The error between the apparent series/shunt resistances of solar cells estimated by the current–voltage slope at the open‐/short‐circuit condition and the true series/shunt resistances is calculated by the exact analytical expressions of the one‐diode equivalent circuit model for the solar cell. In order to avoid the difficulty in computation in known expressions, the exact analytical expressions based on the g‐function proposed by Roberts are derived and employed. Significant deviation is found between the apparent and the true series/shunt resistances. © 2018 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
