pv magazine test September 2020 results

Share

The first chart to the right details the meteo station data (irradiance and ambient temperature) for September 2020. The daily temperature and irradiance data is missing for Sept. 26 due to a power cut. The average bifacial boost for September 2020 is 6.3%. Bifacial boost is defined as the extra energy yield of the bifacial products, compared to the average energy yield of all mono-facial mono PERC products. The chart to the bottom right shows the comparison between different PV module technologies for September 2020.

Bifacial modules are steadily performing above all the other technologies, with multicrystalline silicon PV having the lowest yield.

Notes on the energy yield measurements:

  • 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, including 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. 6648.jpgGeorge Touloupas

We are pleased to present the next batch of energy yield results from the outdoor test field in Xi’an, China. In this issue, we present the September results, along with analysis from George Toulouas, director of technology and quality at CEA.

Test cooperation

pv magazine test is a cooperative effort involving pv magazine, 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.
