4 November, 2021 In order to compare the power generation performance of bifacial PERC and monofacial modules installed using different methods, LONGi and the CGC conducted a one-year pilot project test in Togtoh county between December 2019 and December 2020. The results showed that, under conditions of saline soil and high temperature irradiation, the first-year power degradation of both modules was less than 2.0%. Compared with their monofacial equivalents, however, the bifacial modules produced a 10.0% higher level of power generation. The modules were able to deliver a significant energy yield gain when installed with a single-axis tracker (SAT).
