pv magazine test: February 2022 results


The first chart to the right shows the meteo-station data (irradiance and ambient temperature) for February 2022. The average bifacial boost for this period was 5.6%. 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 shows the comparison between different PV module technologies for February 2022. Bifacial modules are steadily performing above all the other technologies, with multicrystalline modules having the lowest yield.

Notes on the 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 into 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.
