In the US, a lot of problems have arisen around residential solar installation companies providing loans using questionable, if not outright fraudulent sales tactics based around misrepresenting returns.
https://time.com/6565415/rooftop-solar-industry-collapse/
Companies running solar farms, on the other hand, have bean-counters in place who are in a legitimate position to run the numbers, and those companies take on the risk themselves. With residential solar, it's not companies saying "hey, we'll put our capital on the line, and just want somewhere to put a panel", it's "here's a graph and some numbers, and there's a great investment opportunity for you with your capital...just sign on the line here!" Needless to say, this opens the door to a lot of potential unpleasantness.
EDIT: If a company sends a guy to your doorstep to tell you how they have a fantastic investment opportunity for you and your money which will make you a great return, a good response is to ask them why they don't want to make the investment themselves. Is it generosity on their part, letting you enjoy the benefit of the investment?
If a solar panel installer wants to put panels on a roof I own, that's fine with me. All they have to do is pay me for the space on my roof and cover the cost of the hardware and its installation. In return, I will let them have the entire value of the generation done, rather than taking it myself. If this is a legitimate investment with a valid return for the party putting money down, then they should be happy to do that.
One notices that there are no residential solar installer companies who are engaging in that sort of arrangement. Cell tower companies do that with cell infrastructure, but not residential solar installers. Hmmm.
The whole argument is that you need neither a loan or a professional installer for a Balkonkraftwerk. Your're completely missing the point.
While I agree with your sentiment, I'm not sure the cell tower is a good comparison. Very few if any cell towers are installed on a residential single family roof. Leasing part of your plot of land or space on a commercial or multi unit building is a completely different problem than giving a company rights to part of a frame residential home. Who maintains the roof? Who insures the roof? What insurance company will write that policy? It's already getting more complicated to insure rooftop solar because claims are climbing. Now you've got a roof leased to someone else with solar panels on it? Seems to me like any commercial venture would skip all that and go straight to buying or leasing land. Land with no homes. This is the US after all, we have plenty of that laying around.
Companies are offering rooftop solar owned by the residents because they want it, they want the benefits. The problem is that it's rapidly growing and a great target for scams. Especially considering the age demographic of homeowners who have paid off enough of their mortgage that they have collateral for said loans. These companies should be regulated and vetted somehow.
