Solar Power in the Pacific Northwest: A June Tune-Up Guide

The Pacific Northwest may be known for clouds, but June marks the beginning of peak solar season in the PNW. That means it’s the perfect time to clean, inspect, and optimize your system for summer.

Here’s how to prepare your solar panels for strong performance as the sun sticks around longer each day.

What Makes Summer Unique in the Pacific Northwest

While Washington’s climate is milder than desert states, it comes with its own challenges—moss growth, tree pollen, cloudy intervals, and late spring debris. If not addressed, these can reduce your system’s efficiency just when you want it highest.

Pacific Northwest Solar Maintenance Checklist

1. Clean Off Pollen & Tree Debris

June is peak pollen season. A soft rinse can remove the yellow film that dims your panels’ effectiveness.

2. Watch for Moss and Algae

In shaded or damp spots, moss buildup can occur around panels or on roofing. It needs to be cleared quickly to prevent moisture damage.

3. Monitor Your Output

Cloud cover may fluctuate, but your production shouldn’t dip dramatically. Use your monitoring app to ensure consistency.

4. Schedule a Professional System Check

A once-a-year inspection helps ensure all components—from inverters to wiring—are performing properly.
