Solar Panel Repair & Maintenance FAQ

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.

How does snow affect my solar panels?

Solar panels can still generate some electricity in snowy conditions, but their output will be significantly reduced. Snow covering the panels blocks sunlight from reaching the solar cells, hindering energy production. In most cases, snow will naturally slide off solar panels due to their smooth surface and angled tilt. The heat generated by the panels when exposed to sunlight can also help melt the snow. However, in regions with heavy snowfall, you may consider:

• Using a Roof Rake: Carefully remove snow from the panels using a roof rake designed for this purpose. Avoid using abrasive tools or excessive force that could damage the panels.
• Hiring a Professional: If you are uncomfortable removing snow from your roof or if your panels are difficult to access, consider hiring a professional solar panel cleaning or maintenance company.

It's important to prioritize safety when dealing with snow on your roof. Never walk on a snow-covered roof, as it can be extremely slippery and dangerous.

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.

What are the common signs that my solar panels need repair?

Here are some common signs that your solar panels may need repair:

• Drop in Energy Production: If you notice a significant decrease in your solar system's energy output, it could indicate a problem with the panels, inverter, or wiring.
• Visible Damage: Cracks, chips, or other visible damage to the panels require immediate attention.
• Error Codes or Warning Lights: If your inverter displays error codes or warning lights, it signals a malfunction that needs to be addressed.
• Unusual Noises: Buzzing, humming, or crackling sounds coming from the panels or inverter can indicate a problem.
• Loose or Damaged Wiring: Inspect the wiring connections for any signs of looseness, damage, or corrosion.

If you notice any of these signs, it's essential to contact a qualified solar panel repair specialist promptly to diagnose and resolve the issue.
