Actually, I had put together a 200 watt system from individual parts for well under $300. This included everythinkg down to screews to attach the z brackets. I have never installed solar but I have watched enough you tube and read articles to believe that I coud do it myself.
The only problem I have is the location of the controller.Since I have not moved my battery inside,I was thinking about putting the controller inside the basement pass thru.Do do this I would have to devise some sort of guard for the controller and components for protection when getting stuff the pass thru.The pass thru does not go all the way thru as the water heater is located on the driver side of the trailer. This would give me wire runs of about 10 feet to the controller and maybe 5 feet to the battery.
