How does solar power generation work in rainy days

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. . Solar panels continue to generate electricity even when the sky is overcast and rain is falling, though performance is noticeably diminished compared to a bright, sunny day. While efficiency may dip slightly during. . One of the most common questions about solar energy is whether solar panels work in the rain or during cloudy weather. It's a valid concern—especially for regions with long monsoon seasons or frequent overcast skies.
