I have not installed any solar products before and was very apprehensive about it, thinking I would have to have the system installed at a great cost. I especially didn't want to drill a hole in my RV roof. However, after measuring carefully I found the best spot to drill near a vent and did so, and was able to run the wires down the back corner of a closet and into the battery storage compartment. From there it was easy to go up the wall to mount the controller, using wire channel all the way down the closet and up the wall. Fastening down the flexible panels was a bit tricky with butyl tape, but it all worked out great. I have a steady 13.8 volt charge on the deep cycle battery, which is enough to run my small refrigerator constantly. The controller that came with the package does not get hot like was mentioned in the product info.
