The panel already installed is a renology 100w mono crystalline. I installed it as a test bed for my solar system. So far so good. I will install the next one in a week or two, and monitor results. I have a 1800 xantrex inverter, all wired up with 0/4 welding wire. I work in the aviation Iindustry, and am building the entire electrical system with redundancy. All the lighting is LED, and uses vert little power. There is a 1000w rv microwave installed in place of one of the original ambulance cabinets. Still working on it, lots left to do, and ever changing. I figure out something that will work better, and modify as needed. I have already spent a month in it on work related travel. I stayed at a campground with no issues. Getting ice got old pretty quick, but now I have one of those fancy pelican coolers, so time will tell.
