Reasonable outdoor operation test needs to enable the solar panel to output electric energy in the form of maximum power outdoors, and simultaneously needs to record the current and voltage at the maximum power in real time. According to the recorded current and voltage, the output power of the photovoltaic panel can be obtained, and the photovoltaic performance change of the panel can be observed and analyzed. At present, the photovoltaic inverter can realize outdoor operation test on the solar cell of a component level, and the photovoltaic inverter requires the output power of a tested battery plate to be more than 100W and the starting voltage to be more than 20V. The problem is that in order to shorten the development period and save materials, most colleges and research institutions prepared in laboratories are miniature solar cells, the output power of the cells is less than 5W, and the open-circuit voltage is also less than 20V. At this time, the photovoltaic inverter cannot meet the outdoor operation test requirements of the solar cells. There are portable photovoltaic outdoor test systems which can monitor the I-V curve of a solar cell and calculate the maximum power point of the cell, but these systems cannot keep the tested cell at the maximum power point for electric power output, as in patents CN103293460, CN102944828A and CN 208479576U. There are also photovoltaic systems that can track or measure the maximum power point of the solar cell, but cannot record the voltage and current at the maximum power point in real time, and cannot realize the calculation of the output power of the cell and the analysis of the variation of the photovoltaic performance, such as patents CN103227483B and CN 103607021A.
Patent CN205430174U provides a real-time measurement system for voltage and current of solar panel, but it can only measure and record voltage and current of solar cell, and cannot perform maximum power point tracking on the cell.
