Evaluating Production of Five Leafy Greens under Opaque and Thin Film Semitransparent Photovoltaic Arrays

Urban Farm DB summary

A two-year study at two locations evaluated five leafy greens (arugula, kale, lettuce, spinach, Swiss chard) under opaque and 40% semitransparent photovoltaic (PV) modules and full sun. Four of the five crops, excluding spinach, showed higher fresh and dry weight under 40% semitransparent modules compared to other treatments and full sun. While most leafy greens under PV modules had lower stomatal conductance, lettuce and Swiss chard under semitransparent modules showed higher stomatal conductance.
