This review has addressed the question of what factors contribute to the conflicting effects of PV panels on urban temperature and pointed out future research directions. Results highlight variations in urban configurations, simulation settings, sensor placements, and measurement protocols, leading to inconsistent findings.
As summer temperatures rise throughout the day, solar panels store this heat for a longer time. When the PV module begins to be exposed to sunlight (the same at the end of the day), a clear difference is produced between the measured (using thermocouple sensor) and estimated temperature.
In this work data from outdoor measurements, acquired over the course of up to three years on commercially available solar panels, is used to determine the temperature coefficients and compare.
