Why it matters
Buildup you can barely see is costing you every sunny day
Your home’s solar system works best when it is clean. Over time, pollen, dust, leaves, bird droppings, and pollution block sunlight and reduce energy production, often without any obvious sign from the ground.
In the Pacific Northwest the pattern is predictable: spring pollen bakes on, summer dust settles, and nine months of drizzle glue it all to the glass. Rain rinses loose dirt but never removes the film. One annual pure-water cleaning resets the clock.
The result is not cosmetic. Our clients see the difference on their own monitoring apps, and every cleaning is documented with before and after photos, so the change is on the record.

Questions
Asked and answered
Once a year is the right baseline for most Portland-area homes, ideally after spring pollen season. If your array sits near trees, a highway, or open fields, twice a year keeps output consistently high.
We use soft, panel-rated brushes and pure de-ionized water: no chemicals, no abrasive pressure. This is the maintenance approach panel manufacturers recommend.
Never on the panels. Most residential work is done with water-fed poles from ladders or the ground. When roof access is required, we use proper footing and safety equipment, and we plan access before we start.
