What Solera does

Solera GmbH is a German renewable energy systems integrator headquartered in Geislingen-Binsdorf, with additional locations in Stuttgart and Göppingen across Baden-Württemberg. Founded in 2008 and operating as a subsidiary of Thomas Preuhs Holding GmbH, the company delivers end-to-end photovoltaic, battery storage, heat pump, wallbox, and energy management solutions to both residential (B2C) and commercial (B2B) customers, with a cumulative installed base exceeding 10,000 systems. The company is ISO 9001 and ISO 14001 certified and operates a dedicated B2B division that serves commercial customers throughout Baden-Württemberg across multiple verticals including retail, manufacturing, banking, and agriculture.

The company's technology stack centers on an in-house Smart Energy Management System that orchestrates distributed energy assets — PV inverters, battery storage, heat pumps, and EV wallboxes — using weather forecasting and real-time device control to optimize self-consumption and grid interaction. Its product roadmap extends beyond PV into heating through the Hypernova heat pump, developed in partnership with Ritter Energie. The business model combines project-based hardware sales for residential and commercial customers with a growing PV All-inclusive subscription that bundles hardware, monitoring, and service into a recurring contract. A financing partnership with LBS Zollernalb supports end-customer conversion, while the Preuhs-Campus and Energie-Sundowner B2B event series function as ecosystem-building tools for installers, OEMs, and commercial clients.

Solera employs roughly 100 staff distributed across sales (3-4 B2C account managers, 7-8 B2B account managers), project management, and installation crews, with a leadership team whose principals bring more than 20 years of solar industry experience. The go-to-market relies on regional sales coverage, trade partnerships, and regulatory tailwinds from Baden-Württemberg's PV-1 and PV-2 solar mandates and federal heat pump subsidies. No revenue, funding, or external valuation data is disclosed in the available input.
