Abstract :
On the base of photovoltaic mathematical model, the output characteristics of photovoltaic module in centralized MPPT and distributed MPPT are analyzed. In the actual photovoltaic module with distributed MPPT, output characteristics and efficiency are measured in normal and shadow background. The results is wide input and output voltage range, system of limited single module power output does not affect other module outputs, maximize energy collection and output, making the utilization projects photovoltaic battery more feasible.
