The Role of Sunlight in Solar Energy Production

The best conditions for solar energy production are clear, sunny days with high solar irradiance. Ideal locations are those with many peak sun hours, minimal cloud cover, and cooler temperatures that help maintain panel efficiency. However, solar panels can still generate electricity in less-than-ideal conditions, like on cloudy or cold days.
