Thanks for the input everyone.
Couple of more items to address some of the questions/suggestions.
I've no doubt the low solar gain at both Ocean Pond and in the Everglades was influenced by the shadowing effect of both the a/c shroud and the MaxFan being raised. No secret that shadow on even a small portion of a solar panel reduces efficiency of the panel. Considering the location of the 95w panel, shadowing at some time of the day is a fact.
I have seldom see a 5 amp output from the solar panel for any length of time (theoretical max is 5.3). Angle of the sun, shadowing on the panel, shade, haze, partly cloudy skies generally kept the output below 5 amps. I usually see a slightly lower amp input reading on the Trimetric than I do from the GoPower controller.
I do have the Interstate GC2-XHD batteries. I did change out the main board on the WFCO 8955 and replaced it with a PowerMax Boondocker 4 stage converter/charger. The 4th stage of the Powermax is a "desulfation mode" which raises the voltage to 14.6 once a day for 15 minutes when the battery is in the storage (float) mode. Still less than the 15.3v equalizing voltage recommended by Interstate, but it's what I have. At the completion of my solar testing at home, I used the converter/charger to recharge the batteries. It required 9.5 hours to return to the 96% charged state and an additional 24 hours to reach 100% charged (as measured by the Trimetric monitor).
The average use during the periods tested while we were traveling was around 45 amp-hours per day.
No question I'll have to add more solar panels and likely change the controller. I'm comfortable with doing most anything, but mounting solar panels on the roof isn't on my comfort list right now.
I will be contacting AM Solar in Springfield, OR to see what they would recommend (gives us a reason to head west again
). I'm going back and forth between roof mount and portable. Maybe I should just mount a panel(s) on the Pilot's roof racks and make them adjustable so they could act as air deflectors and improve my MPG at the same time.
