How often should I clean my solar panels?

Fast read

To keep solar panels operating at their peak effectiveness and efficiency, it is advised to clean them regularly. Unfortunately, rain rarely entirely cleans panels; some stains require specific cleaning methods or removing substances.

On a sunny day, cleaning solar panels can be dangerous because electric shock is possible. Some solar panel warranties require regular solar panel maintenance, where professionals can look at and repair minor problems before they become worse.

The frequency of solar module cleaning depends on their position and state. However, a good general guideline is to clean them every two to three years.

Should I get my solar panels cleaned regularly?

Ensuring your solar panels stay clean is crucial for their efficiency and longevity. Over time, panels gather dust and debris, which can block them and prevent them from working well. Picture this: it’s akin to having a layer of grime on a window—it prevents light from passing through clearly.

Similarly, when your solar panels are dirty, they struggle to absorb sunlight effectively. Professional cleaning steps in as the solution, clearing away these obstructions to allow the panels to capture maximum sunlight. It’s like giving your panels a refreshing shower to ensure your system’s performance is at its peak.

Your home’s energy production will become more efficient. This allows you to maximise your solar investment now and in the future.

Rain does not always clean properly

Homeowners think and solar salespeople say that rain cleans solar panels with a quick shower. But, unfortunately, the surface of a solar panel requires more than a shower to remove bird or bat poo, the sap of nearby flowering trees, and built-up dust. Flat roof panels, such as pergolas or large-scale commercial systems, are often installed at an angle of less than 10 degrees. This is particularly true for these types of roofs.

Therefore the common assumption that rain cleans solar panels for you is false. Rain can actually make solar panels dirtier because rainwater often contains dust, minerals, and chemicals. Instead of cleaning the panels, the rain leaves behind a layer of debris.

Some customers opt for a DIY cleaning approach to save some money. Unfortunately, it is not that simple, as working on roofs can challenge a Do It Yourself handyman. Also, it’s not worth going to the hospital after a fall just to save a little money on cleaning solar panels.

Know how to remove any stains on panels

To effectively remove stains from solar panels, you need to know what type of stain is on the glass. A skilled cleaner can recognise different stains and flaws that can affect how well solar panels work.

Different stains require different cleaning approaches. Bird poop or tree sap may need soaking or special cleaning products made for removing organic waste. These substances can create stubborn marks on the panels, impacting their efficiency.

To remove mineral deposits or hard water stains, use gentle abrasives or mild acidic solutions. These deposits, if left unattended, can reduce the panels’ ability to capture sunlight effectively.

Cleaning solar panels can be dangerous

Ensuring the safety of your solar panel maintenance is paramount, making professional cleaning services the preferred choice. Roof-mounted solar panels pose unique challenges, and attempting to clean them independently can be risky.

Using a ladder to reach your roof may seem easy, but it can be dangerous. This is especially true if your roof is small, steep, or on the second floor. In such scenarios, the potential risks associated with climbing ladders outweigh the perceived cost savings.

Professional cleaners, armed with experience and expertise, are equipped to handle these challenges safely. They have the right tools and methods to clean roofs safely and effectively, even in difficult configurations.

Moreover, the expertise of a seasoned professional goes beyond just using tools. They are trained to find and fix safety problems while cleaning, making sure the job is done safely.

While the temptation to save a few dollars by taking a DIY approach may be present, investing in professional solar panel cleaning not only safeguards your well-being but also ensures that your solar energy system continues to operate at peak efficiency. Choosing safe and experienced professionals gives peace of mind and an easy solution for keeping your solar panels in good condition.

Dangerous if washed on a sunny day

To keep your solar power system working well, it’s important to do regular maintenance. While you might want to clean the solar panels yourself, it’s important to know the risks involved.

Turning off the safety switch for your solar power system does not remove all electrical dangers from solar panels. Unlike some other electrical products, solar panels can still retain a DC electrical charge even when the safety switch is turned off. This is a critical factor to consider, especially for routine tasks like cleaning.

The process poses various risks, including working at heights, exposure to water, and dealing with electricity. Even wiping wet panels can be dangerous because of the leftover electrical charge.

It’s safest to hire a professional to help with navigating dangers and protecting both people and the solar power system. A professional can ensure safety and security for both individuals and the solar power system. Their expertise can help prevent accidents and keep everything running smoothly. By hiring a professional, you can have peace of mind knowing that you are in good hands.

Some solar workmanship warranties do not want a handyperson near them

Warranty specifications can be another important reason for cleaning your panels professionally. Solar companies and solar panel manufacturers now require regular cleaning and maintenance as part of their warranty terms. If you encounter an issue with your panels within the warranty period but have not cleaned and looked at your panels for many years, you may not be able to make a warranty claim for the issue.

Having your solar system checked by a professional every 2 to 3 years is a good idea. This helps with maintenance and ensures its proper functioning.

This helps individuals identify minor issues early on. For example, they may discover a loose panel clamp. By doing so, they can prevent these problems from escalating into major concerns. Ultimately, this proactive approach safeguards the well-being of those they value.
