The city currently meets 86% of its energy needs via renewable sources and aims to be powered by 100% clean energy by 2032.


How much solar energy does Washington, D.C. produce?

It is the leading solar city in the South Atlantic region and is expected to add another 246 MW of solar capacity by 2030. * The city had 10,618 solar installations as of 2020—up nearly 150% in the last five years.

What are the advantages of going solar in Washington, D.C.?

Switching to solar can change the world a little at a time, improving air quality and creating jobs. Since 2006, efforts to convert Washington, D.C. to clean energy have reduced carbon emissions in the city by 24% and increased economic growth by 14%.

Not only does solar usage help save the environment, but it also comes with the financial advantage of decreasing your electric bills. A purchased 5 kW system can pay for itself in 4-5 years and offer upwards of $56,000 in energy cost savings over 20 years.*

You may be able to break even on your upfront costs even earlier by taking advantage of tax incentives, rebates, and net metering. Net metering allows you to send any excess energy your system produces back to your utility provider for a credit on your electricity bill that can be used to cover any energy usage from the grid.*

What is the best way to go solar in Washington, D.C.?

The best way to go solar will depend on your personal energy usage, available unshaded roof space, budget, and more. It's also important to consider how much of your electricity usage you'd like to offset and whether you want to aim to produce more than you need to earn more SRECs.
