San Ramon sits in the Tri-Valley — a region with warm, dry summers and regular east wind events pushing Central Valley dust through Altamont Pass and across the valley floor. Panels in San Ramon accumulate heavier dust loads than coastal Bay Area cities, and the long dry season from late spring through fall means months of accumulation with no rain to clear it. Bird activity from Las Trampas Regional Wilderness and Sycamore Valley Open Space adds organic deposits on top of the dust.
Tap water leaves calcium and magnesium deposits on panel glass with every cleaning — 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.
Late spring — after pollen season and before the dry Tri-Valley summer — is the highest-return timing. Panels heading into the hot summer production season clean are recovering output at the time of year when generation matters most.

Panels inspected before cleaning begins. Soiling type noted — bird droppings, pollen accumulation, dust, or general film each affect dwell time. Cracked or damaged panels flagged before any water is applied.
Panels pre-rinsed with deionized water to loosen dry debris. Tri-Valley dust and dried pollen softened before brush contact — prevents dragging hard particles across the glass surface.
Glass scrubbed with soft brushes rated for panel surfaces. No abrasive pads. Consistent pressure across the panel surface — no circular scrubbing that creates 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 stubborn buildup cleaned a second pass before moving on.
System visually inspected from below — clean panels show uniform reflectivity. Any cracked glass, delamination, or mounting issues noticed during cleaning are reported to the homeowner.

San Ramon's Tri-Valley location means panels face regular east wind events pushing Central Valley dust through Altamont Pass, plus bird activity from surrounding open space. Long dry summers mean months of accumulation with no rain to clear it.
Studies consistently show 15 to 25 percent output loss from dirty panels in dry California conditions. Concentrated bird dropping shading affects entire strings — not just individual panels.
Deionized water and soft brushes rated for glass. No mineral residue, no abrasive materials, no chemicals that affect anti-reflective coatings.
Once a year at minimum — late spring before the dry summer. Properties near open grassland should consider twice a year.
Not when done correctly. Major manufacturers specify deionized water and soft brushes as the appropriate method. We don't use anything that voids warranties.
