Dust accumulation can reduce solar output by 30% in just one month, costing a 150-megawatt installation $200,000 annually. Clean panels mean maximum energy production, lower utility bills, and faster return on your solar investment.
Desert conditions in Rancho Mirage create extremely dirty panels, especially after the combination of rain and wind that leaves stubborn residue. Professional cleaning restores your system to peak performance while protecting your expensive equipment from damage.
You invested in solar to save money and reduce your environmental impact. Clean panels deliver on both promises by generating the energy output you were promised when you made that investment.
All Seasons Window Cleaning Inc. brings professional solar cleaning expertise directly to Rancho Mirage businesses. We serve the entire Coachella Valley including Palm Springs, Palm Desert, Cathedral City, and Indian Wells, understanding the unique challenges desert conditions create for solar systems.
We’re fully licensed, insured, and bonded, giving you complete peace of mind when we’re working on your valuable solar investment. Our team uses only professional-grade equipment and deionized water systems that protect your panels while delivering superior cleaning results.
Rancho Mirage’s 80+ gated communities and high-value properties reflect a community that values quality and security. We bring that same commitment to excellence to every commercial solar cleaning project.
We start with a comprehensive assessment of your solar array, identifying problem areas and documenting current conditions with photos. Every service includes a free thermal camera scan to detect hotspots and defective cells early, preventing efficiency loss and costly repairs.
Our cleaning process uses only deionized water and specialized brushes designed specifically for solar panels. This prevents water spots, mineral deposits, and scratches that can damage your panels or void warranties. We never use harsh chemicals or abrasive materials.
After cleaning, we conduct a final inspection and provide before-and-after documentation. We check your panels for signs of corrosion and damage, giving you a complete picture of your system’s health and performance potential.

Our commercial solar cleaning service covers ground-mount installations, rooftop systems, carports, and utility-scale arrays. We’re OSHA safety certified for boom lift cleaning in hard-to-reach areas, ensuring safe access to even the most challenging installations.
Rancho Mirage’s desert environment requires specialized attention. Wildfire season sends soot and ash into the air, creating stubborn residue that layers over panels, while daily dust accumulation blocks crucial sunlight from reaching solar cells.
We offer flexible scheduling including overnight cleaning for retail locations, warehouses, and facilities where daytime operations can’t be interrupted. Our overnight service is perfect for big box stores and busy commercial properties where auto and pedestrian traffic is a concern.
For most commercial installations in Southern California, we recommend scheduling cleaning every 3-6 months. However, concentrated solar systems should be cleaned monthly, while other systems need service twice yearly.
If your business is in an area with heavy air pollution, near construction zones, or experiences frequent dust storms, you may need more frequent cleaning. We recommend cleaning at least once yearly, or more if you live in a dusty area, and monitoring your energy output for drops that indicate cleaning is needed.
MIT experts suggest even a 1% reduction in power from a 150 MW solar project could cause $200,000 in lost revenue annually, and as panels take on more soiling, losses can quickly mount. Globally, a 3-4% reduction in power output from solar plants amounts to losses between $3.3 billion and $5.5 billion.
Studies show dirty panels can lose 15-25% of their energy production capability, and for commercial operations with high energy demands, this drop in performance adds up quickly. The cost of professional cleaning is minimal compared to these potential losses, making regular maintenance a smart business decision.
Looking at your windshield after a rare Southern California rain shower makes it obvious why you can’t depend on rainwater to keep solar panels clean. Rain contains airborne dust particles that settle and attach to the surface after rainwater evaporates, plus calcium and hard water deposits common in Southern California.
It’s important to clean after rain and wind as these two elements together create extremely dirty panels, and according to the National Renewable Energy Laboratory, debris can cause up to 30% loss in solar panel energy production. Rain does not clean solar panels effectively or efficiently, and is not strong or consistent enough to effectively clean your panels.
Many commercial solar installations are located on rooftops or high elevations, and hiring trained professionals prevents unnecessary risks to you or your staff. Solar panel cleaning can be dangerous, and at professional companies safety is the first concern.
We’re trained to clean panels without damaging them, using proper tools like soft brushes, purified water systems, and long-reach cleaners to safely and thoroughly clean every inch of your panels. We use high-quality products specifically designed for safely cleaning solar panels – no corrosive chemicals, only the purest reverse osmosis deionized water fed through extension poles with specialized brushes.
The most effective method uses pure reverse osmosis deionized water to boost photovoltaic production by 20% or more, using specialized equipment and never harmful chemicals or abrasives. We always use tested deionized water to avoid scaling and mineral deposits caused by hard water, and never use harmful chemicals or soaps to protect your solar panel’s warranty.
Water jet cleaning with pure water washes away soiling effectively, as any impurities can leave water spots and deposits. Dry brushing is generally less effective than water and may potentially scratch or damage panels, which is why professional wet cleaning with deionized water delivers superior results while protecting your investment.
We’re able to clean thousands of panels for large-scale solar properties within a short period because we use only the best commercial solar panel cleaning equipment. Residential systems typically take 1-1.5 hours depending on size and crew, while commercial timing depends on the system size and we quote the time when we quote your job.
Using boom lifts, we can wash hundreds of panels within a couple hours, and we use a combination of robots and rotating brushes to complete large projects in a single day. Each job is different based on the system, accessibility and roof style, and we provide free estimates upon request that include realistic timeframes for your specific installation.
