Solar Panel Repair & Maintenance FAQ

What should I do if my solar panels are damaged?

If your solar panels are damaged:

1. Safety First: Do not attempt to repair the panels yourself. Solar panels generate electricity, even when damaged, and can pose an electrical shock hazard.
2. Shut Off the System: If possible, turn off the solar system at the main disconnect switch. If you are unsure how to do this, consult with your installer or a qualified electrician.
3. Document the Damage: Take clear photos or videos of the damage for insurance purposes.
4. Contact Your Installer or a Repair Specialist: Get in touch with your solar installer or a qualified solar panel repair company to assess the damage and provide repair options.
5. Contact Your Insurance Company: If the damage is due to a covered event, such as a hailstorm or falling debris, file a claim with your insurance company.

It's crucial to address any damage to your solar panels promptly to prevent further damage, ensure safety, and minimize disruption to your energy production.

What causes solar panel microcracks?

Microcracks in solar panels are tiny, hairline cracks in the solar cells that can reduce the panel's efficiency. They may not be visible to the naked eye, but they can be detected using specialized equipment. These microcracks can occur due to various factors:

• Manufacturing Defects: Some panels may have tiny cracks from the manufacturing process.
• Thermal Stress: Temperature fluctuations, especially rapid heating and cooling, can stress the panels and cause microcracks.
• Mechanical Stress: Impact from hail, falling debris, or improper handling during installation can lead to microcracks.
• Transportation and Handling: Rough handling during transportation or installation can also cause stress fractures.

While some microcracks are unavoidable, choosing high-quality panels from reputable manufacturers and ensuring careful handling and installation can minimize the risk.

Can a power surge damage my solar panels?

Yes, power surges can potentially damage your solar panel system, particularly the inverter. A power surge is a sudden increase in voltage that can overload electrical equipment. Power surges can occur due to:

• Lightning Strikes: A direct or nearby lightning strike can induce a powerful surge in electrical lines.
• Grid Issues: Fluctuations or disruptions in the power grid can cause surges.
• Faulty Wiring: Damaged or poorly installed wiring within your home or solar system can create surge conditions.
• Malfunctioning Appliances: Some appliances, such as refrigerators or air conditioners, can create surges when they cycle on or off.

To protect your solar system from power surges:

• Surge Protectors: Install surge protectors at the main electrical panel and at the point where your solar system connects to the grid.
• Grounding: Ensure your solar system is properly grounded to provide a path for excess current to flow safely to the earth.
• Lightning Protection (if necessary): In areas prone to lightning strikes, consider installing a lightning protection system to divert lightning strikes away from your home and solar system.

Taking these preventive measures can help safeguard your valuable solar investment from damage caused by power surges.

Are solar panel repairs covered by warranty?

Whether or not your solar panel repairs are covered by warranty depends on the specific terms of your warranty and the nature of the damage. Most solar panel manufacturers offer warranties that cover defects in materials and workmanship for a specified period, typically 10-25 years. If a panel fails due to a manufacturing defect, the warranty will likely cover the cost of replacement. However, warranties typically do not cover damage caused by external factors, such as:

• Severe weather (hail, wind)
• Falling debris (trees, branches)
• Improper installation
• Neglect or lack of maintenance

It's crucial to review your warranty documents carefully to understand what is and is not covered.
