Solar Panel Cleaning
Solar panels generate electricity by absorbing sunlight through photovoltaic cells. When debris accumulates on the glass surface, it prevents sunlight from fully reaching the solar cells. Studies show that dirty solar panels can lose 15–30% of their energy output.
Professional solar panel cleaning restores sunlight exposure so your system can operate at optimal efficiency as well as improve the look of your home.

Our 5-Step Professional Solar & Window Cleaning Process
Solar System Inspection: We inspect your solar panels and mounting hardware to ensure everything is functioning properly before cleaning begins. For windows we inspect the glass, screen, and seals. If there are any broken panels or other anomalies, we will take photos and alert you prior to starting the cleaning.
Purified Water Cleaning System: We use a deionized water filtration system that removes minerals and contaminants. This prevents streaks or residue from forming on your panels and windows. Our purified water cleaning system is designed to provide you with spotless and streak-free solar panels and windows. When it comes to maintaining the efficiency of your solar panels, cleanliness plays a crucial role. Even the smallest amount of dust, dirt, or grime can significantly reduce their ability to generate electricity. A streak free window keeps your home looking new and brightening up your space to let the sunlight in.
Soft Brush Debris Removal: Non-abrasive brushes (designed for Solar Panels) safely removes dirt, pollen, and bird droppings without damaging the panel surface. These brushes are attached to top-of-the-line water-fed poles. The reason it's important to use these style brushes is because soft agitation is crucial to remove all surface dirt & debris. Harder bristles (like shop brooms and scrubbers) will cause micro scratches, which will damage the delicate solar panel glass over time.
Spot-Free Rinsing: Purified water leaves panels spotless without chemical cleaners. Our process uses a two brush system to enhance both the outcome & efficiency of each cleaning. Once we've cleaned all of the dirt, debris, leaves, bird droppings, bee pollen, algae, mold, etc., off of the solar panel and windows with the first brush (we call it 'dirty brush') we go over the entire system with 'Clean Brush'. That final brush only ever uses Deionized filtered water, so the bristles stay extremely clean. This gives the final polish and leaving nothing on the glass but a mirror finish.
Final Quality Inspection: We pride ourselves on leaving your solar, windows, and surrounding area cleaner than we found it. Our technicians confirm panels and windows are fully cleaned, roof is clear of unsightly debris, check for broken tiles, ensure panels aren't cracked and no wires are damaged or misplaced. We perform one last walkthrough to verify that the work meets our rigorous standards of excellence. This final attention to detail guarantees you get a pristine result without having to lift a finger.
FAQs
Answers to Your Top Solar Cleaning Questions
Why do I need to clean my solar panels?
When dust, grime, and debris build up on your glass, dirty solar panels can lose 15% to 30% of their overall efficiency. This heavy layer of buildup physically blocks sunlight from reaching the solar cells, causing a direct drop in your daily power production. Scheduling regular professional cleanings instantly reverses this costly problem. We wash away the stubborn dirt to help you maintain optimal energy output and ensure your system operates at peak performance year-round.
Can I clean solar panels myself?
While you can technically clean your solar panels yourself, tackling this job without the proper equipment creates unnecessary risks for your system. Using common household chemicals, abrasive sponges, or hard tap water can easily scratch the delicate glass and leave behind mineral deposits that block sunlight. You also face serious physical dangers if you try to wash roof-mounted units without professional safety and training. Falls from a roof or ladder are among the top 3 most common home related causes of death. Professional Solar Cleaner's use methods and tools to mitigate the risks that you as a home owner wouldn't generally have access to.
Does rain clean solar panels?
While a heavy rainstorm might rinse away light surface dust, it simply isn't enough to keep your solar panels clean. Just like leaving your car out in a storm, rainwater cannot scrub away stubborn grime, dried bird droppings, tree sap, atmospheric oil sediment or hard water stains left behind after rain evaporation. To ensure your system absorbs maximum sunlight and operates at peak efficiency year-round, you need routine professional maintenance from GoldCoast to safely and thoroughly wash away this tough buildup.

How long will it take to clean all the windows in my house?
The cleaning time varies but generally completes within a few hours after initial assessment.
