Are Solar Panels Waterproof?

Solar panels are generally installed on the roofs of independent homes, residential complexes, and commercial buildings. These panels have revolutionized the use the green energy in urban settings.

Over the years, developers have come up with even more creative uses of solar power. Panels can be seen powering everything from study lamps to cars. However, this versatility is only possible if solar panels can withstand different types of weather conditions.

The concern around their ability to tolerate different weather conditions is completely understandable. Moreover, one of the most frequently asked questions about solar panels is if they are waterproof.

Continue reading to find out if the solar panels you are planning to install in your home or office are fit for damp conditions!

Key Takeaways

• Most solar panels are waterproof and designed to withstand various weather conditions, including rain.
• Solar panels are protected from water damage by top layers of waterproof glass, durable polymer-based materials on the bottom surface, and metal frames on the sides.
• While solar panels are generally sturdy, they can be damaged by falling debris, low maintenance, and frequent hailstorms. To protect them, consider insurance, proper installation, regular maintenance, and preventative measures like trimming trees and cleaning panels.

Are Your Solar Panels Waterproof?

Yes, most solar panels are waterproof. Once installed, solar panels are meant to last for years, if not decades. And since they are generally installed on rooftops, they will need to withstand weather conditions like rain. It is not feasible for you to manually protect them from water damage every time it starts to pour.

As you may already know, solar panels take up the sun’s energy or solar energy and convert it to electrical energy for our personal use. At the same time, the solar cells on the surface capture the energy, the conversion take place inside solar panels. Naturally, the panels contain electrical wiring to transport this energy along with other electrical fixtures.

Solar panels must be water-resistant, not just for the solar cells on the surface but for the electrical wiring within. Your solar panels are completely waterproof and can withstand most weather occurrences like rain. Right from the surface of the panels to the electrical fixtures that are within, everything is built keeping water exposure in mind.

What Protects Solar Panels From Water Damage?

Solar panels are protected from water damage from both the sides, the top, and the bottom. The top surface of the solar panels is covered with a protecting sheet. This top layer is waterproof and is made of a thin glass material. It is completely transparent so that the solar cells on the surface can absorb the sun’s rays efficiently.

The bottom surface of the panels is also covered with a protecting layer. However, this layer is not made up of glass. It is a durable sheet made up of various polymer-based materials. Metal frames additionally protect the solar panels from the sides, which are held in place by sealant glue. All this helps protect the solar panels from water damage, making them completely waterproof.

In rare cases, extreme external exposure could end up damaging the solar panels. However, most companies provide their customers with good warranties against such damage. So, it is unlikely that your solar panels will endure any substantial water damage, and even if they do, you can contact customer service for further assistance.

Can My Solar Panels Handle Other Weather Conditions?

Solar panels are not area or geography-specific and can be installed anywhere. As long as you get sunlight during the day, you can install solar panels to harness solar energy. Moreover, you have nothing to worry about even if you experience extreme weather conditions where you live.

Solar panels are built in such a way that they can withstand rain, snowfall, and even infrequent hailstorms. If you experience hailstorms once in a while, you might be concerned about the damage they can cause to your panels. However, the protecting glass on the surface of the solar panels is strong enough even to endure hailstones at times.

Additionally, if you experience strong winds in your area, you might want to contact your installation service and brief them about the high wind velocities experienced. You might have to use a special racking system to ensure that your solar panels are held in place.

This racking system is nothing but positioning your solar panels in such a way that the wind does not carry them away. Moreover, you will have nothing to worry about with proper installation as solar panels do not move once they are fixed in place properly.

What Can Damage Solar Panels?

While solar panels are generally very sturdy, a few things can certainly cause damage to them. Watch out for the following if you want to prolong your solar panel’s lifespan!

Falling Debris

One of the major causes of damage to solar panels is falling debris. This could be small branches from the trees nearby. While solar panels have a sturdy build, heavy impacts like tree branches can damage them. If you live near a construction site, debris and dust from these sites can cause damage to your panels too.

Low Maintenance

The glue that holds the metal frames of solar panels together can weaken over time. This is especially true when you experience heavy and frequent rainfall in your regions. You must change this glue and do frequent maintenance checks to prevent future water damage to your solar panels.

Frequent Hailstorms

The protective layer on the surface of solar panels can withstand mild hailstones once in a while. However, if hailstorms are a frequent phenomenon where you live, this might be a problem for your panels. While there is not much you can do to prevent damage caused by hailstones, you can always install smaller-sized panels to reduce the damage!

How To Protect Solar Panels From Environmental Damage?

If you want to make your solar panels last for years and work as efficiently as ever, you might want to start looking after them. Solar panels are made to endure environmental damage caused by extreme weather conditions. However, sometimes it is better to take precautionary steps for additional care.

Here are a few things you can do to prevent environmental damage.

Get an Insurance

If your solar panels are not included in your home insurance, you must get them insured against theft, damage, and other mishaps or malfunctions.

Make Sure the Installation Is Good

Ensure your solar panels are installed correctly right from the get-go by experienced solar energy installers; this will reduce the chances of any physical damage that weather conditions can cause.

Frequent Maintenance

Check the fixtures from time to time, along with their external conditions. If you feel like they could use an upgrade, contact your solar panel’s provider, and get adequate maintenance done.

Trim the Trees Around Your Roof

Trim the trees near your solar panels so that they do not fall and damage their surface.

Try to reduce the number of birds around the panels

If you have predatory or large birds around where you live, you should try to fence your panels so that they do not cause any physical damage.

Clean the Panels Regularly

Dirty panels can result in reduced efficiency and eventually malfunction. For instance, if you recently experienced a dusty storm, you might want to clean the surface of your panel so that it can absorb sunlight more effectively.

Note Down Your Panel’s Serial Number

If you are concerned about theft, mark your solar panel, or note its serial number. This way, you will know if someone steals your panels and tries to resell them!

Case Study: Ensuring Solar Panel Durability Through Effective Installation and Maintenance
