Common Problems with Solar Panels on Your Roof

If you have solar panels on your home, you know the world of benefits these structures can produce for your lifestyle, energy bill, and carbon footprint. Solar panels are an excellent investment, and millions of homeowners nationwide are switching to solar power every year.

Unfortunately, solar panels can experience problems just like any other outdoor structure. Precipitation, improper installation, and lack of maintenance can all create issues that will affect how your solar system generates power and how long your panels last.

Common Problems with Solar Panels on Your Roof

However, becoming aware of common solar panel problems can help you identify any issues as they occur so that you can schedule repairs before they worsen. Read on to learn about a few common problems with solar panels and steps you can take to prevent them.

Common Problems with Solar Panels


Solar panels often disrupt water flow on the roof, creating leakage issues. Traditional roof tiles utilize specific designs and builds to allow precipitation to flow freely from the tiles to the gutters and down the drainage spout. However, adding solar panels on top of roof tiles prevents water from ever reaching the tiles, creating inefficient flow and seepage into the roof. While proper solar panel installation can prevent a disruption of water flow, many contractors fail to account for water flow during installation. As a result, leaks are a common solar panel problem for many homeowners. “Snail Trails” Another common issue with solar panels is snail trails. Solar panels utilize a sleek, silicon wafer surface that maximizes solar PV and produces the most energy from the sun. Unfortunately, this panel material often allows for discoloration to occur over time, which researchers refer to as “snail trails.” Snail trails are dark brown lines or areas of discoloration that occur after several years of solar power production. These trails occur when moisture seeps through the back sheet and diffuses into the glass cell surface. While snail trails do not affect solar power production, they may indicate deeper issues—such as micro-cracks—that can impact energy generation. As a result, if you notice snail trails on your solar panels, you may want to schedule an inspection. Micro-Cracks in the Solar Cells Micro-cracks, also known as micro-fractures, are small cracks in the silicon within solar cells. These cracks may occur for various reasons, including:

  • Extreme temperature changes
  • Humidity
  • Harsh precipitation
  • Heavy snowfall
  • Manufacturing defects
  • Incorrect packaging and handling
  • Improper installation

Micro-cracks in solar panels can lead to inactive cell parts, causing a portion of the panel to stop generating energy. However, some micro-cracks do not produce any adverse effects on energy production. If you notice micro-cracks on your solar panel or suspect that your energy production has diminished, scheduling an inspection with your installer can help determine the best next steps.

Internal Corrosion

Internal corrosion occurs when moisture seeps into the solar module. If the module is not air- and water-tight, water can easily penetrate the inner structure after installation. Manufacturers should conduct quality control tests to ensure that each module meets lamination and production standards to prevent corrosion. However, some manufacturers overlook these standards, setting homeowners up for issues with their solar panels down the line.
