EWIA, SunErgy Merge Solar Operations

April 09, 2025

Key Figures & Findings: German solar firm EWIA Green Investments GmbH is acquiring mini-grid developer SunErgy, expanding its reach across sub-Saharan Africa. The deal aims to strengthen EWIA’s presence in decentralized energy, aligning with its focus on solar systems for commercial and industrial users. EWIA, based in Hamburg, has been active in Ghana, Côte d’Ivoire, and Senegal, offering full-stack services from planning to operation. Founded in Norway and operating from Germany, SunErgy GmbH has built its mini-grid footprint primarily in Cameroon through subsidiaries SunErgy Ltd and 2 Mites Ltd. This move formalizes a prior alliance with German investment firm KGAL GmbH & Co, which invested in SunErgy in 2019.

Insights: SunErgy’s solar mini-grids are directly connected to customers’ buildings, operating via localized power grids and enabling last-mile electrification in underserved African markets.

Future Implications: By 2025, EWIA could use this acquisition to accelerate the deployment of decentralized solar systems across new markets. The partnership may also boost investment in off-grid energy models that blend telecom infrastructure and solar access in rural Africa.
