Solar power generation and cattle farms

Is grazing cattle under solar panels a good idea?

There is growing interest in grazing cattle underneath solar panels. This year, the Energy Department launched the Large Animal and Solar System Operations (LASSO) Prize, providing millions of dollars for research around solar development and cattle grazing.

Can solar energy be used for livestock farming?

Solar electrical energy could be co-generated with livestock farming, in addition to co-producing electricity and agricultural crops. According to Lytle et al. (2020), who proposed an agrivoltaic system design idea based on feeding rabbits, this system could increase overall income by 2.5 %–24 %, as each rabbit has a high value per unit weight.

Can solar energy be generated hand in hand with grazing livestock?

According to a research trial launched in 2010, solar energy can be generated while grazing livestock or growing crops. University of Massachusetts (UM) agronomist Stephen Herbert explains, "The purpose of our work has been to see if we could generate solar energy while keeping the land in agricultural production.

Can on-farm solar power help cattle graze?

This investment in on-site solar energy has inspired studies of the benefits of on-farm solar beyond power generation, including providing cattle with a cool resting place as they graze, and research evaluating the cost-effectiveness of such systems.

Can a ground-mounted solar system provide shade for dairy cows?

The cows are split almost evenly between a conventional and a certified organic grazing herd. There is no research that has investigated the use of a ground-mounted solar system to provide shade for dairy cows and to determine the effects on dairy cows.

Do cows regrowth based on the Solar System?

The solar system was permanent in the pasture; therefore, cows were on the study pasture based on grass growth and rotation of pastures within the dairy herd. The study allowed approximately 30 d of regrowth to occur on pasture before cows returned to the grazing pasture with the solar system.
