Claims that solar panels only work when the sun is shining are misleading. Solar panels continue to generate electricity even in cloudy or rainy conditions, and cold weather can actually improve their efficiency.(1)Solar panels are designed to capture both direct and diffuse sunlight, meaning they can still produce energy during cloudy or overcast conditions. While cloud cover can reduce solar energy output by up to 45%, they remain functional and still generate a significant amount of electricity.(2) Countries with significant cloud cover and cold climates, such as Germany and Canada, successfully use solar energy to contribute to their power grids. This demonstrates that solar technology is adaptable and reliable in various weather conditions.(3)Cold weather does not reduce solar panel performance—in fact, it can enhance it. Research shows that colder temperatures improve voltage output, leading to better overall efficiency. Studies indicate that solar panels perform more efficiently in cooler climates due to improved electrical performance.(4) Crystalline silicon cells, which dominate the U.S. market, are particularly well-suited for colder environments.(5)
