Farmers can benefit from solar energy in several ways—by leasing farmland for solar; installing a solar system on a house, barn, or other building; or through agrivoltaics. Agrivoltaics is defined as agriculture, such as crop production, livestock grazing, and pollinator habitat, located underneath. . One government grant program for solar panels on farms is called the Rural Energy for America Program (REAP). But first, what's this about “photovoltaic” initiatives? A photovoltaic system (PV system) is a more scientific word for the typical solar panel (or PV module) system we think of when we. . One approach to decarbonising agriculture involves integrating solar panels – or photovoltaics (PVs) – into fields of crops, greenhouses and livestock areas. Often known as agrivoltaics, this can help farmers reduce their carbon footprint while continuing to produce food. Solar energy offers a promising way to reduce long-term expenses, increase energy independence and even generate new income.
