We found temperatures over a PV plant were regularly 3–4 °C warmer than wildlands at night, which is in direct contrast to other studies based on models that suggested that PV systems should. Large-scale solar power plants raise local temperatures, creating a solar heat island effect that, though much smaller, is similar to that created by urban or industrial areas, according to a. This study considers how large-scale application of solar panels will affect climate. Electricity generation leads to regional cooling but this is countered by the power’s use, affecting global. Reduced panel efficiency is a concern, addressed through solar panel design, radiative cooling techniques, and regular cleaning and maintenance. Understanding these heat effects, transfer mechanisms, and losses is crucial for optimizing solar energy systems. The heat dissipation of photovoltaic panels is achieved by increasing the number and height of fins to dissipate heat through heat conduction. On the other hand, it enhances heat transfer by increasing the heat exchange area between the heat sink and the surrounding environment and dissipates heat through convection and radiation between the . Can rooftop photovoltaic solar panels lower temperature in Kolkata?Here we show that, in Kolkata, city-wide installation of these rooftop photovoltaic solar panels could raise daytime temperatures by up to 1.5 °C and potentially lower nighttime temperatures by up to 0.6 °C. Do solar panels cause regional cooling?We find that solar panels alone induce regional cooling by converting incoming solar energy to electricity in comparison to the climate without solar panels. The conversion of this electricity to heat, primarily in urban areas, increases regional and global temperatures which compensate the cooling effect. Do solar power plants increase local temperatures?Sun et al. (2022) addressed the photovoltaic heat island effect, revealing that larger solar power plants increase local temperatures, challenging theoretical models and raising concerns for large-scale installations (Sun et al., 2022). Does phase change material affect heat dissipation of PV panels?Bria et al. [ 17] have studied the effect of phase change material, i.e., RT58, with a heat sink on the heat dissipation of PV panels by ANSYS Fluent using weather data from the city of Oujda in Eastern Morocco and compared it with the heat dissipation effect of two PCMs, i.e., RT42 and C22–C48. Can cooling solar PV panels improve power generation efficiency?It has been reported [ , , , ] that, when the temperature of crystalline silicon PV cells exceeds 25 °C, the power generation efficiency is reduced by 0.4–0.65% per 1 °C increase in the plate temperature. Therefore, cooling solar PV panels is an effective mean to improve the power generation efficiency of the panels. Can solar panels reduce air-temperature impact in urban areas?The potential for air-temperature impact from large-scale deployment of solar photovoltaic arrays in urban areas. Solar Energy 91, 358–367, doi: 10.1016/j.solener.2012.09.014 (2013). Masson, V., Bonhomme, M., Salagnac, J.-L., Briottet, X. & Lemonsu, A. Solar panels reduce both global warming and Urban Heat Isla
