Opinions on 100W Solar System
I've done my reading and research and think I have a system figured out. Limited space on the roof of my 815 so plan on going with a single panel. Maximum space available is 52 x 25, but optimum...

bigfootford - please explain why. Which entry type controller would you recommend?
When we want solar to perform a majority of charging as quickly as possible in cold or hot weather the voltage of the charge v/s a cold or hot battery is needed to properly charge.
When on shore power charging with our converters it is not so imperative.
Solar temp comp example of the voltage during boost mode, charging with as much as solar can..
Example of my solar charging:
Cold weather and my batter temperature is 50deg or lower I see almost 15 vdc...
Hot weather battery temperature above 90... 13.8 or so is what I see. This keeps the battery from boiling/ gassing.
There are a few mfg's of Solar controllers that have temperature compensation. You have to purchase the probe... There are a few controllers that have the temp compensation built into the box... If you have the box in the camper it will not match the temp of your batteries in a battery compartment. I like the probe, it attaches to the battery terminal.
