There are no solar rules.
Here we are camping on the North-West Coast of North America, and if it is warm enough at night (sometimes) no furnace needed. In that case our daily AH draw might be a mere 70AH. The solar can do way more than that (if the weatherman would ever get it right)
That would include the 2000w inverter drawing over 100a for running the microwave, toaster, and kettle as required. We also watch a movie on the tv/dvd, and also of course there is the dreaded laptop, so we can keep up with rv.net.
On average, that would take a 200w ish solar set-up with PWM and four batteries. Once in a while, when "summer" fails, we have to crank up the gen to catch up. But having "more solar" wouldn't help with that since when it gets cloudy, it doesn't matter how much solar you have
Almot, the Calvanist camped next door, frowning at our excessive AH usage (but no gen noise except during allowed gen times) only has to worry about a Sheltie barking when he gets too peeved at us and starts throwing things :)
