How much solar to stick on a 22-24 foot "C"?
I am looking at class "C" rigs, but at best, they might have 100 watts on a panel. Realistically, for a shorter "C", how many watts should I be expecting to shoot for, on the roof? The battery bank ...

On my 22' Montara ('93) there is room for two 130w Kyocera panels mounted lengthwise in front of the ac and one 140w panel mounted sideways behind the ac for a 400W total. With a Rogue MPT 3024 controller on this partly cloudy S. Texas day (11AM) the output feeding 4 US2200 batteries (464AH) is 13v / 10 - 18 amps.
Battery charge is usually @ 12.4V when I start my day at 5AM and the generator will run until the Rogue starts to put out > 12.7 which then carries me thru the day. I run two 18" laptops and two 21" monitors from 5AM until 4PM so my draw is likely higher than most, but even so, solar is cheap and you can never have to much. The panels are wired in series outputting 12V and have thought if a forth panel was added I'd go parallel for 24V and a Winter power boost. However, with that setup there may be an issue with the max wattage the controller will tolerate and given the short distances involved, voltage drop is not really a concern.
You got your series and parallel reversed, Maybe edit the post? If you do then I will delete this post.
