Ken-
No; I already had batteries, and inverter. The prices I got were for installation of the panels & charge controllers. It was a little crazy, honestly.
Damon-
5.2KW is a lot of power!
I also think that it's AWESOME to make your own power.
The month after we did this, Avista sent us an email saying that they saw "an anomoly" on our bill, as useage had dropped to ZERO!!!!
We emailed them back, and said, yes, we have installed solar panels & a wind generator, that nothing was wrong, and they didn't need to send anyone out.
We got a phone call from them; to wit:
"We think it's great that you installed panels, but we need to send someone out to make sure everything is OK"... code for"we need to make sure yu didn't cut into power before our meter".
They send this guy out, he gets here, looks at all the panels, & mill, and says- "they didn't tell me you had a bunch of solar panels".
We talked for about two hours, after he left, he asked me if I could come over to his house & give him some "pointers" on how to do it himself. Said he hates paying the power company.....so I did.
Pretty cool, all the way around.
