Hi....I'm a DIYer and need to replace three sections of 4'x12' Heliocol solar panels, HC50. Along with new clamps, o-rings, and gator mounts. Can't seem to find any online dealers where I can buy from. My local dealer wants $420 each for the HC-50 panels. Seems high to me. Anyone know where I can buys these either in southeast Florida, or online for a good price? Reply here or PM.
