N2 - Degradation rates of photovoltaic (PV) modules were calculated by means of linear interpolation method only using outdoor data such as module temperature, solar irradiance, and current-voltage characteristics. This method could quantify not only degradation rates of output power of PV modules but also the others characteristic values such as short-circuit current, open-circuit voltage, and fill factor. As a result, it is revealed that crystalline silicon PV modules are degraded due to current reduction. In addition, relative errors of calculated degradation rate of each characteristic values are within 0.8% in average by comparing with the result of indoor measurement.
