I met that Pika crew at the energy fair in WI this year. Had a long talk with them. They showed me their System and answered questions. Seems cool. But, I have to agree Jay, after this silicon energy and Tenk solar debacle in MN, I’ll only use proven equipment. I’ll be walking away from jobs if people want the new shinny thing. It is absolutely not worth the risk.
