Summary of Delaware solar incentives 2021
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. There’s a cap of 6 kilowatts (about 20 average solar panels), and that grant has a maximum value of $5,000. 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!

Federal solar investment tax credit
The federal solar investment tax credit will have the biggest impact on the cost you will face to go solar in Delaware
This perk is commonly known as the ITC, short for “Investment Tax Credit”. If you install your photovoltaic system in 2020, the federal tax credit is 26% of the cost of your solar panel system. This is 26% 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 26% = $5,200.
The federal tax credit falls to 22% at the end of 2022.
Net energy metering in Delaware
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.
Delaware solar rebates
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 $600 per kilowatt (kW), up to a maximum amount of $5,000 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.
Solar SRECs in Delaware
Delaware has a strong RPS, mandating 25% renewable energy by 2025-2026 (compliance years run from June to May). The current minimum level of renewable energy is 13% of total retail electric sales. That requirement will raise by 1% per year through 2025-2026. 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.
Delaware has carved out 3.5% of it’s ambitious state renewable energy standard to come from distributed solar generation, like panels on your rooftop. That’s a strong move. Coupled with this requirement is an incentive which paid homeowners $32 per SREC generated by home solar panels last year. If that rate continues, the amount works out to about $250 annually over the 20 years. Solid.

We looked online for 4 and 5 star solar installers after reviewing available online information about residential solar. Paradise Energy Solutions was the only company to quickly respond to my call and send a rep to our home to discuss everything they do, how and what kind of panels to install, and answer any other questions. Chris Roach was the rep. Very nice and knew everything about the whole Paradise process. It was very easy to make the choice to go ahead after speaking with Chris. We heard from Andrew next in a timely fashion. He came to the house to look at the inside attic structure and explained that his design would be checked by a company engineer to ensure structural strength. After the engineering response was delivered, Andy discussed the next phase (installation) and answered our questions about the process. Brett, Zane and Jeff came out to do the installation of the panels and hook-up into our home breaker box. All were very knowledgeable and took the time to do things correctly. Again, everyone was very nice and continued to answer any questions. Andy and Jeff were both involved with the final permit/approvals to get our system linked with the city utilities. The entire process was done very courteously and professionally. The price was in line with our expected estimate. The company is totally client-oriented, and we will not hesitate to recommend Paradise Energy Solutions to anyone who asks about our solar installation. We have already given info to a family member. We want to be an example in our community for solar power and its benefits. Paradise Energy Solutions is the perfect choice to install yours.

Seems it may pay for itself after 10 years or so. I had an electric bill that was approx half what it regularly was, but that was before the upgraded meter was installed. Since that was installed, it has been running in reverse more than forward, so that is a good sign. The panel installation looks good as well.

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.
