A new report is worried about the shade of PV panels cooling the
ground below and points toward shade-loving plants being required.

According to the paper published in the journal Environmental Research
Letters, the microclimate around the bank of photovoltaic panels
studied near Swindon in the UK changed by as much as 5 degrees
Celsius, depending on the season. While this might seem like an
obvious side effect of creating a big field of artificial shade, the
researchers from Lancaster University and the Centre for Ecology and
Hydrology are concerned about the impact on the plants and soil
underneath all those solar panels.
