Carson, WA Solar Installers: Solar Panel Installation Since 2010
Sunbridge Solar installs home solar in Carson and up the Wind River valley. Carson is unincorporated Skamania County, so we file the county building permit through Cloudpermit, pull the Washington L&I electrical permit, file the Skamania PUD interconnection, and put the panels on in two to three days.
- Installing since 2010
- L&I registered, bonded & insured
- 10-yr workmanship · 25-yr product warranties
- 2–3 days on site
Who installs solar in Carson, WA?
Sunbridge Solar does. Our own crew comes up Highway 14 from Washougal. We are a Southwest Washington company, not a national sales operation that subcontracts the roof work, and the wooded acreage up the Wind River is the kind of property we design for most.
- Registered, bonded and insured in Washington. Contractor registration SUNBRSL882NF and electrical contractor license SUNBRSL857CK, both active with the Department of Labor & Industries.
- A track record you can look up. We are a licensed Washington contractor with more than 120 permitted installs in Clark County’s public records since 2017, and we install in Skamania County under the same license, the same crew and the same two warranties, including properties that needed a National Scenic Area land use application, which we have filed more than once.
- Two warranties, kept separate on purpose. Ten years on our workmanship, 25 years on the panels and equipment from the manufacturer.
- No-pressure sales. A written quote, then the decision is yours.

Which parts of Carson do you serve?
All of them, and in Carson the address matters more than it does almost anywhere else we work. The Carson townsite is one of the National Scenic Area’s thirteen urban areas, which the Columbia River Gorge Commission says are not subject to scenic-area rules. But a lot of what carries a Carson address sits outside that boundary, in the General Management Area, where a scenic-area land use review comes before the building permit. We check the parcel before we quote, because the two are very different projects.
Inside the Carson urban area
County building permit + L&I electrical, no scenic-area review
- The Carson townsite
- Carson Hot Springs
- Along Highway 14
- Lower Wind River Road
Good to know: Carson is unincorporated, so there is no city hall in the loop, the Skamania County Building Division issues the permit, and applications go through Cloudpermit, which the County notes does not work on a phone. We do the filing.
Wind River addresses in the county
General Management Area, scenic-area review first
- Up the Wind River
- Toward Stabler
- Wind Mountain
- Dog Mountain
- Toward Home Valley

Is your Carson home a good candidate for solar?
Most Carson homes are. Four things decide it: the roof (its direction, its pitch and how much life it has left) the shade on it, the size of your electrical service, and how much power you actually use. None of them depend on your zip code, and all four get checked on the first visit, before anyone talks about price.
Usually a yes
What we look for
- A roof plane facing south, east or west that the trees leave clear for most of the day.
- A composition or metal roof with ten or more years left. The panels are warrantied for 25, so the roof under them should not be the thing that fails first.
- A 200-amp service, or an electrical panel with room for a solar breaker.
- A bill worth cutting. A heat pump, an EV, a well pump or a shop is usually what puts a home in the middle of the 4 to 10 kilowatts we install most.
Still worth a look
None of these is an automatic no
- A shaded or wrong-facing roof. A ground mount or a shop roof often out-produces it, and the trench goes in the quote rather than turning up later.
- An older 100-amp panel. We check it on the first visit and price any upgrade in writing before you sign anything.
- A roof near the end of its life. We will tell you to replace it first rather than charge you to take the panels off and put them back.
- An HOA. Washington law (RCW 64.38.055) stops an outright ban; reasonable rules on placement and appearance go into the design from the start.
The only way to know for certain is to have someone look. We map a year of shade, check the service panel, size the system to your own Skamania PUD bills rather than to the roof, and put a written number in front of you. No charge and no obligation.
What does a solar installer charge in Carson?
The price depends on system size, your roof and whether you add a battery, not on your zip code. Carson properties tend to carry more load than a town lot: a well, a shop, a heat pump, sometimes a hot tub, which pushes a system toward the top of the 4 to 10 kilowatts we install most. The other variable here is the trees, and whether the panels end up on the house at all. Two things keep a Carson quote simple:
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). One exemption certificate at purchase, filed by us.
No rebate to chase
Skamania PUD does not offer a solar rebate and Washington has no state credit, so the number on the quote is the number you pay. The federal residential credit ended for systems placed in service after December 31, 2025. See what changed.
For cost by system size, run your bill through the Washington solar calculator or read our Southwest Washington solar cost guide. Then request a written quote.

What permits does a Carson solar install need?
Two inside the Carson urban area, and possibly a third outside it. Skamania County issues the building permit (Carson is unincorporated, so there is no city permit) and Washington L&I issues the electrical permit. Outside the urban area, a National Scenic Area land use review comes before the building permit.
Skamania County building permit
Filed through Cloudpermit, solar listed as a permit type
- Site plan and roof plan showing the array, fire-access pathways and clearances
- Electrical plan with rapid shutdown and system labeling
- Manufacturer spec sheets for the panels, inverter and racking
- Structural engineering when the roof or the array calls for it
- A ground mount is the same building permit with a different plan set, and more scrutiny outside the urban area
Skamania County Building Division, 170 NW Vancouver Avenue, Stevenson, (509) 427-3925. The County says building permits are currently running a minimum of six to eight weeks after submittal, the longest published review anywhere we work, which is why we file early and give you a real date rather than an optimistic one.
Washington L&I electrical permit
Skamania County does not issue electrical permits
- The County states that electrical work must be permitted and inspected through Washington L&I
- We pull it under our own electrical contractor license and schedule the inspection
- The passed inspection goes to Skamania PUD to start your interconnection
Outside the urban area? Skamania County says almost all structural development in the National Scenic Area needs a land use review, approved before the building permit, and publishes three to four months for expedited applications and seven to nine months otherwise. County code also requires development to be visually subordinate as seen from key viewing areas, and exteriors seen from them to be nonreflective or of low reflectivity. We have filed these applications more than once, and we tell you which project you have before you sign anything.

How does Skamania PUD net metering work in Carson?
Every home in Carson is on Skamania County PUD, whose own office is in Carson, and the PUD net-meters systems up to 100 kW. The power you send to the grid is banked as kilowatt-hour credits against your own later use; the summer surplus carries you through the dark months.
The Skamania PUD process
What happens after the electrical inspection
- Tier 1 (single-phase, 25 kW or less): $200 application fee, expedited process
- Tier 2 (up to 100 kW): $200 plus $10 per kW over 25 kW, capped at $950, included in your price and filed by us
- The PUD makes its best effort to approve or deny a complete application within 20 business days
- Unused credits go to the utility on April 30. Skamania runs a May 1 to April 30 net metering year, a month later than the state default
No PUD solar rebate. You must interconnect and operate within one year of approval or the application expires. Net metering contact: (509) 427-5126.
Why we size to your usage, not your roof
The April 30 reset changes the math
Surplus you bank in July is worth full value in January, but anything still unused on April 30 goes to the utility without compensation. So we size a Carson system to a year of your actual bills rather than to every square foot of south-facing roof. An oversized array looks impressive and gives value back to the PUD.
Our post on Washington net metering explains the math.
Checked September 2026. Source: Skamania County PUD net metering information and interconnection standards; RCW 80.60.030 for the state default; RCW 80.60.030.
Does solar work up the Wind River valley?
Often, yes, but Carson is the one place on our list where we tell people the house roof may not be the answer. At around five hundred feet, tucked between Wind Mountain and the Gifford Pinchot, the timber is the design problem, not the weather.
The trees
Mapped over a year, not guessed at from the driveway
Second-growth Douglas fir grows tall and it grows on all sides. A roof that looks open in July can lose the winter sun entirely to a stand on the south side, and winter is exactly when your credits are being spent rather than banked. We map a year of shade on the actual roof planes before we size anything, and if the house roof does not work we say so rather than selling you a system that underperforms quietly.
The ground mount or the shop roof
Usually the better answer on Wind River acreage
On acreage there is almost always a clear corner, and a ground mount in it will out-produce a shaded roof by a wide margin. A shop or barn roof is the other option. Both add a trench or a run back to the main panel, which we price in writing up front rather than discovering later. Outside the urban area a ground mount also draws more scenic-area scrutiny than a roof array, which is a scheduling question we raise on the first visit. A battery for the well pump and the freezer is the add-on people up here ask about most.
Panels run on daylight, not heat. A cool, bright Carson afternoon is a good solar afternoon, and the rain keeps the panels clean.
How long does a Carson solar install take, start to finish?
The panels go on in two to three days. Start to finish, from first call to switch-on, plan on fourteen to eighteen weeks.
Consultation, design and a written quote
Your roof, your outbuildings, a year of shade on the actual planes, which side of the urban-area line the parcel is on, and a year of your electric bills, then system size, equipment, warranty terms and price on one page.
Permits, install and inspection
The Skamania County building permit through Cloudpermit plus the L&I electrical permit, then two to three days on site, then the electrical inspection.
Utility interconnection and switch-on
Skamania PUD reviews the interconnection application, its published target is 20 business days on a complete application, and sets the net meter. Then you switch it on.
How does Sunbridge Solar compare to a national solar company in Carson?
The panels are the same. What differs is who does the work. Most national companies that advertise in Carson sell the system and subcontract the roof and the wiring, so the people who quote the job are not the people who install it. Sunbridge Solar designs, permits and installs with our own crew, under our own Washington electrical license.
Sunbridge Solar
One company from the site visit to the warranty call
- Our own crew, our own licenses. Contractor registration SUNBRSL882NF and electrical contractor license SUNBRSL857CK. The install is not handed to a subcontractor.
- We do the paperwork. We pull the Skamania County building permit and the L&I electrical permit and file the Skamania PUD interconnection ourselves.
- Two warranties, both in writing. Ten years on our workmanship, 25 years on the panels and equipment.
- A local address. 421 C Street in Washougal, the same people answer the phone in year eight.
Checking a national quote
Four things worth confirming in writing
- Whose crew is on the roof, the company on the contract, or a subcontractor hired for the day?
- Whose electrical license the permit is pulled under, and who meets the L&I inspector.
- Who files the Skamania PUD interconnection and follows it up, or whether that is left to you.
- Whether the price is a cash price or a financed one with dealer fees rolled into it.
How do I choose among solar companies in Carson?
Carson gets pitched by companies from Portland and Vancouver that have never filed a Skamania County permit, let alone a scenic-area application, and some of the national ones sell here and subcontract the roof work. Four questions separate them 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 and SUNBRSL857CK.
Who does the roof work?
Ask whether the crew on your roof works for the company on the contract. Ours does, and it drives here from Washougal.
What are the two warranties?
Workmanship and product are different things. Get both in writing, with the years.
How did you size this?
Skamania PUD credits reset every April 30, so an oversized system gives value back to the utility. An installer who pushes a bigger array than your bills support is selling panels, not savings.

Carson solar FAQs
The questions Carson 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. There is no sales tax on the equipment or labor for systems up to 100 kW through 2029, and no rebate to apply for afterward. Run your bill through our Washington solar calculator for a first number.
Often, yes, but the panels may not belong on the house. Between the elevation and the second-growth fir, a shaded roof can lose the winter sun that matters most, while a ground mount in a clear corner of the property produces year-round. We map a year of shade before we answer. Our Washington solar guide covers what to expect.
Yes. Carson is unincorporated, so the building permit comes from the Skamania County Building Division through Cloudpermit, there is no city permit, plus an electrical permit from Washington L&I. The County publishes a six-to-eight-week minimum on building permits. We prepare and submit all of it.
It depends on the parcel. The Carson townsite is one of the thirteen urban areas the Columbia River Gorge Commission describes as not subject to National Scenic Area rules, but much of what carries a Carson address sits outside that boundary in the General Management Area. There, Skamania County says almost all structural development needs a scenic-area land use review approved before the building permit (three to four months expedited, seven to nine otherwise) and county code requires development to be visually subordinate as seen from key viewing areas, with exteriors seen from them nonreflective or of low reflectivity. In our experience that has meant an inspector assessing an array’s reflectivity from the Oregon side of the river. We have filed these applications more than once, and we check your parcel before we quote.
Not in cash, in kilowatt-hour credits at full value against your own later use. Skamania PUD net-meters systems up to 100 kW and runs a May 1 to April 30 net metering year, so unused credits go to the utility on April 30 rather than the March 31 the state uses elsewhere. The interconnection fee starts at $200 and we include it in your price.
Yes, and on Wind River acreage it is often the better answer. A ground mount or a shop roof uses the same county building permit with a different plan set. We price the trench or the run back to the main panel up front, and outside the urban area we factor the extra scenic-area scrutiny a ground mount draws into the schedule.
The panels are the same; the crew is not. We design, permit and install with our own crew under our own Washington electrical license (SUNBRSL857CK), file the Skamania County building permit and the L&I electrical permit ourselves, handle the Skamania PUD interconnection, and answer the warranty call from our shop in Washougal. Before you sign with anyone, confirm whose crew will be on the roof and whose license the permit is pulled under.
Two to three days on your roof. Start to finish, plan on fourteen to eighteen weeks, Skamania County publishes a six-to-eight-week minimum on building permits, which is the long pole. Outside the Carson urban area, the National Scenic Area review comes on top of that.
