Solar panels are known for their durability and long-lasting performance, often lasting 25 to 30 years with proper care. The lifespan depends on panel quality, environmental conditions, and maintenance. Like any other outdoor equipment, they are not immune to damage. Over time, solar panels can experience wear and tear, leading to cracks, chips, or other forms of damage. While they are designed to withstand harsh weather, certain conditions like hail, wind, and even manufacturing defects can cause harm.

In this blog, we will discuss common causes of solar panel damage, how to identify the signs of a damaged panel, and the immediate steps you should take to protect your system.

Common Causes of Solar Panel Damage

1. Hail Damage

While not the most frequent cause of solar panel issues, hail can be a significant risk in certain regions. Most modern solar panels are constructed with high-strength tempered glass and tested to withstand hail up to one inch in diameter at high speeds. However, exceptionally large hailstones or rare, severe storms can still cause surface damage, such as chips or cracks.

2. Wind Damage

High winds can stress mounting systems, especially if the solar panels were not installed according to best practices. In extreme weather events—such as hurricanes or tornadoes—there is a small risk of panels detaching or sustaining structural damage. Proper installation and secure mounting are critical to preventing wind-related issues.

3. Other Causes

  • Poor Installation: Improperly installed panels are more prone to damage over time. Incorrect alignment or faulty mounting can lead to stress fractures or other issues.

  • Falling Debris: Branches, rocks, or other debris can fall on the panels, causing physical damage.

  • Manufacturing Defects: Although rare, some solar panels might have defects that lead to early damage.

  • Ageing: Over time, solar panels experience a gradual reduction in efficiency, typically around 0.5–1% per year. While they do not usually become physically fragile, prolonged exposure to harsh weather and lack of maintenance can increase the likelihood of minor wear and tear.

Signs of Broken or Damaged Solar Panels

  • Cracks or Chips: Inspect your panels for visible cracks, chips, or other surface damage.

  • Discoloration: If you notice any strange colours or spots on the panels, it could indicate damage.

  • Inconsistent Power Output: A damaged panel may produce less energy or have an unstable output. This can be an early indicator that something is wrong.

  • Loose Connections: If you notice any loose wiring or if the mounting system seems off, it could be a sign of damage to the structure of your solar array.

Monitoring systems (e.g., inverters with performance tracking) can help detect output drops early.

Immediate Steps to Take if You Notice Damage

If you suspect that your solar panels are damaged, here are the steps you should follow:

  • Turn Off the System: Safety should always come first. If you notice visible damage to your panels or electrical components, shutting down your solar power system is a smart precaution. Modern systems often include built-in safety shutoff mechanisms, but any manual disconnection or repair should only be carried out by a certified electrician.

  • Inspect the Damage: Conduct a visual inspection of the panels and other system components. Look for cracks, loose wires, or any abnormalities. However, avoid touching the panels, especially if they are still connected. While it is safe to inspect from a distance, avoid climbing on roofs or touching panels.

  • Contact a Professional: If you notice any signs of damage, it’s crucial to call a certified solar technician. They can thoroughly evaluate the extent of the damage and suggest whether repair or replacement is necessary.

  • Temporary Protection: If possible, cover the damaged panel with a tarp or protective cover to prevent further harm from rain, dust, or debris until a professional can assess the situation.

Repair vs. Replacement: Making the Right Choice

Once the damage is confirmed, the next step is deciding whether to repair or replace the panel.

  • Minor Damage: Small chips, cracks, or loose wiring can often be repaired by a professional technician. These repairs are generally affordable and quick to complete.

  • Severe Damage: If the panel is severely cracked or shattered, or if it has lost a significant amount of efficiency, replacing it might be the better option. If your panel is out of warranty and significantly degraded, replacing it is often more cost-effective than patching it.

Cost Considerations

Understanding the cost implications is essential when deciding whether to repair or replace a damaged solar panel. Prices can vary widely based on the severity of the issue, the panel type, and the service required. Here are the key factors that influence the total cost:

  • Extent of Damage: More severe damage naturally costs more to fix.

  • Type of Panel: Some panels are more expensive to replace due to their technology or size

  • Labour Costs: Hiring a certified professional can add to the cost, but it ensures the job is done correctly and safely.

Preventing Future Solar Panel Damage

  • Weather-Proofing: Investing in protective covers or anti-hail shields can help safeguard your panels from extreme weather events. These additional barriers can significantly reduce the risk of impact damage.

  • Regular Maintenance: Routine inspections and cleaning can help catch minor issues before they become major problems. Keeping your panels clean also ensures they operate at peak efficiency.

  • Choosing Quality Panels: Opt for high-quality, durable solar panels from trusted manufacturers. While they may have a higher upfront cost, they are more likely to withstand harsh conditions and last longer.

  • Insurance Coverage: Insuring your solar panel system can offer valuable protection against unforeseen events. While rooftop panels are often included under standard homeowners’ insurance, coverage details vary. Ground-mounted systems or leased panels may require separate policies or riders. It’s best to confirm your coverage options with your insurance provider.
