I can believe that, same as the water tank installers that have sprung up everywhere. When we were getting quotes some of them didn't even have a lot of common sense much less technical expertise.
and then there is the issue of the the quality of the panels they offer, long term reliability of their invertors etc etc.
It's the old story - you get what you pay for - most of the time.
And if it sounds to good to be true - then perhaps it is.
