Your solar panels are working harder than they should. Dust, bird droppings, and California’s notorious wildfire ash don’t just make your panels look bad—they’re stealing your energy production every single day.
When panels are clean, sunlight hits every cell. When they’re dirty, you’re paying for electricity you shouldn’t need to buy. Studies show dirty panels can lose 25-35% of their efficiency, turning your smart investment into an underperforming expense.
Clean panels mean lower utility bills, better return on investment, and the energy output you were promised when you went solar. That’s what proper maintenance delivers.
We’ve been serving El Sobrante’s commercial properties with specialized cleaning services for years. We understand that your solar installation represents a significant investment in your business’s future.
El Sobrante’s location in Contra Costa County means your panels face unique challenges—from Bay Area pollution to seasonal wildfire ash that can coat arrays in a matter of hours. We’ve cleaned panels on everything from small commercial rooftops to large industrial facilities throughout the region.
Our team knows how to safely and effectively restore your panels to peak performance without voiding warranties or causing damage. When your energy production matters to your bottom line, experience matters.
We start with a comprehensive assessment of your solar array and current energy output data. This helps us understand exactly how much efficiency you’ve lost and what results you can expect.
Our cleaning process uses deionized water and specialized soft-brush equipment designed specifically for solar panels. No harsh chemicals, no high-pressure washing that can damage seals, and no shortcuts that put your warranty at risk.
We clean during optimal times—early morning or late afternoon—to avoid thermal shock and ensure panels are cool enough for safe cleaning. Every panel is thoroughly cleaned, rinsed, and inspected before we consider the job complete. You’ll receive documentation of the work performed and recommendations for ongoing maintenance.

We handle all types of commercial solar installations throughout El Sobrante and Contra Costa County. Ground-mount arrays, rooftop systems, carport installations, and agricultural solar—if it generates power for your business, we can clean it properly.
El Sobrante’s industrial and commercial properties face specific challenges. The area’s proximity to major highways means more particulate buildup. Local businesses from healthcare facilities like Kaiser Permanente to retail operations deal with different types of soiling depending on their location and surrounding activities.
Our service includes panel cleaning, inverter area maintenance, and basic system inspection. We work around your business schedule and can coordinate with your solar installer or maintenance provider to ensure comprehensive care of your investment.
Most commercial solar installations in El Sobrante benefit from cleaning every 6-12 months, but your specific needs depend on your location and environmental factors. Properties near busy roads or industrial areas may need more frequent cleaning due to higher pollution levels.
El Sobrante’s location means you’ll deal with seasonal challenges like wildfire ash, which can coat panels quickly and dramatically reduce output. We recommend monitoring your energy production and scheduling cleaning when you notice a drop in efficiency, typically 2-4 times per year for most commercial properties.
The investment in regular cleaning pays for itself through improved energy production. When panels lose 25-35% efficiency due to soiling, the cost of cleaning is minimal compared to the energy losses you’re experiencing.
Professional cleaning with proper techniques and equipment will not void your solar panel warranty. In fact, most manufacturers require regular maintenance to keep warranties valid, and some specifically recommend professional cleaning every 6 months.
We use only manufacturer-approved cleaning methods—soft brushes, deionized water, and no harsh chemicals or high-pressure washing. Our team is trained in proper safety procedures and panel handling to prevent any damage during the cleaning process.
We provide documentation of our cleaning service and methods used, which can be valuable for warranty claims or insurance purposes. Many of our commercial clients use our service reports as part of their regular maintenance documentation.
Rain helps, but it’s not sufficient for maintaining optimal solar panel performance. California’s rainfall patterns mean long dry periods where dust, pollen, and debris accumulate without natural washing.
Even when it does rain, the water often leaves behind mineral deposits and doesn’t remove sticky substances like bird droppings or tree sap. Rain can actually make some soiling worse by creating mud from dust or leaving water spots that reduce light transmission.
Professional cleaning removes all types of buildup and uses deionized water that doesn’t leave mineral deposits. The difference in energy output between rain-cleaned and professionally cleaned panels is significant enough to justify the service cost.
Commercial solar cleaning requires specialized equipment, safety protocols, and expertise that residential cleaning doesn’t demand. Commercial installations are typically larger, often in hard-to-reach locations, and require coordination with business operations.
We use commercial-grade equipment including boom lifts, water-fed pole systems, and sometimes robotic cleaners for large ground-mount arrays. Safety is paramount with OSHA-compliant procedures for working at heights and around electrical equipment.
Commercial cleaning also involves more detailed reporting and documentation. You need records for insurance, warranty compliance, and energy production tracking. We provide comprehensive service reports and can coordinate with your facility management team or solar maintenance provider.
Commercial solar cleaning costs vary based on system size, panel accessibility, and cleaning frequency. Most commercial properties invest between $500-$3,000 per cleaning, depending on the installation size and complexity.
The cost is minimal compared to the energy losses from dirty panels. If your system is losing 25% efficiency due to soiling, the monthly energy losses likely exceed the cost of quarterly cleaning. Most businesses find that regular cleaning pays for itself within the first month through improved energy production.
We provide detailed quotes based on your specific installation and can work with you to develop a maintenance schedule that fits your budget and maximizes your return on investment. Many clients find that regular scheduled cleanings are more cost-effective than emergency cleanings when production drops significantly.
Absolutely. We understand that your business operations can’t stop for panel cleaning, so we work around your schedule and operational needs. Many commercial cleanings are performed during off-hours, weekends, or scheduled maintenance periods.
For businesses that operate 24/7, we coordinate with your facility management to minimize any disruption. Most cleaning can be performed without affecting your daily operations, and we’ll communicate with your team throughout the process.
We can also coordinate with your solar installer, maintenance provider, or facility management company to ensure comprehensive care of your solar investment. Our goal is to maximize your energy production while minimizing any impact on your business operations.
