I just went and look at the NC regulations and I DID NOT see a requirement for the installation to be done by a certified contractor or words to that effect. The requirement might be there but I could not find it. The law changed quite a bit on Jan 1, 2010 so the requirement could have been removed.
Geothermal now qualifies for a tax credit. :thumbsup:
We put in energy efficient blinds this year. Some blinds could get a tax credit but you had to get just the right ones. After looking at brands, models, and crunching the numbers we did NOT use the blind models that got the tax credit. The tax credit blinds were priced to a point that we could buy less expensive models and not have to file paper work to get our money back. The blinds we bought did keep the rooms warmer by a couple of degrees and it was noticeable.
One has to look at the details to get the tax credit. You might very well be able to get energy efficient "stuff" cheaper than following the regulations to get a tax credit.
In NC you can get 35% of the cost back as a tax credit. Sounds good and it is but there is a but. There is another limit on the tax credit. One can only get 50% of you state tax bill back in a given year. In other words if your NC state tax bill was $1,000 and you spend $10,000 on a PV system you COULD get up to $3,500 back. But since your tax bill is $1,000 you only get $500 back. Not $3,500.
You can take another five years to get as much of the $3,500 back but if your tax bill stays at $1,000 a year you will only get 6*$500 or $3,000 back not the full $3,500.
The details in the regulations to get the rebate are important.
