Scientists have found that the best places to build large solar arrays have the same characteristics as areas traditionally used as crops.
Solar panels can provide clean and affordable energy for your farm, while making it easier to manage remote areas where traditional power lines are impossible.
Adding solar generation can diversify income streams and reduce overall operating costs for many farmers.
Additionally, solar panels are used for various purposes such as running equipment and powering well pumps.
For example, solar panels help reduce concerns about watering crops during power outages.
However, like many farmers, you may be concerned about the potential impact of large solar arrays on soil health.
Let’s see what current research has to say on the topic.
Effects of large-scale construction on soil health
The US Department of Energy offers guidance to help farmers make informed decisions about solar panels.
According to their research, the addition of solar panels may have some effect.
Evidence shows that small amounts of chemicals from photovoltaic panels have little or no effect on soil health.
A European study has shown that large solar masses affect the physical and chemical characteristics of soil.
In addition, the soil under the panels was up to 10 degrees cooler than the soil without the cover, producing lower levels of CO2.
Given the rising temperatures in many prime agricultural regions, this is positive for soil health.
The effect of solar panels on water distribution
Considerable research has investigated the interaction between PV arrays and soil health.
Many studies confirm that the soil under the in-ground panels holds more moisture than the surrounding soil.
Also, the plants growing there have a cooling effect, which helps the solar panels work more efficiently.
The effect of solar panels on soil moisture can help increase energy independence and reduce water consumption while increasing yields.
Another area to explore is the redirection of runoff from panel surfaces.
If properly channeled, this rainwater can be used for irrigation, further reducing demand on your farm.
Integrating pasture with solar panels for soil improvement
Researchers have studied land under solar panels for use by small grazing livestock.
Sheep, in particular, thrive in these conditions.
In addition to improving soil quality, pollinator-friendly vegetation under panel arrays helps increase yields.
According to one analysis of solar-grazed sites, soil under PV panels had higher levels of non-fixed nitrogen and carbon compared to similar, non-grazed sites.
