If you're an RV owner who enjoys the benefits of solar power, you might be wondering how to protect your solar panels from hail. Hail can pose a significant threat to your RV solar system, especially if you live or travel in areas prone to hailstorms. Hail can damage the glass surface of your solar panels, reduce their efficiency, and even cause them to stop working altogether. 

In this blog post, we'll explore just how delicate RV solar panels are, the types of damage hail can cause, and provide 7 easy and effective ways to protect your solar panels against hail damage. We'll also offer advice on selecting the best hail-resistant solar panels and more.

Let’s dive into it!

Hail Can Damage the Solar Panels

RV solar panels can withstand most hailstorms. However, if the hail is large enough to dent your vehicle, it can potentially damage your solar panels as well.

The most vulnerable part of a solar panel is the glass cover that protects the photovoltaic cells underneath. This glass cover is usually made of tempered glass, which is stronger and more resistant to impact than regular glass. However, even tempered glass can crack or shatter if hit by large or fast-moving hailstones.

Some common types of hail damage include:

  • Cracks: Small cracks in the glass surface may not significantly affect performance, but they can reduce aesthetic appeal and make the solar panels more prone to further damage.

  • Shatters: Large or severe cracks in the glass surface of your solar panels can cause them to shatter completely, exposing the photovoltaic cells underneath. This can result in a significant loss of power output and even create fire hazards.

  • Dents: Hailstones can also dent the metal frames or mounting brackets of your solar panels.

  • Disconnections: Hailstones can knock off or loosen the wiring or connectors of your solar panels, causing them to disconnect from each other or the battery bank. These disconnections can interrupt the electricity flow from your solar panels, preventing you from getting enough power.

7 Easy and Effective Ways to Protect Your RV Solar Panels From  Hail

Fortunately, there are some simple and effective ways to protect your RV solar panels from hail damage. Here are 7 of them:

1. Buy Resilient and Waterproof Solar Panels

One of the best ways to protect your RV solar panels from hail is to invest in resilient and waterproof solar panels. For example, BougeRV’s flexible solar panels, which utilize thin-film solar cell technology, are designed to be hail-resistant for use on an RV.

Most solar panels manufactured today are generally tough. Solar panels rated UL 61730 can withstand strikes of hail between 1 and 3 inches, moving at speeds up to 88.3 miles per hour (142 kph). So when shopping for RV solar panels, look for those that meet this standard because they can survive most hailstorms.

If you prefer rigid solar panels, consider investing in waterproof and dustproof ones with an IP67 waterproof rating. Cracks in solar panels caused by hail can lead to leaks, which can result in further damage to the solar panels. IP67-rated solar panels can continue to function and produce power even when submerged underwater.

Most solar panels meet the above standards and are waterproof, so it’s less likely that your solar panels will be severely damaged by a hailstorm. 

However, states such as California, Texas, Oklahoma, and Nebraska often experience heavy and dangerous hailstorms that can damage rigid solar panels. So, in these areas, it may be wise to invest in flexible solar panels. Here’s a YouTube video demonstrating how tough and resilient a flexible RV solar panel can be!

2. Install Solar Panels Properly

Install your solar panels properly and securely on your RV roof to prevent them from moving or falling off during a hailstorm and reduce the risk of damage.

If possible, consider an adjustable mounting system that allows you to angle the panels away from the storm's path. By minimizing the force and surface area exposed to the falling hail, you'll help protect your solar panels from damage.

3. Use a Solar Panel Protection Cover

When you expect a hailstorm or when you park your RV for an extended period, consider placing a protective cover over your solar panels to prevent damage.

A solar panel protection cover can shield your solar panels from hail, dust, dirt, bird droppings, and other debris that can harm them or reduce their efficiency. There are different types of solar panel protection covers available, such as:

A. RV Solar Panel Protective Cover

Hardcovers offer the best protection against impacts. They completely shield your solar panels, absorbing the full force of hailstones while preserving the panels underneath. However, the hardcovers block light, so your solar panels can't generate power while covered. It’s essential to remove the hard case after the storm passes.

Softer covers provide less protection, mitigating both sound and impact against the glass. While not as effective as hardcovers, they are easier to handle. In most hailstorms, a soft cover can be enough to protect your solar panels.

B. Hail Cover

A hail cover can be effective in protecting your solar panels from small to medium-sized hailstones but may not withstand large or severe hailstorms. Often made of thick, padded material, a hail cover can absorb the impact of hailstones and prevent them from cracking or shattering your solar panels.

However, hail covers can reduce the amount of sunlight reaching your solar panels, thus reducing power output. Therefore, you should only use hail covers when necessary and remove them as soon as possible after the hailstorm has passed.

C. Tarp

Using a tarp is a straightforward and inexpensive way to cover your solar panels quickly. A plastic or canvas tarp can offer some level of protection from hail.

D. RV Covers

RV covers can offer a degree of protection against hail. They can cushion the impact of hailstones on solar panels and various parts of your RV, such as the roof, windows, doors, vents, and skylights. 

However, RV covers may not be the best solution for stopping large or fast-moving hailstones from denting or piercing through your RV's roof or walls. Additionally, RV covers may tear or rip if hit by sharp or jagged hailstones.

4. Spray on a Methacrylate Layer

Applying a methacrylate layer can create a hard, transparent, protective film that helps prevent hail from cracking or shattering the glass.

Methacrylate is inexpensive, easy to apply, and long-lasting, and it does not affect the performance of the solar panels. However, applying too much methacrylate can reduce the solar panel output. And don’t spray methacrylate on the metal parts of the solar panel to avoid potential damage and reduced electrical conductivity.

5. Protect the Solar Panels with Wire Mesh

For an affordable and simple solution, you can cover your RV solar panels with wire mesh to protect them from hail.

The advantages of using wire mesh include its low cost, ease of installation, and removability. However, it can reduce the amount of sunlight reaching the solar panels, may rust or corrode over time, and can create noise when hail strikes it.

6. Maintain and Inspect Your Solar Panels Regularly

Regular checks ensure that your solar panels are functioning properly, free of dirt and debris, and without cracks or damage. Spotting potential issues early allows you to address them before they worsen. By maintaining and inspecting your solar panels regularly, you can extend their lifespan, improve efficiency, and avoid costly repairs or replacements.

Here are some steps for maintenance and inspection:

  • Clean your solar panels at least once a month or more frequently if exposed to dust, pollen, or bird droppings.

  • Inspect your panels for any cracks, chips, dents, or scratches. Minor damages can be filled in with epoxy or silicone sealant. For major damages, consider solar panel replacement or professional repair.

  • Check your wiring and connections for loose or broken parts that might cause short circuits or fire hazards. Tighten or replace as needed, and insulate any exposed wires with electrical tape or heat shrink tubing.

  • Examine your batteries and charge controller for signs of wear or malfunction. Consult your manual or contact the manufacturer for troubleshooting or replacement if you encounter problems.

7. Check the Weather Forecast 

Another effective strategy to protect your RV solar panels from hail is to check the weather forecast before traveling. This way, you can steer clear of areas likely to experience hailstorms or plan for alternative routes or shelter.
