Solar Panel Repair & Maintenance FAQ

What are the most common solar panel problems?

Some of the most common solar panel problems include:

• Panel Degradation: Over time, solar panels naturally lose some efficiency, typically less than 1% per year.
• Shading: Objects, like trees, buildings, or even bird droppings, can block sunlight from reaching the panels, reducing their output.
• Microcracks: Tiny cracks in the solar cells can affect performance. These cracks may not be visible to the naked eye.
• Inverter Issues: Inverters can malfunction due to various reasons, including overheating, electrical surges, or component failure.
• Wiring Problems: Loose, corroded, or damaged wiring can disrupt the flow of electricity from the panels to the inverter.
• Roof Leaks: Water damage from roof leaks can affect the panels and wiring.
• Pest Infestation: Rodents or birds can sometimes damage wiring or nesting under panels.

Regular inspections and maintenance can help prevent or detect many of these problems early on.

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.

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.

How much does it cost to repair solar panels?

The cost of solar panel repair can vary depending on the extent of the damage, the type of repair needed, and labor costs in your area. Some common repair costs include:

• Panel Replacement: Replacing a single damaged panel can cost [estimated range].
• Inverter Repair or Replacement: Repairing or replacing an inverter can cost [estimated range].
• Wiring Repair: Fixing faulty wiring connections typically costs [estimated range].
• Troubleshooting and Diagnostics: The cost for a professional to diagnose the problem can range from [estimated range].
