In H1 2025, the 3rd band in TOP SOLAR MODULES maintained 2 HJT products with a constant 4% share
Stability followed Jinergy’s September 2023 entry; earlier, Trinasolar and Qcells exited after efficiency upgrades, leaving Meyer Burger alone until then
This range mainly functions as a transitional stage, since PERC products start above it, and advanced technologies quickly progress to higher efficiencies
For easier analysis of the TaiyangNews TOP SOLAR MODULES report, we outlined the development of module efficiencies across 4 bands: >22.5%, >22% to 22.5%, >21.7% to 22%, and 21.5% to 21.7%. With the first 2 bands covered in our previous articles, we cover the 3rd band, i.e., >21.7% to 22%, in this article.
This efficiency band continues to be the least represented in the TOP SOLAR MODULES list. In H1 2025, the number of products remained unchanged at 2, maintaining a constant 4% share from January through June. These 2 HJT products – one from Jinergy at 21.85% and the other from Meyer Burger at 21.8% – were the same modules that had represented the band throughout 2024 and the latter part of 2023. In 2024, the band remained largely static. From January to December, it consistently held a product count of 2 and a 4% share. This stability followed the pattern set in late 2023, after Jinergy entered the listing in September by improving the efficiency of its HJT module from 21.68% to 21.85%, joining Meyer Burger as the second product in this range (see 22%-22.5% Efficiency Band: No More A Gateway).
In contrast, 2023 saw more movement in this band. The year began with 3 products, corresponding to a 9% share. One product dropped off the list in April, reducing the count to 2 and the share to 5%. Another exited in June, leaving only one product and bringing the share down to 3%, and further to 2% by August. The entry of Jinergy in September restored the count to 2 and raised the share to 4%, which then held steady through the end of the 2023.
At the beginning of 2023, the 3 products in this band came from Trinasolar, Qcells, and Meyer Burger. Trinasolar, listed since September 2022, exited in early 2023 after improving its module efficiency from 21.9% to 22.5%. Qcells followed in May by increasing its efficiency from 22% to 22.3%, leaving Meyer Burger as the sole occupant of the band until Jinergy joined later that year (see Highest Solar Module Efficiency Band).
The low representation in this band is mainly due to the fact that entry-level efficiencies for PERC are already above this range, while those for advanced technologies tend to move quickly beyond it. As a result, this band serves more as a transitional space, with most advanced products progressing to higher efficiency levels once commercialized.
