Learn – How Solar Works
Does Solar Work in the Pacific Northwest?
Yes—absolutely.
Western Washington may have more gray days than Arizona or California, but solar remains a dependable and efficient energy solution here. Why?
- Long summer days mean high production from May to September
- Cooler temperatures actually improve solar panel efficiency
- Modern panel technology captures light even on cloudy days
- Net metering lets you bank credits during high-production months for use in winter
Seattle, Bellingham, and other PNW cities still get enough annual solar radiation to make solar a smart, cost-saving investment.
Local Solar Myths, Busted
“There’s not enough sun here.”
False. Germany—one of the world’s top solar markets for many years—gets less sun than Bellingham.
“Panels only work when it’s hot out.”
Nope. A solar panel’s output will depend on the intensity of light, along with the air temperature. In fact, the efficiency increases in cooler temperatures.
“Solar won’t save me money here.”
With available incentives, net metering, zero sales tax, and taking advantage of low-interest solar financing, homes with good sun are usually paying less on their electricity bills than without solar. Paying for the system out-of-pocket means even better economics. As electricity rates continue to climb in our area, savings from solar are only going to increase.
Custom Solar Design for Our Region
We focus on the design details to ensure optimum performance and value. Our technical design approach combines decades of expertise with ongoing education and best-practice collaboration through Amicus Solar Cooperative, connecting us with the most experienced solar companies in the country. We leverage cutting-edge satellite imagery, LIDAR technology, and precise on-site measurements to deliver reliable, high-performing solar systems throughout Northwest Washington. Each system design considers:
- E30+ years of local weather data specific to your ZIP code
- ESite-specific shading from trees, nearby buildings, or other obstructions
- ERoof orientation, pitch, condition, and type
- ELocal and state building codes
- ELong-term production, not just ideal days/seasons
We use satellite mapping, on-site analysis, and 20 years of local experience to deliver reliable, high-performing systems for Northwest Washington.
What Makes a Good Site for Solar?
While every home or building is different, here’s what helps:
- ^Southern, western, or eastern roof exposure
- ^Minimal shading from trees or nearby structures
- ^A roof in good condition with enough space for panels
- ^Or open land for a ground-mounted system
Not sure if your property is solar-ready? We offer free site assessments to help you find out.
Solar + Battery Backup = Resilience
With battery storage, you can store your own solar power and use it during outages—something more and more PNW residents are looking for as storms and grid demand increase. Learn more on our Battery Backup page.
