Imagine an unexpected hail storm pelts your neighborhood, leaving behind a trail of destruction. Cars dented, roofs battered, and windows shattered. But what about your panels? Can hail damage solar panels?
At Wolf River Electric, where solar solutions meet innovation, we’ve seen the havoc nature can wreak on our energy systems. Hail damage on solar panels isn’t just a theoretical concern—it’s a real threat to your investment in renewable energy.
We’ll dive into the risks, realities, and solutions surrounding hail and solar panels, shedding light on what you need to know to safeguard your sustainable power source.
How Hail Can Damage Your Solar Panels
Hail can cause solar equipment damage
Hail, depending on its size and speed, can harm solar panels. When hailstones strike the panels, they can create dents, scratches, or even crack the glass covering. These impacts compromise the structural integrity of the panels, potentially leading to reduced efficiency or, in severe cases, rendering them inoperable.
Luckily, most solar panels have higher impact resistance and tempered glass, specifically designed to withstand hail impact. Otherwise, you may still want to take extra precautions to reduce the direct force of hailstones.
Hail can reduce solar panel system performance
Even minor damage caused by hail can affect the efficiency of solar panels over time. Cracks or scratches on the glass can disrupt the panel’s ability to convert sunlight into electricity. While small damages may not immediately affect performance, accumulated effects might gradually reduce the power production from your solar energy system.
Warranty limitations
Most solar panel warranties cover manufacturing defects and performance guarantees, but they might have limitations regarding damage caused by external factors like hail. Some warranties specifically exclude coverage for solar panel hail damage, especially if they were not explicitly marketed as hail-resistant.
It’s essential to carefully review the solar panel warranty terms and understand the coverage limitations of hail damage before purchasing solar panels. Investing in panels with better warranties that include hail damage coverage or considering additional insurance might provide peace of mind against such instances.
Additional insurance costs
While homeowner insurance often covers solar panels, coverage for hail damage might vary. Some insurance policies might require additional coverage for specific perils like hail damage to ensure full protection for your solar system. Of course, the additional coverage automatically results in extra insurance costs.
Before installing solar panels, review your insurance policy thoroughly, and if necessary, consider adding endorsements or specialized coverage to safeguard your solar investment against potential hail damage.
Hail can lead to microcracks in solar panels
Hail impact can create microcracks on the surface of solar panels, which might not be immediately visible but can worsen over time. These tiny fractures can weaken the panel’s integrity, making it more susceptible to moisture penetration.
Over time, moisture ingress due to microcracks can corrode internal components, reducing the panel’s efficiency and potentially causing electrical issues. Regular inspections by professionals can detect these microcracks early, allowing for timely repairs to prevent further damage.
Hail can disrupt the balance of solar cells
The impact of hailstones can disrupt the balance of solar cells within the panels. Solar panels consist of interconnected solar cells that work together to generate electricity. When hail hits the panel, it can damage or displace these cells, affecting the overall performance of the panel.
Even if the physical structure remains intact, the displacement or damage to these cells can hinder the panel’s ability to produce electricity efficiently.
Avoiding Hail Damage On Rooftop Solar Panels
Choose high-quality solar panels
Opt for solar panels with high impact resistance and durable construction. Look for panels made with tempered glass and sturdy frames designed to withstand hail damage.
Research panel manufacturers known for producing hail-resistant models. Investing in high-quality panels upfront can significantly reduce the risk of damage during hail storms.
Use a temporary protective cover
Consider using temporary protective covers specifically designed for hail storms. At the hardware stores, the covers are made of durable materials and can shield your solar panels during severe weather events. Ensure the covers fit securely over the panels and are installed correctly before a hail storm is forecasted. Once the storm passes, remove the covers promptly to restore normal solar panel functionality.
Inspect solar panels after a hail storm
After a hailstorm, conduct a thorough inspection of your solar panels. Check for any visible signs of damage, such as dents, cracks, or scratches on the panel surface.
If you notice any damage, document it and consider contacting a professional to assess the extent of the damage and perform necessary repairs. Most importantly, timely inspections will help detect and address hail-related damage early, preventing further complications.
Spray on a methacrylate layer
Consider applying a methacrylate-based protective coating to the surface of your solar panels. The transparent layer acts as a shield, protecting against hail damage. If you need to be sure, follow manufacturer guidelines carefully when applying this coating to get proper adhesion and coverage. However, due to weathering or wear, this method might require reapplication over time.
Protect the panels with wire mesh
Include wire mesh screens or guards over the solar panel installation to act as a physical barrier against hailstones. These mesh guards should be securely attached to the panel frames without obstructing sunlight.
Choose a mesh size that effectively blocks hailstones while allowing sufficient airflow for proper panel ventilation. Plus, regularly inspect the mesh to ensure it remains intact and free from debris that could hinder its protective function.
Adjust your solar panel angles
Adjusting the tilt or angle of your solar panels can minimize direct exposure to hail. While it won’t entirely prevent hail damage, angling the panels slightly can reduce the impact force of hailstones.
The best way is to consult a professional or follow manufacturer recommendations to safely adjust the panel angles of the solar panels installed. Changing the angles might slightly affect the panel’s energy production, so consider this adjustment carefully.
