Delaware has been ranked among the top three states for harnessing solar power. Consumer Affairs compiled a list of the best states to go solar based on electricity prices, solar policies, installation costs, and available incentives. Delaware ranked highly due to its rebates, tax credits, and money-saving opportunities.

What is the Cost of Going Solar in Delaware?

As of March 2025, the cost of going solar in Delaware is $2.40 per watt. At that rate, a 5KW installation would cost $12,002. Prices range from $10,822 and $13,802.

What Solar Incentives Are Available in Delaware?

The following incentives will help you save on solar installation:

• The Residential Clean Energy Credit: Offered by the federal government, the Residential Clean Energy Credit reduces your tax bill by 30% of the cost of going solar. If your credit exceeds your tax bill, it will roll over into the following year. The credit is set to reduce to 26% in 2033 and 22% in 2034 before phasing out, meaning it’s best to go solar sooner rather than later.

• Green Energy Program Rebates: This program allows residents who go solar to earn rebates from most utility companies. Delmarva customers can apply for a refund of 70 cents for every installed watt of solar energy for a maximum rebate of $6000 but must sign over their SERCs as part of the deal. Newark Municipal Electric Company clients can receive $1 for every watt of installed power up to 5kW and 50 cents per kW thereafter and may keep their SRECs. Delaware Electric Coop customers can receive rebates of 35 cents for the first 5kW and 20 cents for each subsequent watt. The program is limited by annual funding and available in most municipalities. It could also take up to two years for some households to receive rebates.

• Solar Renewable Energy Certificates (SRECs): Delaware residents are awarded SRECs for every megawatt-hour (MWh) of electricity their solar panels generate. You can sell your SRECs for cash at the end of the year. Prices fluctuate over time based on your contract terms but generally range from $10 to $30.

• Low to Moderate Income Solar Pilot Program: The pilot program provides 4kW systems to low-income Delaware residents and a 70% discount to moderate-income residents on systems up to 6kW. You can apply through the Delaware Department of Natural Resources and Environmental Control.

• Net Metering: This program allows Delaware residents to sell back unused clean energy to their utility company for a credit on their utility bill. Net metering is available for residents on systems up to 25kW regardless of your provider.

What to Consider When Choosing a Delaware Solar Installer

Here are some things residents should consider when choosing a solar provider that’s right for them.

• Cost: Residents should look beyond the initial cost of solar and consider the value they get for their money. Some companies also offer financing, which can make solar more affordable.

• Warranties and Guarantees: Consider warranties and guarantees on products and workmanship to avoid extensive repair and replacement costs.

• Equipment: The installer should provide efficient equipment that helps you get the most from your installation.

• Services: Many installers provide services beyond solar installation, including roofing, EV charger installation, and battery storage. Work with a provider that offers the comprehensive services you require.

• Reputation: Read online reviews and explore installers' websites to learn about their history and the quality of service they provide.
