Is it okay to plant soybeans under photovoltaic panels

“Our work confirmed that soybean is shade tolerant and can be grown in combination with solar power generation,” researcher Eleonora Potenza told pv magazine.

(1) A semitransparent photovoltaic panel could maintain soybean yield without reduction and maintain crude fat content of 97.20 %, soluble sugar content of 94.93 % and starch content of 98.73 % compared to that without photovoltaic panels; (2) The plant height and stem thickness phenotypes of the semitransparent photovoltaic modules were not .

Cornell University researchers have discovered that soybeans planted beneath 3.9-meter-high solar modules can positively affect panel temperatures and the microclimates of farms.

Solar panels mounted 4 meters above a soybean crop were connected to temperature reductions of up to 10 degrees Celsius, the study found, compared to solar panels mounted half a meter above.

The engineers showed that solar panels mounted over vegetation reveal surface temperature drops compared to those arrays built over bare ground. Solar panels were mounted 4 meters above a soybean crop and the solar modules showed temperature reductions by up to 10 degrees Celsius, compared with solar panels mounted a half-meter above bare soil.

6 FAQs about [Is it okay to plant soybeans under photovoltaic panels ]

Can we grow crops under solar panels instead of trees?

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.

Are solar panels good for agrivoltaic crops?

Raspberries grown under solar panels in the Netherlands. Image courtesy of GroenLeven. Many agrivoltaic trials have reported promising results. For example, a project in southern France found that grapes grown under solar panels needed less irrigation and were of higher quality.

Can you grow corn under solar panels?

Height, too, is an issue: Corn and wheat would need taller panels, while shrubby soybeans would be fine with a more squat variety. Thanks to those gaps, crops grown under solar panels aren’t bathed in darkness. But, generally speaking, the light is more diffuse, meaning it’s bouncing off of surfaces before striking the plants.

Are solar panels a good predictor of crop yields?

The study also showed that the ratio of solar panels to land area was a good predictor of crop yields. Even when just a fifth of the ground was covered by solar panels, losses were significant. This also takes into account that some land is taken up by posts, cables and other hardware so can no longer be planted.

Do solar panels reduce crop yields?

Some countries — notably France, Germany, Italy and Japan — already have regulations that limit how much solar installations on agricultural land are allowed to cut into crop yields. The relationship between the number of solar panels and the yield gives an improved scientific basis for those types of regulations.

Can organic solar PV improve tomato production?

It was evaluated theoretically that the use of organic solar PV can improve the production of tomatoes by 46 % more than standard Si PV greenhouses. For this analysis, ground-measured weather data was collected for the location of Geraldton in Australia while the crop was a tomato. Land use and land cover is changing significantly in Africa .
