8 Telltale Signs Your Commercial Roof with Solar Panels Needs to Clean

When it comes to the maintenance of your commercial solar roof, most people tend to focus on things like regular inspections and repairs. However, one often overlooked aspect of keeping your solar panels in top condition is cleaning.

Regular cleaning of your commercial roof with solar panels is key to ensuring its optimal performance and longevity. In this article, we’ll discuss eight signs that indicate it’s time for a thorough cleaning of your commercial solar roof.

1. Visible Dirt and Debris

One of the clearest signs that your commercial solar roof needs immediate attention is the presence of visible dirt and debris. These things accumulate on the surface of the solar panels.

This buildup can range from common dust and leaves blown by the wind. It can also include more harmful things, like bird droppings and pollutants from the air.

Over time, these substances can build up a lot. They cover your panels and stop sunlight from reaching the solar cells.

Such buildup detracts from the look of your panels. More importantly, it reduces their efficiency blocking the sunlight they need for energy.

As a result, your solar energy system performs worse. So, it is crucial to fix this issue with regular cleaning.

2. Reduced Energy Output

A big drop in your solar panels’ energy output is a red flag. It shows they may need a thorough cleaning or inspection. As dust, dirt, and debris form a barrier between the sun and the solar cells, there is a marked reduction in energy production.

This scenario becomes problematic for operations that rely on solar power to mitigate energy costs. By closely tracking your energy output and comparing it over time, you can see when a decline may be due to dirt on the panels. This signals the need for maintenance.

3. Shaded Panels

Shading over part or all of your solar panels is another clear sign. It shows that your commercial solar roof needs cleaning. Or, the panels may need repositioning.

Shading can result from many obstructions. These include overhanging branches from trees, tall nearby buildings, or the accumulation of dirt and debris.

Partial or complete shading of your panels can result in efficiency loss or reductions. The obstructed sections cannot contribute to energy production.

Cleaning and positioning your solar panels often can greatly boost their performance. It lets them get the most sunlight each day.

4. Discoloration or Stains

The appearance of discoloration or stains on your solar panels often indicates algae or mold growth. These organisms find a particularly favorable environment on dirty solar panels. This is especially true in regions characterized by high humidity and moisture levels.

Algae and mold make your solar panels look bad. They can also cause permanent damage if not removed quickly.

Establishing regular cleaning routines can prevent the establishment and growth of these organisms. Thus, preserving the integrity and efficiency of your solar energy system.

Keeping panels clean enhances their appearance. It also ensures the longevity and reliability of your solar energy investment.

5. Bird Nests and Solar Panels

Birds often see solar panels as the perfect place to build their nests. This is because the panels are high up and stay warm all day.

Birds nesting under solar panels may seem harmless or charming at first. But, it poses a big risk to the panels’ function and durability.

Bird nests can lead to physical damage by corroding materials and obstructing sunlight from reaching the solar cells. Thus compromising the efficiency of your energy generation. In addition, bird droppings can be acidic and further damage the surface of the panels.

If birds are seen on your commercial solar rooftop, act fast. Schedule a professional cleaning, from OnPoint Solar Panel Cleaning, for example, to prevent damage and keep the panels working well.

6. The Impact of Snow or Ice

In regions experiencing colder climates, the accumulation of snow and ice on solar panels becomes a prevalent challenge during winter months. The majority of modern solar panels are engineered to tolerate such conditions without sustaining damage. The presence of heavy snow or thick layers of ice can obstruct sunlight and markedly reduce the efficiency of the panels.

This reduction in efficiency can have a significant impact on energy generation, especially during shorter daylight hours in winter. To maintain optimal performance, it’s advisable to engage in regular cleaning sessions to remove any snow or ice buildup. This ensures your solar panels continue to operate at their peak and provide consistent energy output.

7. Increased Energy Bills as a Warning Sign

A noticeable surge in energy bills can often serve as a clear indicator that your solar panels may require cleaning or maintenance. Layers of dirt, debris, and other obstructions such as fallen leaves can prevent sunlight from adequately reaching the solar cells. As a result, the panels must exert more effort to generate the same amount of energy, leading to an increase in energy costs.

This inefficiency can be particularly pronounced during periods of high energy demand. Addressing this issue promptly through thorough cleaning can restore the efficiency of your panels, help reduce your energy bills, and ensure that you are maximizing the return on your solar investment.

8. Adhering to Warranty Requirements

Many solar panel manufacturers outline specific warranty conditions that mandate regular cleaning and maintenance tasks to ensure the panels operate at their optimal performance level. Neglecting these requirements could potentially lead to the voiding of your warranty, leaving you unprotected in the event of a malfunction or damage that would otherwise be covered.

It’s imperative to familiarize yourself with the terms of your warranty and adhere to the recommended cleaning schedule. Regular maintenance not only ensures the longevity and efficiency of your solar panels but also helps preserve your warranty coverage, providing you with peace of mind and protection for your solar investment.

Don’t Ignore These Signs To Know If Your Commercial Roof with Solar Panels Needs Cleaning

Keeping a clean commercial roof with solar panels is vital for peak performance and making the most energy. Regular cleaning prevents dirt buildup, reducing energy output and damage. Address bird nests and snow buildup. Do so to meet warranty rules and protect your investment.

Clean panels enhance efficiency and support sustainability goals. Take proactive steps to clean for the best operation. They will secure your energy future and bring financial benefits.
