Your solar panels work hard every day, soaking up sunlight and converting it into energy to power your home. But over time, they accumulate dirt, dust, bird droppings, and other debris that can compromise their efficiency. Cleaning solar panels is a key step in solar panel maintenance, ensuring they perform at their maximum capacity.
But when is the best time to clean solar panels for optimal results? This guide will walk you through everything you need to know, from the ideal time to clean them, to environmental factors to consider, and how to clean your solar panels safely.
Why Keeping Solar Panels Clean is Essential
When dirt or debris settles on your solar panels, it creates a thin layer that can block sunlight from reaching the photovoltaic cells. This disruption impacts the system’s ability to generate power. Studies have shown that dirty panels can lose as much as 20–25% of their efficiency, resulting in higher electricity bills and wasted potential of your system.
Keeping your panels clean ensures:
- Maximum energy output for your home or business.
- Lower costs associated with reduced reliance on grid power.
- Extended panel lifespan, protecting your investment.
Factors that Affect Solar Panel Cleaning Needs
The timing and frequency of cleaning your solar panels depend on several factors:
Seasonal Weather
Seasonal changes directly affect the cleanliness of your solar panels. For example:
- Spring: Pollens, seeds, and blooming flowers can leave panels coated with a yellowish residue. Rain often helps wash them off, but not entirely.
- Summer: Dust storms and hot, dry weather lead to more dirt settling on the panels, reducing energy efficiency.
- Autumn: Falling leaves and airborne debris can smother panels, particularly if your property is surrounded by trees.
- Winter: Panels can accumulate snow in colder climates, or streaks of grime due to erratic rain patterns in temperate regions.
Local Pollution
If you live near industrial zones, highways, or urban areas with high levels of air pollution, your panels may collect more soot and fine particles, needing washing more frequently.
Position and Angle of Panels
While angled solar panels allow rainwater to wash away most debris, flat panels tend to trap dirt and water, leading to streaks. Similarly, panels installed near chimneys, trees, or construction zones may require extra attention.
Wildlife
Bird droppings are one of the most stubborn pollutants, and they don’t simply wash away with the rain. Regular inspections are key in such areas to ensure optimal energy production. Bird proofing is another service we offer to help with this issue.
The Best Time to Clean Solar Panels
To achieve maximum energy output, it’s important to align your cleaning routine with seasonal conditions. Here’s when to clean solar panels:
Autumn and Early Spring
These periods are often the best times to clean your panels. With moderate weather and less harsh sunlight, it becomes easier and safer to clean panels manually if required. Early spring cleaning is particularly useful to address grime accumulated during winter.
After Long Dry Spells
If you’ve experienced a dusty summer or an extended dry period, plan on washing solar panels right after conditions normalise. Dust build-up can significantly affect energy production during such periods.
Following Major Environmental Events
Bushfires, heavy storms, or pollen-heavy seasons are events that likely leave a significant layer of debris on your panels. Cleaning them soon after such events ensures they’re back to peak performance.
By prioritising these times, you can ensure your panels are clean when it matters most, preventing long-term dirt accumulation.
Guide to Keeping Your Solar Panels Clean
Cleaning solar panels is complicated, and it must be done carefully to avoid damage. We will always recommend hiring a professional solar panel cleaning service, like myself, Johnny On The Spout, however here are some tips to keeping your Solar Panels clean in the interim.
1.Check for Debris and Damage on the roof
- Inspect your roof for loose debris, cracks, or damaged wiring. Address any major issues before proceeding with cleaning, if your roof has debris, your solar panels probably will too. If you see any damaged at all make sure to call Johnny On The Spout, or your solar panel provider.
2.Remove major bits of debris from the roof
- safely remove large bits of debris from the roof so that the professionals can come in an inspect the solar panels, and then if safe I can come in and do a major clean for you.
3.Call Johnny On The Spout
- Although you might want to clean the solar panels yourself, it’s much too dangerous and risky. Solar panels can easily be damaged and you can cause further harm instead of doing good. Call today on 0487 887 172, and I’ll be happy to organise a time with you.
4.Check Energy Output
- Once your panels are back in operation, monitor their energy output to ensure they’re performing optimally.
5.Keep My Number
- I’m always happy to help!
If your panels are on a roof, increase your safety by using a sturdy ladder, harness, and appropriate footwear. Hiring professionals for roof-mounted solar panels is always the safest option.
Benefits of Regular Solar Panel Cleaning
Regular cleaning offers a range of advantages for both the efficiency of your system and your wallet:
- Enhanced Efficiency: Clean panels generate more electricity, maximising your investment.
- Cost Savings: Reduced dependency on grid power means lower energy bills.
- Environmental Impact: By maintaining clean panels, you contribute to a more sustainable energy solution.
- Extended System Life: Well-maintained panels are less prone to damage and require fewer costly repairs over time.
