Do Solar Panels Work in Oregon’s Cloudy Weather?

Raptor Solar has helped homeowners across Oregon navigate this exact question, and chances are you’ve wondered: do solar panels even work here with all the clouds? It’s a fair question. With our grey skies and rainy seasons, it’s natural to be skeptical. But the truth might surprise you—solar is not only viable in Oregon, it’s smart. Here's why.

Cloudy Doesn’t Mean Inefficient
Solar panels don’t need direct sunlight to generate power—they need light, even if it’s diffused. Oregon gets around 140–180 sunny or partly sunny days per year, which is plenty for well-designed solar systems. In fact, some of the most solar-friendly countries in the world—like Germany—get less sun than Portland.

Why Cooler Climates Help Solar
Most people assume hotter is better, but excessive heat can actually reduce panel efficiency. Oregon’s cooler climate helps solar panels operate closer to peak performance year-round. And yes, they even work in the rain and snow, as long as they get light.

You Can Store Solar Energy, Too
With a solar battery (like the Franklin units we install), you can store extra power during the day and use it when the sun isn’t shining. That means you're not just generating energy—you’re gaining independence from the grid, especially during outages or rate hikes.

The Takeaway – Solar Works in Oregon, Period
Despite cloudy days, solar panels work efficiently in Oregon thanks to diffused light, moderate temperatures, and modern tech like batteries. It’s one of the smartest home upgrades a local homeowner can make—especially when it's $0 out of pocket.
