My wolf creek has 2 100w panels on the roof.
It has an RV cover over all winter.
I have two 27 series AGM batteries.
I have a cutoff switch so I can turn off the RV, but I have it wired so solar will still charge the RV.
All winter my batteries have never gone more than a couple days (unless snow is on the cover) without being fully charged according to the Bogart Engineering Tri meter.
during the summer I can leave the RV with power turned on, and refrigerator running on propane, in the woods (solar panels might get 6 hours sun per day) and the two batteries always stay charged.
I have sat in the RV and watched several hours of TV, with lights on, and Refrigerator running on propane, during summer and batteries are always fully charged by 10am.
This is two of the Renogy 100w panels, being controlled by the Bogart Engineering solar controller that matches the TM-2030-RV meter I have from them.
