Solar Panels

Decreased energy production 

Dirt and debris (e.g., dust, bird droppings, leaves, pollen, and road grime) block sunlight from reaching the solar cells, directly reducing the amount of electricity generated. Studies have shown that performance can be reduced by 5-25% on average and, in extreme cases of neglect, the loss can be as high as 50% or more.

Financial impact 

Lower energy production means less savings on electricity bills, or less income if you are selling excess energy back to the grid (feed-in tariffs). Over time, this results in a poor return on your initial investment.

Physical damage and reduced lifespan 

Uneven shading caused by concentrated dirt can lead to "hot spots," where certain parts of the panel become significantly hotter than others. This localized overheating can damage solar cells, accelerate wear on internal wiring and components, and cause microcracks to form, ultimately shortening the overall lifespan of the panels.

Increased safety concerns 

Accumulated dirt can trap moisture, which may lead to corrosion of electrical contacts and other components, increasing the risk of electrical faults or even fire hazards.

Voided warranties 

Many manufacturers' warranties require regular cleaning and maintenance to remain valid. Failure to keep panels clean can void the warranty, leaving the owner responsible for costly repairs or replacements.

Aesthetic issues 

Clean panels look better and help maintain the property's overall visual appeal.

System imbalance 

In systems where panels are connected in a "string," one very dirty panel can lower the output of the entire row, as the output is limited by the least productive panel. 

Regular monitoring of your system's performance and occasional, safe cleaning by the professionals, LEGITIMO,  can help mitigate these issues and ensure that your solar panels operate at peak efficiency. 

LEGITIMO uses the same Water Fed Pole method to clean solar panels to ensure a longer lasting result. They can be cleaned regardless of whether they are sited on ground or up high like a rooftop.
