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...

I wanted to add this statement after the prior post.
Note the voltage (VMP) of the panel... 18.9.... Most panels run in the low 17's. This extra voltage makes a MPPT controller perform extremely well... You can see 5-10 % or more current than the panel current (ISC) when using a good MPPT controller with this voltage. The MPPT will outperform the PWM controller when in low light conditions too. Like early morning and evening.
A PWM controller operates at what ever current from the panel is avail and does a good job. 17 vdc or less is what they run with and anything above is just overhead.
The Rogue controller offers the best MPPT controller avail..
It comes with the temperature compensation probe.. . You can purchase the remote meter and control too.... Very nice to have.
The only other MPPT controller I would recommend is the Morningstar Sunsaver MPPT....
Get the remote meter and temperature probe... both extra.
I will not get into the specifics about the differences of MPPT and PWM.... You can research it yourself...
