Solar panels for a rental

[Kenny Hardcastle]

I'm currently considering putting on solar panels for my duplex in Cleveland Ohio for $150 a month. The solar panels would cover the cost of both units and if there is any excess energy I can sell it back to the grid, at a minimal gain. Where I think this will add value is I can increase the rent of both of my units by $100 to $150 each. I would be able to cover all utilities for both units. 

with the tax incentives and energy rebates I could potentially save an additional $3,000 a year, not to include anything I sell back to the grid.

it is also estimated that I will raise my property value by $4,000 by adding the system.

has anyone else done this with their rentals? Or had any experience?
