Solar-tracking control system, an indispensable support device that can effectively increase the power generation efficiency of solar panels . Due to the rotation of the earth, compared to a certain fixed-site solar photovoltaic power generation system, there are four seasons of spring, summer, autumn and winter. The lighting angle is changing from time to time, effectively ensuring that the solar panels can face the sun at all times and that the power generation efficiency will be optimal. Currently, the universal sun tracking control system in the world needs to calculate the angle of the sun at different times of each day of the year according to the latitude and longitude of the installation point, and store the sun position at each time of the year to PLC, SCM or computer. In software, that is, by calculating the position of the sun to achieve tracking. The computer data theory is used. It requires data and settings in the latitude and longitude regions of the earth. Once installed, it is inconvenient to move or attach or detach. Each time you move, you must reset the data and adjust each parameter. Principles, Circuits, Technology, Equipment Complex, non-professionals cannot operate casually. A certain solar photovoltaic power generation company in Hebei has exclusively developed a smart sun tracking system that is world-leading, low-cost, easy-to-use, does not require calculation of sun position data everywhere, no software, and can accurately track the sun anywhere on the mobile device. This system is the first solar space positioning tracker in China that does not use computer software at all. It has an international leading level and can be used without restrictions from geographical and external conditions. It can be used within the ambient temperature range of -50°C to 70°C; tracking accuracy can be achieved. Achieves ± 0.001° to maximize the sun tracking accuracy, achieve perfect tracking at the right time, and maximize the use of solar energy. Can be widely used in various types of equipment that need to use the sun tracking place, the automatic sun tracker is affordable, stable performance, reasonable structure, accurate tracking, convenient and easy to use. Install a solar power system equipped with a smart sun tracker on high-speed cars, trains, and emergency vehicles for communications, special military vehicles, warships, or ships. No matter where the system is heading, how to turn a head, or turn, the smart sun tracker It can ensure that the requirements of the equipment are tracked to the sun.
