Helio Connect GmbH

What Helio Connect GmbH does

Helio Connect GmbH is a Hamburg-based financial intermediation platform founded in 2024 that operates a B2B2C model for photovoltaic (PV) direct investments in Germany. The company curates and mediates parceled large-scale solar projects from leading German PV developers, distributing them through a partner channel of financial advisors (Finanz- und Vermögensberater), tax consultants (Steuerberater), and banks, who in turn offer these investments to their private-investor clients. End-investor demand is anchored in German regulatory incentives, including EEG subsidies and §7g EStG tax allowances (investment allowance and special depreciation), with the company offering an EY-authored Kurzgutachten to support advisor-led tax positioning.

The underlying technology is a digital sales, financing, and asset-management platform covering the full transaction lifecycle from partner onboarding and customer relationship management through financing arrangement and ongoing electricity marketing (Digitale Stromvermarktungs-App). Financing brokerage is delivered through a wholly-owned regulated subsidiary, Helio Finanz GmbH (operating under §34c Gewerbeordnung), which arranges up to 80% debt financing for PV projects. Adjacent offerings referenced on the company website include battery storage (Batteriespeicher) and EV charging (Ladesäulen) infrastructure. The company maintains sub-brands for press relations (Helio Presse) and partner training (Helio Education).

Revenue is generated through transaction commissions on mediated PV direct investments, supplemented by professional-services fees from the Helio Finanz GmbH financing brokerage. Pricing is not publicly disclosed. The company operates with a lean headcount of five employees from a WeWork office in Hamburg and is led by co-managing directors Fabio Griemens (Geschäftsführung) and Constantin Kossen (Vertriebsleitung/Geschäftsführung). At company level, Helio Connect has disclosed >€320M of investments secured, >1,000 investments mediated, 350 MW of PV capacity planned or sold in 2025, and a project footprint spanning at least seven German federal states, though specific revenue figures are not publicly disclosed.

Scale indicators5 records

Recent moves7 records

Expansion highlights5 records

Emerging players

• Enpal GmbH: Enpal is a leading German rooftop solar leasing and finance provider. While primarily a leasing rather than direct-investment model, it competes for the same pool of German household and SME customers interested in PV ownership economics.
• 1Komma5° GmbH: 1Komma5° is a fast-growing German energy transition company covering solar, heat pumps, EV charging, and electricity tariffs, and increasingly adjacent PV investment products. It overlaps with Helio Connect's end-customer base of sustainability-oriented private investors.

Direct peers

• Enerix GmbH: Enerix is a German PV franchise and direct-investment specialist offering parcelled solar park investments to private investors through partner advisors. It is the most direct head-to-head competitor in German PV direct-investment intermediation.
• ZOE Solar GmbH: ZOE Solar offers parcelled PV investments and rooftop/community solar projects to private investors, often via tax advisors and financial intermediaries. Comparable in product structure (parcelled PV projects with tax advantages) and German mid-market positioning.
• Sun Contracting GmbH: Sun Contracting places PV direct investments across multiple European markets via financial partners. Similar business model of parcelled solar park investments intermediated through advisor networks, although with broader geographic footprint than Helio Connect.
• reconcept GmbH: reconcept issues and places renewable energy investments, including PV direct investments, for German private investors. It competes in the same direct-investment placement channel via financial advisors and tax consultants.

Others

• Green Planet Energy eG: Green Planet Energy operates as a green utility that finances and builds renewable projects with citizen participation. It is comparable as a channel for sustainability-driven German consumers but does not directly offer parcelled PV direct investments.
• Solarwatt GmbH: Solarwatt is a German PV module and integrated system manufacturer with adjacent offerings for installers and end customers. It is comparable only thematically within the German PV ecosystem rather than as a direct investment intermediary.
• Project Finance & Capital Structuring advisory firms (e.g., Kaiser Partner): Specialist German project finance advisors structuring tax-driven PV investments for private investors. Comparable in their intermediation of financing solutions and tax-optimized investment structures, but typically project-by-project rather than platform-driven.

Broad incumbents

• EnBW Energie Baden-Württemberg AG: EnBW is a major German integrated utility with significant renewable energy generation and citizen-investment offerings (e.g., Windpark Bürgerwind). It competes for PV investor capital at a much larger scale and offers broader portfolio products.
