Abstract: In the PV system with storage batteries, as a maximum power point tracking (MPPT) device is used to enhance battery charging, the enhancement must be greater than the internal loss of the device itself, or there will be no net gain at all. To evaluate the MPPT device benefits under different climate, the theoretical calculation models have been constructed. By simulation, a comparative study between two types of PV charge controllers with and without a MPPT device under different atmospheric conditions was presented. The comparison was made by means of the energy production obtained from the PV generator of each system. The climatic conditons of Beijing and Guangzhou in China have been regarded. From the results obtained it can be concluded that the effectiveness of the MPPT device in Guangzhou is not very obvious, however the MPPT device did greatly enhance the output in Beijing in the winter.
