pv magazine test: March 2024 results



Due to system maintenance, we removed the March 1, 2024 data, meaning only 30 days of results were collected.

The first chart above shows the meteo station data (irradiance and ambient temperature) for March 2024. The average bifacial boost was 7.0% for the month. Bifacial boost is defined as the relative advantage of the average specific energy yield of all bifacial products compared to the average specific energy yield of all monofacial passivated emitter and rear cell (PERC) products.

The bifacial boost fell from the February 2024 peak of 10.35%, to 7%, which was due to the high reflectance of the patches of snow that were lying on the ground. This will continue to rise, peaking in the summer months when the sun reaches it maximum elevation and there is less shading of the ground.

Energy yield measurements

  • The energy yield comparison among various technologies, including bifacial boost, is analyzed using products installed after the beginning of 2019.
  • The energy yield is given in Wh/Wp and calculated by dividing the energy produced by the module by the maximum power point (Pmax) at standard testing conditions (STC) of the module. This Pmax is the maximum STC power after a process of stabilization.
  • The results are grouped in categories, per solar module type.
  • The bifacial boost depends on a number of parameters: the bifaciality factor, the installation geometry, the albedo of the ground, 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, Clean Energy Associates, Gsolar, and Hoymiles. All testing procedures are carried out at Gsolar’s test laboratory in Xi’an, China. The CEA supervises these tests and designed both the indoor and outdoor testing procedures.
