Photovoltaics in the built environment: A critical review

However, since PV panels have very low thermal storage capacity, the surface temperature difference between the lower and upper surface of PV modules is typically small or negligible, and PV panel surface temperatures routinely exceed 70 °C, especially for very hot locations such as Phoenix, AZ [36], [48]. Thus, the assumption used in the Masson study is
