Solar panel maintenance: Everything you need to know

Photovoltaic solar panels are designed to last a long time, typically 25 to 30 years, but they do require some maintenance to ensure they operate at peak efficiency. Over time, dust, debris, and weather conditions can impact the performance of the photovoltaic cells. Regular cleaning and maintenance can help maximize the lifespan and output of your solar panels.

But what exactly does "solar panel maintenance" involve? How often should you clean them, and is it something you can handle yourself? Or do you need to call in a professional? Additionally, are there any simple steps you can take to reduce maintenance costs? That’s what this article aims to address: how to keep your solar panels in top condition with minimal effort and expense. Keep reading to find out more.

Do solar panels really need maintenance?

Yes, solar panels do require some maintenance to ensure they continue to function optimally. Although regular rain showers can help keep the panels relatively clean, it's advisable to have them professionally cleaned every 12 to 24 months, depending on their location and exposure to environmental factors.

For added assurance, consider having a more comprehensive inspection and service done every 4 to 5 years. Our extended warranty, which is backed by insurance, can cover additional maintenance needs, ensuring your solar system operates smoothly for many years.

How frequently should you clean your solar panels?

While rain can help keep the panels free of light dust and debris, dirt and grime can accumulate over time, reducing their efficiency. It's generally recommended to have your panels professionally cleaned every 1-2 years. However, factors such as nearby trees, bird activity, and local air quality can influence how often cleaning is necessary. Regular inspections can help you determine when your panels need attention to maintain maximum energy production.

Proper installation and placement of solar panels

Another important consideration is avoiding placing solar panels in shaded areas or under trees where birds might perch. Not only does shade decrease the efficiency of the panels, but it could also attract birds to nest in nearby trees, which you want to avoid. These are basic considerations that any experienced solar installation engineer will keep in mind. During your survey, you can discuss any concerns about the installation with your Solar Together installer.

It's crucial to work with a professional to have your panels installed. Although solar panels don't have moving parts, there are several things that can go wrong:

• Improper roof anchoring can damage your roof tiles or result in panels being poorly secured.
• Panels must be connected to an inverter. Even though the panels themselves are pre-wired, they should still be installed by an MCS-certified professional. Issues can arise from improper grounding or exposed wiring.
• If the support legs are installed too close to the panel, it might create an angle that increases wind load stress.

Not only can poor installation lead to higher maintenance requirements, but it can also pose safety risks.

The high-quality panels and expert (MCS-accredited) installations offered by Solar Together can help you avoid these problems. Curious about whether you might need planning permission for your solar panel installation? Learn more here.

Installing bird deterrents for solar panels

One effective way to prevent birds from causing trouble for your solar panels is to install netting, 'bird barriers,' or bird deterrent kits. These terms refer to similar solutions. When your panels are installed, you can add mesh, netting, or wire strips that prevent birds from nesting beneath your solar panels. These barriers also help keep debris like twigs from accumulating around your panels. Bird protection is available through Solar Together at a fixed additional cost, and it's worth discussing with your installer during your on-site survey.

Cleaning solar panels on your roof

We strongly advise against attempting to clean your panels without proper training and equipment. For those with accessible panels, such as ground-mounted arrays, it's important to exercise caution when deciding how to clean them. Some cleaning products can cause damage, and using high-pressure washers can lead to water ingress.

Rather than trying to clean them yourself, we recommend contacting a professional cleaning service that can provide industry-standard guidance and services.

Can I hire a solar panel cleaner instead?

While some window cleaning companies may offer solar panel cleaning services, we suggest using a specialized solar cleaning company. They possess the expertise, tools, and training to properly care for your panels and ensure your warranty remains valid.

How does extreme weather affect solar panels?

Like all electronic devices, solar panels are impacted by extreme weather conditions.

• In cold weather, solar panels are unaffected. Snow covering the panel will temporarily halt energy production, but the panel's surface usually allows the snow to melt and slide off.
• In hot weather, panels generate less voltage and become less efficient.
• In stormy weather, solar panels are safe. They have a waterproof surface that keeps them clean and clear. They do not increase the likelihood of your home being struck by lightning.
• In windy weather, solar panels are secure. When installed correctly, they remain stable and safe even in strong winds.

This means that even if you live in an area prone to extreme weather, your panels shouldn’t require additional maintenance. Read our blog on whether your solar panels work in cloudy conditions.
