Question on Number of Solar Panels
I have a 24'stationary travel trailer that I want to install solar on. I plan on using 2 GC-2 batteries (230ah)in series to provide 12 volts with 230 AH, which I know only 40-50% of that is usable. Be...

Just thought the 400 watts(over the 300 watts) would put out an extra amp or so to keep the batteries maintained when I am not there.
This is about the only thing that solar will be able to do, in your location - maintain batteries when not in use. And it very well might be that during winter and in the mountain shadow a 400W will put exactly "an amp hour" out, compared to 300W. Like in "one amp hour". I don't understand the hesitations about 400W over 300W. Controller will control the charging - this is what it is for. It will prevent the overcharging if it ever comes to this.
BLF is correct - it's a pain always getting a full charge with a generator. Solar is perfect for the last slow finishing stage. You come there once a while, run a generator for an hour or so daily while you're there, and go home. Solar will complete the charging and will maintain it in your absence. 400W will do this better than 300W.
