$1500 for 5kw of storage? i'm going to call bullshit on that (or are you looking at gel/lead acid batteries?) but if prices have dropped that much, that's cool.   yeah, we've got a couple of 1500g tanks; finally got around to setting up filtration for the spring on our property, it's semi-seasonal, by august it's pretty much dried up. but with 3k gallons of storage we can get by. again, what you're describing is a pretty rough life; if you're making it work, great.
