In the new scientific (and literal) field of agrivoltaics, researchers are showing how panels can increase yields and reduce water use on a warming planet.

Impacts of colocation of agriculture and solar PV panels (agrivoltaic) over traditional (control) installations on irrigation resources, as indicated by soil moisture. a, b,
It is unlikely that growing grains or dry beans under photovoltaic arrays will ever be cost-effective. So, what is different and distinctive about the shaded growing spaces under photovoltaic
A critical issue in the development of AV is the selection of crops that can grow profitably under the micrometeorological conditions generated by AV systems. and two agrivoltaic systems
According to the paper, growing chiltepin pepper, jalapeno and cherry tomato in dryland areas of the U.S. under the shade of PV modules is not only possible, but can lead to a better harvest.
Agri-PV (PV stands for photovoltaic, another term for solar panels) combines agriculture with solar energy production. In the Netherlands, only a handful of growers have solar panels above their
The electricity these generate powers a few hundred nearby homes. Under and around these panels are sprawling fields of the low, dense blueberry bushes. Lily Calderwood knows more about wild blueberries than
Under PV panels, species with extreme values of the monitored soil criteria have a higher representation. These species can tolerate salinity, deficiency, or excess nitrogen and
Research indicates that growing crops beneath photovoltaic displays can actually yield a distinct set of agricultural and environmental benefits. Thanks to the shade provided by the panels, for example, the soil can retain more water, meaning it needs less irrigation.
Traditionally, agricultural and agroforestry systems used multilayered plantings by, for example, cultivating shade-tolerant crops such as coffee under bananas. Now, with growing demand for clean energy but a paucity of empty land, researchers are exploring how to grow crops under raised solar panels (photovoltaics) instead of trees.

Solar panel installations may not be compatible with the machinery used to harvest many crops, and boosting the panels higher off the ground costs extra. But there are configurations for certain crops in certain areas that can make a lot of sense.
Studies from all over the world have shown crop yields increase when the crops are partially shaded with solar panels. These yield increases are possible because of the microclimate created underneath the solar panels that conserves water and protects plants from excess sun, wind, hail and soil erosion.
And while the grass under your trampoline grows by itself, researchers like me in the field of solar photovoltaic technology — made up of solar cells that convert sunlight directly into electricity — have been working on shading large crop lands with solar panels — on purpose.
