighters and some of the new code stuff is much safer all around, even for you if you ever need to get up on the roof for something.
