There can be solar tax credits and incentives available at the federal, state and local levels. The calculator above will show you the value of all incentives your home is eligible for.
Governor Jay Inslee needs some introductory theme music for this page. It should be snappy, hot, and full of swagger. In 2019, he helped lead a coalition of smart solar policy warriors to finally get the new solar law enacted they’ve wanted for ages.
That law, The Solar Fairness Act, expanded net metering and re-introduced a sales tax exemption for solar. All that support from the legislature adds up to a big jump in your solar incentive savings.

The federal solar investment tax credit will have the biggest impact on the cost you will face to go solar in Washington
If you install your photovoltaic system before the end of 2032, the federal tax credit is 30% of the cost of your solar panel system. This is 30% off the entire cost of the system including equipment, labor, and permitting.
Example: If your solar energy system costs $20,000, your federal solar tax credit would be $20,000 x 30% = $6,000.
The federal tax credit falls to 26% starting in 2033.
With net metering in some states, you get full retail rate credit for the amount of electricity you send back into the grid with your solar panels.
In 2019, Washington expanded its net metering requirements eightfold. This change should give the solar industry some much needed stability.
The best net metering laws make sure that you get the full retail value of every kilowatt-hour (kWh) of surplus you produce with your solar panels – either in credit to future bills or, if you consistently run a surplus, cash payments at the end of a regular accounting period.
In Washington however, any net surplus you have accumulated and not used as a bill credit are forfeited to the utility on March 31st of each year, without compensation. Don’t fret! This just requires a little more planning to make sure you don’t install more solar power capacity than you will use each year.
While Washington does not have a dedicated state rebate for solar panel installation, some manufacturers like LG offer their own solar rebates. These programs are usually time sensitive. For example, LG offers a $600 solar rebate on their equipment, which your installer can help you redeem over the next year.
In 2019, Washington restarted its 100% sales tax exemption on all equipment, all labor, and all services related to the installation of that equipment from all sales and use taxes on home solar systems up to 10kW. As the sales tax in Washington is currently 9%, that’s nothing to sneeze at when purchasing equipment that costs twenty to thirty thousand dollars. We’d love to see that 10kW maximum bumped up, but otherwise, that’s a model law right there. No twists, no tricks, just savings for smart solar energy.

Thank you to Jeff Bennett, Bill Rudd and his crew for a job well done. Although a slight miscommunication in the beginning and a couple of days delay due to weather your team of professionals worked extra hard to resolve those issues and finish the job. Jeff Bennett helped resolve a miscommunication problem in the beginning to make sure we were completely satisfied.Bill Rudd and his crew were the best, very professional and did great work in difficult weather conditions. Bill especially made sure everything was right with some patchwork inside and outside of our garage. He also discovered a problem with one of the panels in the testing of the system and worked diligently to find and fix the problem. I would highly recommend your company and your people to anyone interested in purchasing a solar system. Thank you, Scott W.

Satisfied in Coupeville, over 1 month
Our garage/office space was new construction and broke ground just a bit before COVID hit. WSW installed solar panels, inverter, battery, and ran circuits to the separate house. They also wired the new building. I can't complement them enough as to how they navigated crazy supply chains, uncertainty with the builders, and working with us to keep us informed about what was going on. I especially appreciate that they used the long installation time to find solutions to our high load amps when the well pump kicked in. Paul and Golda and team kept up to date on the new technologies and were able to source a newly released higher capacity inverter to do the job. The time also allowed us to get a slightly larger battery for the same money because costs kept coming down and technology going up. Can't recommend them enough.

I wanted to write a raving review of A-R Solar as my experience with them and their installation crew was top notch. From the very beginning, being a novice to Solar and the latest technologies, I had only done a few weeks worth of online researching. As with many homeowners, the information out there can be daunting and overwhelming at times. Upon our search for the “right” solar solution, as with many of us, we called around several companies to get the most information, best & affordable pricing, but at the end of the day, a partnership in the solar initiatives. Our phone call landed us with Ian Lucas, our design consultant. From the get-go, Ian was very knowledgeable & a non-pushy consultant. He answered our “dumb” questions round the clock without judgement. My wife and I felt that Ian was looking for our best interest at heart versus the other companies who didn’t even return our phone calls or just wanted a quick sale and move on. Ian gave us truthful information, and “this is what I would do in your situation” without the up sale of additional equipment that we didn’t need. We were sold with Ian. Next steps, the Project Manager : AJ Mullen. Again from the get-go, she came for a site visit, gave us a run down of the project and what to expect. Open and constant communication along the way. The PM makes it all happen with the coordination and resources. Lastly, the installation Crew consisting of Ari, Travis and Colton. These guys were very passionate about their work. As if they live and breathe it and you could easily see it in the expression and craftmanship. I joked with my wife, “these guys were eager beavers” to prep the site, install, and clean up every evening. Very detailed oriented and we all got along fantastically. (is that even a word ). I can go on and on but you get the jist of my review and my future recommendation to all my neighbors and friends. From start to finish, and everything in between, you must be doing something right in hiring and finding such fine professionals in the Solar industry. I wanted to personally thank you A-R for such a pleasure experience into the future of solar and definitely thank Ian, AJ, Colton, Travis and Ari on my behalf. Cheers, Matt T.

Customer service was fantastic. Very responsive to our needs and schedule. Installers have great chemistry and I can't speak highly enough about their work. You'd be making the wrong move to go with anyone else. Best on the OP!

The installation had to coordinated with home addition project that expanded the southern roof exposure. Fire Mountain had everything in place for an efficient install once the roof was ready. Great line of communication with timely updates.

I hired Sunergy 6 years ago. Originally, they did a good job, but here are the problems I've had since the install: 1.) Leaks! There was water intrusion into the inverter!! They "fixed" it by drilling a weep hole. I don't know about you, but I'm *still* concerned about high voltage and water in the inverter! 2.) Leaks in the roof. They do not have proper on-call processes in place when their office is closed. I notified them about the leak and they were only able to get someone to the house to take a look 2 weeks later. 3.) They tried to skirt around their responsibilities to fix the actual damage in #2, and only wanted to put some caulk on the leak. Then they proposed an obviously sub-par (but cost-effective for them) solution to prey on an uninformed homeowner. 4.) They clean your panels with soap that has caused permanent stains on the panels. It has probably caused some loss of production due to this. Given my experience, I can no longer recommend Sunergy Systems.

From sales to installation the process of putting up solar was made easy with Brimma Solar. Installed the complete system in one day. The installation crew was very friendly and respectful and the workmanship was impeccable. Passed inspection first time with no issues. System is working very well.

Ground mount of 36 panel Washington made system with e gauge monitor. Been watching daily through the winter months and we are producing about 1/2 of our power needs, and the best is just beginning! Highly recommend the e gauge monitor (extra 600$) can watch daily production on I pad, see where your use is greatest and what kinds of days are best. Can break out stats from 10 minute intervals up to monthly,yearly. It has really made us aware of what and when we use the most (Water heater ). Totally satisfied with all aspects of South Sound Solar, before,during and after instal. Looking forward to great production this Summer.
