A solar generator apparatus (1), which has suspending supports and is mounted on a fixed structure, includes a solar generator module (10), a middle column (20), three side columns (30,40,50) and three elastic members (60,70,80). The solar generator module (10) converts light into electricity. The middle column (20) for rotatably supporting the solar generator module (10) has a first end mounted on the fixed structure, and a second end pivotally connected to a middle portion of a bottom of the solar generator module. First ends of the three side columns are mounted on the fixed structure. The three elastic members (60,70,80) for assisting in supporting the solar generator module (10) respectively connect second ends of the three side columns to the solar generator module (10).
