What Causes Solar Panel Damage?

Extreme weather conditions are among the most common causes of solar panel damage. Hail, hurricanes, and heavy snowfall can physically harm the panels. These severe conditions can result in damaged solar cells or cracked glass, which reduces the ability of the solar panel systems to generate electricity.

Another factor that can affect the performance and condition of solar panels is the accumulation of debris and dirt. Things like leaves, dust, bird droppings, and other airborne particles may settle on the surface of the panels over time. If not cleaned regularly, they can block sunlight, reduce the panels’ efficiency, and potentially cause long-term damage.

Temperature fluctuations, especially extreme and rapid ones, can also cause damage to solar panels. Although they can withstand various temperatures, constant expansion and contraction due to temperature changes can stress the materials, possibly leading to cracks or other damage.

The physical impact from fallen objects like tree branches or items carried by strong winds can cause significant damage. A strong enough impact can crack the glass surface of the panels or damage the underlying photovoltaic cells.

The age of the panels also plays a part in potential damage. As solar panels age, their efficiency gradually reduces, and they become more susceptible to wear and tear.

Furthermore, poor or incorrect installation can be a significant factor in causing damage. The panels may face mechanical damage or electrical issues if improperly installed and secured. Panels installed without considering optimal angles or direction can also affect efficiency.

Lastly, local wildlife, especially birds and rodents, can cause unexpected damage. They can dislodge wiring, build nests that block sunlight, or leave droppings that may damage the surface over time.

Why Solar Panel Cleaning is So Important

How Location Can Complicate Cleaning Frequency

Servicing practices can vary based on the location, such as the specific needs for solar panels in Dublin. Several factors, such as weather, pollution, and the installation angle, can influence the frequency of cleaning. Location plays a crucial role in determining these factors, and for a country like Ireland, it can indeed complicate the cleaning frequency. Here’s how:

Weather Conditions

The Atlantic Ocean significantly impacts Ireland’s climate, creating a mild and moist environment. Though rainfall can naturally clean the solar arrays somewhat, it can also leave behind mineral-heavy hard water spots on the panel surfaces. These spots can obstruct solar output by diminishing the sunlight reaching the cells. Consequently, panels may need cleaning more frequently to remove these spots and maintain optimal solar output.


Air pollution can be relatively high in urban areas or places close to industries. Dust, soot, and other pollutants can settle on the solar panels, reducing their effectiveness. Thus, if your solar panels are in these areas in Ireland, you should clean them more often.

Bird Droppings

Ireland is home to a diverse bird population. Bird droppings on solar panels are not uncommon and can significantly reduce their efficiency, as they are more opaque and sticky than dust or dirt. The need for cleaning would be more frequent in locations with high bird populations.

Shading and Angle of Panels

If panel installation is at a low angle, they may not self-clean as effectively in the rain. Additionally, locations with many surrounding trees may experience more shading, leading to moss or algae growth on the panels. In such cases, cleaning would need to be more regular.

Seaside Locations

For solar installations near the coast, the high salt content in the sea breeze can cause salt deposits on the solar panels. These deposits can decrease the panels’ performance and increase the need for regular cleaning.

Seasonal Factors

During some seasons, such as spring, pollen might increase, which can accumulate on the PV solar panels. It would mean a higher cleaning frequency during certain times of the year.
