Germany Merbitz 72 MW Utility Project: Setting a New Benchmark for High-Yield Solar Performance in Europe
ESG Kraftwerke Wettin GmbH & Co. KG & Bejulo GmbH · Wettin-Lobejün-Merbitz, Germany · 2026
A 72 MW utility-scale solar power project was commissioned in Wettin-Lobejün-Merbitz, Germany, utilizing AIKO's advanced ABC (All Back Contact) solar module technology. The project was developed to maximize energy production, enhance long-term financial returns, and support Europe's transition to renewable energy. AIKO supplied over 110,000 high-efficiency ABC modules, delivering industry-leading performance, reduced degradation, and superior power generation in comparison to conventional TOPCon modules. The installation is expected to generate approximately 84.94 GWh of clean electricity annually while significantly reducing carbon emissions. The project demonstrates how next-generation solar technology can improve energy yield, lower LCOE (Levelized Cost of Energy), and optimize land utilization for large-scale utility projects across Europe
Solution: With the site now producing, the technical and economic advantages of AIKO’s ABC modules have moved from design to reality. AIKO’s ABC modules, AIKO-G-MCH72Dw (2382×1134×30mm), deliver 24.0% efficiency and a power output of 645/650Wp,providing 30 W more power than leading TOPCon products within the same module area. Superior partial-shading performance ensures stable output even when modules are affected by dust, vegetation, or structural shading. Low degradation rates (first-year ≤1%, annual 0.35% from year 2 to 30) further support long-term energy yield.
Outcome: 72 MW utility-scale solar installation operational. 84.94 GWh annual electricity generation. 29,219 tonnes annual CO₂ emissions reduction. €108.85 million projected lifecycle revenue. Improved project IRR and reduced lifetime energy costs. Established a new benchmark for high-efficiency utility-scale solar projects in Europe.
