While great information, my cabin will never be solar powered.
We get winter here, 20 feet of snow, -45 temperatures, and I'm not going out there every snowfall to clean off the solar panels.
So they will not be charging, and then the batteries will go dead, freeze, and die.
Propane appliances just sit there turned off, and when I go to the cabin I light them, and they work.
The cabin has no running water, we take drinking, cooking, dishwater with us.
My jumpstarter power pack comes along to charge phones. In winter we don't get there during the coldest days, we will go at -15 C and snowmobile, ice fish, sit around the fire pit.
