Newbie solar questions

Thank you everyone for the answers and advice. It sounds like the single panel will be more than enough. No CPAP and when we camp in the winter we will use a catalytic heater instead of the furnace. Like MEXICOWANDERER said, we won't be camping in any extreme temps. We'll head to the national forest in the summer and the coast in the winter.

MEXICOWANDERER-we have ridden bikes past Manzana Co numerous times with the kids, but I've never tried their apple sauce. I'll have to look for it now.

Thanks again everyone,
Ken
