“…Solar energy resources are renewable energy, clean and pollution-free, the use of solar energy has been the focus of researchers [1][2][3], the intensity of photoelectric conversion efficiency is of great influence affecting the development of PV power generation, in order to make the PV panels strong illumination, scholars have taken a large number of studies on it, such as the biaxial solar automatic tracking system can be achieved on different sun angle tracking, which improved PV panels light efficiency [4,5], however, when it is fixed in the light intensity, the maximum photoelectric conversion efficiency is the most important parameter, in order to achieve a high conversion efficiency, the MPPT of PV is commonly used research method, now commonly methods are disturbance observation and incremental conductance [6,7].…”
