Solar panel and snow load
I would like to put a solar panel on a RV that I leave in North MN. Will a panel take the snow load and -40 temps? I know it will not charge under the snow but should charge in the fall and spring.

Keep in mind that most so called "flat" installations are slightly tilted, because it conforms to the roof slope. Unless your roof is totally flat - and in this case you'd better install the panel with slight slope, about 3 degrees, to drain the water and dust. This will help against snow accumulation as well. Lift one side (the one that is more likely to be the North side) about 3/4"-1" higher than the other side. Don't worry if the lifted side will become the South side at times - minus 3 degrees won't do much harm, and the other times it will work better than flat.
Landstar looks like a decent controller - it says "setpoints user defined" ? - if this is so, it's good.
