Re: question about solar power!

as far as cooking goes we were thinking wood or propane for that. and same for the shower. someone previously put a yurt on the site we are considering and used solar power which seemed to work just fine, so i believe it has good exposure and such. has anyone had experience powering these few items with solar? thanks again for the help

The sun doesn't work at night, so you will need a battery bank. In my experience, that becomes the largest expense. Much will depend on whether you can get away with 12 volt system. If you have to bump it up to 24 volts, that's double the batteries.
My camp runs on 12 volts and I run a small LCD TV, lights, computer and some amateur radio equipment. In the summer when the sun is unobstructed, I pretty much cannot deplete my battery bank which consists of 3, 115AH deep cell marine batteries that cost about $120 a piece. I am guessing that with a really REALLY small fridge, I would probably have to double the battery bank.
In the winter up here, it wouldn't work out, just not enough sun to power my two 100watt solar panels.
Keep in mind that you can also get a propane powered fridge. I don't know much about them, but people do use them.
