I have a small solar system that provides power to the radios in my shack. I run my 200 watt Kenwood TS-480 completely off my solar system. The main panel in the center is a Kyocera KD135GX 135 watt panel that powers the system. The small 15 watt panels on the sides of the mail panel only there to charge small 12v batteries.The panels are mounted to a homemade aluminum stand. An aluminum weather prof box is attached to the stand to house the charge controller and any small SLA batteries that are charged by the small panels.
