Because solar panels rely on light, not heat, they can still generate power on cloudy or rainy days at a reduced capacity. On average, they produce 10% to 25% of their normal energy output under overcast conditions. While solar energy thrives in bright, sunny environments, that doesn't mean it. . Given that solar panels generate electricity from the sun, many property owners wonder if solar panels still work, even on cloudy or rainy days. During rain, clouds block direct sunlight, reducing the intensity of light reaching solar panels.
