Western Washington Solar,
Done Right.

LiDAR-Precision Design

We use LiDAR data and aerial imagery to model your roof before a single panel is ordered, so every shading angle and every square foot is accounted for in your custom design. That’s how every Western Washington solar installation from Solphos starts — with data, not guesswork. See how our solar design process works →

Zero Commission Pricing

Most solar companies pay sales reps 20–30% of your project cost, but we don’t. As a result, real savings go straight to you — not into someone else’s commission check. See our full cost breakdown →

Built for the PNW

Solphos was founded in Western Washington and designed specifically for our climate, so we know how to maximize solar production year-round — even through our famously cloudy winters.

“Highly recommend this company. They upgraded our electric panel and installed our wall charger for EV. Very nice to work with. Work was done on time and as promised. The price was fair and reasonable.”

Google Review

“We had an amazing experience working with Solphos for our solar battery backup installation. Trevor, Brian and their team went above and beyond, traveling a long distance to ensure everything was done perfectly. Their professionalism, expertise, and attention to detail were top-notch. The installation process was smooth, and they took the time to explain everything thoroughly. Now, we have a reliable backup system, and we couldn’t be happier! If you’re looking for high-quality solar services, this is the company to trust. Highly recommend!”
