Abstract: A split-type power optimization module for solar module strings of a solar panel includes multiple power optimization module blocks. Each power optimization module block uniquely corresponds to one of multiple solar module strings on a solar panel and has a single-chip processor, a string connection port, and a power output port. The string connection port is connected to the single-chip processor and an adjacent solar module string. The power output port is connected in series to the power output port of an adjacent power optimization module block. Accordingly, each power optimization module block performs maximum power point tracking for the connected solar module string to lower the power loss of each solar module string and ensure string-level maximum power optimization.

Abstract: A split-type power optimization wiring box assembly for solar module strings of a solar panel includes a solar panel and multiple wiring boxes mounted on the solar panel. Each wiring box has a power optimization module block mounted therein. The solar panel has multiple solar module strings with each adjacent two of the multiple solar module strings connected through a corresponding wiring box. A power output terminal of each solar module string is connected to the power optimization module block inside a corresponding wiring box, such that the multiple solar module strings can be connected in series. The power optimization module block inside each wiring box performs Maximum Power Point Tracking on the connected solar module string for fulfilling power optimization on the basis of individual solar module string, thereby reducing the power loss of the solar module strings to achieve maximum power optimization of the solar panel.
