Nautilus (Community) Solar Energy

Yesterday a person claiming to represent the above entitled company (I have no reason to doubt him). Came to my door. He asked if I wanted to become part of Nautilus. To be clear they are not installing solar panels. They are signing residents of Peoria to be part of the program. At the time I told him I wasn’t interested. I looked up the company. It’s legit. These sorts of companies are initiatives, apparently set up with the assistance of the Legislature, to offer solar energy. The rep who came to my door claimed I could save 10-20%.

I’m interested if anyone has signed up with Nautilus. Apparently it’s hard to un-subscribe from their service as a downside. I’m wondering if people see this reduction in costs. Also I’m curious how solar credits work in Illinois, and more general how this all works. Only info I found from current customers was on the Maine subreddit. I imagine their laws are different regarding this. Thanks for any help.
