Reduced Energy Output

If you notice a sudden drop in your solar system’s energy production, it could be a sign that your panels need a clean. Dirt, dust, and other residues can build a film over your panels, blocking sunlight and reducing their efficiency. Monitoring your daily performance can help identify any significant changes that might indicate it’s time for a clean.

Visual Inspections

Take a moment to visually inspect your solar panels periodically. If they appear dirty or have visible accumulations of dust, pollen, or bird droppings, these can severely impact their ability to function effectively. We recommend visual checks especially after windy days when debris is more likely to accumulate.

It Has Been a While

Consistent cleaning schedule is key in maintaining your solar panel’s efficiency. If it’s been a while since your last clean, don’t wait for the signs. Dust and dirt can accumulate without you noticing, subtly decreasing the efficiency. As a rule of thumb, cleaning your solar panels at least twice a year is advisable, although this can vary depending on your location and environment.

After Bad Weather

If your area has experienced heavy storms, snow, or a long period of dry weather, your panels are more likely to need cleaning. Bad weather can leave stubborn grime that isn’t easily washed away by rain, and a professional clean-up might be the only solution to restore full efficiency.

Birds and Trees

If there are birds frequently perching near your solar panels, or if you live in an area surrounded by trees, it’s likely that your solar panels could become a prime target for droppings and falling leaves. These not only obscure the panel surface but can also cause long-term damage if not cleaned regularly.
