Edit: thanks everyone. Appreciate the input! I'll tell them to bugger off, I'm not ready to commit to anything anyway.
I had some door knocker salesmen around today from Smart Energy wanting to talk about solar panels. I'm interested in solar but don't have the funds to invest up front and they said something about a govt funded scheme with $0 upfront.
Naturally I'm very sceptical. Would love to hear from anyone who has dealt with them.
