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.

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.

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.
