Call UsDo Clean Solar Panels Really Work Better?
If you’ve had solar panels for a while, you might be wondering, does cleaning them actually make a difference? The short answer is yes.
Regular cleaning can have a noticeable impact on your solar system’s output and efficiency, especially in Sydney’s dusty, coastal, and high-pollen conditions.
How Dirt and Dust Affect Solar Performance
Over time, solar panels accumulate dust, bird droppings, salt, and pollution. These layers block sunlight from reaching the cells, reducing the panel’s ability to generate power efficiently.
Studies and field tests show that dirty panels can lose up to 20% of their output, and in some cases even more after extended dry spells.
Before and After Cleaning: Real-World Results
Homeowners who have their panels professionally cleaned often report immediate increases in energy production, sometimes by 10–25%.
Clean panels also ensure your inverter operates efficiently, avoiding potential long-term faults caused by irregular performance or overheating.
Additional Benefits of Cleaning Solar Panels
✅ Maximised Efficiency: Clean panels absorb more sunlight, improving your return on investment.
✅ Extended Lifespan: Removing corrosive residues (like salt and bird droppings) prevents damage.
✅ Better Monitoring Accuracy: Cleaner panels provide consistent readings for your solar monitoring app.
✅ Improved Curb Appeal: Shiny panels look better on your roof and reflect proper maintenance.
How Often Should You Clean Your Solar Panels?
For most Sydney homes, a professional clean every 6–12 months is ideal. However, homes near the coast, main roads, or under trees may need more frequent cleans.Pairing cleaning with an annual inspection ensures your system stays in top condition year-round.
DIY vs Professional Solar Panel Cleaning
While some homeowners try DIY cleaning, professional cleaning is safer and more effective. Trained technicians use pure water systems, soft brushes, and the right safety gear, avoiding damage to panels or wiring while achieving streak-free results.
