Call UsWhy Solar Panel Cleaning Matters
Sydney’s mix of coastal air, pollen, and urban dust means solar panels don’t stay spotless for long. Over time, grime, bird droppings, and pollution create a thin layer on the glass that blocks sunlight, directly reducing your system’s efficiency and your power savings.
Professional solar panel cleaning in Sydney helps maintain your system’s performance and protect your investment.
The Hidden Cost of Dirty Panels
Even a small buildup of dirt can lead to a 5–20% drop in energy output. That’s power you’re paying for but not using. For households and businesses relying on solar to offset energy costs, this can mean hundreds of dollars lost every year.
Regular cleaning ensures your system is operating at peak efficiency, helping you get the best possible return on your solar investment.
Why You Shouldn’t DIY Solar Cleaning
Climbing on your roof with a hose or pressure washer might seem simple, but it’s not worth the risk.
-
Safety first: Roof surfaces can be slippery, and improper equipment can cause falls or injuries.
-
Avoid damage: Using harsh water pressure or chemicals can scratch or degrade your panels.
-
Warranty protection: Some manufacturers require professional cleaning to maintain your system warranty.
A certified solar technician has the right tools and experience to safely clean your panels while inspecting for potential issues like cracked glass, loose wiring, or shading problems.
How Often Should You Clean Your Panels?
In Sydney’s climate, every 6–12 months is ideal. If you live near the coast, on a busy road, or under trees, more frequent cleaning may be needed to keep performance high.

FAQs about Solar Panel Cleaning in Sydney
Everything Sydney Homeowners Ask Us About Solar Panel Cleaning in Sydney.
How often should you clean solar panels in Sydney?
Most Sydney homes benefit from professional solar panel cleaning every 6 to 12 months. If you live near the coast, under trees, or in a high-traffic area, you may need to clean more frequently to prevent salt, sap, and dust from affecting performance.
Does cleaning solar panels really make a difference?
Yes, regular cleaning can improve solar efficiency by up to 20%. Dirt, grime, and bird droppings block sunlight, reducing your system’s power output and increasing payback time. A professional solar panel clean restores full energy production and protects your investment.
Can I clean my solar panels myself?
It’s not recommended. DIY cleaning can be dangerous and may void your warranty. Professional solar panel cleaners use non-abrasive equipment and purified water to safely remove buildup without damaging glass or seals.
What happens if you never clean your solar panels?
Neglecting cleaning leads to reduced efficiency, long-term degradation, and potential warranty issues. Over time, accumulated dirt can cause uneven shading, hotspots, and premature wear, costing you both performance and money.
Is solar panel cleaning covered under maintenance or warranty?
Most warranties require panels to be kept clean but don’t include the cleaning itself. However, professional solar panel cleaning helps maintain compliance and protects your manufacturer’s performance guarantees.

MPV Solar’s cleaning service includes:
-
Gentle, chemical-free washing of all panels
