prices

lithium isnt 1$/w

its .375$/w or 1920$ for 4.8kw

why do you say they last twice as long? lithium is rated for 2000 cycles to 80% capacity? the only way to get more cycles with the rolls is if you only do 10% depth of discharge with it no? I have read that 10% DoD on lead = 4000-5000 cycles, but 25% DoD makes it down to 1000-2000 cycles. is this correct?

The actual kw used per day i expect to be 2kwh, many calculators i have found say to get 2kwh/day i need usually around 1kw in panels to account for the poor months.

I would need i think 12-15 hours each day worth of no sun energy. So 1kwh to 1.25kwh.

So in order for there to be only 10% depth of discharge with lead acid, i would need a 12.5kwh capacity battery no?

that would cost 2750$ according to the .22/w figure.
