That’s why we’ve done the research for you and reviewed nine of the best-known solar companies in Washington below. Of course, everyone’s needs and circumstances are different.

Solar Energy In Washington

Unfortunately, Washington does not rank very high when it comes to solar. It sits at a dismal 36th place in 2021 when it comes to total installed solar capacity. There are various reasons for this: conventional non-renewable electricity costs in Washington state are the second lowest in the country. This means that Washington residents have less incentive to generate their own power. Additionally, it is only during Washington’s sunny summer days that solar panels are able to generate the most electricity. However, residents in the state actually use the most power in winter when heaters come online.

That being said, declines in solar installation costs over the past decade coupled with advancements in battery storage technology mean that solar is looking like an increasingly smart investment for Washington residents right now. Washington state is looking to add 824 MW of solar capacity over the next five years. If all goes well, that would more than triple the state’s current solar capacity of 258 MW.

Laws & Regulations

The Washington State Senate passed the 100% Clean Electricity Act in 2019 which requires public utilities in the state to go carbon neutral by 2030. In addition, 100% of their energy needs would need to be met by renewable sources by 2045. This is one of the most ambitious clean energy bills in America. Only three other US states so far have committed to 100% renewable energy.

When it comes to residential-scale solar panels, Washington’s laws are similar to many other states. You are legally allowed to place any type of solar panel on your property, and homeowner’s associations are not allowed to prohibit solar panel installation.


Washington state does not issue specific solar licenses. Instead, the state requires all electrical work (including solar panel installation) to be performed by a licensed Electrical Contractor. The North American Board of Certified Energy Practitioners, or NABCEP, does have a respected certification program for Solar Professionals though. Many of the solar companies on our list above employ technicians with this extra qualification. The NABCEP also has an accreditation program for solar companies, but no Washington-based company has been accredited so far.

Net Metering

Net-metering refers to a system where you sell renewable electricity back to your utility, offsetting your electricity bills. This system allows you to save big on electricity costs with your solar array. Three major utility companies in Washington offer this program to their customers: Avista Corporation, Pacific Power & Light Corporation and Puget Sound Energy. Your solar array has to be below 100Kw in capacity in order to qualify. This system was last amended in 2000, when regulations were changed to make qualifying for the program easier.

Tax Credits and Incentives

The federal solar tax credit (ITC) applies in Washington state. Through this scheme, you can receive a tax credit equal to 26% of your solar installation’s cost. This tax credit falls to 22% for a solar installation in 2023, before phasing out altogether from 2024 onwards.

The 2019 100% Clean Electricity Act passed by Washington state also exempts all solar energy systems from sales tax. Qualifying for this tax exemption is easy – it applies to all solar arrays between 1 and 100 Kw in capacity and installed by a licensed electrical contractor.


Washington state might be slow on the uptake when it comes to solar, but that doesn’t mean you also should. With falling solar installation costs and very generous tax incentives, there has never been a better time to invest in a solar energy system. Our list of recommended solar companies is a great starting point if you’ve been convinced, but keep in mind that every property is different. We encourage you to shop around and do some further research of your own into the best solar company for your needs. Happy hunting!


What are the different types of solar energy system, and which should I go for?

There are two main types of residential solar energy system: a grid-tied system and an off-grid system. A grid-tied system is connected to your local power grid, allowing you to sell any excess electricity which your solar panels generate back to your utility. An off-grid system is not connected to other utilities, and the excess electricity needs to be stored in batteries.

A grid-tied system is the best choice for most residential solar energy installations. For one, it’s cheaper to install since you don’t need to pay for extra batteries. You can also offset your utility bill by selling power through your local grid.

Is there enough sun in Washington state for solar energy to be worth it?

Yes, there is definitely enough sun to go around even in overcast Washington. The state’s long summer days are ideal for generating solar power, making up for the weak winter sunlight. Another bonus is that solar panels generally work better in lower outdoor temperatures like Washington’s. The state has also been actively investing in large-scale solar projects, like the 193 MW Lund Hill solar plant, a sign of how feasible solar power generation is in Washington.

What solar rebates are available for Washington state?

Washington residents qualify for both the federal solar investment tax credit (ITC) and the state solar sales tax exemption. The ITC gives you a tax credit equal to 26% the cost of your solar installation, which directly lowers the amount of income tax you need to pay, while the state tax exemption means that you don’t need to pay sales tax on your solar installation.

Can my roof support a solar installation?

While most roofs are capable of supporting the weight of a solar array, it’s better to be safe than sorry. Many solar companies offer free consultations which you can take advantage of to confirm the feasibility of installing solar panels. Older roofs or rooftops made out of certain woods occasionally need to be replaced before solar panels can be installed. In other cases, while your roof might be sturdy enough for a solar installation, it’s orientation might make solar panels inefficient for your property.
