Solar energy, when accidently focused, can cause wildfires and melt plastics. Solar irradiance concentration analysis can help to optimize wanted concentration or avoid unwanted concentration. This article provides a workflow on how to perform solar irradiance concentration analysis using light simulation software. As an example, an automotive headlight will be used. One analysis approach is to filter the object surface sensors for the maximum irradiance value of a given sun position. All maximum irradiance values can then be mapped in relation to the horizontal and vertical sun position, creating a solar irradiance map. If the maximum irradiance value of this map is below a given threshold, then the analyzed product is safe for sun exposure.
