Understanding the Relationship Between Solar Panels and Soil Health

Scientists have discovered that the best locations for installing large solar panels share similarities with areas traditionally designated for cropland. Utilizing solar panels on farms offers a sustainable and cost-effective solution for generating clean energy, especially in remote locations where access to conventional electricity is limited.

Implementing solar energy on farms not only contributes to environmental sustainability but also provides farmers with an opportunity to diversify their income and reduce operational expenses. Solar panels can effectively power equipment, well pumps, and various devices, offering a reliable alternative in areas prone to power outages.

One notable benefit is the potential to decrease the need for irrigation during power disruptions. However, concerns may arise about the impact of extensive solar arrays on soil health. Let’s explore the latest research findings on this matter.

The Impact of Large Array Constructions on Soil Health

The US Department of Energy has created a guide to assist farmers in making informed decisions about integrating solar panels into their operations. Their research indicates that the addition of solar panels may have certain effects on soil health.

Studies reveal that trace amounts of chemicals used in photovoltaic panels have minimal to no impact on soil health. However, a European study suggests that large solar panels can influence soil chemical and physical characteristics. The soil underneath these panels tends to be up to 10 degrees warmer compared to uncovered soil, resulting in lower CO2 levels. This is particularly beneficial for soil health, especially in regions with high temperatures.

Solar Panels and Water Distribution

Considerable research has focused on the interaction between photovoltaic (PV) arrays and soil. Multiple studies have consistently shown that the soil beneath ground-mounted solar panels retains more moisture. Additionally, the plants growing in these areas create a cooling effect, enhancing the efficiency of the solar panels.

The impact of solar panels on soil moisture has the potential to contribute to increased energy independence, decreased water consumption, and improved crop yields. It’s also important to examine the runoff from the surfaces of the panels. Properly channeled, this rainwater can be utilized for farm irrigation, reducing the strain on water resources.

Integrating Solar Panels with Grazing for Improved Soil Health

Researchers have explored the possibility of utilizing the land beneath solar panels for small livestock grazing. Sheep, in particular, thrive in these conditions. The presence of pollinator-friendly plants under the panel arrays has been shown to enhance crop yields. An analysis revealed that soils in solar grazing sites exhibited higher levels of nitrogen and carbon without compaction compared to similar non-grazing areas.
