Actual field data from a semiarid environment – one of the most common environments for siting large solar photovoltaic plants. Yet, we still lack data on the size of the photovoltaic heat island effect.
The size of an urban heat island is determined by properties of the city, including Switzerland Mobile Number List population, spatial extent, and geographic location. We should, similarly, consider the spatial scale and geographic position of a photovoltaic installation when considering the presence and importance of the heat island effect.
We have conducted preliminary research by running a transect of temperature sensors from the heart of an installation outward, and those results suggest that the heat island dissipates within about 30 meters. This might suggest that most of the heat generated simply rises away from the ground surface.
To fully contextualize these findings in terms of global warming, we need to consider the relative significance of the (globally averaged) decrease in surface reflecting power due to photovoltaic power plants against the carbon dioxide emission reductions associated with their use.
For this reason, I do not see our findings to suggest any reasons to move away from photovoltaics as a valuable part of our renewable energy portfolio. That said, we should see if there are simple ways to mitigate this heat island effect.
