Resinc Solar

I had a very enthusiastic door to door salesman yesterday from Resinc Solar. Advising they have been installing in the area. He was boasting about all the solar they have installed for SLS clubs on the central coast. He was very pushy. They have a heap of great google and Facebook reviews. Just not sure if they are legit. Door-to-door gives me red flags..

Has anyone delt with them?
