Solar grazing with sheep is an almost perfect symbiosis: the solar panels provide shade for the grass growing under them, the grass evaporates moisture to cool the solar panels, increasing their efficiency on hot
Solar panels often known as arrays, are usually mounted 1.5- 2.5 metres above the ground, so the question is what best to grow beneath them. We have learned that contractors require a grass sward to be low in height and slow growing to
This is because many crops, including these grasses, actually grow better when protected from the sun, to an extent. And while the grass under your trampoline grows by itself, researchers in the field of solar photovoltaic
The most widely used type of photovoltaic panel is the "double-glass" type, consisting of two highly weatherproof transparent panes held together by plastic silicone. Between the two panes of glass are inserted silicon cells of
While the shepherds get paid to cut the grass on solar farms, the sheep use the grass and pastures under the solar panels for shade and grazing. Sheep-based agrivoltaics is found throughout Canada. A map
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.

This practice of growing crops in the protected shadows of solar panels is called .
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.
Most research has found that vegetables that benefit from partial shade such as lettuce, spinach, potatoes, beets, and carrots are the most efficient crops to grow in an agrivoltaic solar system. In experiments conducted in the Sonoran Desert, tomatoes, chard, kale, cabbage, and onions all performed well.
Only certain low-growing crops (such as lettuce, chard, beets, or spinach) can be cultivated under them, and they require manual cultivation and harvesting. For grazing areas, this solar panel solution is recommended only for smaller animals like sheep, due to its low ground clearance.
Barren terrain, traditionally prioritized for solar PV system installation, ranked fifth. “Researchers have successfully grown aloe vera, tomatoes, biogas maize, pasture grass, and lettuce in agrivoltaic experiments,” the researchers noted.
