A method and system for monitoring the quality of photovoltaic cells is described, the method including for each cell: an excitation step, during which the cell to be monitored is subjected to excitation at a predetermined level of excitation; a step of acquiring at least one luminescence image of the cell to be monitored after excitation; and a step of processing the acquired image. The invention is characterized in that, for each cell, there is provided a preliminary step for determining an excitation level adjusted to the cell, the respective adjusted excitation levels of the different cells to be monitored being adapted such that the luminescence intensities of the signals emitted by the different cells are equal at a given reference luminescence intensity.
