Maintain Peak Efficiency with Hi-Connect Solar and Electrical
Installing a solar system is a fantastic way to reduce your energy bills and environmental impact. But to ensure your panels continue delivering optimal performance, regular cleaning is essential. Over time, dirt, dust, bird droppings, tree sap, and other debris can build up on the surface of your solar panels, significantly reducing their efficiency.
At Hi-Connect Solar and Electrical, we offer professional solar panel cleaning services to keep your system operating at its best—safely, efficiently, and affordably.
Why Clean Your Solar Panels?
Solar panels rely on direct sunlight to generate electricity. Anything that blocks sunlight—even a thin film of dust—can reduce their output. According to industry studies, dirty solar panels can lose 10% to 25% of their efficiency depending on the level of contamination and the local environment.
Cleaning your panels helps:
- Maximise electricity generation
- Reduce long-term maintenance costs
- Extend system lifespan
- Protect your investment
Solar panel cleaning is especially important if you live in areas with:
- High pollen levels
- Coastal salt spray
- Heavy bird activity
- Nearby trees or construction sites
- Agricultural zones with dust and fertilizer particles
How Often Should You Clean Solar Panels?
The ideal cleaning frequency depends on your location, roof angle, surrounding environment, and weather conditions. Here are general guidelines:
- Every 6 to 12 months: Standard recommendation for most residential systems.
- Every 3 to 6 months: For panels in dusty, coastal, or bird-prone areas.
- Post-storm inspection: After heavy winds or storms that deposit debris.
- Any noticeable drop in output: Clean panels if you observe a dip in your system’s performance or output reports
Hi Connect Solar and Electrical can help determine the best cleaning schedule for your property. We also offer routine maintenance plans that include periodic cleaning to make it hassle-free.
Our Cleaning Process
Cleaning solar panels may seem simple, but using the wrong tools or methods can damage your system or void warranties. That’s why it’s always best to leave it to professionals like Hi Connect Solar and Electrical.
Our process includes:
- Initial Inspection: We assess your system’s condition and surrounding environment to determine the type and extent of cleaning required.
- Gentle, Non-Abrasive Cleaning: We use purified water and soft-bristle brushes to clean the surface of your panels without scratching or damaging them. No harsh chemicals or detergents are used, as they can degrade panel coatings.
- Safety-First Approach: Our team is trained in working at heights and complies with all Australian safety standards. We use appropriate harnesses and safety equipment to ensure the job is done without risk to you or your property.
- Performance Check (Optional) As part of our service, we can perform a basic performance test post-cleaning to verify improved output.
- Before and After Report We provide visual documentation showing the condition of your panels before and after cleaning, so you can see the difference clearly.
Can You Clean Panels Yourself?
While it’s technically possible to clean panels yourself, we strongly advise against DIY cleaning for several reasons:
- Safety risks: Roof work involves fall hazards and electrical risks.
- Damage potential: Using high-pressure water, abrasive materials, or household cleaners can void warranties
When you choose Hi Connect Solar and Electrical, you get a safe, thorough clean with peace of mind.
