Growing vegetables next to photovoltaic solar panels is harmful

An Agrivoltaic farming project in Kenya is using solar panels held several metres off the ground, with gaps in between them. The shade from the panels protects vegetables from heat stress and water loss. This has resulted in rural farmers being able to grow a greater range of higher-value crops.

Research published in September finds that overall crop yields decrease when paired with solar panels and offers a way to standardize agrivoltaic regulations so we don’t give too much valuable .

This practice of growing crops in the protected shadows of solar panels is called agrivoltaic farming. And it is happening right here in Canada. Such agrivoltaic farming can help meet Canada’s food and energy needs and reduce its fossil fuel reliance and greenhouse gas emissions in the future.

This study observed growth responses of selected vegetable crops (okra, eggplant, green spinach, Chinese cabbage, Chinese kale, Brazilian spinach and pennywort) planted in the outskirt and row between the solar panels while under the panels, there were three distinct locations assessed: the highest elevated area, moderately inclined area, and .

Growing Crops Under Solar Panels? Now There’s a Bright Idea In the new scientific (and literal) field of agrivoltaics, researchers are showing how panels can increase yields and reduce water.

6 FAQs about [Growing vegetables next to photovoltaic solar panels is harmful]

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 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.

Can solar panels be installed without damaging crops?

French researchers have been investigating how solar panels can be installed without damaging the growth of crops for decades. Farms make up half of France’s land, by far the easiest host for solar-power projects compared with the urban regions, forests or protected natural areas that blanket the rest of the country.

Do solar panels increase crop yields?

A new synthesis of previously published studies finds that overall crop yields decline as the amount of land covered by solar panels increases. This ground cover ratio is a convenient, easily measured and reproducible metric that can be used to predict crop yields and better evaluate agrivoltaic systems.

Can Broccoli grow under photovoltaic panels?

Researchers in South Korea have been growing broccoli underneath photovoltaic panels. The panels are positioned 2-3 metres off the ground and sit at an angle of 30 degrees, providing shade and offering crops protection from the weather.

Can agrivoltaic plants grow in shade?

However, the plants grown through agrivoltaics are grown in partial shade, and “less light typically means less yield,” says Camporese. This effectively sets a limit on the density of solar panels and plantings on co-generation farms.
