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.

I would like to thank Bethany Fuller for helping me out. I couldn’t under stand why my production rates were not adding up properly. I was told I don’t have a consumption meter and the energy that my house was was in accurate She is a very intelligent lady and very nice to talk with. Thanks Bethany again for Your help.

Bel Air, Maryland - So, I have gotten 5 estimates for solar panels for my home. I decided to go with American sentry solar because the estimate process was straight forward, they answered all my questions and did a good job at explaining the County/State/Federal Solar incentives that would apply to my project (plus they are local to me). The project was quick and again straight forward. This is the timeline of my project: 09/22/23- Started the paperwork- contract/permit/Loan etc. 10/04/23- Site planning visit- (electric panel and roofing system inspection) 10/25/23- System Install – Took about 4 hours – (The crew was outstanding) 10/31/23- Local Government (County Permit Inspection) 11/15/23- Power Company updated power meter to be compatible with the system. 11/16/23- System in full Operation I like being able to see what the system is producing to include the system status and what each solar panel is producing with the Enphase enlighten App. Now the wait to see the effects to my energy bill begins and I will update in the future. Overall, I’m very happy with the whole project and would recommend the American sentry solar team.

We had CMI install our solar system several years ago and were very happy with the work and the system. Earlier this year we asked them to help us with a generator hookup. We had no problems until several weeks ago. We contacted CMI and they were able to correct the problem. We definately appreciate the overall quality of their install and their willingness to stand by their work to resolve any issues.

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.

What a great experience working with Clean Energy USA on my residential install. I would highly recommend this team to anyone looking to install solar. Everyone at Clean Energy USA was a pleasure to interact with and highly knowledgeable. As a new customer to solar I could not be more appreciative of the efficient and smooth process from sales, back office and intstallation.

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.

I have a solar panel system that was installed by wanex and it has rodent damage that was found by Sun power. The technician from Sun Power told me that I would not have had this damage had I been given the option of having a rodent guard system installed at the time of the installation. I at now at a loss of over $5000.00 over negligence on the contractors part. I had also asked the contractor to split the install on my garage roof because of the weight of the panels (over 40lbs.) each and since they did not listen to me at the time of the install my garage which is sitting on stone has since sunk into the ground on the side the panels are installed on and continues to sink. At this point we do not know what to do because these damages are not covered by homeowners insurance.
