The invention belongs to the technical field of solar energy, and discloses a sun position real-time measurement method, system and device, and the method comprises the steps: obtaining initial daylighting panel attitude data, the initial daylighting panel attitude data comprises an initial triaxial acceleration G1 and an initial triaxial geomagnetic field intensity M1; acquiring the attitude data of the daylighting panel when the daylighting panel is vertical to the incident light, wherein the attitude data of the daylighting panel when the daylighting panel is vertical to the incident light comprises three-axis acceleration G2 in the vertical process and three-axis geomagnetic field intensity M2 in the vertical process; the attitude data is used for acquiring the course angle and pitch angle of the daylighting panel, acquiring the azimuth angle and elevation angle of the sun, and acquiring the position of the sun according to the azimuth angle and elevation angle of the sun. According to the sun position re
