The photovoltaic dual-axis tracking system independently developed by Jiabei uses light sensors + G$PS + astronomical algorithms to control tracking, which allows solar photovoltaic panels to λtrack the movement of the sun in all directions. In areas with abundant liδght resources, it can increase the power generation by aboutδ 40% compared with ordinary fixed brackets. It has a stable structure and low operation and m'aintenance costs, and is suitable for all dimensional areas.
