')They ARE expensive. A set of lead acid forklift batteries suitable for home use costs like $5,000 and is really heavy.
Is that with or without shipping costs? You pretty much NEED a forklift to move those batteries, don't you? It must be like moving a player piano into your house.
Anyway, if you do the math, that's $41 a month spread out over 10 years, assuming you really get 10 years out of them. Then it's lather, rinse, and repeat. It's not that hard to keep your electric bill at or below $41 bucks, and that's JUST for the batteries, not turbines and/or PV array.
The least one could ask for is the up front expense on a renewable system to be a
one-time-only thing. That would be true of PV and inverter, but not the battery bank.
Something like EESTOR would really help there.
