How Much Can Solar Panels Save You in Sammamish, Washington?
Finding out how much you can save on solar in Washington, is not a straightforward answer. It depends on several factors, including the solar billing of your utility company, the size of a potential solar system on your roof, and your household’s energy consumption. While most solar installers will try to cover all your electricity needs, the actual savings will depend on your home’s unique conditions. To get a personal estimate of how much you could potentially save by going solar, fill out a simple form on our website, use Google’s Project Sunroof solar savings calculator, or consult with a couple of local solar installation companies for a personalized savings calculation.

Solar Financing Explained
You can pay for solar panels in a couple of ways:
- Cash
- Installer solar loans
- Personal loans
- Cash-out refinance or HELOC
- Solar Leases or Power Purchase Agreements (PPA)
First, there is a cash purchase, which in most cases provides the best price and long-term savings, but the upfront payment is not always what you can afford. If you want to own your solar panels and don’t have about $15,000 to $20,000 in the bank, you’ll have to choose solar panel financing.
You can consider a personal loan, a home equity line of credit, or a solar loan offered by the solar company. However, keep in mind that these loans come with interest and additional fees. Solar loans often are tied to dealer fees, which can increase the total cost of your solar system by 20% or more in exchange for a lower interest rate. To ensure you get the best possible deal, it is wise to compare the dealer fees and interest rates offered by different installers. This way, you can make an informed decision based on the most favorable terms available.
Some companies offer solar leases or PPAs that require zero upfront cost. But in such cases, you don’t own solar panels and you are not eligible for any solar rebates or the federal tax credit. And, because you have to pay the solar company monthly, your total solar savings will be lower. Ask for detailed savings calculations from a solar installer to decide on the best option. In most cases, you will still be paying less for electricity.

Washington Solar Incentives and Rebates
Thinking about solar in Washington? The incentive situation here isn't quite as robust as what you'll find in Oregon or California, but there are still a few things working in your favor. The state doesn't hand out big rebates or tax credits, but a couple of programs can help bring your costs down.
1. Net Energy Metering
Washington's got net metering laws on the books—officially, it's RCW 80.60.030 if you want to dig into the legal details. What it boils down to: when your panels crank out more electricity than you're using at that moment, the extra power goes back into the grid and you get credit for it.
You can tap into the grid whenever you need to—nighttime, during those stretches of gray drizzle we're famous for—and those credits you've banked will offset what you pull. Most of the utilities across the state participate in this. It's not the most generous net metering setup in the country, but it does help trim your electric bills month to month.
Your meter basically spins backwards (or the digital equivalent) when you're pushing power to the grid. Those credits stack up on your account and get used when you're drawing from the utility. You won't get a check in the mail, but your bills will definitely be smaller.
2. Sales Tax Exemption
This is where you actually save some real money upfront. Washington exempts solar equipment from state and local sales tax through ESS Senate Bill 5116. The exemption runs through the end of 2029.
For home systems under 100 kilowatts—which covers basically every residential installation—you pay zero sales tax on the equipment. Depending on where you live in Washington, the combined state and local sales tax can hit 8%, 9%, or even 10% in some areas. On a typical system, that's saving you well over a thousand bucks.
There's also a 50% sales tax exemption for bigger systems between 101 and 500 kilowatts, but that's more for commercial setups. Most homeowners won't need to worry about that part.
3. Federal Income Tax Credit
The federal credit is honestly what makes solar pencil out for most Washington folks. You get 30% back on everything—panels, inverters, the installer's labor, permits, the whole package.
A typical 6 kW residential setup in Washington is going for about $18,500 right now (October 2025 numbers). Apply that 30% federal credit, and you're down to around $12,950 out of pocket. That's about $5,550 in savings from this one credit alone.
Here's a nice bonus: the credit now covers battery storage systems too, as long as they're at least 3 kilowatt hours. Given how winter storms can knock out power around here, a lot of people are throwing batteries into the mix for backup. Good to know those qualify for the credit as well.
Same deal as everywhere: you've got to own your system, either buying it outright or financing it. And you need enough federal tax liability to actually use the credit. If you don't max it out in one year, it carries forward. Important: Legislation signed into law on July 4, 2025, eliminated this program after December 31, 2025. You must have your system installed by that deadline to claim this credit.
What Washington Doesn't Offer
Let me level with you—Washington doesn't have any state solar tax credits or rebate programs. We used to have this production incentive that actually paid you for the electricity your panels generated. That ended in 2020, and nothing's replaced it.
Some utility companies might have their own small programs or incentives, but they're all over the map and usually not very substantial. Worth asking your utility if they offer anything, but keep your expectations low.
What You're Really Looking At
Between that 30% federal credit and dodging sales tax (which saves another 8-10%), you're cutting roughly 38-40% off your total costs.
So that $18,500 system ends up costing you somewhere around $11,100 to $11,500 after both breaks. Here's the thing, though: Washington's electricity rates are actually pretty reasonable. They've held fairly steady compared to a lot of other places.
What that means for you is payback periods tend to run longer here—most people are looking at 14-18 years before they break even. Solar can still make sense if you use a ton of electricity, you have decent sun exposure (and yeah, even cloudy Washington gets enough sun to make it work), and you're not planning to move anytime soon.
One thing people don't always realize: Washington gets more sun than you'd think, especially if you're east of the Cascades. Even around Seattle and the coast, you can pull solid power from solar. The panels actually perform better in cooler temps, which helps make up for those short winter days.
Just keep in mind that federal credit only helps if you're paying federal income taxes. If your tax bill runs on the lower side, you might not capture the full benefit right away. It does roll forward to future years, but it's worth thinking about. Probably smart to talk through your specific tax situation with your installer or maybe an accountant before you commit to anything.

How We Rank Solar Installers
Our main goal is to provide homeowners like you with top-rated solar companies you can trust. Our solar experts analyzed thousands of local and nationwide installers to get to the bottom of who is best in a specific location. The solar company ranking methodology is based on gathering input from homeowner surveys, consulting with industry experts, and extensive research into the solar energy market.

In short, here’s how we pick top installers:

- Local solar companies over big national ones are covering multiple areas, and they can provide better personal attention and learn more about the solar needs and regulations in their area.
- Companies with hands-on experience and a wealth of projects under their belt are more likely to deliver efficient and timely installations that cater to specific customer needs.
- Companies that handle their own installations instead of outsourcing to subcontractors ensure a higher caliber of work and nurture a culture of excellence and accountability in service.
- Select a company that has a good overall reputation and reviews on sites like SolarReviews, BBB, Google Maps, and Yelp.
- The company is licensed and insured and holds relevant certifications such as NABCEP certification.

How We Classify Solar Installers: What Matters Most?
What to Look for In a Solar Company
To ensure that you partner with a great provider that can meet your needs of going solar, look for the following:
- Make sure the solar installer has industry-standard certifications, such as those from the North American Board of Certified Energy Practitioners (NABCEP), indicating that they meet the gold standard in renewable energy installations. Also, verify if they are licensed, bonded, and insured for residential solar projects in your area. If subcontractors are involved, check their credentials as well.
- Prioritize installers with a proven track record in solar installations, ideally with at least 5+ years of experience. Ask about the number of systems they’ve installed and their project portfolio. A competent installer should openly discuss the solar panels, inverters, and batteries they use if they help to take advantage of local solar incentives and rebates, and warranty coverage specifics.
- Your installer should be forthcoming about the installation process and answer any questions you might have, like “How many solar panels will I need? Why?”, “Can you give me a detailed cost breakdown based on my energy consumption?”, “What solar panel brands do you install? Why?”, etc.. They should also be transparent about their use of subcontractors, detailing their roles and how their work will be supervised.
- A preliminary evaluation of your roof’s condition is the groundwork. The installer should advise on necessary repairs to ensure it’s ready for solar panel installation and clarify responsibilities for any potential roof damage during the process. Discuss aesthetic concerns, such as the placement of solar panels around roof vents or the possibility of relocating vents for a more visually appealing setup.
- Check the installer’s reputation through online reviews and testimonials. They should be able to connect you with past customers willing to share their experiences. Personal recommendations from friends or neighbors who’ve gone solar can also be invaluable.
- Solar installation costs can vary widely, so obtaining multiple quotes is advisable. Experienced installers will adjust their offers to your home’s specifics—size, energy needs, etc. For an objective cost comparison, calculate the price per watt of the proposed system, giving you a standardized basis to evaluate different quotes.
Should You Choose a Local Solar Installer or a Big National Company?
Always choose a local solar company over a big national corporation. Small local companies that operate in a distinct local area are better than multi-state and national solar companies and large corporations. It’s the small local companies who get the best reviews on our website, and it’s the national multistate companies who get very poor reviews. Why so, you may ask?
Solar is a local service business, for the most part, and it is extremely difficult to run a solar company and offer good customer service to many locations from a central office.
Local ones have a community connection, they know better the incentives and regulations in the area, and they simply care more about you than large businesses trying to get into your pocket and overprice you. While multi-state solar companies might try to convince you by financial stability and “quality of installations across different locations”, try to choose a local company that meets all your criteria.
What Does a Solar Installation in Sammamish, Washington Look Like?
Here’s how a solar system installation will look like once the design for your solar system is approved:
- First, a solar installer should estimate your energy needs and analyze your annual and monthly electricity consumption, which you can find on utility bills measured in kilowatt-hours (kWh). Such calculations will help you understand potential savings, the payback period, and the system size you need.
- A home energy audit is something every experienced solar company would do to understand the size and output needed.
- Next question on the list: are your house’s roof conditions good enough for installation? A solar installer should carefully inspect the roof and ensure its conditions and orientation are good to go, how and where to better place solar panels and wire the system.
- Next, they will design the system and show you how it’s going to look.
- You will usually need a permit to install solar panels from your local authorities, and the solar provider should handle all the paperwork.
- The entire process might take up to 3 months depending on the state and local regulations, while the system installation is usually up to 3 days (might take longer depending on roof conditions and system complexity).
- The installation crew should always clean up and remove any debris, leaving your house in good condition.
- When the system is installed, it should be checked and approved by local municipality inspection.
- If you’re connecting your system to the grid, it has to be wired to your local utility system. You’ll apply for connection through your utility company, which will also want to inspect your system to ensure it’s following utility guidelines. Some installers may help you with this step, so always ask. Once you have all the permits, your system will be up and running, powering your home with solar.
