"As for the crops, there were some significant differences. As the chiltepin peppers are shade-adapted, they were considerably happier with some solar panels overhead. Growth was calculated in terms of CO2 uptake, and this was 33% higher in the combined plot. The water-use efficiency of the plants didn’t change, so they also used more soil moisture as they grew. The mass of peppers they produced, however, tripled under the solar panels."
