Solar Panel Repair & Maintenance FAQ

Find answers to frequently asked questions about Solar Panel Repair & Maintenance and connect with qualified professionals in USA through SolarCompaniesHub.

How often do solar panels need to be maintained?

It's generally recommended to have your solar panels inspected and maintained at least once a year. A professional inspection can identify potential problems early on, such as loose wiring, damaged panels, or shading issues. Regular maintenance can also include panel cleaning to ensure optimal efficiency.

Do solar panels work in the winter or on cloudy days?

Solar panels still generate electricity on cloudy days, although their output will be lower than on sunny days. The amount of electricity generated depends on the intensity of the sunlight. In winter, solar panels will produce less energy due to shorter daylight hours and lower sun angles. However, even in cloudy or snowy conditions, solar panels can still capture some diffused sunlight and generate a portion of their rated output.

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.

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.
