The number of people going solar in the First State has been increasing recently, thanks to Delaware solar incentives and other tax credits that reduce the cost of solar panels in Delaware.

Although Delaware generates most of its electricity (86%) from natural gas, a new law requires utility firms to derive 40 percent of their power from renewables by 2035 and harness 10 percent of renewable energy from the sun.1

Since your roof can make all the difference, Delaware has various incentives for residence owners to go green and increase the current number from 5%.

In fact, based on the state’s renewable framework, Delaware solar incentives and tax credits, grants and more, residents and businesses in the First State can significantly reduce the cost of solar panels in Delaware.

How Much Are Solar Panels in Delaware?

The average cost of solar panels in Delaware is anywhere from $10,922-$14,778.

Moreover, installing a solar panel will cost you $2.18-$2.96 based on the dollar for every Watt.2

At that point, Delaware can be touted as one of the best states to go solar due to the availability of solar rebates and an effective net metering policy.

Another essential computation to note before going solar is the repayment period. As a clean energy-conscious resident or business entity, you should calculate the amount of time it would take to recoup your upfront costs through the money you save on your electrical energy.

It takes approximately 8.95 years to repay for a solar system installation in Delaware, depending on the system you install.

In addition, Delaware residents are faced with the choice of how to repay a solar system. The beauty, however, is that many financial options exist that allow willing Delawareans to afford solar system installations.

However, you don’t have to go solar using your hard-earned cash with available financing options, including solar loans and leases.

For instance, the clean energy tax credit can save you thirty percent on your taxes for deploying a clean energy system on your rooftop that harnesses energy from the sun.

You can also get extra rebates and save big time in Delaware after rolling out a solar system with the help of Net Metering. What happens is that you’ll get rebates from utility firms in Delaware, which reduces the cost of panels.

Understanding Solar Renewable Energy Credits & Net Metering

Solar panels are pretty effective in Delaware. Solar systems in the First State generate more solar power during peak sunny days, which is way above what you need for domestic usage.3

On the other hand, net Metering will help you earn from extra units fed into the grid as outlined in Bill 4727.

Delaware authorities to provide financial aid to anyone intending to go solar. As a homeowner, you can access rebates to facilitate cheap installations of solar panels on your rooftop.4

Don’t forget that the rebate amount depends on the size of your clean energy system. Solar systems about 15kW in size qualify for a $0.05/w rebate, which augments your savings.

Delaware Solar Incentives Can Reduce the Cost of Solar Panels

The state of Delaware has a solar incentive scheme funded by the state authorities to provide financial aid to anyone intending to go solar. As a homeowner, you can access rebates to facilitate cheap installations of solar panels on your rooftop.4

Don’t forget that the rebate amount depends on the size of your clean energy system. Solar systems about 15kW in size qualify for a $0.05/w rebate, which augments your savings.

The net metering guidelines in Delaware are user-friendly.

It allows you to sell off electricity in line with article 4727 of the state laws.

Delaware Solar Incentives Available for Residents

Delaware has a number of programs available to help you install solar panels in your home.

In addition to the federal solar investment tax credit, the state provides options for residents who own property and businesses that switch to solar power.

The following programs and financing options make solar energy a great investment.

Delaware Green Energy Program

This is a three-phase grant funded by the D.E. Energy office utility firms. Some of these firms provide an optimum of $6,000 rebates to assist residents in rolling out solar on their premises.

However, this rebate can drop depending on the number of people applying.

You’ll also get $0.50 for the first 5kW as well as $0.20 when it goes beyond that threshold.5 There’s a twenty percent rebate on solar thermal and fuel cell installation expenses.

A local state utility firm incentivizes residents an equivalent of $1.00/w for the first 5kW and $0.05 for any extra power above the threshold.

Net Metering in Delaware

Far from Net Metering, Delaware is one of the best solar programs that enables you to make money from the extra units you produce.

In this age of automation, you simply sit back as the system works for you.

Solar Renewable Energy Certificates (SRECs)

Apart from net Metering, Delaware has a robust solar program allowing residents who have rolled out P.V. panels to earn money from the additional energy they produce back to the grid.

You can determine your power output upon installation by getting help from competent service providers. Besides, part of the solar system includes a device that handles all your sales.

Federal Tax Credits for Delaware Residents

Who said you’re limited to local or state rebates amid competing choices? As an American citizen who honors your tax obligation without exception, you can take advantage of the federal program courtesy of the investment tax credit (ITC).

Nonetheless, unless you own a home/property, you may not be eligible for the fed credit. You also are eligible for the federal solar tax credit after buying the solar system in cash or through a solar loan.

However, you can only reclaim the fed credit when filing your tax return during that tax year. With a fed credit, you’ll get a 30% off the solar system costs.

Delaware solar incentives are available for residents and business establishments who wish to go solar at a discount.16

How To Pay for Solar Panel Installation in Delaware

Are you operating on a shoestring budget and wondering how you’d pay for your solar panel installation?

If this explains your predicaments, don’t fret! You can use and pay for your solar panel installation in several ways.6

Graphic image of how to pay for solar panel installation in Delaware using cash payment, lease or purchase agreement, or solar loans.

And all these options differ; you must opt for one that suits your needs.

Cash Payment

While the majority of Delaware residents and businesses would want to buy solar panels in cash terms, this is never the case. However, this is one of the options, yet it works for a few who can afford it.

Cash payment does not attract interest or hidden costs, which is a major strength of it. The credit score becomes a thing of the past since it does not affect your purchase.

Just because you’re cash trapped now does not mean your journey to becoming solar will hit a snag. Many options exist out there.

But just in case you harbor futuristic plans of deploying a solar system on your rooftop, hive money into a savings account to enable you to meet upfront costs and enjoy colossal savings toward the system over time.

Solar Loans

You can also opt for a solar loan from solar dealerships and 3rd financial entities. However, before you settle for a loan, evaluate it against interest rates and hidden fees that can make it cost over the years.

You can also apply for a personal loan, home equity loan, or home equity credit to fund your solar system at reasonable interest rates. But such loans have risks too.

A default on your payments can be disastrous as you risk losing your home.

Lease or Purchase Agreement

Solar companies have devised ingenious ways to bring down the cost of solar panels in Delaware to enable you to install solar panels, including power purchase agreements and leases.

When you opt for a lease, you will utilize the system to generate solar energy without necessarily owning it.

On the other hand, a power purchase agreement (PPP) would enable you to purchase solar power harnessed from the system for domestic consumption.

The cost you pay is essentially lower than what you get from utility firms in your area.7

Solar Panel Cost Calculator: How To Calculate Solar Panel Installation Cost Delaware)

Want to install a solar panel on your rooftop? It would help if you had a solar panel cost calculator. Solar panel cost calculator remains critical before you invest in a green and clean future.

How do you calculate the cost of solar panel installation in Delaware? You can use an online calculator to calculate the amount required to roll out a solar energy system.

What Determines Solar Panel Installation Cost in Delaware? (Factors Influencing Cost of Solar Panels in Delaware)

The cost to install a solar panel depends on many factors, including system size, panel brand, and quality. Thus, a bigger solar panel will be more costly than a small one, although the price drop as the unit size increases.8

Again, different solar companies have different installation costs, with premium firms or firms with more reviews charging more than startups. Integrating into the grid comes at a fee as well, although insignificant, and this should be put into consideration as well.

Factors To Consider Before Solar Panel Installation

Essential considerations for solar panel installation include the following:

The State of Your Roof

Before deploying a solar system, ensure your rooftop is in perfect condition.

Usually, a reputable solar company will inspect your roof before commencing with installations.

The solar company will assess the roof against damages, pitch and angle, and the free space. Based on the U.S. Department of Energy, a 15-40 degree roof facing southwards is often the best for solar systems.

Homeowners Association Guidelines

Ensure you conform to the guidelines provided by HOA before you proceed with installations.

While HOAs in Delaware cannot in any way outlaw P.V. panels, they can impose limitations.

Location (Delaware Peak Sunlight Hours Each Day)

The amount of sun you’re able to harness during peak hours determines how efficiently your solar panel runs.

Map of the state of Delaware with each county colored to show the daily peak sun hours in each Delaware county ranging from 4.27 to 4.35 daily hours of sunlight.

As a cloudy state, the First State receives 4.23 peak hours of sunlight in a day.


While you can deploy your solar system if you live in a rented property, you can take advantage of community solar schemes, which allow you to tap solar energy produced by solar farms or firms.

Insurance Cover

Insurance firms cover solar systems; if this is the case, you should add your devices to your homeowner’s policy.

Can You Get Free Solar Panels Delaware?

Why are solar panels so expensive in Delaware, and yet we’ve got free solar panels around? Well, free can be expensive in every sense.

But that said, a combination of tax rebates and incentives will bring down the cost of solar panels in Delaware and make it appear like free solar panels.

Every year programs get implemented to promote the adoption of solar energy by reducing the cost of solar in Delaware.7 The state focuses on taping green energy by incentivizing businesses and homeowners to install solar panels.

Solar panels are a good investment in reducing carbon footprint and energy bills, but you should consider various factors, including.

Energy Consumption

The sizing of solar panels relies on monthly electricity usage. The size can be influenced by electricity consumption and the capacity of the system to cut down energy costs.

If you’re a high-energy consumer, the more valuable the panels. As a result, monitor for your energy consumption to ensure you consume approximately 500 kW monthly.

Pie chart showing Delaware renewable energy consumption including Delaware wind energy, biomass energy, geothermal energy, hydroelectric energy and solar energy in the state of Delaware for 2022.

On average, a homeowner in Delaware uses about 932 kW per month, indicating that you’ll save electricity bills when installing a solar system.

Payback Period

The benefits of solar installation are maximizing savings on electricity costs and reducing upfront costs.9 Therefore, the time you take to pay for your solar panels is used to establish how much you’ll save.

In Delaware, the average payback time frame is 12 years. In this case, you should pay off your solar panels before 12 years to enjoy a high return on investment.

Amount of Sunlight

Solar panels generate energy from the sun. Thus, the area’s sunlight is a factor to consider when installing solar. Delaware receives below-average sunny days throughout the year.

In this regard, you might assess the shading of your roof, considerable shading will minimize the value of your solar panels by affecting efficiency and savings in the long run.

Want to know how to get solar panels for free? You can try the Weatherization Assistance Program (W.A.), a low and middle-income initiative that enables Delaware residents to install solar panels without any hustle.

Delaware Solar Tax Credit

Want to reduce the cost of solar panels in Delaware and go green and clean? The choice is in your hands, amidst rebates and tax credits available.

Moreover, you also get to optimize the net metering policy to cash in on the excessive energy you send to the grid.

Nonetheless, you need to understand that Delaware doesn’t have local or state taxes, which implies that property owners don’t have to pay sales tax when purchasing and installing solar. This suggests savings for businesses and homeowners.

But there is no exemption on property tax; thus, you must pay value-added on the property for switching to green energy. You can also exploit solar grants and loans offered by state utility companies.

Solar Energy Delaware (Factors To Consider Before You Harness Solar Energy From the Sun)

With various solar panel installation firms in Delaware, solar energy represents the future of the First State. However, if you’re switching to green energy, it is essential to choose a qualified installer to meet your solar needs for significant savings.

For solar energy adoption,10 you should consider the following:


Specifically, it costs roughly $24,510 for solar energy in Delaware. This cost includes the per Watt for solar panels at $2.58 compared to $2.66 nationally.


Remember to ask the service provider for indemnity against storms common in Delaware.

Company’s Sustainability

Subcontract services from a reputable firm with at least five years in service, and you’ll get value for your money.

Solar Panels

It’s also necessary to consider installers offering efficient solar panels. The performance of your system determines the energy it generates.

This is critical when converting to solar energy in Delaware because of the high energy consumption and few sunny days throughout the year.

Based on these factors, you must buy efficient solar panels since they are appropriate and can assist you in saving on electricity costs.

Delaware Solar Program (What You Need To Know About Delaware Solar Rebates)

Delaware has various solar programs and rebates that make it easy to go solar.

How about property value? Does solar increase home value? Yes, it does.

Solar energy increases property value by maximizing your electricity savings, paying your system, increasing your home’s value, and decreasing your carbon footprint.

Okay, here’s what you should know about local rebates.


Even though Deleware is positioned 41 across the U.S. with the number of installed solar systems, it has a good solar program. For example, the First State has a robust alternative energy credit called the SREC that incentivizes Delawareans to invest in renewable energy and earn money in line with Bill 4727 for selling unused energy.

  • Use Delaware’s SREC website and signup.
  • Follow the prompts on the screen to apply. Ensure you’ve system and installer details.
  • Once you get approval, your solar system energy production will be monitored, and credits will be sold to the utility company.

As much as SREC is competitive, it is a good solar program Delaware uses to foster and motivate residents towards embracing green energy.

In addition, SREC presents businesses and homeowners with an opportunity to increase the value of their solar system to earn credits while maximizing savings.5

Earnings are not assured, so you must wait 20 years to earn credit.

Net Metering

The Net Metering is a popular solar incentive ensuring you sell excess power to the grid.11 Delaware has an effective net metering law, allowing residents with solar systems to sell energy under Bill 4727.

Interestingly, net Metering Delaware will enable you to sell excess energy at retail cost rather than a wholesale rate so that you save on generating renewable solar energy.

This solar program guarantees that you increase energy savings in the long run. Again, it decreases your payback period, making your solar panels valuable.

Nonetheless, under the net metering policy, you can use the credit in the future, especially if your energy consumption is higher than your solar system generates monthly.

As such, over-generation in summer can compensate for high consumption and low generation during winter.

But the net metering laws are rapidly changing across the country due to the widespread adoption of solar energy and attainment of Renewable Portfolio Standard (RPS) goals.

In certain regions, net Metering puts significant pressure on the grid contributing to power interruptions, which reduces eligibility for net energy metering.

Therefore, registering for net Metering in Delaware is not automated; however, installers in your region can help you register your solar system.

Follow these steps to register and capitalize on net energy metering credits;

  • Ensure you have a properly installed. The bi-directional meter is preferred for net Metering; your installer should check to approve.
  • Check with your solar installation firm to ensure a representative will register you into Delaware’s net metering initiative.
  • Continue with installation
  • Monitor your energy bills for a few months to ensure your credits are amassing.

Basically, net Metering is a valuable solar program, particularly in Delaware, where energy is used higher than the national average.

Local Solar Rebates

The local governments and utility firms in Delaware incentivize Delawareans towards solar adoption. For instance, the local utility firms offer varying rebates; some offer  $0.70/Watt for a solar size of 9 kWh, capped at $6,000.5

Furthermore, other utility companies offer $0.50 to $0.20/Watt for $2,000 for a system size of 5 kWh. Unlike solar loans, local grant and tax credit offers rebates for customers who have adopted solar, geothermal, and wind energy.12

The rebates depend on the system size; for example, it offers $1/watt for 5 kW and $0.5 /watt extra kW. On average, DEME gives roughly $7,250 in rebates for a system size of 9.5 kW.

Federal Solar Investment Tax Credit (ITC)

Delawareans can also claim solar rebates from the government solar investment tax credit.13 The credit pays for 30% of the cost of the system, including required equipment, installation cost, and permit.

Delaware Solar Program Type of Incentive Description Ending Date Amount
FITC Federal Government Provides 30% of the total cost of the solar system on taxable income December 31, 2023 $7,353
SREC State Government SREC allows Delawareans to earn credits based on the solar generated. The credits can also be sold to utility firms to earn profit None $2,640
Net Metering Local The program enables Delawareans to earn credit based on the energy produced. Moreover, credits can offset future power bills. Continuously provided the solar panels generate energy The amount is determined by solar system size and energy demands
Local Incentives Local Local governments and energy organizations offer credits and rebates Depends on the type of incentive. The amount is based on the solar system, the type of incentive size, and energy bills.

Are Solar Panels Worth It in Delaware Owing to the Federal Solar Tax Credit?

Are solar panels worth it in Delaware? Of course, especially with federal solar tax credits and local rebates. The truth is federal solar tax incentives have increased the adoption of solar renewable energy in Delaware.15

If you’re interested in converting to solar energy, you can capitalize on the federal solar tax credit and get 30% off the cost of the solar panel. However, the 30% is applied one year after installing the solar system applied to your income tax liability.5

While the credit is capped at 26% in 2023, it is scheduled to reduce to 26% in 2026 and 22% in 2023, and no credit for solar systems installed from 2035.14 Therefore, take advantage of the federal tax credit and save on your solar installation.

And how does the solar tax credit work if I don’t owe taxes? When you don’t owe the federal government any taxes the first year, you can always recoup the following year.

You need to know that the credit limit will stay at 26% until the end of 2023.14 This means you can now take advantage of the fed tax credit and light up your home with clean energy.

Now that I owe taxes, how does the solar tax credit work if I don’t owe taxes? Nonetheless, a pertinent requirement would be ensuring your solar panel system has the capacity to generate 9.5kW to offset energy costs.15

What Is the Difference Between Federal Solar Tax Credits and Rebate Credits?

The difference between the two stems from the application process. Federal solar tax credit is a tax credit you claim when you file your taxes, and it is usually 30% of the initial cost of your solar panel.

That is, if you owe $12,000 in taxes and installed a solar system amounting to $24,000, then the amount owed in taxes will be reduced by $7,200, which implies you’ll pay $4,800 as your tax.

How Can I Claim the Federal Solar Tax Credit?

Claiming federal energy credits involves a simple procedure outlined below;

  1.  Go to the IRS website and download for 5695
  2. Then, fill out the form with information regarding the location of the system, your address, size, and cost, and contact details of the company that installed the system.
  3. Remember to include Form 5695 with your tax documents.17 But you can also use Turbo Tax software to follow the prompts about solar energy.
