What Auxolar does

AUXOLAR GmbH is a Berlin-based, privately held B2B photovoltaic (PV) company founded in 2017 that delivers turnkey commercial and industrial solar installations across Germany under a full EPC (Engineering-Procurement-Construction) model. Its offering spans rooftop (Aufdachanlagen) and ground-mounted (Freiflächen) systems built on standard PV hardware — crystalline silicon modules, string inverters, mounting systems, battery storage, and smart-meter integration — packaged with free economic viability analysis, planning, procurement, installation, commissioning, and ongoing service and maintenance. Core customers are commercial and industrial enterprises (Gewerbe & Industrie), housing companies (Wohnungswirtschaft, including Mieterstrom/tenant-electricity models), and care/social-sector organizations (Pflege- & Sozialwirtschaft), with an additional surface in large-scale ground-mounted projects. Sales is direct and field-led, with industry-specialized representatives delivering on-site consultation from the Berlin headquarters and a Düsseldorf regional office serving North Rhine-Westphalia.

The business model is a hybrid of project-based EPC revenue and recurring service/PPA revenue. One-time revenue comes from system sales at €800–1,500/kWp depending on roof type, recognized on commissioning. Recurring revenue comes from service and maintenance contracts (monitoring, cleaning, repair) and from OnSite-Power Purchase Agreements (Stromlieferverträge) operated through wholly-owned subsidiary SOLSTROM UG, which lets clients consume solar electricity without upfront capital via long-term supply contracts. Marketing is B2B content-and-thought-leadership driven (LinkedIn, Xing, YouTube, regulatory/PV-knowledge blog) feeding enterprise inquiries through the company website. The firm holds VdS-recognized PV expert certification covering mechanical, electrical, and system competencies and is led by co-founders Florian Herrmann (CEO) and Uwe Lebelt (COO), with Philipp Armbrust as Head of Sales. No external funding or institutional investor has been disclosed.

Auxolar competitors and assessment

Company assessment

Emerging players

Zolar: Berlin-based digital solar platform providing online PV configuration, financing and installer-matching for residential and small commercial customers — overlaps Auxolar on the digital lead-gen and small-commercial side but is digital-first rather than EPC-led.

Broad incumbents

Krannich Solar: One of Europe's largest PV wholesalers/distributors with an associated installer network — competes with Auxolar on commercial PV supply and project delivery through its German channel.
Viessmann (Climate Solutions): German HVAC/heat-pump giant with an integrated PV, storage and heating offering for residential and light-commercial — overlaps Auxolar in commercial PV/storage segments but operates a much broader energy portfolio.
Solarwatt: Dresden-based established solar company offering PV modules, battery storage, charging, and energy management with both B2C and B2B routes — overlaps Auxolar in commercial PV + storage but operates a much broader product portfolio.
SENEC: German solar battery and PV-storage specialist (subsidiary of EnBW) offering residential and commercial storage-coupled PV — overlaps Auxolar's battery-storage and commercial PV components.
E.ON Solar/Heat Solutions: Major German utility's distributed energy division offers commercial and industrial rooftop PV with PPA-style contracting — competes with Auxolar's mid-market turnkey PV + PPA stack but as part of a much broader energy-services portfolio.

Direct peers

Enpal: Berlin-based solar leasing company that pioneered the zero-upfront-cost model with a PPA-adjacent structure; while originally residential, it has expanded into commercial solutions and competes head-to-head with Auxolar's Solstrom OnSite-PPA go-to-market in Germany.
1Komma5° (1point5): Hamburg-based green-tech company offering turnkey solar, heat-pump, EV charging and electricity-tariff solutions with a strong PPA/contracting model across the DACH region — closely overlaps Auxolar's PV-Komplettpaket + OnSite-PPA stack.
Goldbeck Solar: German EPC firm specializing in large-scale commercial, rooftop and ground-mounted PV projects with a turnkey delivery model — directly comparable to Auxolar's Aufdachanlagen and Freiflächen-PV offerings for commercial and industrial clients.
IBC Solar: German PV company (Bad Staffelstein) operating a vertically-integrated solar EPC + energy solutions business covering commercial rooftops, ground-mounted systems, and storage with proprietary system sales — directly comparable to Auxolar's commercial/industrial turnkey PV offering in Germany.
