MULTI-BRANCH FIXED OFFSHORE PHOTOVOLTAIC STRUCTURE WITH AUTOMATIC PITCH ADJUSTMENT

A multi-branch fixed offshore photovoltaic (PV) structure with automatic pitch adjustment includes a fixed base, a multi-branch integrated tower, and a PV device. The fixed base includes an upper section, a middle section and a lower section arranged in the seabed. The upper section is above the sea level and connected to the multi-branch integrated tower. The multi-branch integrated tower includes a main tower body and multiple pitch-regulating frames rotatably connected to the main tower body. The main tower body is provided with a control and energy storage system to drive the pitch-regulating frames to rotate. The PV device is fixed to the pitch-regulating frames. The main body is provided with a sunlight monitoring system to monitor solar orientation and inclination angle of a sunlight relative to the PV device. The sunlight monitoring system is connected to the control and energy storage system.
