No grass grows under photovoltaic panels

How do you keep grass under solar panels from growing too high?

Solar power plants provide many benefits but at least one perpetual challenge: How do you keep grass under the panels from growing too high? Mowers with traditional blades can damage equipment. Hand-held weed-whackers are a labor-intensive solution. Even the sheep tried at one small site behaved unreliably.

Where does pasture grass grow under solar panels?

A common C 3 pasture grass (smooth brome, Bromus inermis) grows underneath and between the solar panels. The model was parameterized with easily measurable plant traits and driven by a combination of measured and reanalysis-derived weather data. Conceptually, we partitioned the AV system into 4 locations 20 (Fig. 1).

Should agrivoltaic planners put solar over a farm?

Or farm first, and put solar over it?” If farming is the main priority, she says, then the solar panels may need to be spaced farther apart and possibly be raised higher. Such changes could potentially limit how much electricity those farm fields generate. And agrivoltaic planners may need to treat the soil, Macknick says.

Are solar panels good for agrivoltaic crops?

Raspberries grown under solar panels in the Netherlands. Image courtesy of GroenLeven. Many agrivoltaic trials have reported promising results. For example, a project in southern France found that grapes grown under solar panels needed less irrigation and were of higher quality.

Can we grow crops under solar panels instead of trees?

Traditionally, agricultural and agroforestry systems used multilayered plantings by, for example, cultivating shade-tolerant crops such as coffee under bananas. Now, with growing demand for clean energy but a paucity of empty land, researchers are exploring how to grow crops under raised solar panels (photovoltaics) instead of trees.

Do solar photovoltaic panels promote vegetation recovery?

Liu, Y. et al. Solar photovoltaic panels significantly promote vegetation recovery by modifying the soil surface microhabitats in an arid sandy ecosystem. Land Degrad. Dev. 30, 2177–2186 (2019).
