My set up was a bit different but I put them On the roof of a building. Got a payment up front and a new rubber roof layer. They got a 20 year lease.

The issue was the project sold 4 times in a couple of years. And each time it sold everyone in the condo complex (there were 6 other buildings)had to sign off on several legal documents, get them notarized and reviewed by attorneys. It took me several hours each time to compete them and get the other people to sign. It completely turned me off from every doing solar in a commercial setting again.
