What Issues Are Addressed With Solar Panel Maintenance?

Your solar power system is designed for continuous operation year after year, but environmental factors will eventually take their toll. Occasional cleaning is necessary to improve performance and stop corrosion and damage resulting from:

  • Dirt and Debris – Accumulating dirt, dust, leaves, bird droppings, and other debris can reduce the efficiency of solar panels. Over time, this buildup can create shadows, block sunlight, and corrode the solar cells.
  • Pollution and Airborne Particles – Airborne pollutants like industrial emissions or particulate matter can settle on solar panels. This pollution can create a film on the surface, impacting the amount of sunlight reaching the photovoltaic cells and reducing energy production.
  • Birds and Animals – Birds, nesting materials, and other animals can cause physical damage to solar panels. Periodic solar panel maintenance will look for signs of animal activity and take steps to dissuade them from frequenting your roof.
  • Weather and Environmental Factors – Harsh weather conditions, including hail, rain, or extreme temperatures, can cause physical damage to solar panels over time. Hailstones, in particular, can create dents or cracks on the surface and require solar panel repair or replacement to keep your system operating efficiently.

Periodic inspections are essential to maximize the efficiency and lifespan of solar panels and identify any signs of wear or damage. Cleaning can involve a gentle approach using water and a soft brush or more specialized methods, depending on the severity of the dirt or debris accumulation. Regularly scheduled solar maintenance service helps ensure optimal performance and a longer operational life for solar panels.

Critter Guards

Animals like birds and rodents that nest or feed in and around solar panels could damage them and reduce their performance. Our professional solar maintenance services can remediate the threat to your investment by installing Critter Guards to keep pests away. Birds and rodents can find the space beneath solar panels attractive for nesting, leading to various issues. Nesting materials and debris can accumulate, creating a fire hazard, hindering proper ventilation, and potentially causing damage to the solar panel components. Birds and rodents also leave droppings on the panels, leading to corrosion over time.

Critter Guards are a preventive measure to deter animals from accessing the space beneath solar panels. These guards are typically mesh or wire barriers designed to fit securely around the perimeter of the panels, creating a barrier that prevents birds and rodents from getting underneath. Installing critter guards requires professional expertise to ensure a secure and effective fit without compromising the structural integrity of the solar panel system.

Our technicians will assess the need to incorporate critter guards as part of your solar maintenance services. Sometimes, cutting back overhanging trees and vegetation may greatly dissuade birds and other pests from frequenting your solar paneling. Turn to our experienced maintenance services to deliver solutions that safeguard your investment and contribute to the sustainable and uninterrupted generation of clean energy from your solar panels.

How Often Should I Have My Solar Panels Cleaned?

Many solar panel manufacturers suggest cleaning at least twice a year. However, more frequent cleaning may be beneficial in areas with specific environmental challenges. Some homeowners choose to clean their solar panels every 3 to 6 months, while others may do so annually.

The frequency of cleaning for solar panels depends on various factors, including the local climate, the environment, and the specific conditions at the installation site. Here are some general guidelines for determining how often you should consider cleaning your solar panels:

  • Location – Frequent cleaning may be necessary in areas with more dust, pollen, or airborne particles. Similarly, locations near construction sites or industrial areas may require more regular cleaning due to higher levels of pollutants.
  • Rainfall – Regions with regular rainfall may experience natural cleaning, as rain can help wash away some dirt and debris. However, rain can also contain pollutants and minerals and leave behind residue after it falls, making it necessary to clean after seasons with frequent showers. 
  • Tilt Angle and Orientation – Solar panels with a flat tilt or less favorable orientation to facilitate natural cleaning from rain will accumulate dirt and debris faster.
  • Seasonal Changes – Consider seasonal variations when determining the best time to schedule professional solar panel cleaning services. For example, during the fall, leaves may accumulate on the panels, and in winter, snow may cover them. Cleaning after such events can optimize solar panel performance.
  • Efficiency Loss – Monitor the efficiency of your solar panels. If you notice a significant drop in energy production, it may be a signal that cleaning is needed.

Professional inspections during regularly scheduled solar panel maintenance will determine if more frequent cleaning is necessary. An experienced technician may also uncover inefficiencies in your solar system due to debris accumulation that you hadn’t noticed, potentially optimizing performance.

How Are Solar Panels Professionally Cleaned?

When cleaning solar panels, following manufacturer guidelines and using gentle methods to avoid damaging the panels or their coatings is crucial. The job is best left to professionals as part of your routine solar panel maintenance. Some considerations are the type of solar panels, how they are installed, and environmental conditions in your area. Proper cleaning will contribute to your solar panel system’s longevity and performance.

Professionals use several methods to clean solar panels, ensuring optimal performance and efficiency. Here are common approaches employed during professional solar panel cleaning:
