5 Best Solar Panel Providers in Seattle (2026)

Independently ranked by our review of ratings, reviews and reputation · How we chose

By Brad Smith, Home Services Expert · ✓ Data verified August 2026 · 8 min read

Seattle's cloudy reputation doesn't stop solar from paying off, homeowners here still report offsetting most or all of their electric bill, but choosing the right solar panel provider in Seattle decides whether that promise holds up years later. Between them these companies have logged over 1,550 Google reviews, and four sit at 4.8 stars or higher, so the real question is who backs up the install with responsive service after the panels go up.

Short answer: Galaxy Electric holds a perfect 5.0 rating across 268 reviews for electrical and solar work, while Northwest Electric and Solar (4.9, 312 reviews) and Sunergy Systems (4.9, 249 reviews) are both established, Tesla-certified solar installers. Omnidian (4.3, 582 reviews) is a separate maintenance and warranty-service provider, not an installer, and its reviews are notably more mixed.

Northwest Electric and Solar

4.9312 Google reviews

Northwest Electric and Solar is a Washington State full-service electrical contractor specializing in solar panel installation, Tesla Powerwall battery systems and EV charger installation.

Our take: A strong, well-reviewed pick particularly for a system that includes Tesla Powerwall battery backup or a roof type that limits your installer options. Confirm the final quote in writing before work begins given the one reviewer's pricing discrepancy.

Omnidian

4.3582 Google reviews

Omnidian is a Seattle-based company providing performance assurance and warranty maintenance services for existing solar systems, not new installations. It's important to flag this clearly: Omnidian is often assigned to homeowners as a third-party warranty or maintenance provider after their original installer sells the account, rather than a company homeowners choose directly, and its review pattern reflects that.

What people praise

Deepest review base on this list at 582 reviews

Worth knowing

Multiple reviewers describe multi-month or multi-year delays getting failed parts replaced under warranty
Several 1-star reviews describe difficulty reaching a resolution for roof leaks or battery issues tied to solar installations

Our take: Not a company to choose for a new installation, since it provides ongoing maintenance and warranty service, often assigned rather than selected. If you're evaluating a solar company that partners with Omnidian for post-install support, the review pattern here is worth factoring into that decision.

How we score

Every number on this page comes from public Google data on the date shown, not from opinion or payment. Rating is the company’s live Google star average. Review volume measures how many customers have rated them, ranked against other Seattle solar companies. Confidence weighs the rating by that volume, so a 5.0 from 268 reviewers carries more weight than a perfect score from a handful. Recency reflects how recently customers are still leaving reviews. No company can pay to change these numbers.

How much does solar installation cost in Seattle? (2026)

Pricing for a residential solar system depends heavily on system size, roof type and complexity, and whether battery storage like a Tesla Powerwall is included. No independently verifiable price list was available across these companies, so get a detailed written quote and compare rebate and financing options before committing.

What to ask before you hire a solar installer

Are you a Tesla Certified Installer, if a Powerwall is part of the plan?
What warranty do you offer, and who handles service if something fails later?
Can you accommodate my specific roof type?
Is the final quote guaranteed in writing, with no changes after signing?
What rebates or financing options are currently available?
How long does installation typically take from signing to activation?

Frequently asked questions

How did you choose these solar companies?

We started from every solar panel provider in Seattle with a public Google presence, then ranked by rating, review volume, consistency and recency. See How we score above.

Are these rankings paid?

No. Rankings come from the public Google data in the scorecard. A business can pay to be a Featured Partner, which adds a badge and top placement, but that never changes another business’s score or position on the underlying data.

How often is this updated?

The data carries a verified date (August 2026 on this page). We refresh listings periodically so ratings and review counts stay current.

Does solar actually work well in cloudy Seattle?

Yes, according to reviewers on this page. One SolTerra customer reported their system outproduced its 25-year design estimate in its first year, even accounting for Seattle’s weather, and multiple reviewers across these companies describe significant reductions in their electric bills.

What is Omnidian, and should I choose them for my installation?

Omnidian provides ongoing maintenance and warranty service for existing solar systems rather than new installations. Homeowners are often connected to Omnidian after their original installer sells the account, rather than choosing them directly, and the review pattern shows more mixed experiences with response times.

The bottom line

Galaxy Electric and Northwest Electric and Solar both carry the strongest overall track records for a new solar installation, with Sunergy Systems a close, locally rooted alternative. Whichever you choose, get the warranty and service terms in writing before signing.
