Grass Under Solar Panels

Beneath solar panels the seeds of opportunity sprout.

Grass under solar panels. Low impact development of solar installations could be win win win for food water and renewable energy. Weed or vegetation management is particularly important for ground mounted solar systems. The plants also had more nutritional value. Higgins and co author elnaz hassanpour adeh had previously published research showing that solar panels increase agricultural production on dry unirrigated farmland.

Only their bright yellow hard hats are clearly visible above the tall nearly overgrown prarie grasses which are growing exactly as expected.

On a humid overcast day in central minnesota a dozen researchers crouch in the grass between rows of photovoltaic pv solar panels. The bare ground beneath solar panels near boulder has been planted with grasses and mulched in a test to soften the appearance restore native habitat and protect soil from erosion. Solar shading decreased production 5 3 percent to 19 percent. Grazing sheep or cattle on grass grown under solar panels.

Tall weeds growing around the installation can create shading which can negatively impact system production. They found that the grasses growing in shaded areas under the solar panels were 328 more water efficient and maintained higher soil moisture throughout the heat of summer.
