Do Solar Panels Work in the Winter? Insights from New England Solar and Green Inc., Williamstown

Based in Williamstown, MA, New England Solar and Green Inc. frequently encounters questions about how solar panels function during the chilly and snowy New England winters. The great news? Solar panels work really well—even in winter. Here’s a breakdown of what to anticipate and how to maximize your solar energy system’s performance all year.

How Solar Panels Perform in Winter

1. Increased Efficiency in Cold Temperatures

Unlike common perception, solar panels function better in cold temperatures. Hot weather, like that in summer, may decrease their efficiency, but cooler air allows them to transform sunlight into power more successfully. Provided they get sunlight, cold weather itself doesn’t negatively impact how well they work.

2. Snow and Ice: Temporary But Manageable

Yes, snow can block sunlight temporarily. However, most panels are installed at an angle, which helps snow slide off naturally. In addition:

• Panels absorb heat from the sun and typically melt snow faster than a standard roof.
• Even under a thin snow layer, some light can pass through and generate electricity.
• Anti-reflective coatings on panels also aid in snow shedding.

3. Fewer Daylight Hours = Less Overall Production

It’s often thought otherwise, however, solar panels perform better when it’s cold. Summer’s high heat can decrease their effectiveness, but cooler air aids them in turning sunlight into electricity more efficiently. As long as they get sunlight, cold weather by itself won’t negatively affect how they work.

4. Winter Maintenance Tips

Regular upkeep ensures your panels perform at their best:

• Clear snow gently with a soft tool like a roof rake with a rubber edge. Avoid metal tools that could damage the panels.
• If snow is heavy or hard to access, consider professional cleaning for safety.
• Inspect the system for any buildup of debris or ice dams around the mounts.
