Aiming at the problems that the photovoltaic power supplies of transmission lines monitoring devices are liable to be discontinuous and damaged, it is found that the power loss caused by surface dust deposition cannot be ignored. Improper configuration via empirical formula may result in power shortage and long‐term undercharging of the battery, finally shorten the equipment's life. What is more, artificial and field experiments were carried out to find the qualitative impact, and the attenuation coefficient related to dust deposition may ensure a more appropriate configuration. This research provides a reference for power supply design and helps to save the replacement.
