12 April, 2024 Situated within the national photovoltaic PV product outdoor testing base in Qionghai City, Hainan Province, our year-long field test provides compelling evidence of JA Solar’s innovative n-type bifacial PV modules thriving in demanding climates. Hainan, known for its tropical monsoon climate, with an average annual temperature of approximately 24°C and yearly precipitation reaching around 2,100 millimeters, the region poses significant challenges for solar technology. Pease refer to Figure 1 illustrating the field testing project.
