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.

How does shading affect solar panel efficiency?

Shading can significantly reduce the efficiency and energy output of solar panels. Even partial shading on a single panel in a string can impact the performance of the entire string. When a solar cell is shaded, it acts as a resistor, reducing the current flow in the entire circuit. This is why it's crucial to choose a solar panel system that incorporates:

• Microinverters or Power Optimizers: These devices can mitigate the effects of shading by optimizing the output of each individual panel.
• Strategic Panel Placement: A qualified installer will assess your roof and design a system layout that minimizes potential shading from trees, buildings, or other obstructions.

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.

What are the different types of solar panel warranties?

Solar panel manufacturers typically offer two types of warranties:
Product Warranty: This warranty covers defects in materials and workmanship for a specified period, typically 10-25 years. It ensures that the panels will be free from manufacturing defects that affect their performance.
Performance Warranty: This warranty guarantees a minimum level of power output from the panels over a specified period, usually 25 years. It ensures that the panels will maintain a certain level of efficiency over their lifetime.
The length and coverage of these warranties can vary by manufacturer and panel type. It's important to review the warranty details carefully before purchasing panels.
