I paid $161 230 watt panel’s free shipping 40 panels
I paid $177 a panel for my 240 watt panels. 14 panels
That is great news for your state!

I am glad I installed solar when I did the prices were right.
I do wish I had power CO. rebate like you did.

We are at $1.72 watt installed before rebates for 11.6 kw. This is 0.78 watt after rebates. Fed 30% SC state 25% this should give a five year payback

Hi,

How did you figure your payback ? My arithmetic says faster but I may be off in my assumptions how much the panels are generating.

Addendum: Second thought -- it makes sense at 1.6 kWh/watt*year since your panels are not at optimal tilt. Still -- fantastic!

The EV non-refundable tax credit applies to the first $7500 of tax liability. If your liability is less than $7500, the tax credit will zero the amount.

Tax_owed = Tax_liability - tax_payed.

Right, I'm retired so it's basically meaningless for me. If it wasn't I'd buy an EV tomorrow.

If you buy used the prices are decreased by this amount with extra depreciation.
If you lease the leasing company gets this money and they discount your payment to reflect it.
That all being said I wish it was a rebate and not a credit.

I'm looking into used Volts now, I think once the 2016's hit the road I'll get a really good deal. I'd like to get a 2014 or a 2015, I should be able to get one coming off lease, maybe next spring.

I'm sure you know your tax situation well, but being retired does not necessarily mean no tax liability. Even SS is taxed above a threshold amount.

I'm in your situation. No tax liability to take advantage of the tax credit. Even though I work and am paid quite well, most of my income is sent to retirement savings so the end result is the same.

The follow-up comment though is exactly right: a used car should pass most of the credit on to the secondary buyer.

ELGo,
Thanks but for the last several years I have paid little to no tax. Things might change, I'm doing more magazine articles now and will be starting to sell circuit boards again. I'm just rebuilding my web site:

all you guys with your fancy charts. I had to try it. So after some labourious lamenting of libre office calc. I get a total of 317,120 watts over the last 82 days. Ignore the 0 watts day. I loaded new firmware for my controllers that day and it left me with an extra day at 0 watts.

I'm off grid. So the chart outlines the power I created and used. The days I run the dishwasher are pretty easy to spot. ;)

and also for comparison: In the spring of 2011 I paid $500 each for 4 250 watt mono panels (red: Panel set A). I then bought 2 more at $425 ea. I later found 2 more at $200 each (Blue: Panel set B). All the panels were used.

I run two 1kw arrays. One fixed (B) at 60 degrees. And the other is adjustable (A). Here I set 30 summer; 45 (my latitude) spring/fall; 60 winter. It makes quite a difference to the power output. Something not fully reflected in the stats as, of course, I could be making considerably more power if I had a place to put it.

That's about 1.4 Mwh a year. Pretty good!

thx. I'm over 3 megawatts now. Only took me 5 years. ha ha ha.

still. 3.8kw/day sure makes off grid easier. Can't wait to get the new battery pack.
