BISOL Group Integrates G12R Solar Cell Technology into New Product Line

Latkova vas, Slovenia, May 6, 2025 – BISOL Group, Europe’s largest PV module manufacturer, proudly announces the successful integration of the advanced G12R solar cell dimension into its production lineup. This strategic upgrade marks a significant milestone in BISOL’s commitment to cutting-edge solar innovation and quality European manufacturing.

Beginning in the second quarter of 2025, BISOL transitioned from M10 to the more efficient G12R cells across its portfolio. This shift follows an intensive period of R&D, during which BISOL’s laboratories developed the optimal material composition and production processes required to overcome the early limitations experienced by other adopters of G12R technology. Only after extensive real-life condition testing and multiple iterations of material composition were the products deemed ready to carry the trusted Made in EU warranty, reinforcing BISOL’s dedication to European quality, responsible sourcing, and traceable production.

“With the G12R upgrade, we are not just adapting to a new standard—we are setting it,” said Dr Uros Merc, Co-Founder and President of BISOL Group. “Thanks to our in-house technological expertise, we are delivering next-generation modules that exceed expectations in performance, reliability, and sustainability. Solar products carry long lifetime warranties, so the technology must be fully matured before implementation.”

This advancement supports BISOL’s long-term vision of leading the solar energy transition with solutions that are both technologically advanced and environmentally responsible. The first clients and partners have already received the new products, while the final batch of the previous PV module generation will be fulfilled for existing orders by mid-June.
