What Solarwatt Germany does

Solarwatt GmbH is a Dresden-headquartered, privately-held German solar energy company founded in 1993 that designs, sells, and supports an integrated home energy ecosystem for residential and commercial customers across the DACH region (Germany, Austria, Switzerland). Its product stack centers on proprietary glass-glass photovoltaic modules with a 30-year warranty, a lithium-based battery storage system (Battery vision), a string inverter (Inverter vision), EV wallboxes at 11 kW and 22 kW (Charger vision and Charger max, the latter bidirectional), and the SOLARWATT Manager energy management software that coordinates PV generation, storage, heat pumps (via Stiebel Eltron partnership), and EV charging through a single Home app, with integrations for dynamic electricity tariffs and the German THG-Prämie (greenhouse-gas quota bonus). The company's platform connects more than 130,000 devices across 25,000+ Manager installations, and its 750,000+ systems installed cumulatively in Europe underpin a recurring-services layer (Home plus subscription, dynamic tariff, THG facilitation).

Solarwatt's commercial model is a hybrid direct-and-channel go-to-market: 6 own regional installation teams (Dresden HQ, Bochum, Frankfurt, Kassel, Leipzig-Halle, Schaumburg via partner Ahrens Solar) deliver direct installations, while 400+ certified Fachpartner installers purchase through the B2B Pro portal, are trained via the SOLARWATT Academy, and handle end-customer sales, installation, and service. Pricing is quote-based and non-binding, configured per system, with no published list pricing. Revenue streams include one-time hardware sales of PV modules, storage, inverters, and wallboxes; professional installation and commissioning services; recurring subscription and optimization services (Home plus, dynamic tariff); and transaction fees on THG-Prämie claims (facilitated via carbonify GmbH). Notable commercial references include a 1,614-module installation at Olympiastadion Berlin, 66 retail sites with MPREIS (Austria), a 4,200-module canopy with EV fleet charging at DRÄXLMAIER Group, and enterprise sports/agriculture accounts; the core customer base, however, is residential single-family homeowners.

The company is led by CEO/CFO Benjamin Frank and CPO Peter Bachmann, with Dr. Achim Wörner as Chairman of the Supervisory Board, and is certified to ISO 9001, ISO 14001, ISO 45001, and ISO 50001, with TÜV SÜD customer satisfaction and a 4.7-star Google Reviews rating. The business combines a long-running German brand heritage with a software-integrated multi-product stack in a quote-driven B2B2C channel model.

Direct peers

• Senec (EnBW subsidiary): German home battery storage manufacturer (now owned by EnBW) offering integrated PV+storage solutions. Direct comparable to Solarwatt's residential battery storage and energy management offering in the DACH market.
• Fronius International: Austrian solar inverter and energy solutions manufacturer with residential solar offerings including storage and EV charging. Geographic neighbor and direct competitor in the DACH residential solar market.
• SMA Solar Technology: German-headquartered global leader in solar inverters and energy management solutions. Comparable as a DACH-based solar power electronics and home energy management provider, though Solarwatt is more vertically integrated into full systems.
• KOSTAL Solar Electric: German solar inverter manufacturer referenced in Solarwatt's data processing arrangements. Both serve the DACH residential solar market with inverters and energy management, with KOSTAL also offering a webshop.
• E3/DC: German residential energy system provider (part of Hager Group) offering integrated PV + storage + EV charging + heat pump solutions with proprietary energy management. Closest direct competitor to Solarwatt in the integrated home energy space in Germany.
• Sonnen (now Shell-owned): German home battery storage pioneer now owned by Shell, offering the sonnenBatterie plus integrated energy management. Direct comparable to Solarwatt's home battery + manager offering for residential customers in the DACH market.

Broad incumbents

• Tesla Energy: Global residential solar and storage player (Powerwall, Solar Roof, Wallbox) with similar integrated ecosystem ambitions. Comparable as a complete home energy stack, though serving primarily the US market with growing European presence.
• Viessmann (Climate Solutions): German heating and climate technology incumbent with growing solar, heat pump, and home energy solutions. Comparable to Solarwatt's heat pump integration and broader home energy offering, though Viessmann is much larger and more established in heating.

Emerging players

• 1Komma5° (1point5 degrees): German integrated clean energy company offering solar, heat pumps, EV charging, and dynamic tariffs on a subscription/as-a-service basis. Comparable end-to-end offering to Solarwatt Home but with a leasing business model that Solarwatt lacks.
• Enpal: German solar leasing company offering PV, battery, heat pump, and EV charging without upfront cost. Competes with Solarwatt in the DACH residential market but via a fundamentally different financing model.
