Current Solar Costs in Delaware
If you’re wondering how much do solar panels cost in Delaware, you’re looking at $2.25 to $3.11 per watt before any incentives. The total cost to install solar panels depends on your system size, the equipment you choose, and how complex your installation ends up being.
Delaware Solar Panel Prices by System Size
| System Size | Cost Before Incentives | Cost After Federal Tax Credit | Monthly Savings | Annual Savings |
|---|---|---|---|---|
| 5 kW | $11,250 – $15,550 | $7,875 – $10,885 | $95 – $125 | $1,140 – $1,500 |
| 6 kW | $13,500 – $18,660 | $9,450 – $13,062 | $115 – $150 | $1,380 – $1,800 |
| 8 kW | $18,000 – $24,880 | $12,600 – $17,416 | $150 – $200 | $1,800 – $2,400 |
| 10 kW | $22,500 – $31,100 | $15,750 – $21,770 | $190 – $250 | $2,280 – $3,000 |
| Pricing Disclaimer: The solar panel prices shown are estimates based on data collected from online sources as of October 2025. Actual costs may vary based on your location, system specifications, and installer. | ||||
Most Delaware homes need an 8 to 9.5 kW system to cover their energy needs. The typical household here uses between 923 and 1,293 kWh monthly. With electricity rates sitting at 16.62 cents per kWh this October, you’re probably paying somewhere between $153 and $215 each month for power.
Here’s something important: the 30% federal solar tax credit disappears on December 31, 2025. Your residential solar panels need to be completely installed and running by that date if you want to claim it. We’re talking about saving over $6,000 on an average system, so the clock is ticking.
Delaware Solar Incentives and Programs
Solar incentives in Delaware can seriously cut down what you’ll pay for solar panel installation. Between federal, state, and utility programs, there’s real money on the table.
Federal Solar Investment Tax Credit (ITC)
The federal Residential Clean Energy Credit gives you back 30% of your total installation costs. Put $20,000 into a system, and you’ll get $6,000 back at tax time. But again—this ends December 31, 2025. After that, it’s gone for good.
Delaware Green Energy Program
Your utility company determines which rebate program you can access:
Delmarva Power Green Energy Grant
- 70 cents per watt for home systems
- Up to $6,000 back for residential installations
- Available if you’re a Delmarva customer anywhere in the state
Delaware Electric Cooperative (DEC)
- 35 cents per watt for your first 5 kW
- 20 cents per watt after that
- Caps at $2,000 for homes
Delaware Municipal Electric Corporation (DEMEC)
- Only available if you live in Newark
- $1 per watt for the first 5 kW
- 50 cents per watt for anything larger
- Maximum of $3,500
Solar Renewable Energy Certificates (SRECs)
Here’s a nice bonus—your system generates SRECs that you can actually sell for extra income:
- First 10 years: roughly $30 per SREC
- Years 11-25: about $10 per SREC
- You’ll probably make around $325 each year during the first decade
- Over 25 years, that adds up to approximately $4,600
If you install an 8 kW system, expect to generate about 1.35 SRECs per kilowatt each year.
Net Metering
Delaware’s net metering policy is one of the better ones you’ll find. When your panels produce more electricity than you’re using, the excess goes back to the grid and you get credited at the full retail rate:
- You can size your system up to 110% of what you used last year
- Credits roll over month to month
- They’re worth the same as what you’d pay the utility
- All Delaware utilities participate
- Any credits left at your billing anniversary just reset—no cash payout
Low-to-Moderate Income Solar Programs
If money’s tight, Delaware offers help:
- Qualifying low-income households can get free installations up to 4 kW
- Moderate-income families have access to solar loans
- Call the Energy Coordinating Agency at 302-504-6111 to see if you qualify
Additional Benefits
Delaware doesn’t charge sales tax on solar equipment, which helps. Just know that solar does increase your property value, and that means your property taxes will go up accordingly—there’s no exemption here.
Specific Considerations for Delaware Solar
Solar Irradiance and Climate Benefits
Delaware gets between 4.8 and 5.1 kWh/m²/day of solar radiation. Dover sees about 5.09 on average. You’ll get somewhere between 202 and 250 sunny days per year, which keeps your panels producing consistently through all four seasons.
Our moderate climate actually works in your favor. Unlike the scorching Southwest, Delaware’s temperatures help panels run more efficiently—they don’t like extreme heat. Yes, we get coastal humidity and the occasional storm, but modern panels handle Delaware weather just fine when they’re installed correctly.
The state’s pushing hard for renewables too. Delaware’s Renewable Portfolio Standard says 40% of our electricity needs to come from renewable sources by 2035, with 10% specifically from solar. That means the policy support and grid improvements will keep coming.
Permitting and Interconnection Process
Getting your system permitted and connected in Delaware is pretty straightforward:
Permitting Requirements:
- You’ll need a local building permit
- Any decent installer handles this paperwork for you
- Back in 2019, Delaware passed HB 65, which stops HOAs from blocking your solar installation
Interconnection Process:
- Your utility has to let you connect systems up to 25 kW for residential
- There’s a standard application they process
- You’ll need a final inspection before everything goes live
- Again, professional installers take care of coordinating with the utility
Timeline Expectations for Solar Installation
Knowing how long solar panel installation takes matters, especially with that December 31, 2025 federal tax credit deadline approaching fast.
Installation Timeline Breakdown
Phase 1: Consultation (1-2 weeks)
- Someone comes out to assess your property
- They’ll analyze your energy usage and design a system
- You’ll get quotes to compare
Phase 2: Contract and Financing (1-2 weeks)
- You sign the contract
- Financing gets arranged if you need it
- Final engineering design gets completed
Phase 3: Permitting (2-6 weeks)
- Building permit goes in
- Utility interconnection application gets filed
- Everything gets approved
Phase 4: Equipment Procurement (2-4 weeks)
- Your panels and equipment get ordered
- Delivery gets scheduled
Phase 5: Installation (1-5 days)
- Most home installations take 1 to 3 days
- They mount everything, run the wiring, set up the inverter
Phase 6: Inspection (1-3 weeks)
- Final inspections happen
- Utility gives the green light
- Your system goes live
Total Timeline: 2-4 Months
From your first meeting to flipping the switch, plan on 8 to 16 weeks for a home system.
Critical Timing for 2025
If you want that 30% federal tax credit before it vanishes:
- Right now in October, you should be getting quotes
- By early November, you need to have a contract signed
- Build in extra time for permit delays and installer schedules
Is It Worth Going Solar in Delaware?
Financial Returns
Are solar panels worth it in Delaware? Let’s look at the numbers:
Payback Period: 6 to 8 years typically
25-Year Savings: $25,000 to $50,000
ROI: Around 10-15% each year
Electricity rates hit 16.62¢/kWh this October, and they’re not going down. The cost of solar panels in Delaware, when you factor in the federal tax credit, state rebates, SREC income, and net metering, pencils out really well.
Property Value Impact
Your home’s value goes up about 4.1% when you add solar. For Delaware’s median home price of $375,000, that’s roughly $15,381 more when you sell. This only applies if you own the system—leased systems don’t add value.
Environmental Impact
An 8 kW system offsets:
- 10,000 to 12,000 pounds of CO₂ every year
- Same impact as planting 150 to 180 trees annually
- Direct contribution toward Delaware’s renewable energy targets
Energy Independence
Between the solar incentives and net metering, you get:
- Less reliance on the utility company
- Protection when electricity prices jump
- Reliable power production for 25 to 30+ years
Key Considerations
When does it make sense? Solar works best for Delaware homeowners who:
- Plan to stay put for at least 7 to 10 years
- Have a roof with decent sun exposure and minimal shade
- Can move before December 31, 2025 to grab that tax credit
- Have enough tax liability to actually use the federal credit
Financing Options
- Cash purchase: Gives you the best long-term value
- Solar loans: Zero down, you own the system, you get all the incentives
- Home equity loans: The interest might be tax-deductible
- Avoid leases/PPAs: You can’t claim the tax credits or rebates with these
Choosing a Solar Installer in Delaware
Who you choose to install your system affects both how much it costs to install solar panels and whether you’ll have problems down the road.
What to Look For:
- NABCEP certification is a good sign
- At least 5 to 10 years working in Delaware specifically
- Check their Google and SolarReviews.com ratings
- Get detailed quotes that break down the cost of solar panel installation
- Make sure warranties are solid—25 years on panels, 10-15 on inverters
- They should handle all the paperwork: permits, utility stuff, rebates, SREC enrollment
- Ask for references from past customers
Get Multiple Quotes
Talk to at least 3 to 5 installers so you can:
- Compare solar panels prices and what equipment they’re offering
- See how responsive they are
- Make sure you’re getting competitive rates on the cost of solar panels in Delaware
- Double-check their system sizing makes sense for your usage
Action Steps for 2025:
- Start requesting quotes from several installers now
- Compare what different companies are charging
- Get your contract signed by early November if you want to finish before year-end
- Confirm your installer will handle all the permit and incentive paperwork
- Make absolutely sure installation wraps up before December 31, 2025
Delaware’s got decent sun, strong net metering rules, a good SREC market, and utility rebates that make residential solar panels worth considering in 2025. But with the federal tax credit disappearing on December 31, 2025, this is your last shot at maximizing savings on the cost to install solar panels in Delaware.
How Much Can Solar Panels Save Me in Delaware?
Finding out how much you can save on solar in Delaware is not a straightforward answer. It depends on several factors, including the solar billing of your utility company, the size of a potential solar system on your roof, and your household’s energy consumption. While most solar installers will try to cover all your electricity needs, the actual savings will depend on your home’s unique conditions. To get a personal estimate of how much you could potentially save by going solar, fill out a simple form on our website, use Google’s Project Sunroof solar savings calculator, or consult with a couple of local solar installation companies for a personalized savings calculation.

Solar Financing Explained
You can pay for solar panels in a couple of ways:
- Cash
- Installer solar loans
- Personal loans
- Cash-out refinance or HELOC
- Solar Leases or Power Purchase Agreements (PPA)
First, there is a cash purchase, which in most cases provides the best price and long-term savings, but the upfront payment is not always what you can afford. If you want to own your solar panels and don’t have about $15,000 to $20,000 in the bank, you’ll have to choose solar panel financing.
You can consider a personal loan, a home equity line of credit, or a solar loan offered by the solar company. However, keep in mind that these loans come with interest and additional fees. Solar loans often are tied to dealer fees, which can increase the total cost of your solar system by 20% or more in exchange for a lower interest rate. To ensure you get the best possible deal, it is wise to compare the dealer fees and interest rates offered by different installers. This way, you can make an informed decision based on the most favorable terms available.
Some companies offer solar leases or PPAs that require zero upfront cost. But in such case, you don’t own solar panels and you are not eligible for any solar rebates or the federal tax credit. And, because you have to pay the solar company monthly, your total solar savings will be lower. Ask for detailed savings calculations from a solar installer to decide on the best option. In most cases, you will still be paying less for electricity.

How We Classify Solar Installers: What Matters Most?
What to Look for In a Solar Company
To ensure that you partner with a great provider that can meet your needs of going solar, look for the following:
– Make sure the solar installer has industry-standard certifications, such as those from the North American Board of Certified Energy Practitioners (NABCEP), indicating that they meet the gold standard in renewable energy installations. Also, verify if they are licensed, bonded, and insured for residential solar projects in your area. If subcontractors are involved, check their credentials as well.
– Prioritize installers with a proven track record in solar installations, ideally with at least 5+ years of experience. Ask about the number of systems they’ve installed and their project portfolio. A competent installer should openly discuss the solar panels, inverters, and batteries they use if they help to take advantage of local solar incentives and rebates, as well as warranty coverage specifics.
– Your installer should be forthcoming about the installation process and answer any questions you might have, like “How many solar panels will I need? Why?”, “Can you give me a detailed cost breakdown based on my energy consumption?”, “What solar panel brands do you install? Why?”, etc. They should also be transparent about their use of subcontractors, detailing their roles and how their work will be supervised.
– A preliminary evaluation of your roof’s condition is the groundwork. The installer should advise on necessary repairs to ensure it’s ready for solar panel installation and clarify responsibilities for any potential roof damage during the process. Discuss aesthetic concerns, such as the placement of solar panels around roof vents or the possibility of relocating vents for a more visually appealing setup.
– Check the installer’s reputation through online reviews and testimonials. They should be able to connect you with past customers who are willing to share their experiences. Personal recommendations from friends or neighbors who’ve gone solar can also be invaluable.
– Solar installation costs can vary widely, so obtaining multiple quotes is advisable. Experienced installers will adjust their offers to your home’s specifics—size, energy needs, etc. For an objective cost comparison, calculate the price per watt of the proposed system, giving you a standardized basis to evaluate different quotes.
Should You Choose a Local Solar Installer or a Big National Company?
Always choose a local solar company over a big national corporation. Small local companies that operate in a distinct local area are better than multi-state and national solar companies and large corporations. It’s the small local companies who get the best reviews on our website, and it’s the national multistate companies who get very poor reviews. Why so, you may ask?
Solar is a local service business, for the most part, and it is extremely difficult to run a solar company and offer good customer service to many locations from a central office.
Local ones have a community connection, they know the incentives and regulations in the area better, and they simply care more about you than large businesses trying to get into your pocket and overprice you. While multi-state solar companies might try to convince you by financial stability and “quality of installations across different locations”, try to choose a local company that meets all your criteria.
What Does a Solar Installation Look Like?
Here’s how a solar system installation will look like once the design for your solar system is approved:
– First, a solar installer should estimate your energy needs, and analyze your annual and monthly electricity consumption, which you can find on utility bills measured in kilowatt-hours (kWh). Such calculations will help to understand potential savings, payback period, and the system size you need.
– A home energy audit is something every experienced solar company would do to understand the size and output needed.
– Next question on the list: are your house’s roof conditions good enough for installation? A solar installer should carefully inspect the roof and ensure its conditions and orientation are good to go, how and where to better place solar panels and wire the system.
– Next, they will design the system and show you how it’s going to look.
You will usually need a permit to install solar panels from your local authorities, and the solar provider should handle all the paperwork.
– The entire process might take up to 3 months depending on the state and local regulations, while the system installation is usually up to 3 days (might take longer depending on roof conditions and system complexity).
– The installation crew should always clean up and remove any debris, leaving your house in good condition.
– When the system is installed, it should be checked and approved by local municipality inspection.
– If you’re connecting your system to the grid, it has to be wired to your local utility system. You’ll apply for connection through your utility company, which will also want to inspect your system to ensure it’s following utility guidelines. Some installers may help you with this step, so always ask. Once you have all the permits, your system will be up and running, powering your home with solar.
