solar panel install
I wanted to ask a couple questions on my solar plan. I am looking at ordering one of these 200 watt kits. Renogy 200 watt kit I plan to put this on my truck camper. I would like to be able to mo...

thanks on the recommendation.
I just looked at the Eclipse.
it offers me the same 100w, in a 6" shorter package,
Module efficiency:
Eclipse 100W Monocrystalline: 18.35%,
regular 100W Monocrystalline: 15.47%,
100W Polycrystalline: 14.56%.
correct me if I am wrong here:
I can buy 2 eclipse for $440.00 and have 3% more efficiency.
Savings of 6" per panel but still have an output of 200w.
or I can buy 3 old version for $420 and have 50% more power = 300w.
to me cost is more of a factor than space.
also,
looking at 200w kits with PMW controllers cost $339.00
that same kit with MPPT controller cost $499. so this $160 extra for MPPT yields you what, 1.5 extra amp under ideal conditions?
Take the 339.00 2 panel PMW kit and add one extra $139.00 panel to it = $478.00
now you got 300w, and saved yourself $20.00 over a 200w MPPT system.
To the original poster. I would call renogy tech support and ask them is it OK to disconnect the controller from the battery while solar panels are still connected?
Your only going to see power on controller with no battery if you were to pull camper outside before turning on battery switch. (which could happen)
I know how hard it can be to run wires through a camper. I would be tempted to do exactly what your describe if I needed to.
