Press release

Solora strengthens its position as an integrated energy partner with the acquisition of battery specialist Posetron

MERELBEKE / GENK, 5 March 2026

Solora, a leading player in both the construction and management of solar energy systems, batteries and charging stations, today announces the acquisition of Posetron, a company specialising in BESS (Battery Energy Storage Systems). With this strategic acquisition, Solora strengthens its position as an integrated energy partner that provides customers with a complete energy transition solution.

Solora is already positioned as an established player in the battery sector, and the acquisition of Posetron acts as a catalyst for the further expansion of these activities. Combining Posetron’s many years of expertise with Solora’s existing knowledge creates a powerful synergy, enabling Solora to further enhance its response to complex issues in energy storage, grid balancing and total cost of ownership optimisation for its customers. These aspects are becoming increasingly relevant within a context of constantly increasing grid congestion. A BESS helps optimize the size of the grid connection, and thus the associated grid costs, in relation to actual consumption.

Integrated solutions for complex energy issues

‘Our customers – from property developers and governments to industrial organisations – are no longer looking for separate components, but for integrated solutions,’ says Jan Van Der Haegen, co-founder of Solora. “By bringing Posetron’s expertise in-house, we can further improve services for our customers. We offer a solution to the entire energy issue: from generation and monitoring to storage and optimisation. This fits perfectly

with our strategy of providing our customers with a complete end-to-end service.”

Continuity and expertise assured

Posetron has built a strong reputation as an expert in battery systems. A crucial part of the acquisition is retaining this knowledge. Managers Chris Dirx and Frank Vandijck will therefore remain on board to lead the BESS activities within the Solora group.

‘For us, this is the logical next step,’ say Chris Dirx and Frank Vandijck. ‘We see enormous complementarity between our companies. By becoming part of the Solora group, we can offer our existing and new customers a broader range of services, while continuing to focus on what we do best: developing high-quality battery solutions tailored to customers’ needs.’

Geographical optimisation and international presence

This acquisition also strengthens the group’s geographical presence. By adding Posetron’s facilities in Genk to its head office in Merelbeke, Solora’s activities now cover the entirety of Flanders and the Netherlands. With these complementary locations, the group can respond more quickly and efficiently to customers throughout the region. This strong local presence, together with the active branches in the Netherlands and France, forms a solid foundation for the group’s further international growth.

The transaction is supported by investment funds Junction Growth Investors and BNP Paribas Fortis Private Equity, which joined Solora at the end of 2024 to reinforce its growth ambitions.
