Study finds excessive row spacing has limited effect on improving PV system performance

Scientists in China have tested the influence of panel row spacing in increasing a PV system performance in a full-scale outdoor PV array experimental platform. They found that larger row spacing plays a limited role in improving thermal convection, observing that solar irradiance and wind speed are the key parameters for optimal PV system design.

Scientists in China have tested the influence of panel row spacing in increasing a PV system performance in a full-scale outdoor PV array experimental platform. They found that larger row spacing plays a limited role in improving thermal convection, observing that solar irradiance and wind speed are the key parameters for optimal PV system design.

A group of researchers led by the University of Science and Technology of China has investigated the influence of solar module row spacing on a PV system's temperature and efficiency and has found that excessive row spacing does not play a significant role in cooling the panels via thermal convection and increasing power yield.
