WebMaking Our Irradiance Calculations 30 Times Faster. Because a project site can contain thousands of objects, and intersections with solar rays have to be calculated for every daylight hour of the year, the number of calculations that need to be computed can be significant. There are generally over 5,000 daylight hours for a given location. Solar irradiance is the power per unit area (surface power density) received from the Sun in the form of electromagnetic radiation in the wavelength range of the measuring instrument. Solar irradiance is measured in watts per square metre (W/m ) in SI units. Solar irradiance is often integrated over a given time period in order to report the radiant …
