Yes, this is likely no surprise to many, but seemingly it is a surprise for the few who thought this would have a negative impact.
“The findings suggest that the co-location of solar farming with sheep grazing is not negatively impacting wool production, even in the case of pre-existing high-quality standards,” Lightsource bp said, in a released statement. According to the farmer who owns the sheep, the quality of wool actually increased over this period.
Other studies have found that crops like maize, Swiss chard, and beans grow even better under partial shade provided by solar panels.
