$1/watt cost of parts if you do it yourself. Take your annual kWh usage. You can normally download your records from the power company or they will send them to you. Say you use 18,000 kWh per year. Divide that number by 3 and that is a reasonable size of wattage to install. So in this example 6000 watts. If you are in a net metering situation, that will eliminate 2/3rds of your power bill.
That will cost you about $6000 if you are careful in purchasing.

I was quoted $25k in panels at the time … think I may revisit though and get additional quotes ;) BTW – a friend of mine has a Tesla S and loves it… I’m seriously considering one now as well From: Af [mailto:[email protected]] On Behalf Of Chris Wright Sent: Tuesday, May 5, 2015 11:31 AM To: [email protected] Subject: Re: [AFMUG] This is going to make a great UPS I don’t know how many cycles it can handle, but max draw per pack is 2kW continuous, 3.3kW peak. http://www.teslamotors.com/powerwall Chris Wright Network Administrator Velociter Wireless 209-838-1221 x115 From: Af [mailto:[email protected]] On Behalf Of Bill Prince Sent: Friday, May 01, 2015 10:38 AM To: [email protected] Subject: Re: [AFMUG] This is going to make a great UPS I would want to run it DC, but it ain't bad. We're paying in the neighborhood of $1500 for about 5KWh with SLA batteries, so this would be a serious consideration. I'd like to know what the maximum draw-down is, and how many charge/discharge cycles, etc. etc. bp<part15sbs{at}gmail{dot}com> On 5/1/2015 10:20 AM, Peter Kranz wrote: I want to see more specs, but a 10kWh AC UPS for $3500.. �that�s a decent price. � http://www.teslamotors.com/powerwall � Peter Kranz www.UnwiredLtd.com Desk: 510-868-1614 x100 Mobile: 510-207-0000 [email protected] �
