Defend your rooftop solar panels against vermin

If you have installed a rooftop solar panel system, it’s important to take steps to protect the panels from damage caused by pests such as squirrels and birds. In addition to causing physical damage, these animals can also cause a solar system to run less efficiently by disturbing the panels or covering them with droppings. Fortunately, there are several things you can do to protect your panels from vermin.

How to ensure your solar panels are free from vermin?

Rooftop solar panels are an increasingly popular way to save on energy costs, but they can also be attractive to vermin. Rodents and birds can damage rooftop solar panels in a number of ways, from chewing through wiring to simply nesting on top of the panels and blocking the sun.

One of the most common problems is damage caused by squirrels. These rodents have teeth that grow continuously, so they are always chewing and filing them down. This can lead to chewing through solar panel wiring, which can disable an entire system. Squirrels have also been known to urinate on solar panels, which can cause the metal to rust and reduce the amount of power they produce.

There are a few things you can do to keep pests away from the solar panels on your roof.

Keep your rooftop and solar panels clean

One way to ensure your rooftop solar panel stays in good condition is to keep it clean and free of debris. This provides vermin with hiding places and gives them easy access to the solar panels, which can damage them. In addition, rooftop solar panels can become covered in dust and dirt, which reduces their efficiency. Regular cleaning helps to remove this build-up and keeps the panels working at optimal levels. There are a few different ways to clean rooftop solar panels. One is to use a soft brush or cloth to gently remove any dirt or debris. Another is to use a pressure washer on a low setting, being careful not to damage the panels. No matter which method you choose, keeping your rooftop solar panel clean will help it last longer.

Trim back any trees or bushes near the rooftop

Another important thing you can do is to trim back any trees or bushes near the rooftop. These can provide vermin with a way to climb up to the panels, and they can also cause damage to the panels themselves. Also, you should check the panels often to make sure they don’t have any dirt or debris on them.

Installing bird netting

First, make sure that the panels are properly secured to the roof. This will help prevent animals from being able to knock them loose. Next, trim any trees or shrubs near the house, as these can provide a perch for birds. Finally, you can install bird netting over the solar panels to keep birds from landing on them. By taking these easy steps, you can help keep pests away from your solar panels on your roof.

Choosing the right type of net for your solar panels

To prevent rodents from damaging your solar panels, it is important to choose the right type of netting. The most common types of netting are made from steel or aluminum mesh. Steel mesh is the stronger of the two options, making it ideal for areas with high rodent activity. Aluminum mesh is lighter and more affordable, making it a good choice for smaller installations. Another option is to use polypropylene netting, which is made from plastic fibers. Polypropylene netting is strong and doesn’t get damaged by the weather, so it’s a great choice for keeping rodents away from your solar panels.

In conclusion, protecting your rooftop solar panels from vermin is essential to maintain their efficiency and longevity. By keeping your rooftop and panels clean, trimming back trees or bushes, and installing bird netting, you can minimize the risk of damage caused by pests such as squirrels and birds. Additionally, selecting the right type of netting, such as steel mesh, aluminum mesh, or polypropylene netting, can effectively deter rodents and ensure the safety of your solar panels. Taking these preventive measures will help you maximize the benefits of your solar panel system and protect your investment in renewable energy.
