Top PV Modules with Highest Conversion Efficiency in May 2025!

Recently, TaiyangNews released the May 2025 edition of the "TOP SOLAR MODULES Listing" report. This month's listing includes 50 solar modules from 32 companies that have achieved commercial mass production and shipment. The number of companies and products remains the same as last month, but the efficiency/ranking of two modules has changed.

The most notable change in this month's listing comes from Trinasolar, whose Vertex N series module efficiency increased from 22.5% to 23%, propelling its ranking from 16th to 5th place in the listing, thereby affecting the rankings of other products in the listing as well.

In addition, Hanwha Qcells updated the data for its PERC modules, increasing the power by 600W while maintaining a module efficiency of 21.5%. See the table below for details:

Background

Among the various indicators used to measure the performance of solar modules, conversion efficiency and output power are the two most critical parameters. Although there are many ways to increase module power, such as using larger solar cells or integrating more solar cells into a module, it is the conversion efficiency that truly reflects the module's ability to convert light energy per unit area. Therefore, TaiyangNews's TOP SOLAR MODULES Listing only includes the most efficient commercial PV modules.
