Soluxtec Resumes TOPCon Solar Module Production in Germany
German manufacturer restarts operations in Trier-Föhren following acquisition and facility upgrades.
1Production Restart in Germany
German manufacturer Soluxtec has officially resumed solar module production at its Trier-Föhren facility. This restart follows the company's acquisition by Chinese photovoltaic manufacturer Ronmaa. The factory underwent a comprehensive upgrade to its production lines, marking a significant operational shift after the company previously filed for insolvency in April 2026.
2Technological Shift to TOPCon
The facility has transitioned to manufacturing solar modules utilizing tunnel oxide passivated contact technology. This upgrade involves replacing the older M10 cell format with the more advanced G12-format cells. Soluxtec identified this technological pivot as a core component of its updated manufacturing strategy to remain competitive in the current market.
3Gradual Operational Scaling
Soluxtec plans to ramp up production capacity gradually over the coming weeks. While the company confirmed the modernization of its lines, it did not disclose specific figures regarding the annual production capacity of the Föhren plant. This measured approach aims to stabilize operations following the recent restructuring of the business entity.
4Strategic Partnership with Ronmaa
The acquisition by Ronmaa serves as a foundation for broader corporate goals. Beyond immediate manufacturing, the partnership is intended to support the expansion of Soluxtec's research and development activities. These efforts will focus on creating new photovoltaic products tailored for both residential and commercial and industrial applications within the European market.
5Context of Previous Insolvency
Soluxtec filed for insolvency in April 2026 due to intense international competition and falling module prices. At that time, the company employed 70 people across its Bitburg and Föhren sites. The Bitburg District Court appointed Jakob Joeres of the firm dhpg as the provisional insolvency administrator to oversee the restructuring process.
6Market Pressures on Manufacturers
The insolvency filing occurred amid sustained pressure on European solar manufacturers from low-cost overseas suppliers. Throughout 2024, European TOPCon module prices experienced sharp declines. These market conditions, combined with weak demand and high inventory levels, created significant financial challenges for regional manufacturers and distributors struggling to maintain their profit margins.
7Preserving Local Manufacturing Jobs
During the insolvency proceedings, management expressed a clear intent to maintain module deliveries and preserve existing jobs. By seeking new investors, the company aimed to restructure its business model rather than cease operations entirely. The successful acquisition by Ronmaa has allowed the firm to continue its 15-year history of module production.
8Future Industry Outlook
The resumption of production highlights the ongoing struggle of European manufacturers to adapt to global pricing trends. By integrating advanced cell formats and securing foreign investment, Soluxtec attempts to navigate a difficult landscape. Observers should monitor whether this model of international partnership can effectively sustain domestic production against persistent global competition.
