EVSE Installation, Info and Cost Comparison Thread

Fri Jun 25, 2010 10:19 am

I am starting this thread as a place to post any info on EVSE installation costs, parts, etc. This will be a good way to get ideas of what people are being charged and what info is being communicated.

I'm not sure about some of these UL excuses, from the conversations with PGE some of them seem to hint at other possible political reasons. I may need to call my local city and ask them why they are so inflexible to EV owners.

I imagine dual meters may be problematic for municipalities when used in "in-law apartment" situations. Both from enabling living arrangements that may violate ordinances, and in situations where disputes arise between the 2 parties, payments aren't made, service is disconnected, etc...

The first wave of owners are going to be blazing the trail. Hopefully once a critical mass is reached, the utilities will take more reasonable steps to accomodate. It will serve them well to make off-peak charging as attractive and as hassle-free as possible. The same applies at the legislative level. Off-peak charing is important for maximizing the benefit of the new technology in terms of existing infrastructure. It would be folly to have TOU be so unattractive that we start experiencing capacity problems early into the wide adoption of EVs.
I noticed you're still working with polymers.

An easy inspection for single family homes can clearly show if the application is correct.

The TOU meter piggy backs on the existing meter and takes power from the grid BEFORE the existing main panel. You get an additional 40 amp service without a major panel upgrade. A 40 amp disconnect is required by code near the TOU meter along with a second one near the charging unit if it is more than a certain distance away. SCE off-peak charging hours are 9:00pm to 12:00 noon
So was this the TOU-EV rate schedule? It sounds pretty good to me, and would help me avoid any issues with my panel, which I'm still a little wary of until the AV guy says it's workable.

So did that put your house on TOU too, or can it stay on the Domestic rate schedule?

The only thing PG&E warned me about for the second meter was that I might need to upgrade my supply lines at considerable cost (they're underground). An electrician could look at your service entry and tell you if yours would be OK without an upgrade, a duplex service entry is a pretty common installation.

I'm going to try to ask my Nissan EVSE person to quote my installation two ways, straightforward add-a-circuit and and also add-a-meter.

Did we talk about this already....does the EVSE credit carry over or is it a one-time deal like the EV credit?

If I get my car this year AND my EVSE, I would be much better off putting as much of the EVSE installation (in terms of panel upgrades and such) on my PV system install, since the credit for it does carry over!

EVSE credit has a 2K limit ... don't know whether it can carry over.

For Charge Stations
Tax credit equaling 50% of the cost to install an EV charge station, with a maximum $2,000 credit for each station installed.

So total cost could be up to $4,000 and still receive full 50% credit.

I hope this is on topic. I didn't want to start a new thread, but wanted to remind everyone about the AMT limitation. I realize that there has been some discussion of this along with discussion of the $7500 vehicle credit, which is handled differently.

It appears to me that the Federal 50% EVSE tax credit is eliminated completely if you owe even $1 of Alternative Minimum Tax.

From my amateur reading of IRS form 8911 on Nissan's site: http://www.nissanusa.com/ev/media/pdf/i ... ive-56.pdf line 22 reads that if you subtract the Tentative Minimum Tax from the Regular Tax and the result is zero or less, "stop here, do not file this form" unless you are filing as a business.

To me, that means "sorry, you don't get ANY of this credit if your tentative minimum tax equals or exceeds your regular tax".

I paid about $1,000 of AMT in 2009 and I'll probably pay some in 2010, so I'm assuming that I'm s**t out of luck for this credit. That's important for me to know as I evaluate the AV quote for the EVSE install that I expect in a few days. I ran into a similar limitation for the 2007 tax year, when I installed solar PV and bought a Prius. I didn't pay AMT in that year, but my $2,000 federal solar PV credit eliminated my ability to take the $750 hybrid car credit because of the affect of subtracting the $2,000 credit and how that affected the tentative minimum tax calculation.

AMT often affects certain taxpayers in high tax states like California, where you are pushed into the AMT by deducting the high state income taxes. So yes, we in CA are in the early roll out markets, but there are drawbacks.
