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.

Can I clean my solar panels myself?

While it's possible to clean your solar panels yourself, it's important to do so with caution. Here are some tips for safe and effective DIY solar panel cleaning:
  • Choose a Cool, Overcast Day: Avoid cleaning panels in direct sunlight or when they are hot, as the cleaning solution can dry too quickly and leave streaks.
  • Use a Soft Brush or Sponge: Avoid abrasive materials that could scratch the panels. A soft-bristled brush or a non-abrasive sponge is ideal.
  • Use Mild Soap and Water: A gentle cleaning solution of mild soap (dish soap) and water is usually sufficient. Avoid using harsh chemicals or detergents.
  • Rinse Thoroughly: Rinse the panels thoroughly with clean water to remove any soap residue.
  • Safety First: Be careful when working on your roof. Use a sturdy ladder and consider wearing a safety harness. If you are uncomfortable working on your roof, it's best to hire a professional.
If you have any concerns about cleaning your solar panels yourself, it's always recommended to consult with a professional solar panel cleaning company. They have the experience, equipment, and safety training to clean your panels thoroughly and effectively.

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.
