Not against the solar idea, just hate the convoluted system

So had one of those solar program guys come to my door and try to sell me on their system three days after cancelling the system we were on. No matter how they try to explain how it works it just sounds convoluted. They take 15% off the utilities and then turn around and charge 15% as a separate bill. There was something about credits and mentally I'm just somewhere else. Nope, I'll just pay my utilities as one payment thanks.
