Lowest Representation Efficiency Band In TOP SOLAR MODULES Listing
The 21.7%-22.0% efficiency band remained the least represented category in the TOP SOLAR MODULES list, with no changes recorded over the last 2 years
Shrinking Mid-Efficiency Tier: Both the count and share of modules in the >22%-22.5% efficiency band declined from 2024 to 2025, from 20 to 9 and 36% to 20%, respectively, mainly due to products moving into higher-efficiency categories. (Source: TaiyangNews)
Efficiencies Between 22.0% And 22.5%
In the TOP SOLAR MODULES analysis, the 22.0%-22.5% efficiency band saw a steady decline in both product count and share as modules moved into higher-efficiency categories
High-Efficiency Expansion: The number of products in this band increased from 9 to 21, while its share rose from 16% to 47%, even as the total number of listed modules declined toward the end of the period. (Source: TaiyangNews)
Efficiency Band Above 22.5%
The highest efficiency band in the TOP SOLAR MODULES list expanded steadily between 2024 and 2025, driven by both new product entries and efficiency upgrades
