There can be solar tax credits and incentives available at the federal, state and local levels. The calculator above will show you the value of all incentives your home is eligible for.
Delmarva Power now offers a nice solar rebate program called a Green Energy Grant if you’re looking to install solar on your home in Delaware, with a maximum value of $6,000. Even if you’re not a Delmarva customer, DEC and DEMEC offer their own similar solar rebate programs. Not too shabby!
Delaware has also carved out 3.5% of it’s ambitious state renewable energy standard to come from distributed solar generation by 2027, like panels on your rooftop. That’s a strong move.
Coupled with this requirement is an incentive which pays homeowners $32 per Solar Renewable Energy Credit (SREC) generated by home solar panels (if your installer is savvy enough to claim them on your behalf). This works out to about $250 annually over the 20 years. Solid. Read on to learn more about how all the programs for home solar work in Delaware!
Learn what solar incentives are available to Delaware homeowners
See what Delaware solar incentives you qualify for based on your utility company and city
Find out how much these incentives and/or Delaware solar tax credits will reduce your cost to go solar and add batteries
The federal solar investment tax credit will have the biggest impact on the cost you will face to go solar in Delaware
If you install your photovoltaic system before the end of 2032, the federal tax credit is 30% of the cost of your solar panel system. This is 30% off the entire cost of the system including equipment, labor, and permitting.
Example: If your solar energy system costs $20,000, your federal solar tax credit would be $20,000 x 30% = $6,000.
The federal tax credit falls to 26% starting in 2033.
With net metering in some states, you get full retail rate credit for the amount of electricity you send back into the grid with your solar panels.
Net Metering requires your utility to monitor how much energy your solar power system produces and how much energy you actually consume to make sure you get credit for the surplus.
Delaware’s net metering law is straightforward and pretty much perfect. Any net excess generation (i.e. any surplus electricity) you produce is applied to your next bill as a credit at the full retail rate.
If you run a surplus for a full 12-month period you may elect to have the electric company cut you a check for the surplus, again at the full retail rate. Note, however, that nothing in the net metering law requires you to request the check. If it’s easier for you, you can just keep the credit rolling over onto your bill indefinitely.
Delmarva Power, DEMEC and Delaware Electric Cooperative all offer solar rebate programs.
If you’re lucky enough to be a Delmarva Power customer, you can qualify for a Green Energy Grant to go solar. The grant pays out $700 per kilowatt (kW), up to a maximum amount of $6,000 for your home solar installation! For example, on an average sized 6kW system, you can expect a rebate of $3,600.
The DEMEC green energy program rebate pays out $1,000 per kW, up to a maximum of $3,500. You’d max out that incentive with a small-ish 3.5kW system.
The Delaware Electric Cooperative’s green energy rebate pays out $500 per kW, up to a maximum of $2,500. So, to get maximum credit, you’d need to install a 5kW system.
Delaware has a strong RPS, mandating 40% renewable energy by 2035 (compliance years run from June to May). As part of that 40%, the state also has a specific target for solar electricity generation (called a "solar carve-out"), with an ultimate goal of 10% of all electricity sales coming from solar. The current minimum level of renewable energy is 22% of total retail electric sales, with 2.75% coming specifically from solar.
Those requirements will raise a little each year until 2035. Delaware’s RPS is critical to strong renewable energy policy. Utility companies aren't really all that gung-ho about you producing your own power. After all, it costs them money when you use less of their electricity. They also don’t naturally want to give you big payments for energy you're feeding back into the grid. The main reason the utilities are aiding your transition to lower electric bills and offering you incentives to put solar on your roof is because the state forces them to. If the utilities don't hit their RPS numbers, they have to pay large fees back to the state. So, instead they’re willing to pay you for your solar renewable energy certificates (SRECs) that your home solar panels generate. By owning those, they can meet their RPS goals more easily and avoid alternative compliance fees.
In Delware, distribution utilities purchase SRECs from system owners on 20-year contracts. Each year, the SRECDelaware Program opens a competetive bidding process for SRECs. In 2021, the average purchase price of a Tier 1 SREC (from systems less than 50 kW) was $26.50. With a typical-sized system in Delwarae generating around 8 SRECs per year, that price works out to a payment of $212 per year, or $4,240 over the 20-year contract term. Not bad!
To sign up to sell your SRECs begin by, getting solar quotes and talking to installers about your options.

From the beginning, I knew exactly what to expect and when to expect it. I felt guided and supported through each step of the process and if there was any adversity, we worked together to find the solution that was best for us both. My voice was heard and appreciated, immediately reciprocated with honesty and integrity. The high quality of work and attention to detail shown was nothing short of exceptional. I know this because I work in commercial telecommunication construction and saw the same efficient and strategic professional processes you would expect to see. I'm hard to impress and from the pre walk, to the electricians to the installation team, all showed nothing but courteous, sincere, and experienced technical abilities, capabilities, each driven to be safe and supportive. They earned their 5 stars, and I would recommend them to anyone that wants to work with a high-quality and devoted team providing a un-matched product and service that is Solar Energy World. The hardworking and professional team include but are not limited to Ali and Jeremy on the electrical side and PV installers Mike, Roman, Mark, Luka, and Keith. The pride and effort they showed in their work speaks volumes and deserves the recognition.

No issues from technical side, but after-sales customer support is not professional. Our Zantrex/Snider box stopped inverting during real-life grid outages. Standard Solar sent a technician who couldn't find or fix the problem, but sent $760 bill without explanation or warning. We had to deal with Snider on our own, and Standard Solar had problem to find proof of purchase. When they send technician to the house, they charge $92/hour, including transportation, on-site downloading manufacturer's instructions, etc. Not the level of service one would expect.

I am very pleased with the finished product. The process can get very frustrating. It requires a lot of patience and a great outfit like Clear Horizon to make it all come together. I have to say that these guys are very professional and hard working. They make sure that you are completely satisfied. Thank you for making a dream turn into reality. It was a pleasure doing business with them!

SunnyMac did have an attractive offer, as I was directed to them by using the EnergyPal service. My EnergyPal advisor pushed to have proceed with a Site Survey to continue moving forward, while waiting for Tesla to come out and take a look. During this period, we had five companies out to take a look and give us quotes (none of them with a fee - more on this below). With SunnyMac however, they sent over an agreement for a "deposit," which did not say nonrefundable, which was due for the site survey. I spoke with my EnergyPal advisor, Caleb Siu who told me the deposit was only owed, if I had SunnyMac submit permits on my behalf, so I agreed to the site visit. Well, my advisor was wrong. I am now receiving $1250 invoices from SunnyMac for the site survey and for "designing" my system, although I had to tell them exactly where to put all of the panels (based on other companies visits), as their proposed designs (poor computer generated models) were terrible and would have been terribly inefficient. Anyway, do not have anyone come to your home from SunnyMac unless you are 100% certain you are going to go with them, or they will send you a trumped up bill and threaten collections.
