The efficiency band between 21.5% to 22% initially had minimal representation, dominated solely by Meyer Burger's HJT module in early 2022
By September 2022, Trina Solar and Qcells joined with TOPCon modules at 21.9% and 22% efficiency, respectively
Jinergy entered in September 2023, improving its HJT module efficiency from 21.68% to 21.85%.
For easier analysis, in TaiyangNews TOP Solar Module Analysis report we have categorized efficiency into four bands. This band, representing modules with efficiencies from 21.7% to 22%, is the 3rd band. This efficiency band has the least representation. In January 2022, the only product present in this efficiency range was the HJT module from Meyer Burger. Then, in February, SPIC's IBC module was also added to our listing, with 22% efficiency. However, the very next month, the company improved its efficiency to 22.1%, thus jumping to the next class and leaving Meyer Burger all alone in this efficiency range.
It continued until September 2022, when Trina Solar launched a TOPCon module with 21.9% efficiency, which remained the same until December2022. In the same month, Qcells' TOPCon module reappeared with a lower efficiency of 22%, increasing the product count in the month to 3. However, the TOPCon products from Trina and Qcells improved their efficiency in the months of March and April 2023, respectively, again leaving Meyer Burger as the lone contender in this efficiency class. This continued until August (see Insights On High-Efficiency Solar Modules).
In September, Jinergy, as a result of improving the highest module efficiency of its HJT products from 21.68% to 21.85%, entered the list, increasing the count to 2. The number of products in this band remained at 2 through the end of 2023 and also during the first half of 2024 (See Growth In High Efficiency Solar Modules).
