I have heard great things about Powermat. Looking at their website as a technical person, it all works. I would really go with them if I had it to do over again. I went with a system that is manufactured by Gull Industries in CA and I am not really happy at the moment. My dealer decided to leave the solar pool heating system and I need service and they are terrible at this. I have called Gull directly and they are no help. The initial design was actually not great.

Ken at Powermat has gone to a lot of trouble to make his designs really work. I would support his efforts if I could.
