Even such a small sized state as Delaware continues to raise its solar capacity quickly enough. Despite the fact that Delaware isn’t the sunniest state, the solar industry is developing pretty fast there thanks to the strong solar policies. Moreover, Delaware has one of the best net metering policies in the US, which fully supports the distributed solar market. All the above proves it is a great decision to go solar there.

The Cost of Solar Panels in Delaware

The average cost of solar panels in the state is $2.65/W. The total installation price depends on the location, type, size of your home, the type of solar panels and inverter you buy, and many other factors. However, the sum you will probably pay for a typical 6 kW system will be about $11,700, declaring the 26% federal solar tax credit.

Delaware Solar Rebates and Tax Credits

Federal Tax Credit (ITC) – With the Federal Investment Tax Credit you will be able to save 26% of your solar system’s cost. Note that the ITC is available only to those, who buy their system explicitly with a cash purchase or solar loan.

Some local electric utilities offer their own rebate programs:

  • Delmarva Power and Light – The utility will pay $0.55/W of solar generating capacity up to 5 kW, and $0.20/W beyond 5 kW. However, the rebate value tends to decrease with the number of homeowners willing to install a PV system.
  • Delaware Electric Cooperative – For the solar installation up to 5 kW taxpayers receive $0.85/W, and $0.25/W for any additional solar capacity.
  • Delaware Municipal Electrical Corporation (DEMEC) – The Municipal Green Energy Program will pay you a cash rebate for a portion of solar installation costs, depending on the location you live.

Delaware Solar Incentives

Net Metering Program – The undeniable advantage is that the Net Metering Program in Delaware allows you to sell electricity to the utility at the retail rate. Considering that your PV system will definitely produce more electricity than you need, it is significant for you to sell the surplus at a good price. It’s available to anybody who produces electricity using renewables, including solar energy, of course. Companies providing Net Metering in Delaware:

  • Delmavra Power and Light (DP&L) offers net metering to residential customers with eligible systems of up to 25 kW, as well as to farm customers (up to 100 kW)and non-residential customers (up to 2 MW).
  • Delaware Electric Cooperative (DEC) offers net metering to residential customers with eligible systems of up to 500 kW.

Solar Renewable Energy Certificates (SRECs) – Residents may sell the SRECs generated by their solar panels thanks to this program. Whereas the approximate rate for these credits is $25/MWh, a typical 5 kW system could make an extra $2,500 over its lifespan from selling credits in the SREC market.

Pros and Cons of Buying Solar Panels in Delaware

Cons of buying solar panels

  • Lack of solar irradiation

    It’s obvious that the state gets less sunlight than those situated in the more southern parts of the country. However, there are about 200 sunny days per year, which is almost 7 months out of 12.
  • Costly installation

    Unfortunately, the residents can’t benefit from state’s tax credits or rebates, so purchasing and installing a PV system may be pretty expensive. However you still may enroll in your electricity supplier's Net Metering or rebate program.
  • Large area is needed

    On average, 20-25 panels are required to cover all energy needs of a household, which implies a large rooftop space or large area of land needed to install them. Anyway, you are the one to choose where to install your panels.

Pros of buying solar panels

  • Renewable portfolio standard

    Delaware is a great place to go solar due to a solid renewable portfolio standard. State law mandates that Delaware’s utilities derive at least 25% of their energy portfolios from renewable sources by 2025, which contributes to the growth of the SREC market in the state.
  • Local electric utilities’ support

    In order to support Delaware residents and draw their attention to renewable energy, local utilities give the opportunity to use their own rebates on the purchase and installation of solar panels, which is a great benefit.
  • Long-lasting effect

    Solar panels can power your house for at least least 25 years. Generally, a PV system can serve much longer, but at a slightly reduced efficiency.
  • Relatively short payback period

    A solar system installed in Delaware will pay off in 6.5 to 8 years.Then you will be able to use free electricity during the 30+ lifespan of your PV system.
  • Great savings on a monthly electric bill

    When you install a solar energy system on your home, you start to generate your own electricity. It means that you become less dependent on your local utility company and their utility rates, which are highly influenced by inflation. Even though you are paying for your PV system, you will be saving a great deal on the monthly electric bill.
  • Net Metering system

    The state has Net Metering policy in place, allowing households and businesses with small-scale rooftop and customer-sited solar panels to receive credits from utilities for putting excess electricity on the grid.
  • Environmental responsibility

    Besides saving you money every month, solar energy is a truly clean, renewable, and sustainable power source. Sunlight is abundant and is ready to be harvested without any harm to the environment. What's more, installing an average-size solar system will mean saving 208 trees every year. It is proven that using solar energy instead of fossil fuels will decrease our carbon footprint by reducing air and water pollution.
  • Almost no maintenance required

    Solar panels do not have any moving parts, so essentially there is no wear and tear with their usage. Thanks to this, solar panels are completely silent when working. The only maintenance that they need is the occasional cleaning from the dust, ice or snow.

Is it worth going solar in Delaware?

Over the last 10 years the price on solar panels have fallen by more than 80%. What makes PV systems a definitely brilliant investment in 2020 is that they can be subsidized by the 26% federal tax credit and the Net Metering law in Delaware. In addition, it is a long-term investment, because in 25 years each kW you consume will cost you 5 times less than today.

I am claiming the 26% Federal Tax Credit (ends 2022) i

When you install a solar system, 26% of your project expenses apply toward a credit to offset any taxes you owe that year. This federal tax credit is a major incentive to go solar, but it is going to be phased out by 2024.

To be eligible to claim this credit, you must owe federal taxes.
