Solar Panel Repair & Maintenance FAQ

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.

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.

What are solar panel arc faults, and how are they prevented?

An arc fault in a solar panel system is a dangerous electrical hazard that occurs when electricity jumps or arcs between conductors. This can happen due to damaged or loose wiring, faulty connections, or other electrical issues. Arc faults generate intense heat and can ignite flammable materials, posing a significant fire risk. To prevent arc faults:

• Use high-quality wiring and components.
• Ensure proper installation by a qualified electrician.
• Install arc-fault circuit interrupters (AFCIs) in your solar panel system. AFCIs are safety devices designed to detect and interrupt arc faults, protecting your system and property from fire hazards.
• Regularly inspect wiring and connections for any signs of damage or looseness.

How do I know if my solar inverter is working properly?

You can tell if your solar inverter is working properly by:

• Checking the Display: Most inverters have a display screen that shows real-time energy production, system status, and any error codes. If the display is blank or shows an error message, it indicates a problem.
• Monitoring Energy Production: Use your solar monitoring system (if you have one) to track energy production. If you notice a significant drop in output, it could be due to an inverter issue.
• Listening for Unusual Noises: Buzzing, humming, or clicking sounds from the inverter can signal a problem.
• Checking for Overheating: Inverters can overheat, especially in hot weather. If the inverter feels excessively hot to the touch, it may be malfunctioning.

If you suspect your inverter is not working properly, contact a qualified solar technician for diagnosis and repair.
