Test Results:

From June 1 to June 30, 2025, the performance of the two types of modules was comprehensively tested. Results showed that the normalized energy yield of TOPCon modules reached 119.61 kWh/kW over the 30 days, compared to 110.47kWh/kW for N-type BC modules. On average, the long-term energy yield gain per watt for TOPCon modules was 8.27%.

Dive deep into daily change, it reveals that the earlier in the morning and the later in the afternoon when light intensity is the lowest level in a day, the yield gain over n-type BC is more obvious,  highest gain period occurring in low-light irradiation (0-400W/㎡)  of 10.79%
