Did you know that solar panels work even in winter weather? Believe it or not, solar panels do better than you might think in the cold. Low temperatures won’t stop the panels converting available sunlight to power. The one Achilles heel for solar panels is cloudy weather. Although the system can still produce 10 – 25% of their typical output, the amount of production is less than during summer months of direct sunlight. Most solar panel systems are installed at an angle. This is by design so that snow will easily slide off on its own.
