@Mr.Glock is correct I think. The whole marketing thing is a giant scam, IMO.
My next door neighbor had a bunch of panels put up. Couple of weeks later the contractor was in his house all day, I'm assuming connecting the inverter and turning it on after inspection. Guess not... A few days later that, a crew shows up at about 5:00PM and hops up on the roof and takes EVERTHING off.
This is just me guessing here, but two days after that a semi truck pulled up and unloaded roofing supplies. I'm guessing that it wouldn't pass inspection since they were actually missing shingles and had bare decking showing in spots. They now have a nice new roof, I don't know if the panels are going to go back up or not, The signs are still in their yard, but what freaking kind of contractor would even agree to install on a roof in that condition?
Also, these people are of retired age. There's zero chance they get their investment back before they die. The man there can't even mow his yard, he has a nephew come over a couple times a month and do it. Solar panel systems are a 20-30 year pay back proposition, but they spin it like it's the greatest thing ever. I have no love at all for these companies...
These solar panel salesman were hitting Piedmont hard and it was the elderly they were targeting. What’s sad is a lot of these companies are based in Utah and they employ former Mormon missionaries as their salesman. Utah is the scam & MLM capital of our country. They use former missionaries cause they are not afraid to knock on doors and try to sell you something you didn’t want.
