I had to look into this once and it really isn't any more complex than the statement. It's not about UL listing or whatever.
Does it generate electricity from solar? Is it installed on or connected to an occupied residential home? The restriction is that it has to be just the system itself. If you have to replace the roofing material before installing, that roofing material is not considered "qualified." Conduit in a trench to a ground mount is qualified. Landscaping work to clean up after the trench is not. Hilton Dier Missisquoi River Hydro LLC Renewable Energy Design
