1punkt5 Gmbh

What 1punkt5 Gmbh does

1punkt5 GmbH is a German turnkey commercial and industrial (C&I) solar contractor founded in Q3 2018 in Bremen and now headquartered in Ottersberg. The company plans, builds, and operates commercial photovoltaic (PV) systems, large-scale battery storage solutions, and energy management systems for energy-intensive industrial customers across Germany, with offices in Ottersberg, Hamburg, Bremen, Oldenburg, and Veldhausen supporting its northern German focus.

Its core technology stack combines rooftop, ground-mounted, and floating PV installations (cumulative capacity of 100 MWp as of Q1 2025 across approximately 263,000 m²), industrial-scale battery storage with average payback periods under four years, and energy management software that integrates electricity, heat, and mobility sectors. The company has demonstrated technical differentiation through pioneering projects such as the first floating PV installation in Lower Saxony and through integrated storage-plus-PV deployments that achieve 20-70% self-sufficiency on customer sites. Notable reference customers include Häcker Küchen, MEGA Tierernährung, Albers Logistik, Böckmann Fahrzeugwerke, Diephaus Betonwerke, Papier- und Kartonfabrik Varel, and BLUME2000.

1punkt5 generates revenue through three streams: (1) one-time turnkey EPC project fees for PV and storage installations, (2) recurring managed services for ongoing operations and maintenance, and (3) a subscription-style energy contracting model offered through sister company 1P5 NRG GmbH (launched September 2024) under which customers host installations and receive solar electricity at rates up to 50% lower than grid prices without capital outlay. The company operates direct enterprise field sales targeting manufacturing, logistics, packaging, and agricultural Mittelstand customers, is privately held as a GmbH, is backed by shareholders HZI Gruppe (packaging) and SCHULZ Systemtechnik (automation), and is led by Managing Director Sönke Jäger. Revenue is not publicly disclosed.
