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!

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 am very excited about my solar and Tesla Powerwalls that have been installed at my home. The installation crew worked fabulously and efficiently. From the very beginning of the process, I have been pleased with every contact opportunity. The total time from my initial inquiry to approval from SRP to go online was only about 8 weeks. The process was very timely. Thank you Tesla!

We elected to go with Green Street Solar for our new house rather than the company our builder owns and recommended. The builder claimed their offer included a discount for $10K since we were building with them. However, Green Street Solar's price was 35% less. In addition, after doing some research on the panels offered, Green Street Solar uses the #1 ranked panel (& made in the U.S.A., Q-Cell. While the builder's company was offering a "knock-off" brand made in China. The system was installed on-time, within one-day, and we were up and running only a few days later. After 3 months, we are gathering far more energy than we are consuming. We are extremely happy about opur decision to go with Green Street Solar!

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!

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.

We had a 14kW system installed on our property. To go along with that, we ordered an $8,000 Tesla PowerWall. After six months of waiting on the PowerWall, I asked them to swap the PowerWall for more solar panels, which they agreed to do. That was over a year ago. Recently I discovered that Moxie is out of business and I'm paying $8,000 for production that I will never receive. I am not happy. I thought I'd done my research before choosing Moxie but in the end I got burned.
