Have you talked to your HOA and read the CC&R's? If your complex is newer, the issue may have been addressed. Does anyone else have solar panels in the development?
In Arizona, leased solar panels make it much more difficult to sell a house. The selling price is usually lower than a house without solar panels, and the market is smaller. The lease payments make it harder to qualify for a mortgage and buyers are leery of leases. I would be skeptical of claims of value increases because of solar. I would want to see a paired sales analysis before I bought into that.
Finally, consider waiting. In California, the maximum kilowattage under NEM 1.0 has been reached. You will be under NEM 2.0, which is much less favorable to the customer. This change should be priced in by next spring as word gets around.
