Solarfocus GmbH

What Solarfocus GmbH does

SOLARFOCUS GmbH is an Austrian manufacturer of renewable heating systems, founded in 1993 and headquartered in Sankt Ulrich bei Steyr, Austria. The company designs and produces a comprehensive product portfolio spanning biomass boilers (pellet, log wood, and wood chip units from 10 kW residential up to 300 kW commercial, with cascade configurations reaching 1800 kW), solar thermal collectors including a proprietary CPC (Compound Parabolic Concentrator) line, air source heat pumps (the vampair series with R290 propane refrigerant variants claiming COP up to 5.1 at A7/W35), fresh water modules for instantaneous domestic hot water, and energy storage. Notable technical differentiators include the airtight CPC collector geometry that captures oblique and diffuse sunlight, Lambda probe-controlled wood gasification combustion, and proprietary inverter interfaces that integrate with Fronius, SolarEdge, and Huawei PV systems to optimize self-consumption of solar electricity.

The business operates a 100% indirect go-to-market model, selling exclusively through specialist heating installers (Fachhandwerker), commercial wholesalers, and certified national distribution partners — never directly to end consumers. Distribution spans over 20 European countries, with wholly-owned sales entities in Austria (HQ), Germany (Lorsch distribution center operational since October 2015 with 4,100 m² of offices, warehouse, training, and exhibition space serving over 750 German partners), and Switzerland (Altishofen, via SOLARFOCUS Schweiz GmbH). UK distribution runs through three named partners and Ireland through two. Revenue is generated through hardware sales (boilers, collectors, heat pumps, accessories, and PV modules) plus ancillary service, maintenance, and spare parts via the certified partner network. Pricing is quote-based, not publicly disclosed; standard trade terms are 2% skonto within 8 days or net 20 days.

SOLARFOCUS employs 42 people, holds EN ISO 9001 certification, and is privately held by its managing directors (Johann Kalkgruber, Johann Großauer, Johann Hinterplattner, with Joachim Kalkgruber and Florian Großauer also in management, suggesting family/founder ownership across generations). The company has no disclosed external funding, no parent company, and no M&A activity in the source data. Customer-facing digital tools include the mySOLARFOCUS iOS/Android app and the SOLARFOCUS Connect web portal for remote monitoring and control.
