What Eturnity AG does

Eturnity AG is a Swiss B2B SaaS company headquartered in Chur that builds workflow software for solar and renewable energy installers. The company's core product, Eturnity Expert, is a cloud-based platform covering the full installation lifecycle — lead generation, offering and sales, planning and design, and project coordination/administration — with a complementary Eturnity Calculators sub-product that enables self-service PV design for end customers. Functional modules include 2D and 3D layouting (with drone and GLB model imports), advanced energy simulation (profiles, remuneration models, system efficiency, shading loss, MCS UK compliance), bill-of-materials management, a supplier-subscribed component library (PIM) with auto-pricing and VAT handling, and multi-tech calculators spanning PV, heating, EV charging and battery systems. The company integrates with 500+ third-party tools including mounting-system OEMs (Van der Valk, Esdec, K2), a major European solar distributor (Krannich), heating OEMs (Stiebel Eltron) and workflow tools (Zapier, Make, Bexio, DocuSign).

Eturnity's business model is B2B SaaS subscription, targeting SMB to mid-market solar and energy installers across Europe. The go-to-market is hybrid: a product-led self-serve funnel via free trial and embeddable lead-generation calculators, paired with a demo-driven enterprise sales motion for larger mid-market accounts. Named reference customers — Solarstrom Niederrhein GmbH, Actensys and Solarmarkt — are SMB installers and distributors reporting outcomes such as 30% higher conversion rates, 75% time savings and 5-10 minute quote generation. Pricing is not publicly disclosed and appears to be quote-based for larger deployments.

Following its March 2026 merger with Netherlands-based Solar Monkey, the combined entity serves 2,500+ installers across 8+ European countries and is backed by Klima (lead Series A investor, June 2023, CHF 8 million) together with Junction, Eneco Ventures and Helen, which invested fresh capital alongside the merger. Eturnity is led by founder and CEO Matthias Wiget, with headcount in the 51-100 range.

Direct peers

• Aurora Solar: US-based SaaS for solar design, sales, and installation; offers 3D design, proposal generation, and workflow tools to residential and commercial installers globally. Direct competitor to Eturnity's core solar PV design and quoting modules, and Aurora Solar's logo appears on Eturnity's customer page, suggesting direct market overlap.
• OpenSolar: Global cloud-based solar design and sales platform used by residential and commercial installers for system design, proposals, and project management. Competes head-on with Eturnity Expert across lead generation, quoting, and design workflows.
• Solargraf: Solar design and proposal SaaS for installers, covering shading analysis, system sizing, proposals, and CRM. Comparable to Eturnity's Planning & Design and Offering & Sales modules.
• PVcase: Solar design and engineering software focused on utility-scale and C&I projects, with AutoCAD/Revit-based layout tools. Adjacent competitor to Eturnity's 2D/3D layouting and engineering simulation modules.
• PVsyst: Swiss-origin PV system simulation and yield-analysis software widely used for detailed energy simulation. Comparable to Eturnity's Advanced Energy Simulation module (shading, system efficiency, remuneration models).
• Pylon (Enphase): Spanish-origin solar design SaaS (now part of Enphase) used by European installers for residential PV system design and sales. Direct overlap with Eturnity's core installer workflow in southern European markets.

Broad incumbents

• Enphase: Global energy technology company offering inverters, batteries, and an installer-facing design tool (via Pylon). Competes with Eturnity indirectly through hardware-tied design software for installers.
• SolarEdge: Global solar inverter and energy solutions provider offering its own Designer tool for system planning. Overlaps with Eturnity on PV system design but as part of a broader hardware-led portfolio rather than a standalone SaaS.
