The invention relates to a method and a device (10), for monitoring at least one unit part of a photovoltaic unit (20). According to the invention, determination of a temperature-compensated daily solar irradiated energy is carried out and a comparison of the determined temperature-compensated power ratio with a power ratio set value is carried out for the at least one plant part. A comparison of the power ratios determined on differing days or different times of year can by achieved for the photovoltaic unit (20). |
