Going solar in the Evergreen State might be easier than you think. Our team has talked to thousands of solar customers across the country, including dozens in Washington. Here’s what to expect and what to look out for.
In Washington, a typical residential solar panel system costs $9,380 to $26,800, depending on the size of your system and what financial incentives you qualify for.
Jump to insightThe federal investment tax credit (ITC) is the most significant financial incentive for most homeowners buying solar panels in Washington.
Jump to insightThe best solar energy companies have a few things in common: great reviews, transparent contracts, reliable equipment and comprehensive warranties.
Jump to insightCompare at least three solar quotes, and be cautious of companies that provide significantly lower estimates than others (this may indicate lower quality). Here are more tips for finding the right contractor for you.
Average solar panel costs in Washington typically range between $9,380 and $26,800. This doesn’t include the cost of a solar storage battery — which sometimes costs as much as the panels.
The size of your solar panel system is a big factor in your total cost. It also depends on what incentives you’re eligible for, the condition of your roof and how much sunlight exposure it gets. Most installers set the price according to the system's wattage, with a typical cost between $2.50 and $5 per watt. In Washington, the average cost per watt is $2.68.
Average solar installation cost by system size in Washington
5 kW | 6 kW | 7 kW | 8 kW | 9 kW | 10 kW | |
---|---|---|---|---|---|---|
Before federal tax credit | $13,400 | $16,080 | $18,760 | $21,440 | $24,120 | $26,800 |
After federal tax credit | $9,380 | $11,256 | $13,132 | $15,008 | $16,884 | $18,760 |
Getting solar panels is like buying a car. You could pay cash, but many finance instead. A solar loan works like most other types of loans — there is an application process, and you pay it back over time with interest. Using a home equity line of credit or loan to finance a solar installation can be another option.
Solar panels are designed to last 25 to 30 years.
Leasing solar equipment is an attractive option for people who don’t want to get a loan or be responsible for maintaining a system. Washington also has legalized power purchase agreements, which work very similarly to leases.

The federal solar investment tax credit (ITC) is usually the most significant financial incentive for homeowners. There’s also a sales tax exemption on solar equipment, labor and services.

Financial savings and energy independence make going solar worth it for a lot of Washington homeowners. On average, Washingtonians with solar panels can avoid $59,116 in total utility costs over 25 years.
One resident, Anthony in Seattle, said his monthly bill went from $400 to $40 after going solar. “But I'm pissed off with what PSE&G is charging me,” he said, noting that the $40 he’s each month is essentially the utility company’s service fee.
Homeowners with solar panels typically save $20,000 to $90,000 over 25 years.
For others, the savings are nice, but it’s not the primary motivation. Richard in Lakebay told us the decision to go solar was “based on reducing the impact our all-electric home imposes on the environment.” He also hoped to set an example for others.
High upfront costs and long payback periods still make some hesitate about solar. We suggest using NREL’s PVWatts Calculator to estimate how much electricity a solar panel can produce over a year on your house — just type in your address. Project Sunroof is another free solar savings estimator.
» STILL NOT SURE? Solar energy pros and cons
We are not aware of any legitimate programs for free solar panels in Washington. However, you can lease a solar energy system with little to no upfront costs. Just look out for scams that promise free solar panels — they can end up costing you quite a bit of money.
» FREE SOLAR PANELS: Are they really free?
Most electrical work requires permits and inspections by the Department of Labor and Industries (or local jurisdictions in some cities). Permit fees typically range from $50 to a few hundred dollars, while interconnection application fees vary by utility company.
Plenty of unshaded roof space that faces south or west is best for optimal sun exposure. Washington averages 2.5 to 5 peak sun hours each day. However, if you have a lot of shading around your house, they might not get enough sun to power your home. It’s also smart to upgrade any old, inefficient appliances first. Solar photovoltaic (PV) technologies, more commonly known as solar panels, absorb sunlight and convert it into usable electricity.
As a rule of thumb, if your roof is more than 10 years old, consider fixing it before going solar. Installing solar panels on an old roof might mean you have to remove the panels, replace your roof and then reinstall the panels. This will cost around $5,000 for a 19-panel setup.
» SHOULD YOU: Replace your roof before going solar?
A solar broker is a middleman or intermediary who helps connect homeowners with solar installation companies. A solar installer specializes in designing, procuring and installing solar panels and related components.
Ultimately, deciding between a broker or solar installer depends on how much you want to be involved in the process. A broker can be helpful if you value convenience. If you want more control and potentially lower costs, working directly with a solar installer is best.
Net metering lets homeowners get credits for extra electricity their solar panels generate. In Washington, each credit is typically valued at the full retail rate, which means you get the same value for the excess electricity as you would pay for electricity from the utility company.
If you put back more than you used, you get a credit toward next month's bill for the extra amount. If you use more than your system produces, you only pay the utility company for that additional amount. The program is open to new participants through at least Dec. 31, 2025.
» GREENEST STATES: Washington ranked second in 2024
The ConsumerAffairs Research Team used a research-backed, data-driven approach, which was informed by our expert editors, to choose the best solar companies. For this guide, we objectively weighted several key features to get our final rankings:
Reviews, ratings and testimonials: 40%
We analyzed solar company reviews by verified solar customers to gauge real-world satisfaction. Companies with generally positive feedback on our site scored highest in this aspect. Those with the most 4- and 5-star reviews by verified Washington customers were given preference.
Warranties: 20%
A long warranty is important — it shows that a company stands behind its products and services. We compared companies on both equipment and craftsmanship warranty terms. All of our top picks for professional installation have warranties or production guarantees of at least 10 to 25 years.
Equipment selection: 20%
We evaluated each company’s selection of solar panels, storage batteries and inverters. Those with proprietary technology or a wide equipment selection from trusted brands ranked highest.
Financing and payment options: 10%
We gave preference to companies that offer multiple payment and financing options for transparent terms and conditions.
Reputation and local experience: 10%
We prefer to recommend those with a longer time in business and a solid track record of reliability in Washington. Solar is a booming industry, and there are some sketchy installers out there. Company history, current reputation, mission and values were also considered.
Our goal is to highlight solar companies that are best equipped to meet most Washingtonians’s needs. The team regularly evaluates customer reviews, company information and industry trends to update our top picks:
