Solar Panel Repair & Maintenance FAQ

Can solar panels be damaged by hail?

Solar panels are generally designed to withstand hailstorms, but the extent of damage depends on the size and intensity of the hail. Most solar panels undergo testing to ensure they can withstand impacts from hailstones of a certain size. However, larger or more forceful hailstones can crack or damage panels. If you live in a hail-prone area, consider:

• Choosing impact-resistant solar panels: Some manufacturers offer panels specifically designed for enhanced hail resistance.
• Protecting your panels during hailstorms: If a hailstorm is forecast, consider covering your panels with a protective barrier, such as a tarp or plywood, if feasible.
• Inspecting panels after a hailstorm: After a hailstorm, carefully inspect your panels for any signs of damage.

If your panels are damaged by hail, contact your solar installer or a repair specialist. Your insurance may cover hail damage, so it's important to document any damage and file a claim.

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.

What are solar panel ground faults?

A ground fault in a solar panel system occurs when electricity flows outside of its intended path, typically to the ground. This can happen due to:

• Damaged wiring
• Faulty connections
• Water intrusion
• Other insulation breaches

Ground faults can be dangerous, as they can:

• Cause electric shock
• Start a fire
• Damage equipment

To prevent ground faults:

• Ensure proper grounding of the system
• Regularly inspect wiring for damage
• Address water leaks promptly

Modern solar systems often incorporate ground fault protection devices (GFPDs) that automatically shut off the system in the event of a ground fault, enhancing safety.

Can solar panels cause roof leaks?

Solar panels themselves do not cause roof leaks. However, if the panels are not installed correctly, they can create vulnerabilities that lead to leaks. Common causes of leaks associated with solar panel installations include:

• Improper Flashing: Flashing is a thin, waterproof material used to seal gaps and prevent water intrusion around penetrations in the roof, such as vents, chimneys, and solar panel mounts. If flashing is installed incorrectly, water can seep through the roof.
• Damaged Roof Shingles: If roof shingles are damaged during the installation process, it can create openings for water to enter.
• Improper Sealant Application: Sealant is used to create a watertight barrier around solar panel mounts and other roof penetrations. If the sealant is not applied correctly, it can deteriorate and allow water to leak through.

To prevent leaks, it's crucial to choose a reputable and experienced Solar Panel Repair & Maintenance who:

• Uses high-quality flashing and sealants
• Follows industry best practices for installation
• Has a thorough understanding of roofing systems.

Regular roof inspections and maintenance can also help identify potential leak issues early on.
