WIRSOL Roof Solutions

What WIRSOL Roof Solutions does

WIRSOL Roof Solutions (legal entity: WIRSOL Aufdach GmbH) is a regional German photovoltaic engineering, procurement, and construction (EPC) provider headquartered in Waghäusel, Baden-Württemberg, founded in 2003. The company designs, installs, and services rooftop solar systems for three primary customer segments: private households, commercial and industrial businesses (including logistics, manufacturing, food and beverage, and agriculture), and public-sector and non-profit clients such as municipalities, religious institutions, and sports clubs. As of recent disclosure, the company has completed more than 16,000 PV installations with cumulative installed capacity of approximately 1,600 MW, supplying over 500,000 households with green electricity and contributing to roughly 1,008,000 tons of annual CO2 savings.

The core technology stack is centered on rooftop photovoltaic systems, supplemented by integrated add-on modules: battery storage (Stromspeicher), EV charging infrastructure (Elektromobilit\u00e4t/Ladestationen), and medium-voltage grid construction including transformer stations for larger solar parks. Supporting services include professional PV cleaning (delivered via partner Meteor Nofer GmbH starting at \u20ac490 net), comprehensive maintenance and 24/7 monitoring, warranty and insurance handling, civil and underground cable works, and surface preparation. A distinctive operational asset is the Solarteur Camp Rhein-Neckar training center in Industriepark Philippsburg, established in 2023, which provides in-house certification of PV mounting specialists using hands-on practice with original components and manufacturer cooperation.

WIRSOL's business model combines one-time project revenue (system sales and installation services) with recurring service revenue (maintenance contracts, monitoring, cleaning). Go-to-market is consultation-led and regional: the company runs free expert consultations, an online savings-potential calculator, capped 20-person in-person Infoabend Photovoltaik events with live roof analysis, and direct sales teams for residential and enterprise pipelines. Distribution is exclusively direct within the defined service area, with no disclosed resellers aside from the partner-led cleaning offering. Pricing is project-specific (varies by system size, roof type, and configuration), with published unit pricing only for the cleaning service tier. The company invests a stated minimum of 20% of its revenue into its own photovoltaic projects for CO2 removal and holds a CrefoZert creditworthiness certificate valid through May 2026.

Others

• Memodo: German PV wholesale distributor supplying modules, inverters, and storage to installers including WIRSOL's peers; not a direct competitor but a key upstream supplier shaping the cost structure of WIRSOL's project pipeline.

Direct peers

• Solarwatt: Dresden-based German manufacturer of glass-glass PV modules and battery systems that also sells and installs complete rooftop systems; overlaps WIRSOL on premium residential and commercial PV plus battery storage bundles.
• DZ-4: German mid-sized PV installer active in southern Germany offering residential and commercial rooftop systems, storage, and EV charging; closely comparable regional competitor to WIRSOL in project size, customer mix, and service-area model.
• 1Komma5°: Hamburg-headquartered climate-tech company rolling up regional German solar, heat pump, and EV-charging installers under a unified brand; competes head-to-head with WIRSOL in residential and small-commercial PV across multiple German states.
• Enerix: German specialist franchise for decentralized solar and storage with regional partner offices across southern Germany including Baden-Württemberg; directly comparable regional installer model competing for the same residential and SME PV customers.
• Enpal: Berlin-based solar leasing and installation company serving German residential customers with a financed, subscription-style PV offering — directly comparable to WIRSOL's residential rooftop segment, but with a national digital-acquisition model.
• IBC Solar: Bad Staffelstein-based PV system house offering modules, inverters, and project execution for residential, commercial, and solar-park customers; comparable to WIRSOL in end-to-end rooftop and large-project delivery, with additional wholesale/distribution scale.
• Zolar: Online PV comparison and installation platform connecting German homeowners to regional installers, including Baden-Württemberg; a direct competitor for the same residential rooftop leads WIRSOL targets via its digital cost calculator and consultation funnel.

Emerging players

• Sonnen (Shell-owned): Wildpoldsried-based battery storage specialist (now part of Shell) increasingly bundling PV with home storage; a relevant adjacent competitor for WIRSOL's battery-storage add-on and integrated energy offering.

Broad incumbents

• E.ON: One of Germany's largest energy utilities offering rooftop PV, storage, and heat pumps as part of a broad residential energy-services portfolio; competes with WIRSOL on both residential and C&I customers, but as a mass-market incumbent rather than a regional specialist.
