Understanding the Threat of Hail Damage
As a seasoned roofing professional, I’ve seen firsthand the devastation that severe weather events can have on solar panel installations. While modern solar panels are incredibly durable, able to withstand all kinds of harsh outdoor conditions, hailstorms and high winds pose a genuine threat that homeowners and business owners must take seriously.
Hail, in particular, can wreak havoc on rooftop solar arrays. Hailstones form when moisture is rapidly pushed upwards during thunderstorms, creating solid ice projectiles that can travel at incredibly fast speeds – up to 75 mph in some cases. When these frozen missiles collide with the tempered glass surface of solar panels, they can cause cracking, chipping, and even complete breakage.
Even if the external damage appears minimal after a hailstorm, the internal solar cells and components may suffer harm from the impact. This can lead to a decrease in the panel’s energy production, efficiency, and overall lifespan. Over time, those small cracks and dents can allow water, moisture, and debris to seep in, causing further deterioration.
The good news is that solar panel manufacturers subject their products to rigorous testing to ensure they can withstand the elements. Panels that carry the UL 61730 or IEC 61730 certifications have demonstrated an ability to endure hail impacts of up to 3 inches in diameter traveling at speeds of nearly 90 mph. However, for homeowners and business owners in regions prone to severe hailstorms, such as Texas, Colorado, and Nebraska, taking additional precautions is highly recommended.
Protecting Solar Panels from Hail Damage
One of the most effective ways to safeguard your rooftop solar investment is by choosing high-quality, hail-resistant panels from reputable manufacturers. Look for products that not only carry the necessary UL or IEC certifications but also feature durable construction, thick tempered glass, and weather-sealing features like an IP68 rating.
While most solar panels can withstand light to moderate hail, for homeowners in hail-prone areas, investing in temporary protective coverings could provide an extra layer of security. Hard shell covers offer the best defense, shielding the panels entirely from impact. Padded fabric covers are a more affordable option, helping to dampen the sound and force of hailstones.
Another cost-effective solution is applying a spray-on methacrylate coating to the solar panels. This clear, protective layer can help prevent cracking and chipping without obstructing sunlight. However, it’s crucial to follow the manufacturer’s instructions precisely, as over-application can reduce the panel’s efficiency.
When it comes to high winds, the angle at which solar panels are installed plays a critical role in their resilience. Your roofing professional should carefully calculate the optimal tilt to maximize energy production while also facilitating the rapid shedding of precipitation, including hail and wind-driven rain. This thoughtful design can significantly enhance a solar array’s ability to withstand severe weather events.
Maintaining Solar Panel Performance and Longevity
Even the most durable solar panels require ongoing monitoring and maintenance to ensure they continue operating at peak efficiency, especially after a hailstorm or other extreme weather incident. Roofersinnorthampton.co.uk recommends scheduling regular inspections to check for any visible damage, such as cracks, dents, or debris accumulation.
If you do notice issues, it’s essential to address them promptly. While small cosmetic blemishes may not immediately impact performance, they can ultimately lead to more severe problems down the line. Attempting DIY repairs or modifications, however, is typically not advisable, as it could void the panel’s warranty.
Instead, work closely with your solar installer or a qualified roofing professional to diagnose and remedy any hail-related damage. They’ll be able to assess the extent of the issue, provide guidance on potential insurance claims, and oversee any necessary repairs or replacements to restore your system to full functionality.
Conclusion
Investing in rooftop solar panels is an excellent way to harness clean, renewable energy and reduce your carbon footprint. But in areas prone to severe hailstorms and high winds, homeowners and business owners must take proactive steps to protect their solar arrays from potential damage.
By choosing the right solar panels, implementing temporary protective measures, and maintaining your system through regular inspections and prompt repairs, you can safeguard your investment and ensure your rooftop solar continues to power your property reliably, even in the face of extreme weather events.

Preparing for the Worst: Temporary Solar Panel Covers
As a first line of defense against severe hailstorms, temporary protective covers can be a game-changer for rooftop solar owners. These covers come in two main varieties – hard shell and padded fabric – each with their own unique advantages.
Hard shell covers offer the most robust protection, fully shielding the solar panels from the impact of large hailstones. However, they come with the drawback of blocking sunlight, so your panels won’t be able to generate electricity while the covers are in place.
Padded fabric covers, on the other hand, are a more affordable option that can still help dampen the sound and force of hail striking the panels. These softer barriers allow some sunlight to pass through, ensuring your system can continue producing power, albeit at a slightly reduced capacity.
Regardless of the type of cover you choose, it’s crucial to remember that they are a temporary solution. You’ll need to be diligent about removing the covers once the hailstorm has passed, allowing your solar panels to resume normal operations and maximize energy production.
Optimizing Solar Panel Angles for Hail and Wind Protection
The angle at which your solar panels are installed can play a significant role in their ability to withstand severe weather events, including hail and high winds. Your roofing professional should carefully calculate the optimal tilt to balance energy production with protection against the elements.
Generally, solar panels are angled between 30 and 45 degrees to capture the maximum amount of sunlight throughout the day. However, in hail-prone regions, a slightly steeper angle – around 45 to 60 degrees – can help facilitate the rapid shedding of precipitation, including hail and wind-driven rain.
This increased tilt not only helps prevent accumulated moisture and debris from compromising the panels’ performance but also reduces the surface area exposed to the direct impact of hailstones. By minimizing the vulnerable surface area, you can effectively lower the risk of cracking, chipping, or other types of hail-related damage.
For homeowners with adjustable solar panel mounts, you may even consider temporarily adjusting the angle before an imminent hailstorm, tilting the panels to a steeper position to enhance their protective capabilities. Just be sure to return them to the optimal angle once the severe weather has passed to maintain peak energy output.
Inspecting and Maintaining Solar Panels After Hail Damage
Regular inspections and prompt maintenance are essential for ensuring your rooftop solar panels continue operating at their best, even in the aftermath of a hailstorm. As an experienced roofer, I recommend scheduling a thorough review of your system at least once a year, or immediately following any major weather event.
During these inspections, a qualified professional should carefully examine the solar panels, frames, and associated hardware for any visible signs of damage, such as cracks, dents, or loose connections. They’ll also want to check the overall performance of the system, looking for any drops in energy production that could indicate underlying issues.
If the inspection reveals hail-related damage, it’s crucial to address it without delay. Small cracks or scratches on the panel’s surface may seem innocuous, but over time, they can allow water, moisture, and debris to infiltrate the system, leading to more severe problems. Attempts at DIY repairs, however, should generally be avoided, as they could inadvertently void the panel’s warranty.
Instead, work closely with your solar installer or a reputable roofing company like Roofersinnorthampton.co.uk to diagnose and remedy any issues. They’ll be able to provide guidance on potential insurance claims, as well as oversee any necessary repairs or replacements to restore your system to full functionality.
By staying proactive with inspections and maintenance, you can help ensure your rooftop solar panels continue to harness the power of the sun, even in the face of severe weather challenges.
Choosing the Right Solar Panels for Hail and Wind Protection
When it comes to protecting your rooftop solar investment from the ravages of hail and high winds, the solar panels themselves play a crucial role. Fortunately, today’s solar technology is more resilient than ever, with manufacturers subjecting their products to rigorous testing to ensure they can withstand the elements.
The gold standard for hail resistance is the UL 61730 or IEC 61730 certification. Panels that carry these marks have demonstrated the ability to withstand the impact of hailstones up to 3 inches in diameter, traveling at speeds of nearly 90 mph. This level of resilience means your solar array is well-equipped to handle even the most severe hailstorms.
In addition to the hail-resistance rating, you’ll also want to look for solar panels with a sturdy, weather-sealed construction, including an IP68 rating. This designation indicates that the panels are both waterproof and dust-proof, providing an extra layer of protection against the elements.
While the upfront cost of these high-quality, hail-resistant solar panels may be slightly higher, the peace of mind and long-term durability they provide are well worth the investment, especially for homeowners and businesses in regions prone to extreme weather events.
As you research and compare solar panel options, be sure to work closely with a reputable installer like Roofersinnorthampton.co.uk.

Navigating Solar Panel Warranties and Insurance Coverage
When it comes to protecting your rooftop solar investment, understanding the ins and outs of warranties and insurance coverage is crucial. Unfortunately, many solar panel manufacturers exclude hail damage from their product warranties, leaving homeowners and business owners vulnerable to the potentially high costs of repairs or replacements.
That’s where your homeowner’s or commercial property insurance policy comes into play. In most cases, standard policies will cover damage to rooftop solar panels caused by hail or other severe weather events. However, it’s essential to review the details of your coverage carefully, paying close attention to any exclusions or limitations that may apply.
If your solar panels are not adequately protected under your existing insurance policy, you may need to consider expanding your coverage or purchasing a separate policy specifically for your renewable energy system. While this added expense may seem daunting, it can provide invaluable peace of mind and financial protection in the event of a hailstorm or other catastrophic weather incident.
Regardless of your insurance situation, maintaining detailed documentation and photographic evidence of any hail-related damage to your solar panels can greatly streamline the claims process. By having this information on hand, you can help ensure a smooth and successful resolution, minimizing the disruption to your renewable energy system and your daily operations.
