mike95490 said:The last number I heard kicked around, was that after 3 years, solar PV and electric fridge had the cost advantage over lugging tanks of propane. So i'd build the "small system" and use 24 or 48v, so you could easily expand it with more panels and batteries when you want the electric fridge
I think the details were - the cost of 3 years of propane, vs buying 600w more of PV panels. And you don't "have" to leave the fridge and inverter on over the winter, just the charge controller, to keep the batteries topped off.
Propane gets a lot less attractive when the tanks have to be carried to the cabin on a boat. And over time, it costs a lot. With bottled gas over $1.00/day for an 8 cubic foot fridge/freezer.
