Dirty solar panels don’t just look bad—they cost you real money. When dust, pollen, and debris coat your panels, they block sunlight from reaching the cells that generate your power.
Studies show dirty panels can lose 15-35% of their energy production. For a commercial operation, that’s thousands in lost savings every month. Google’s own case study found their solar output doubled after professional cleaning.
Clean panels mean maximum energy generation, lower utility bills, and faster return on your solar investment. You didn’t spend all that money on solar to watch it underperform because of dirt.
We at All Seasons Window Cleaning Inc. have been keeping Valle Vista’s commercial solar systems running at peak efficiency for years. We’re fully bonded and insured, so you’re completely covered.
We serve the entire region including Valle Vista, Santa Clarita Valley, San Fernando Valley, and surrounding areas. Our repeat commercial clients trust us because we show up on time, use professional equipment, and get results.
Unlike general cleaning companies, we specialize in solar panel maintenance. We understand how California’s unique climate challenges—from wildfire ash to coastal salt—impact your panels’ performance.
First, we inspect your entire solar array to assess soil buildup and identify any potential issues. This helps us determine the best cleaning approach and spot problems before they become expensive repairs.
Next, we use deionized water and specialized rotating brushes designed specifically for solar panels. No harsh chemicals that could void your warranty—just pure water that leaves zero mineral deposits or streaks.
Finally, we perform a thorough rinse and quality check to ensure every panel is spotless. You’ll see the difference immediately in both appearance and energy output. Most clients notice improved performance within days.

Our commercial solar cleaning covers everything from small rooftop installations to large-scale solar farms and carport systems. We handle ground-mounted arrays, rooftop panels, and hard-to-reach installations up to three stories.
Valle Vista’s dry climate and seasonal dust storms create unique challenges for solar panels. Spring pollen creates sticky films that attract more dirt. Summer dust coats panels quickly. Wildfire season brings ash that hardens onto glass surfaces.
We recommend cleaning every 3-6 months for most Valle Vista commercial installations, though high-dust environments may need more frequent service. Our maintenance plans keep your system performing year-round while protecting your warranty requirements.
Studies consistently show dirty solar panels lose 15-25% of their energy production capability, with some cases reaching 35% loss in heavily soiled conditions. Google’s own research found their solar output doubled after cleaning panels that hadn’t been maintained for 15 months.
For a commercial operation in Valle Vista, this translates to thousands in lost energy savings annually. A 100kW system losing 20% efficiency could cost you $3,000-5,000 per year in reduced performance.
The efficiency loss happens gradually, so many businesses don’t realize how much money they’re leaving on the table until after professional cleaning restores full output.
No, rain actually makes solar panel soiling worse in many cases. Rainwater in California contains airborne pollutants, dust particles, and minerals that leave deposits when the water evaporates.
Rain can also harden existing dirt and debris onto panel surfaces, making it more difficult to remove later. In Valle Vista’s semi-arid climate, light rainfall often just creates muddy streaks rather than cleaning panels.
Professional cleaning with deionized water removes all contaminants without leaving mineral deposits. Think of it like your car windshield—rain doesn’t keep it clean, and your solar panels face the same environmental challenges.
Most commercial solar installations in Valle Vista should be cleaned every 3-6 months for optimal performance. However, the frequency depends on your specific location and environmental factors.
Properties near agricultural areas, construction zones, or high-traffic roads may need cleaning every 2-3 months due to increased dust and debris. Coastal properties deal with salt residue that requires more frequent attention.
We assess each installation individually and recommend a maintenance schedule based on your panels’ exposure, tilt angle, and local conditions. Regular cleaning every 4 months typically provides the best balance of performance and cost-effectiveness.
Yes, many solar panel manufacturers require proof of regular cleaning and maintenance to honor warranty claims. Failing to maintain your panels properly can void coverage for performance guarantees and equipment defects.
Most commercial solar warranties specify cleaning requirements, though the exact terms vary by manufacturer. Some require cleaning every 6 months, others annually, and many require professional documentation of maintenance.
We provide detailed service reports after each cleaning that satisfy manufacturer requirements. This documentation protects your warranty coverage and proves due diligence if you ever need to file a claim.
Professional solar cleaning uses deionized water that leaves zero mineral deposits, while tap water creates spots and scaling that actually reduce panel efficiency over time. We also use specialized rotating brushes designed specifically for solar glass.
Safety is another major factor—commercial solar installations often require working at height on sloped roofs. Our team is properly insured and equipped with safety gear. One slip could result in serious injury or expensive roof damage.
Most importantly, improper cleaning techniques can scratch panel surfaces or damage seals, potentially voiding warranties. Professional cleaning protects your investment while maximizing performance and longevity.
You’ll typically see improved energy output within 24-48 hours after professional cleaning, once your monitoring system updates with new production data. The improvement is often dramatic—many clients see 20-30% increases in daily energy generation.
The exact improvement depends on how dirty your panels were before cleaning. Panels that haven’t been cleaned in over a year often show the most significant gains, sometimes doubling their output like in Google’s documented case study.
Most Valle Vista commercial clients notice lower utility bills within the first month after cleaning, as their solar systems offset more grid electricity. The investment in professional cleaning typically pays for itself within 2-3 months through increased energy production.
