Last Chance To Get a Solar Rebate in Washington DC?

In the last week, I had four different friends ask me what they needed to do to go solar.  I thought it was a good time to send out an update on the DC Rebate Program and the economics of solar.  Here are the basics.

Getting a Solar Rebate in Washington DC
  • The District of Columbia's original 4-year Renewable Energy Incentive Program (REIP) came to an end in 2012.  Those that were able to get in on this program got a very sizable rebate at the beginning of the program, and those at the end received a good rebate, but at about half the amount originally offered.
  • DC has decided to continue with a rebate program in 2013 (which also includes solar thermal), but again, the rebate amounts have been cut substantially.
  • Recent drops in solar panel prices have somewhat offset the drop in the DC rebate amount.
  • The market for solar renewable energy credits (sRECS) remains strong in DC, meaning that the combination of sRECs, the available 30% Federal tax credit and the DC rebate continues to make solar an attractive investment. 
  • All signs seem to point to the gradual phase-out of rebates as panel prices fall and solar comes much closer to grid parity (when solar generation costs are equal to other non-renewable sources).
  • Even if you have not completely decided to go solar, you should put your name on the waiting list for the DC Rebate program.  You can decline later if you decide not to move ahead.  When applying for the rebate, if you have not yet selected a contractor, you can indicate on the application that you are with the DC Solar United Neighborhood (DC SUN) cooperative.  See for more about going solar, finding a contractor and applying for a DC Rebate.
  • Most homeowners are putting on systems that are in the range of 3-6kW.  Installed systems can be found below $4 per watt.
  • A very simplified cost scenario for a 4kW system goes as follows -- $16,000 system cost - which would receive a $2,000 DC Rebate, a $4,800 Federal Tax credit, and more than $4,200 in sRECs.  Considering rebates and subsidies, out of pocket expenses fall to $5,000.  Your electricity bill would be reduced by more than $600 per year.  Under this scenario, your break even point would be about 8 years.  Finding a contractor a bit cheaper than $4 per watt, and selling your sRECs on a quarterly basis (rather than an up front lump sum) might shave that break even point down to about 5 years.
  • Some companies will offer leases if you are not able to pay for or finance your system. 
More About the DC Rebate

Looking back out the DC Rebate program, it was a bumpy road in regard many aspects of the program.  Solar advocates in DC had to keep fighting each year to ensure that dedicated funds were not raided for other purposes.  However, in the end, more than 700 projects were funded by the DC Department of Environment (a small amount of additional rebates, not included in the table below, were issued by the DC Sustainable Energy Utility).

It looks like 2013 might turn out to be the highest year in regard to systems receiving rebates.  There are currently, 386 people on the waiting list for photovoltaic systems (link).  DC indicated that rebate offers would begin going out in February 2013, so some people on the waiting list may be getting approval letters.  The funding levels are as follows: 

For calendar year 2013, DDOE will offer  the following solar incentives:
·         $0.50/watt for photovoltaic systems, with a cap of  $10,000 (equivalent to a 20kW)
·         20% of total system cost up to $2,000 for residential thermal and,
·         20% of total system cost up to $6,000 for non-residential thermal systems

The REIP was given $1 million in the Sustainable DC Act of 2012, so assuming an average rebate of $2,500 per system, there will be 400 rebates available.  Assuming there is no other funding available, now would be a good time to get on the Waiting List.

Lastly, if you live in MD, you may be able to get a state rebate.  sREC prices in MD are much lower than in DC.  If you are in VA, solar incentives are very poor, but you can ask the governor to fix that using this petition.

  1. Well, it's really a great chance for the residents of Washington DC to get some rebate and save money on solar panels. Also, it is a great way to promote an encourage people to utilise solar power more and more.

  2. Sounds great and a blessing for Washington DC residents, such rebates can encourage more savings and use of solar energy.

  3. I don't live in DC but where I am having just a 200 watt solar panel can make a world of difference in savings. I have honestly loved it. It is just the initial investment that you have to get over.

  4. Solar Energy is the Best.

  5. Hi, nice post. Well what can I say is that these is an interesting and very informative topic about solar energy tax credits. Thanks for sharing your ideas, its not just entertaining but also gives your reader knowledge. Good blogs style too, Cheers!

  7. Solar power projects are becoming increasingly popular as the world begins to notice the serious problems that comes with burning fossil fuels.

  8. If the housing unit at the time of the sale do not have a heating system, there is no obligation to draw up an Epc. In that case, no mention of the notary is required. If valid proof is here accepted an autographed agreement between buyer and seller which states that no heating is present at the time of the offering for sale of the property.

  9. The rate with which the consumption of fossil fuel is going, at such time installing renewable energy resources like this could be a good decision. But the fact is that these resources are not being used to their full potential.

  15. Thank you so much for posting. I have been looking for something like panels for schools

  16. I like that there is some incentive to convert to solar power. As an economist, I understand that people are motivated by incentives and they won't do anything if they don't have some sort of incentive that outweighs their costs. That being said, there is still much more to do to become more energy efficient and independent.

  17. Issues surrounding solar thermal can never be over analyzed. In depth analysis of solar thermal can be an enriching experience. While much has been written on its influence on contemporary living, several of todays most brilliant minds seem incapable of recognizing its increasing relevance to understanding future generations. Often it is seen as both a help and a hindrance to global commercial enterprises, many of whom fail to comprehend the full scope of solar thermal. Hold onto your hats as we begin a journey into solar thermal.

  22. Wow, its a really cool plan for use this kind of energy here in Washington Dc. I will see if it is use here nowadays while in mine
