The KNMI provides a daily solar irradiation forecast. The sun's power is a measure for the amount of ultraviolet radiation (UV) in sunlight that reaches the earth. The higher the sun is in the sky, the more solar radiation enters the atmosphere. Part of that radiation is invisible ultraviolet light (UV). It gives you a tan, but too much UV leads to sunburn and can eventually cause skin problems. The total amount of UV on the ground at noon is called solar power, internationally also known as the UV Index. The data is published in two different formats: txt and xml.
