What do you mean they never happened? I know for a fact there were installs done with them and they were still offering them for installation in some area for years because I priced them out. They just didn't get many people to go for it because the price was ludicrous and the product was unproven. Also, you clearly have no idea what you're talking about with solar panels, if your roof is a good candidate for panels there isn't some "shady side".
