TaiyangNews Top Solar Modules report analyzed the top 3 solar module efficiencies over the last 2 years. During 2024, the top efficiency improved only by 0.2%, but it is a significant 1.4% absolute when looking at the last 2 years put together. At the beginning of 2024, IBC held the top 2 ranks while HJT was 3rd. Starting in May, the top 3 efficiency spots have become an exclusive IBC forte. All the 3 ranks saw a revision each during this period. Having held the top rank since the start of the year with an efficiency of 24%, AIKO beat its own record by commercializing a 24.2% efficiency module in May (see Efficiency Trends And Technology Shifts In TOP SOLAR MODULES).LONGi’s HPBC module, which held the 2nd spot with an efficiency of23.2%, remained unchanged throughout the year. However, Maxeon commercialized a module based on IBC technology with an efficiency of 24.1%. With this module, Maxeon claimed the 2nd position while pushing LONGi’s product to 3rd and Huasun’s HJT module out of the top 3. Thus, at the end of 2024, the TOP SOLAR MODULES list features 2 commercial modules with efficiencies above the 24% efficiency benchmark.In contrast, the developments in 2023 were more phenomenal. At the beginning of the year, IBC modules from LONGi and Maxeon shared the top spot with the same efficiency figure of 22.8%, with JinkoSolar’s 22.65% efficiency TOPCon module in 3rd. There was no change in the top 3 ranks in February, but the next change was a rather groundbreaking one that took place in March. China’s prime cell maker AIKO ventured into the module supply business with the commercialization of a 23.6% efficiency module – the highest commercial module efficiency at the time. With AIKO’s ABC module entering the list in March, the top 3 ranks became exclusive to IBC modules. While AIKO maintained its lead, March and April saw LONGi and Maxeon share the 2nd position. However, the rankings changed in May as LONGi upgraded the efficiency of its Hi-MO 6 module series to 23.2%, making the 2nd position its own. June marked another significant development as AIKO created history by attaining a landmark efficiency of 24% for commercial modules. The next change in the top 3 ranks took place in September, when Huasun breached the IBC fortress with its HJT module with an efficiency of 23.02%, ranking 3rd on the list. The top 3 ranks remained so for the rest of 2023 (see Tracking Efficiency Improvements In Solar Modules).
