Solar Incentives and Rebates in Washington

Washington, D.C., has some of the best incentives available for solar energy.

The federal solar incentives are important to remember, particularly regarding the tax credits.

With the help of the Investment Tax Credit (ITC), also known as the Residential Clean Energy Credit for home systems, the cost of your PV solar energy system could go down by 30%.

Unless you are a tax-exempt corporation, in which case you might be eligible for a direct payment, keep in mind that the ITC is only available to people who buy their PV system outright (with cash or a solar loan). In addition, you must make enough money to qualify for the credit.

There are a few other D.C. solar initiatives that you can take advantage of in addition to obtaining utility bill credits for any excess solar electricity your panels produce, including:

Certificates for solar renewable energy (SRECs)

The District of Columbia wants to reduce electric bills by 50% by 2032 by providing solar energy to low- and moderate-income homes. And you can get paid to help them reach this goal.

Under this program, you get one D.C. SREC for each MWh of clean electricity your panels generate. You can then sell these certificates on the SREC market.

SRECs were more expensive in DC in 2021 than anywhere else in the nation, selling for between $365 and $435 per unit. At the bottom end of that range, an 8 kW system that produces 8 MWh annually would create an additional $2,920 annually.

Affordable Residential Solar

The Solar Advantage Plus Program offers an exceptional incentive for eligible people of modest income in Washington, D.C.

With the help of this first-come, first-served rebate scheme, qualifying applicants can get up to $10,000 to pay for a 3kW to 4kW solar system in full.

Participants will not only be the owners of the system and the energy it generates, but they will also be able to sell the SRECs mentioned above.

Net Metering in Washington

When mounting solar panels on your roof, it’s crucial to make sure you get credit for the entire amount of power your system generates.

Fortunately, Washington, D.C., has a net metering policy that credits you for any excess electricity your system produces and lets you utilize those credits to make up for any insufficient power produced by your system.

Pepco (Potomac Electric Power Company) offers the Washington, D.C., area’s top utility net metering program.

Tax incentives for solar energy in D.C. Property tax exemptions

You can also save money on your property taxes by installing that solar energy system and taking advantage of the Personal Property Tax Credit for Solar Energy and Cogeneration Systems.

How Much Does Solar Cost in Washington?

Over the past few years, solar energy has gained appeal as a renewable source of electricity. Homeowners who wish to cut their carbon footprint or save money on their power bill may find solar panels and installation an appealing alternative because of their decreased cost.

Determining the average price of solar energy in Washington, D.C., still needs further research. However, we can estimate that residential solar installation typically costs between $10,000 and $20,000.

The price may vary again depending on size when it comes to large-scale installations. Businesses generally favor larger solar installations compared to homeowners.

Furthermore, a solar panel’s size and installation point affect how much electricity it produces. For example, a small rooftop system will produce approximately 10 kilowatts (kW) of electricity per year, while a large ground-mounted array could yield up to 1 megawatt (MW).

The initial investment is sometimes the biggest expense when examining the entire cost of ownership. Once installed, however, the savings in monthly bills can offset the costs within five to seven years.

How Big a Solar System Do I Need in Washington?

If you’re interested in going solar, you should first determine your needs.

If you are in a sunny area, you might only require a little space. But you’ll probably need a larger system if you reside in a cloudy area.

A good general rule of thumb is to multiply the square footage of your roof by 0.5.

So if your roof covers 500 square feet, you need around 1,000 watts of power.

Is It Worth It to Go Solar in Washington?

Solar is worth it in Washington, D.C.

In fact, solar panels are worth it in most places, though how quickly you break even on your investment will depend on things like the cost of electricity, available incentives, climate, and sun angle.

You can save up to $43,784 over 20 years by putting in an average solar system. If you choose to pay for your system with a loan that requires no down payment, you can start saving money in Washington, D.C., immediately.

How Does Net-metering Work in Washington?

Customers of utilities with net metered systems will receive credit for each kilowatt their system produces. They will receive monthly bills for the sum of the kilowatt hours they used and the kilowatt hours they produced.

You will receive credit for each additional kilowatt per hour you produce in a given month compared to what you consume.

This credit can be used when you make less electricity than you use in a later month.

The credit for overproduction will carry over from month to month forever.

Other Kinds of Net Metering in Washington

There is a virtual net metering system available in Washington, D.C.

D.C. Bill 20-0057 gave people in D.C. the option to buy electricity from community renewable energy facilities through virtual net metering (CREFs).

Facilities must have a capacity of less than 5 MW and at least two users.

Subscribers to CREF own or rent a “share” of the facility. Based on the size of their share, their utility bill is credited each month for a certain number of kilowatt hours.

What Are My Options for Installing Solar Panels in Washington?

There are two major possibilities when weighing the options for a solar panel installation for your house or place of business. These options are a grid-tied system or an off-grid system.

Grid-tied systems are directly connected to the utility company’s electrical grid. Meanwhile, off-grid systems use batteries to store extra energy throughout the day to generate power at night.

Off-Grid vs. Grid-Tie Systems

Both varieties of systems have advantages and disadvantages.

Grid-tied solar panels offer a steady supply of clean energy 24/7. However, you must pay a premium for the service. As a result, your final cost will probably be more than if you had chosen an off-grid solution.

Off-grid systems are less expensive because they don’t rely on the utility company. They also allow you to generate all of your own power. However, this type of system requires a battery bank to store energy. These batteries may significantly increase the system’s weight.


Setting up solar panels is a fantastic method to cut costs and lessen your carbon footprint.

Not only will you have clean energy coming into your home, but you’ll also be helping the environment. And if you live in the D.C. area, you might even qualify for tax credits from the government.
