STRELEC Gruppe

What STRELEC Gruppe does

STRELEC Gruppe is a German privately-held services group headquartered in Filderstadt, Baden-Württemberg, operating three integrated service divisions: STRELEC Elektro (electrical project planning and installation for construction and industrial clients, covering low- and medium-voltage systems, lighting, data networks, fire-alarm systems, building automation, switchgear construction, and industrial machinery), STRELEC Fachkräfte (placement of qualified tradespeople — electricians, masons, welders, mechanics, HVAC technicians — in supervised teams of 2–4 with German-speaking foremen), and STRELEC Solar (planning and installation of photovoltaic infrastructure, storage solutions, and wallboxes for residential customers typically up to 30 kW/p and commercial customers from 30 kW/p). The group is the sole shareholder of four operating subsidiaries — MS Gruppe s.r.o. (Slovakia, 2014, the workforce-sourcing entity), MS Bau GmbH (2015), MS Industrial GmbH (2018), and STRELEC Solar GmbH (2022) — and serves customers across at least four German states (Baden-Württemberg, North Rhine-Westphalia, Rhineland-Palatinate, Hesse) plus Slovakia.

The group's revenue model is project-based professional services, with disclosed electrical-installation contracts ranging from approximately €455,000 to €1,365,000 per project. Go-to-market is sales-led and direct: B2B clients engage through dedicated sales leadership (Vertriebsleiter, Projektleiter Elektro, Teamleiter Vertrieb & Beratung Solar) for project bids and workforce contracts, while solar services are sold direct-to-consumer for residential customers via consultation, installation, and registration handling under an "all-inclusive" package. Pricing is quote-based per project rather than standardized, and the customer base spans commercial/industrial clients (e.g., Cummins Hydrogenics), government and military projects (fire stations, military housing, schools), and healthcare facilities (Rheumazentrum Mittelhessen, Altenpflegezentrum).

Group revenue grew from €160,000 in the founding year (2013) to €7.4 million in 2021, with the company recognized as Focus Business Wachstumschampion 2025 (rank 1 of Top 500) and ranked 40 of 1,000 in the FT1000 Europe's Fastest Growing Companies 2025 ranking. The company is founder-owned (Michal Strelec, Managing Director) with no external investors and operates without a software, API, or AI-enabled technology layer.

Emerging players

• Zolar GmbH: German online solar platform connecting customers to installation partners. Comparable as a residential solar channel player; partial overlap since STRELEC Solar serves the same end market through direct sales.
• Belectric GmbH: German solar EPC and operations company. Comparable as a German solar installer with overlap in the PV infrastructure market, though more focused on utility-scale projects than STRELEC's residential/commercial emphasis.

Direct peers

• Persona Service AG & Co. KG: Major German staffing company for industrial and commercial trades. Comparable as a provider of skilled workers (electricians, welders, mechanics) to German industrial clients, mirroring STRELEC Fachkräfte's staffing model.
• 1Komma5° GmbH: Fast-growing German solar installer and energy services company offering PV, heat pumps, and e-mobility. Comparable as a German solar installer competing in the same residential and small commercial segment, though with significantly more external funding.
• Eltel Group: European specialist in electrical infrastructure, power distribution, and telecom networks. Closely comparable business model focused on electrical installation services for utilities and infrastructure clients across Europe.
• Enpal GmbH: Germany's leading residential solar leasing company. Directly competes with STRELEC Solar in the German residential PV market, though with a venture-backed leasing model rather than direct-sale installation.
• ROM Technik GmbH & Co. KG: German facility-services and technical building equipment contractor specializing in electrical, HVAC, and energy solutions. Comparable mid-market German contractor with overlapping service lines in electrical installation and energy systems.

Broad incumbents

• SPIE SAG GmbH: One of Germany's largest electrical infrastructure and facility-services contractors, providing electrical installation, energy infrastructure, and industrial services. Comparable as a broad incumbent competing in the same German electrical contracting market, though at much larger scale and with a national footprint.
• Caverion Deutschland GmbH: European building equipment and technical services contractor with strong German presence. Comparable as a multi-trade building equipment contractor providing electrical and HVAC services to commercial and industrial clients.
• WISAG Industrie Service GmbH: Major German facility-services provider covering electrical, mechanical, and industrial maintenance. Comparable as a multi-trade services incumbent serving industrial and commercial clients across Germany, with similar vertical exposure.
