We are buying a plug and play off grid system from Wholesale Solar. For now we are just going to set it up and keep as back up for when the grid goes down. We are moving to our mountain retreat and putting all appliances on propane and then 2 one thousand gallon propane tanks. We figure we can go two years eithout a refill. Woodstove for heat. Hopefully that will be good enough. :-)
Oh, yeah, 2,000 gallons will work real good. ;-) A thousand could go for nearly 20 years if used for cooking only.
