Not an issue in Orlando, but it's almost impossible to get Heliocol here in the Northeast. I was only able to get one quote from a builder recommended by the manufacturer, and he had only installed one or 2 systems. We were able to find a number of installers that use Fafco.

Is the 5200 installed? If so, it doesn't seem out of line, especially for the Heliocol, which seem to be a bit more expensive. We paid about 5200 for 8 4x14 panels installed last year.
