Caring for Your Solar Panels: Essential Tips for Asset Longevity

Do Solar Panels Need Cleaning?

In most parts of the UK, rain is enough to keep solar panels clean. A sloped roof helps water run down and wash away dust and dirt. However, if you live near busy roads, trees, or farmland, you might face a different situation. You could find more dust, bird droppings, or even moss accumulating on your panels. This build-up can block sunlight and reduce the energy your system generates.

The Energy Saving Trust says that keeping panels clear is crucial for maximizing your solar setup. If you cannot safely see your roof, consider using binoculars or a drone. This way, you can check for signs of dirt or debris. If needed, hire a professional to clean them gently, using soft water and avoiding harsh tools.

What Else Can Go Wrong?

In addition to cleaning, it is essential to be aware of other potential issues. The most common problem in the UK is birds nesting under or around solar panels. This can lead to mess, blocked airflow, or even damaged wires. For help with this issue, we recommend reading our Bird Proofing Guide if you observe signs of bird activity.

Other rare issues can include:

• Broken glass due to flying debris

• Loose wiring resulting from age or poor installation

• Shading caused by growing trees or nearby buildings

  
  

By being vigilant, you can catch these problems early and prevent more serious damage.

How Often Should I Check My Panels?

It is a good idea to inspect your solar system a few times a year, particularly during the following times:

• In spring and autumn

• After strong winds or storms

• If your system’s energy output drops noticeably

  
  

Most systems come with online monitoring tools that let you track performance. If you notice that output is much lower than usual, it could indicate that something requires attention.

Additionally, consider booking a professional inspection every 2 to 5 years, especially for older systems or those that are out of warranty. Regular checks can prevent small issues from becoming significant problems.

Do I Need a Yearly Service?

You generally do not need a yearly service unless specified by your warranty or installer. However, a check every few years can offer several benefits:

• Spot small issues before they escalate into bigger problems

• Ensure your system remains safe and efficient

• Extend the life of your inverter and wiring

  
  

Some warranties may require proof of maintenance, so make sure to check your documents to stay compliant.

The Bottom Line: Keep Your System Healthy

Solar panels are one of the lowest-maintenance options available for reducing energy bills. With a quick check every now and then, you can keep your system functioning well for many years.

Always be on the lookout for signs of bird nests, dirt, or shading. If something seems off, do not hesitate to get it checked.
