Menlo Park gets meaningful winter rainfall but runs dry from May through October — six months where pollen, Bay Area dust, and bird activity accumulate on panel glass with no natural cleaning. Proximity to Bayfront Park and the marsh corridor means heavier bird traffic for many properties. Studies consistently show 15 to 25 percent output loss from dirty panels in dry California conditions, and concentrated bird droppings create shading effects that degrade the output of the entire string — not just the panels they land on directly.
Tap water leaves calcium and magnesium deposits on panel glass with every wash — those mineral spots reduce light transmission and etch the surface over time. We use deionized water that leaves no residue, paired with soft brushes rated for glass. No chemicals that affect anti-reflective coatings, no abrasive materials that scratch the surface.
The highest-return timing for solar panel cleaning in Menlo Park is late spring — after the peninsula pollen season clears and before the long dry summer when panels carry peak load. A clean array heading into summer recovers output during the highest-generation months of the year.

Panels inspected before cleaning begins. Soiling type noted — bird droppings, pollen accumulation, dust, or general film each require slightly different dwell time. Cracked or damaged panels flagged before any water is applied.
Panels pre-rinsed with deionized water to loosen dry debris. Droppings and dried pollen softened before brush contact — this reduces the chance of dragging hard particles across the glass surface.
Glass scrubbed with soft brushes rated for panel surfaces. No abrasive pads, no rough materials. Consistent pressure across the panel surface — no circular scrubbing that can create uneven cleaning patterns.
Panels rinsed with deionized water. No mineral residue left behind. Water runs off clear — no spots, no film. Framing and edges wiped if needed to prevent drip lines.
Each panel checked in direct light after rinsing. Any remaining spots or areas with stubborn buildup cleaned a second pass before moving on.
System visually inspected from below — panels should show uniform reflectivity when clean. Any cracked glass, delamination, or mounting issues noticed during cleaning are reported to the homeowner.

Menlo Park's dry season runs roughly May through October — six months of pollen, dust, and bird activity with no rain. Studies consistently show 15 to 25 percent output loss from dirty panels in dry California conditions. Bay-adjacent bird traffic can accelerate soiling and the shading from droppings impacts entire strings, not just individual panels.
Deionized water and soft brushes rated for glass surfaces. Deionized water leaves no mineral spots — tap water leaves calcium and magnesium deposits that reduce light transmission over time. No abrasive brushes, no chemicals that could affect the anti-reflective coating.
Once a year at minimum — typically in late spring before the dry summer production season. Properties near Bayfront Park or the marsh corridor with higher bird activity may benefit from cleaning twice a year.
Yes — panels are cleaned during daylight hours while the system is active. The cleaning process does not require the system to be shut down.
Yes. We work on single and multi-story properties throughout Menlo Park and San Mateo County.
Not when done correctly. Major manufacturers recommend regular cleaning and specify deionized water and soft brushes as the appropriate method. Harsh chemicals and abrasive tools are what void warranties — those are not part of our process.
Yes. Bull Run Exterior Wash LLC is fully licensed and carries general liability insurance on every job.
