This effect of heating the air is greater in summer. The nighttime air temperature at a height of 2 m during the four seasons at the solar farm is higher than that in the region without PV arrays, since the solar panels exhibit heat preservation effect near the ground.
For instance, Nemet compared the reduction of the replacement of fossil fuels with PV power generation, in particular the increase in radiative forcing resulting from the increase in the albedo of PV panels, and found a reduced radiative forcing of roughly a factor of 30.
PV panels convert most of the incident solar radiation into heat and can alter the air-flow and temperature profiles near the panels. Such changes, may subsequently affect the thermal environment of near-by populations of humans and other species.
Solar panels absorb solar energy to produce energy usable in buildings, either directly in the form of heat (typically to warm water) or as electricity. However, in doing so, they modify the energy balance of the urban surface in contact with the atmosphere, and so possibly influence the urban micro-climate.
And as a result, you end up having two hot surfaces, the top surface of the panels and the underside surface of the panels. And so, as air flows over these panels, it readily picks up that heat essentially twice as effectively as it would if you had the same temperature on a building surface or a ground surface.
The solar panels also slightly modify the energy consumption of the buildings. During winter, the solar panels could induce a decrease of the energy consumption due to more infra-red energy reaching the roof, or increase it by reducing the amount of solar radiation received or by their effect on the UHI.
