Installing these on a existing roof would foolish as the cost to remove and replace them would be prohibitive. I have a ground mount system the panels are 450 watts, these panels are 45 watts each. People really need to due there research.

The GAF product like the TESLA roofing tile product has a problem with piercings on the roof, wiring into usuable panel strings and feeding the house inverter(s). Still not sure how these tile strips meet RSD requirements under the NEC. Of course if a fireman has to hack through the roof to vent for an attic fire, not sure it would be as simple as replacing the obviously damaged panel strings. The close proximity to the roof may allow stress cracking of solar PV tile cells that were not breached. The racked close mount of framed solar PV panels seems like a better O&M prospect over something that may last 30 or more years on one’s roof.
