JinkoSolar, a globally PV module manufacturer, has conducted a field test in Kagoshima, Japan. The purpose was to compare the low-light performance of N-type TOPCon and N-type BC modules. From June 2 to June 30, 2025, both module types with identical dimensions but different glass configurations were tested. They were installed on fixed mounts with data collected every minute using the CR1000X system. TOPCon modules recorded an energy yield of 119.61 kWh/kW during the test period. In comparison, the BC modules yielded 110.47 kWh/kW, showing an 8.27% gain for TOPCon. Yield differences were more prominent during early morning and late afternoon hours. The peak performance gap reached 10.79% under irradiance below 400 W/m². The field location in Kagoshima was selected for its frequent low-light conditions, ensuring consistent evaluation of weak-light response.Recently,JinkoSolar reported supply progress on Somalia’s 3.9 MW hybrid healthcare project.
