Report: Researchers Shed Light on Mysterious, Higher Energy Yields in Vertical PV Systems

A group of researchers at the Netherlands Organisation for Applied Scientific Research (TNO) has conducted a series of tests and simulations to understand why vertical PV systems tend to provide unexpected yield gains compared to horizontal arrays and have found that vertical installations have much lower operating temperatures.

“Although better than expected performance for vertical installation of bifacial PV has been reported at conferences and workshops, we haven’t seen any publications that show that this is accompanied with a much lower operating temperature than you would expect for free-standing fixed tilt PV with the same total irradiance,” the research’s corresponding author, Bas B. Van Aken, told pv magazine.
