You wouldn’t buy apples from New Zealand when the best ones are grown right here in Yakima.
So why buy solar panels shipped from overseas when some of the highest-rated, most durable panels in the world are manufactured less than 3 hours north of Portland?
At Sunbridge Solar, we are huge proponents of the “Buy Local” movement—not just because it feels good, but because in the solar industry, Washington-made panels are simply better for Washington homes.
In this guide, we’re shining a spotlight on the true heavyweight champion of Pacific Northwest solar manufacturing: Silfab Solar.

Who is Making Solar Panels in Washington?
While many companies claim to be “American Assembled,” very few have the deep roots in our state that Silfab Solar does.
Operating out of state-of-the-art facilities in Bellingham and Burlington, WA, Silfab has become the defining name in North American solar manufacturing. If you’ve been following the local industry, you might remember Itek Energy, the beloved Bellingham manufacturer. Silfab acquired Itek a few years ago, keeping those local jobs alive and injecting massive investment to upgrade the technology.
In 2026, Silfab isn’t just a “local option”—they are a premium option that competes globally on efficiency and durability.
The Star Product: Silfab Solar Panels
Silfab currently produces two main lines that are perfect for our grey, rainy, and occasionally stormy climate.
1. The Silfab Elite (The “Premium” Choice)
This is widely considered one of the highest-efficiency panels manufactured exclusively in the United States.
- Technology: Uses advanced “Back-Contact” technology. By moving the wires to the back of the cell, the front is unobstructed, capturing more light. This is crucial for our overcast PNW days where every photon counts.
- Aesthetics: These are the “black-on-black” panels that homeowners love. They look seamless on a roof, blending in rather than standing out like a sore thumb.
- Durability: Rated for extreme wind and snow loads—perfect for the Gorge winds or a heavy Cascade snow event.

2. The Silfab Prime (The “Workhorse”)
Updated for 2026 with N-Type TOPCon technology, the Prime series offers incredible performance at a slightly lower price point.
- Why N-Type? In plain English, “N-Type” silicon is chemically superior to the older “P-Type” standard. It resists light-induced degradation (LID). This means that while older panels might lose 0.5% or 0.7% of their power every year, the Silfab Prime retains its strength much longer, giving you more free electricity in Year 20 than a standard panel would.
- Reliability: Like the Elite, it undergoes rigorous quality control right here in Washington, ensuring every panel that leaves the factory is ready for our weather.
Real-World Proof: The Olympia Fire Station
You don’t have to take our word for it. Look at who else trusts these panels.
In late 2025, the City of Olympia completed a massive solar installation on Fire Station #1. They chose Silfab Solar panels for this critical infrastructure.

Why does this matter to you? Fire stations are “essential facilities.” They cannot afford equipment failure. When the city engineers evaluated the options, they chose Washington-made Silfab panels for their reliability and durability. If they are trusted to power the emergency response for the state capital, they are certainly tough enough for your home in Camas or Gresham.
Is the “Made in WA” Premium Worth It?
Let’s be transparent: A system using Washington-made Silfab panels may cost slightly more upfront than one using generic panels imported from Southeast Asia.
Is it worth the extra investment? We argue yes, for three reasons:
- The “30-Year” Math: Solar is a 3-decade investment. Saving $500 upfront on cheaper panels isn’t worth it if they degrade faster or fail in Year 12. Silfab’s N-Type technology ensures higher production for longer, likely erasing that price difference within the first few years of operation.
- Warranty Logistics: If an imported panel fails in Year 15, you are often chasing a manufacturer in a different time zone (or one that has gone out of business). With Silfab, the warranty is backed by a team right here in Washington.
- Home Value: Buyers in the Pacific Northwest are eco-conscious. Being able to tell a future homebuyer, “These are premium, Washington-made panels,” is a tangible selling point that adds to your home’s narrative and value.
3 Reasons to Choose “Made in WA”
Beyond the technology, there are practical reasons to choose Washington-made equipment.
1. Supply Chain Ethics & Certainty
The global solar supply chain can be murky. By choosing Silfab, you are bypassing concerns about forced labor in overseas regions or shipping delays caused by global conflict. You know exactly where your panels came from and who made them—your neighbors in Skagit and Whatcom counties.
2. Lower Carbon Footprint
Does it make sense to buy an eco-friendly product that was shipped on a diesel-burning cargo ship halfway around the world? By choosing local, you are slashing the “embedded carbon” of your solar system. Your panels didn’t cross an ocean; they took a short truck ride down I-5.
3. Warranty Support You Can Trust
Silfab offers a 25-Year Product and 30-Year Performance Warranty. While many overseas manufacturers offer similar numbers on paper, good luck trying to process a warranty claim with a company headquartered in a different time zone with no US support staff. With Silfab, the support team is local, responsive, and accountable.
How Do They Handle PNW Weather?
This is the big question. We don’t have the blistering sun of Arizona; we have rain, moss, and grey skies.
- Low-Light Performance: Silfab panels are engineered for “low irradiance” environments. They turn on earlier in the morning and stay on later in the evening, squeezing every drop of power out of our shorter winter days.
- Hail & Wind: Rated for heavy mechanical loads (up to 5400 Pa), they can shrug off the windstorms that tear branches off trees in Camas and Washougal.
Frequently Asked Questions (FAQ)
Are Silfab solar panels really made in Washington State?
Yes. Silfab operates two major manufacturing facilities in Washington: one in Bellingham and another in Burlington. While they are a North American company with Canadian roots, the panels installed on your home are likely assembled by workers in Skagit or Whatcom County.
Do Washington-made panels work better in cloudy weather?
Yes. Washington-manufactured panels like the Silfab Elite are specifically engineered for the “low-irradiance” conditions of the Pacific Northwest. They utilize conductive back-sheets and advanced cell chemistry to capture more diffuse light (cloudy sunlight) than standard panels designed for the desert southwest.
Did Silfab buy Itek Energy?
Yes. Several years ago, Silfab acquired Itek Energy, which was a popular Bellingham-based solar manufacturer. Silfab kept the manufacturing footprint in Washington and invested heavily to upgrade the machinery, allowing them to produce the high-efficiency N-Type panels available today.
Are locally made panels more expensive?
They can be slightly more expensive than generic imports from Asia, often adding 5-10% to the total equipment cost. However, most homeowners find this premium is offset by the 30-year performance warranty, higher resale value, and the assurance of ethical labor practices.
What is the warranty on Silfab panels?
As of 2026, Silfab offers a 25-Year Product Warranty (covering workmanship and defects) and a 30-Year Performance Warranty (guaranteeing power output). This is one of the strongest warranties in the industry, backed by their local US operations.
