Solar panels have quickly become a popular choice for homeowners and businesses alike. They are a fantastic way to harness the power of the sun to generate electricity, reduce carbon footprints, and contain energy costs. However, as the frequency of severe weather events such as hailstorms increases, it’s crucial to understand the potential impact on solar panels.
At Glo Renewables in sunny Devon, UK, we’re committed to providing you with the necessary information to keep your solar panels in tip-top shape, come rain or shine (or hail, in this case). So, buckle up and get ready to unravel the mysteries of hail’s impact on solar panels in this comprehensive study. We’ll offer helpful tips, insights, and plenty of solar wisdom along the way.
Understanding Hail Damage
Hail varies in size, with hailstones as small as peas and as large as grapefruits. The size of hailstones directly affects the potential damage to solar panels. Therefore, it’s crucial to understand the anatomy of a solar panel and its varying vulnerabilities to hail impact.
The Structure of Solar Panels
Solar panels consist of several components, including:
Tempered Glass
This is the most visible part of the solar panel, acting as a protective barrier for the inner workings. The tempered glass covers the solar cells and is usually the most susceptible to hail damage. Those larger hailstones can cause cracks or even shatter the glass entirely.
Solar Cells
These tiny powerhouses are the heart and soul of your solar panel, where the magic of converting sunlight into electricity happens. While the glass shields them from direct impact, large hailstones or complete panel breakage could still affect their performance.
Electrical Components
These include the wires, connectors, and junction boxes that allow your solar panel to function properly. They’re typically well-protected, but in severe cases of hail damage, they could be compromised, too.
Impact of Hail Damage on Solar Panel Performance
Hail damage can affect the performance of your solar panels in several ways:
- Reduced Power Output: Cracked or broken glass reduces the amount of sunlight reaching the solar cells, leading to lower electricity generation.
- Hot Spots: Cracks in the panel can create hot spots, further reducing efficiency and potentially posing a safety risk. Nobody wants a hot, underperforming panel on their hands.
- Complete Failure: In severe cases, hail can completely damage a panel, rendering it inoperable.
Post-Hailstorm Inspection: A Crucial Step
Even if no visible damage is apparent after a hail storm, inspecting your solar panels is essential. Look for cracks or chips in the tempered glass, discolouration or burn marks on the back sheet, and compare power output data to pre-hailstorm figures. If you notice a significant decrease in power output, your panels may have sustained damage that isn’t visible to the naked eye.
Repairing or Replacing Hail-Damaged Solar Panels
If your panels have been damaged by hail, it’s important to assess the severity of the damage and decide on the best course of action.
For minor cracks, repair may not be necessary immediately, but you should monitor the panels for further damage.
More extensive cracks or damage likely require professional repair or panel replacement. Always use qualified solar panel technicians for repairs or replacements to ensure the safety and efficiency of your system.
Protecting Your Solar Panels from Hail Damage
While your solar panels are designed to be tough cookies, able to withstand the impact of hail, there’s no harm in giving them a little extra protection. After all, we want to safeguard your investment and ensure those panels keep soaking up the sun for years to come. That’s why we recommend considering some additional protective measures:
Hail Guards: These nifty mesh screens or structures are installed above your panels, acting as a shield against those pesky hailstones. They’re like a big brother protecting your solar panels from bullies on the playground.
Impact-Resistant Glass: While not as common, some manufacturers offer solar panels with specially designed glass that’s extra resistant to hail impact. It’s like giving your panels a super-tough suit of armour to withstand even the most aggressive hailstorm.
Remember, it’s crucial to consult with a reliable solar provider like Glo Renewables before implementing any protective measures to ensure they won’t impact your system’s performance or void your warranty.
Warranties and Insurance
Now, let’s talk about warranties and insurance – because, let’s be honest, nobody wants to be left high and dry if something goes wrong. Understanding the limitations of your solar panel warranty is essential. Many warranties do not cover damage related to hailstorms, which means you could be left footing the bill for repairs or replacements.
That’s why it’s crucial to have a discussion with your insurance provider and ensure that your homeowner’s policy covers your solar panels.
By taking the time to understand your warranty and insurance coverage, you can rest easy knowing that your solar investment is protected, come rain, shine, or hail. And let’s face it, peace of mind is priceless when it comes to your renewable energy journey.
In Summary
While hail can damage solar panels, impacting performance and potentially leading to safety hazards, this is a relatively rare occurrence. Proper installation, regular maintenance, and protective measures can all help mitigate the risk of hail damage.

Key FAQs on Solar Panels and Hail Impact: What You Need to Know
1. How does hail affect solar panel efficiency?
Hail can cause micro-cracks in solar panels, reducing their efficiency. Larger hailstones may even break the glass, leading to significant power output loss. It’s important to inspect panels after a hailstorm to ensure they’re functioning properly.
2. What should I do if my solar panels are damaged by hail?
If you notice any damage after a hailstorm, contact a professional solar technician to assess the extent. Minor cracks might not require immediate action, but significant damage could necessitate repairs or replacement.
3. Can solar panels withstand hailstorms?
Most solar panels are designed to withstand hail up to a certain size, typically tested under controlled conditions. However, unusually large or dense hailstones can still cause damage.
4. Are there any protective measures for solar panels against hail?
Yes, you can install hail guards or use solar panels with impact-resistant glass. These measures can provide additional protection against hail damage.
5. Will my warranty cover hail damage to solar panels?
Warranty coverage for hail damage varies by manufacturer and policy. It is crucial to review your warranty details and consider additional insurance coverage for your solar panels.
6. How can I ensure my solar panels are protected from hail?
Regular maintenance, protective installations like hail guards, and comprehensive insurance policies are key to safeguarding your solar panels from hail damage.
