Yes - solar panels work on cloudy days. They produce 10-70 % of their rated output depending on cloud thickness, because they use diffuse (scattered) light, not just direct sunbeams.
Modern panels reach 18-23% efficiency. That means they convert about one-fifth of sunlight into usable power. But efficiency is only part of the story. Real-world performance changes with temperature, shading, tilt angle, and even the quality of the inverter or battery.
Solar panels generally operate at about 70% to 80% of their peak efficiency in winter. Low temperatures improve panel performance by reducing electrical resistance, often increasing efficiency by roughly 5% for every 18°F (10°C) drop, as long as the panels receive unobstructed.
