Two states (MN and MD) have already developed pollinator-friendly solar certifications to promote planting of pollinator habitat that can benefit local farms.In addition, solar can provide several benefits to agricultural land managers that may offset capital costs of installing solar: Herbicide is currently sprayed around some solar modules to prevent weed growth. Care should be taken to not spray modules themselves, but if it occurs the modules can be washed off with water as they are made of glass and steel or aluminum and have been designed to withstand outdoor conditions. Solar can offset power required for pumping and provide power to remote irrigation systems, requiring no grid connection.
The frequency of most inverters is 50-60 Hz, the same as AC electricity in your home or commercial building, which is within the range audible to humans and well below the higher frequencies used to repel animals.
Sound is generally not audible at the edge of the fenced boundary, but if audible, the sound is similar in volume to background noises and dissipates to inaudible 50 – 150 feet from the edge of the boundary.
Most solar panels have a glass front that protects the PV cell and an aluminum or steel frame.
Research shows that “leaching of trace metals from modules is unlikely to present a significant risk due to the sealed nature of the installed cells.”Some solar modules use cadmium telluride (Cd Te).
One study found that air temperature, humidity, and crop temperature under modules was similar to conditions of full sun.
This study found that soil temperatures at night under the modules was less than that of soil temperatures in full sun all day.
A growing number of farms and agricultural businesses are looking to solar to power their daily operations.
Thanks in part to the Solar Energy Technologies Office's investments, the cost of going solar has declined, enabling more installations across the country.
Cadmium compounds are toxic, but studies show that such compounds cannot be emitted from Cd Te modules during normal operation or even during fires.
Industrial incineration temperatures, which are much higher than grassfires, are required to release the compounds from the modules.
