You can see the old panels sticking up on the left, and we’re sitting on some of the new panels, which continue on the lower roof on the right.
These panels were purchased with the assistance of a USDA Rural Energy for America Program (REAP) 25% grant:
Eligible projects include those that derive energy from a wind, solar, biomass, or geothermal source, or hydrogen derived from biomass or water using wind, solar, or geothermal energy sources.The REAP program will probably be renewed this year, so if you have a farm, you could apply.
We also applied for and got a U.S. Treasury 30% grant from the 1603 Program: Payments for Specified Energy Property in Lieu of Tax Credits. That program was funded by the The American Recovery and Reinvestment Act of 2009 (Recovery Act).
Finally, there is the Georgia Environmental Finance Authority (GEFA) 35% Clean Energy Property Tax Credit, which will apply in parts over four years.
That all adds up to 90% covered by grants and tax credits, which is a pretty good deal.
Now that remaining 10% is still a significant amount; like the price of a small car. But in 7-15 years (how long it will take to pay off this system, depending on how you figure it), what would the value of a car be? Much less than when you bought it. Meanwhile, these solar panels will be generating almost as much power as they are now, and they will continue to generate for at least a decade more, probably much more.
The big missing piece is up-front financing. For more on that, see other blog post.
Meanwhile, we have here on our workshop roof a proof of concept, operational right now.
The little dogs wanted to know what we were doing on the roof:
