Solar Panel Productivity During Winter

Will solar panels work effectively in cold climates or during the snow-heavy winter season?

A lot of would-be solar panel homeowners often ask this question. A commonly held belief is that solar panels do not work during the snowy winter season. But that’s actually a myth! In fact, your solar panels work year-round even during winter as long as they’re not covered in heavy snow for an extended period of time.

Sunlight penetration on solar panels is affected by heavy snowfall, but electricity production is sustained throughout winter. Why? Most solar panels are manufactured with anti-reflective glass to absorb maximum sunlight. This produces more heat thus melts snow easily than a regular roof. This allows solar panels to continue producing power.

It’s also worth noting that solar panels are designed for maximum durability, allowing to withhold 20-40 lbs. of weight per square foot. And snow isn’t usually that heavy to be posing a risk on your panels’ durability.

You can even opt for high-pressure ratings if your place sees a lot of snowfall.
