Let me explain this to you. I'm not at all anti-solar. I have a bunch of self installed panels on my garage at my northern home and they work great for that.
You need to understand how most of these companies work. You sign a contract for the panels and you pay for them under some financing model that they came up with. They agree to pay you for some of the energy that's generated.
The problem is, that they often structure it so that even with your whole roof covered in panels that you're paying for monthly, they decide how much of the energy that the utility company pays for ends up in your pocket. They usually structure it so that any subsidy is given to them, NOT you and then they collect money selling all of that power to the utility and give the homeowner a small cut of that. You can end up with a roof full of panels generating $500/month more energy than you use, but they structure the contract so that you sometimes make $0/month and are stuck paying for the panels on the roof for 25 years while the solar salesperson made $10k on the sale.
Here is an informative unbiased article about that.
