Abstract This comment identifies and corrects two equation errors in the publication by Zonato et al. (2021, https://doi.org/10.1029/2021jd035002 ): An error is present in the paper in the formula for the radiation heat transfer between planar surfaces. A second error is identified where Zonato et al. (2021, https://doi.org/10.1029/2021jd035002 ) adjust the efficiency of solar panels for temperature erroneously using a minimum function, thus introducing a non‐existent discontinuity in the first derivative of efficiency as a function of temperature.
