What SOLARWATT GmbH does
SOLARWATT GmbH is a German privately held solar energy company headquartered in Dresden, founded in 1993, that designs and distributes integrated residential and commercial energy systems. The company operates across 16+ European countries through a network of certified installers, heating experts, and energy consultants, supplemented by direct website sales and a professional partner portal (solarwatt.pro). Its product portfolio centers on the SOLARWATT Home system, which combines photovoltaic modules, battery storage, heat pumps, EV chargers, and the proprietary SOLARWATT Manager — a home energy management platform that orchestrates energy flows between generation, storage, and household loads to maximize self-consumption.
Underlying technology draws on in-house testing, TÜV certification, and ISO 9001/14001/45001/50001 certified manufacturing. The Manager is positioned as the integration layer for the full hardware stack, and through a strategic partnership with BMW Group — expanded in 2026 — it will support Vehicle-to-Home functionality linking BMW Neue Klasse EVs (iX3, i3) to the home energy ecosystem via the BMW Wallbox Professional bidirectional charger. Power-electronics capabilities in inverters and storage were deepened by the 2022 acquisition of Dutch developer REConvert. A 2022 Harvard/Wharton research study analyzed 3,200 SOLARWATT customer households and projected that 54% of German households could economically adopt solar-battery systems as costs fall and electricity prices rise, with a potential 38% reduction in household grid demand.
The revenue model combines one-time hardware sales (panels, batteries, heat pumps, EV chargers) with a recurring subscription energy management software stream and a service/warranty layer delivered through the partner network. Pricing is quote-based rather than publicly disclosed. The primary customer segment is residential homeowners seeking energy independence and lower electricity costs, with a secondary commercial/business segment. Leadership consists of Benjamin Frank (CFO/CEO), Peter Bachmann (CPO), and Dr. Achim Wörner (Chairman of the Board).
