Solar Installers in Washington, Based in Washougal
Sunbridge Solar is a Washougal-based solar installer serving Clark, Cowlitz, Skamania and Klickitat counties. We have installed home solar in Southwest Washington since 2008. We are a registered, bonded and insured Washington contractor with our own electrical license, and we handle the permit, the utility interconnection and the sales-tax exemption paperwork for you.
- Installing since 2008
- L&I registered, bonded & insured
- 10-yr workmanship · 25-yr product warranties
- 2–3 days on site
Who installs solar in Washington?
Sunbridge Solar does, from an office at 421 C St Ste 5a in Washougal. We are a local company, not a national sales operation that subcontracts the roof work. The people who design your system are the people who put it on your house.
Here is what that means in practice:
- Registered, bonded and insured in Washington. Contractor registration SUNBRSL882NF and electrical contractor license SUNBRSL857CK, both active with the Department of Labor & Industries.
- Installing in Washington since 2008. Clark County’s public permit records list more than 120 Sunbridge solar permits in unincorporated Clark County alone since 2017, on top of our work inside city limits and across Cowlitz, Skamania and Klickitat counties.
- Two warranties, kept separate on purpose. Ten years on our workmanship, 25 years on the panels and equipment from the manufacturer. A “25-year warranty” that only covers the panels leaves the roof work uncovered.
- No-pressure sales. We give you a written quote and let you decide. Nobody from Sunbridge will sit at your kitchen table until you sign.
We are also Energy Trust of Oregon verified, so we serve Oregon customers too. Oregon incentives work differently — Oregon homeowners should start on our Oregon page.

Where in Washington does Sunbridge install solar?
Sunbridge Solar is based in Washougal and installs across Clark, Cowlitz, Skamania and Klickitat counties — from the Vancouver suburbs to the Columbia River Gorge. Pick your town for the details that change the numbers: which utility you are on, who reviews the permit and how net metering works there.
Vancouver metro and north Clark County
Good to know: Clark Public Utilities net-meters systems up to 100 kW; anything from 26 kW up needs additional approval, which we handle in the interconnection application. Inside city limits, start with our Vancouver solar installers page.
Longview, Kelso and the I-5 corridor
Good to know: Cowlitz PUD zeroes out unused net-metering credits every March 31, so we size systems to what you actually use, not to overproduce.
Skamania and Klickitat counties
Good to know: Washington’s 100% sales-tax exemption covers solar equipment and installation labor on systems up to 100 kW through 2029 — it applies here just as it does in Vancouver.
Not on the list?
We take select projects farther out, including Spokane and the Tri-Cities. Call and we will tell you straight whether we can do yours.
What does a solar installer charge in Washington?
The price of a home solar system depends on system size, your roof and whether you add a battery — not on which town you live in. Two things about Washington make the quote simpler than in most states:
No sales tax on the system or the labor
Washington exempts 100% of state and local sales tax on solar systems up to 100 kW, including installation labor, through 2029 (RCW 82.08.962). You sign one exemption certificate at purchase and we file it. There is nothing to claim later.
No state credit or rebate to wait on
Washington has no solar income-tax credit and no state cash rebate, and neither Clark Public Utilities nor Cowlitz PUD offers a solar rebate. The number on your quote is the number you pay. The federal residential credit ended for systems placed in service after December 31, 2025 — see what changed.
For a cost breakdown by system size, read our Washington solar panel guide (or what solar panels cost in Vancouver), or run your own bill through the Washington solar calculator. When you’re ready, request a written quote — it’s free and there’s no obligation.

What does your utility allow?
Every utility in our service area net-meters home solar: the power you send to the grid is banked as kilowatt-hour credits against your own later use. The details differ by utility, and we build them into your design.
Clark Public Utilities
Vancouver, Camas, Washougal, Battle Ground, Ridgefield, La Center and the rest of Clark County
- Systems up to 100 kW qualify for net metering
- Application usually processed within four working days; net meter installed within about five working days after approval
- Application fee $100 for systems under 25 kW ($500 for larger systems, with a longer review) — included in your price
- Unused credits reset every March 31
No PUD solar rebate. We file the interconnection application and the exemption certificate for you.
Cowlitz PUD
Longview, Kelso, Castle Rock, Woodland, Kalama
- Systems up to 200 kW qualify
- $100 non-refundable application fee
- Credits accumulated over the previous 12 months are zeroed out on March 31
No PUD solar rebate. We size systems to what you actually use so you don’t hand credits back.
Skamania PUD
Stevenson, Carson, North Bonneville
- Systems up to 100 kW qualify
- Application fee $200 for 1–25 kW
- The PUD aims to answer a complete application within 20 business days
- Electrical permit and passed inspection required before connection
The same Washington sales-tax exemption applies here as in Vancouver.
Klickitat PUD
White Salmon, Goldendale
- Systems of 100 kW AC or less qualify
- Bi-directional meter installed after the L&I inspection is approved
Ask us about the Gorge wind: we choose racking and roof attachments rated for it.
The annual reset is why we size Washington systems to what you actually use rather than to overproduce: surplus you bank in July is worth full value in January, but anything still unused at the reset goes to the utility. Our post on Washington net metering explains the math.

How long does a solar install take in Washington, start to finish?
The panels go on in two to three days. The whole process, from first call to the day you switch the system on, usually runs eight to twelve weeks in Clark County. Most of that time is permitting and utility paperwork, and we handle all of it.
Consultation, design and a written quote
We look at your roof, your shading and a year of your electric bills, then put system size, equipment, warranty terms and price on one page. Take your time with it.
Permits, install and inspection
We prepare and submit the county or city solar permit and the electrical permit (through Washington L&I, or the City of Vancouver inside its city limits). In our experience, Clark County issues a residential solar permit in about two to six weeks, most often around four. Then it’s two to three days on site, and the electrical inspector signs off on the work.
Utility interconnection and switch-on
We send the signed application and the inspection approval to your utility. Clark Public Utilities usually processes it within four working days and installs the net meter within about five working days after that. Then you switch it on.

How do I choose a solar company in Washington?
Ask any installer these five questions before you sign. They take ten minutes and they sort the field quickly.
Are you licensed, and can I check?
Every Washington contractor has an L&I registration number and an electrical license number. Ours are SUNBRSL882NF (contractor) and SUNBRSL857CK (electrical).
Who does the roof work?
Some companies sell the job and subcontract the install. Ask whether the crew on your roof works for the company on the contract.
What are the two warranties?
Workmanship (the installer’s) and product (the manufacturer’s) are different things. Get both in writing, with the years.
Who handles the paperwork?
That means the permit, the L&I inspection, the utility interconnection application and the sales-tax exemption certificate. If the answer is “you do,” keep looking.
How did you size this?
In Washington, a system sized to your actual usage beats an oversized one, because unused net-metering credits reset every year. An installer who pushes a bigger system than your bills support is selling panels, not savings.
We’re happy to be compared on all five

Home solar FAQs
The questions Washington homeowners ask us most, answered plainly.
It depends on system size, roof type and whether you add a battery, so we quote every home individually. Washington makes the math simpler than most states: there is no sales tax on the equipment or the installation labor for systems up to 100 kW through 2029, and there is no state rebate or credit to apply for afterward. Our Washington solar panel guide breaks cost down by system size.
No. Washington has no state income-tax credit and no state cash rebate for solar. What Washington does have is a 100% sales-tax exemption on systems up to 100 kW (through 2029) and net metering under RCW 80.60. The federal residential credit ended for systems placed in service after December 31, 2025. The full list is on our Washington incentives page.
Yes. Panels produce from daylight, not heat, and Southwest Washington summers are long and clear. Net metering carries your summer surplus into the dark months as credits, which is why we size systems to your annual usage rather than to a single month. The one date to know is March 31, when unused credits reset.
Yes, all of it: the county or city solar permit, the electrical permit and inspection (Washington L&I, or the City of Vancouver inside its city limits), the interconnection application with Clark Public Utilities, Cowlitz PUD, Skamania PUD or Klickitat PUD, and the sales-tax exemption certificate.
Two to three days on your roof. Start to finish, including permits and the utility’s meter swap, plan on eight to twelve weeks in Clark County. In our experience, the county permit takes about two to six weeks, most often around four. Clark Public Utilities usually processes the interconnection application within four working days and installs the net meter within about five working days after approval.
Sometimes. Our crews are based in Washougal, so we take select projects farther out, usually larger systems or referrals. Call 360-313-7190 and we’ll tell you straight whether we can do yours.
You get app-based monitoring for your system (Enphase or SolarEdge, depending on the equipment in your design), our 10-year workmanship warranty and a local phone number that reaches the people who installed it.
