pv magazine test: March 2022 results


The first chart to the right shows the meteo-station data (irradiance and ambient temperature) for March 2022. The average bifacial boost for the testing period is 7.0%. To clarify, bifacial boost is defined as the extra energy yield of the bifacial products compared to the average energy yield of all monofacial mono PERC products.

The chart to the bottom right compares different PV module technologies for March 2022. Bifacial modules are performing better than monofacial modules, and bifacial TOPCon leads over bifacial PERC. Please note that our test field only has one sample from Jolywood in the “n-TOPCon” category and one sample from Znshine in the “multi” category.

Notes on energy yield

  • The energy yield comparison among various technologies, including bifacial boost, will be analyzed using products installed after the beginning of 2019.
  • The energy yield is given in Wh/Wp and is calculated by dividing the energy produced by the module by the Pmax at STC of the module. This Pmax is the maximum STC power after a process of stabilization.
  • The results are grouped in categories, per module type.
  • The bifacial boost depends on many parameters: the bifaciality factor, the installation geometry, the albedo of the ground, and the sun angle and diffuse irradiance. The ground in this case is gray gravel.

Test cooperation

pv magazine test is a cooperative effort involving pv magazine, APsystems, CEA and Gsolar. All testing procedures are carried out at Gsolar’s test laboratory in Xi’an, China. CEA supervises these tests and designed both the indoor and outdoor testing procedures.
