no batteries YIKES I can't imagine what happens to that trailer if a bunch of cells go off when charging

Li Ion is well known for it's instability.... BOOOOOOOM

The meter spins in reverse during the day and you build up "credits", these "credits" are then used at night when your drawing power off the grid. So if I generate lets say 20 kwh in one day off the panel, my electric bill is reduced at night by the 20 kwh I've built up. It's a net wash. I pay only for the electricity I use from Nat Grid. If they don't give me enough juice then at the end of the year they give me the money difference I had to pay Nat Grid. I will be able to watch the whole thing on a computer like Buzz does right now. If the system don't work like they say then it's their job to take it out and leave building in as previous condx. No cost.

AKA: Chevy Volt! I think I read the Volt is changing to this new A123 type of Li-phosphate battery for storage, less chance of a BOOM?

That's got to be a BIG monkey on their backs.

Your just seeing the tip of the iceberg.

Who has replaced one of these batteries so far....would love to hear the cost....and the disposal costs... lessee if your rat trap is so ecofriendly now :smash:

I'll bet a Prius is no small change.

VOLT was specced at 14K for the battery

hahahahahaha how many people you think are going to dump that kind of dough into a 5 year old car..

My Prius came with an 8yr/100K warranty on the battery. I figure I'll just drive my 2004 with 96K miles into the ground as replacing the battery will not be worth it! There are owners with over 300K on Prius so not sure what the determining factor is: general age, charge cycles, miles, or combination of everything.

Best way might be to have the car in a rear end accident and get the insurance $$. Not sure how accurate from one source: "The hybrid packs cost under $2000 new and under $1000 used. Only a freak few have needed replacement due to normal use. The main need for replacement has been from auto accidents that physically damaged the battery pack enclosure."

I must have missed your mention of that above.

With all that in mind, definitely seems like a no-brainer.

Johnny when I get some time at the shop I'll scan all the stuff and post online.

It'll probably be after the first of the year so if anyone is thinking of this do not wait. It's got to be more expensive next year if indeed the tax stuff ends this year...

Today was engineer visit. Measured the roof. Math doesn't add up. Says the panels are 39" wide, my roof is 17x34, they said 3' in all directions clearance for walking on the roof, that adds up to 18 panels not 26 so that's like 4.8kw instead of 6.8 kw that they were talking about. So that would be 1/2 of my electricity.....see what they come back with.

Do you have a sunny ground location that you would want to sacrifice for additional panels? No more mowing.....

no I don't want anything in the yard.
