It gives you on an interactive map of the sun trajectory everywhere on earth at any given time and any season.
Extremely useful to see the differences between location and seasons, or why and when on Groenland you have no sun or if the sun can rise more north than just east!
SunCalc is a web-based solar tracking application that calculates the sun’s position, sunlight phases, and shadow dynamics for any geographic location and date. It utilizes astronomical algorithms to provide precise data on sunrise, sunset, and twilight times, alongside the sun’s azimuth and altitude relative to the horizon. The interactive map interface allows users to simulate solar paths throughout the year, facilitating the visualization of seasonal variations in light duration and the calculation of shadow lengths for objects of specific heights.
Professionals in engineering and architecture apply these data sets to conduct shadow impact assessments and optimize building orientations for energy efficiency and natural lighting. In the renewable energy sector, the tool is used to determine the optimal placement and tilt of photovoltaic arrays to maximize solar irradiance capture.
