The effect of vegetation on solar PV panel efficiency was tested in a commercial solar farm in the Negev Desert of Israel. Panel temperature in two test sites of 0.22 hectares each with different plant treatments was up to 3.5oC lower at midday compared to the panel temperature in an adjacent reference plot with bare loess soil. The temperature difference was not uniform, being greatest for the upper panels in a ground-mounted array (average reduction 2.2°C), and lowest for panels closest to the ground (1.0°C reduction).
