Aiming at the problem of low conversion efficiency in traditional systems, a photoelectric conversion efficiency optimization system for marine photovoltaic panels is proposed. According to the hardware block diagram of the system, a photovoltaic panel based on the photovoltaic effect principle is designed. The larger load generated by the main winding of the electronic transformer is converted to a smaller load. Based on the load, the operation parameters of the electrical equipment are reflected in real time. A full duplex flow control and half duplex voltage controlled converter is designed with the access to the optical fiber special line. According to the software design process, the influence coefficient of the solar radiation is obtained. This coefficient is used to calculate the imbalance of the photovoltaic panel and the energy after the solar photovoltaic panel is reflected, thus the design of the photoelectric conversion efficiency optimization system is realized. The experimental results show that the maximum conversion efficiency of the system can reach 86%, which can effectively help ship power system optimization.
