What solago GmbH does

solago GmbH is a Germany-based direct-to-consumer e-commerce retailer of balcony solar power plants (Balkonkraftwerke) and associated photovoltaic components. Founded in 2022 in Hilden and headquartered in Düsseldorf-Reisholz, the company sells plug-and-play solar kits directly to residential end customers through country-specific storefronts (solago.de, solago.at, solago.nl, solago.be), bypassing traditional installer and wholesale channels. The company identifies itself as a market leader in German D2C balcony solar, reports more than 100,000 customers, operates with 101-250 employees and is entirely self-funded with no external investment.

Its core product line consists of Komplettsets — modular solar kits ranging from 800W entry-level balcony configurations up to 6000W+ rooftop systems — built around AIKO bifacial glass-glass modules under a Key Partner agreement and paired with Anker SOLIX battery storage at Diamond Partner tier (Solarbank 4 Pro expandable up to 30 kWh, plus Solarbank 3 Pro, 2 Pro and Max AC). The lineup also includes micro-inverters from Hoymiles and Deye, mounting systems for pitched, flat and trapezoidal roofs as well as balconies and ground, and accessories such as the Anker SOLIX EV wallbox, flexible solar modules and Power Dock. Customer-facing technology is delivered primarily through the Anker Edison App for system monitoring, while solago's own operational technology centers on a 22,000 sqm digitized warehouse in Düsseldorf-Reisholz that handles direct fulfillment.

The business model is one-time hardware retail to private households across German-speaking Europe, with a B2B wholesale adjunct via solarhandel24.de that addresses installer and trade demand. Revenue is generated through kit sales (modules plus inverter plus mounting) with attach-rate economics on storage and accessories, supported by a multi-tier supplier structure (Anker Diamond, AIKO Key, Deye and Hoymiles Minor). Beyond Germany, the company operates in Austria and is scheduled to enter the Netherlands and Belgium in April 2026, with the D2C storefront as the primary go-to-market and B2B wholesale as a secondary channel.

Expansion highlights5 records

Direct peers

• Otovo: Norwegian-headquartered D2C residential solar company operating across multiple European countries (Norway, Sweden, Germany, France, Spain, Italy). Directly comparable as a multi-market European residential solar retailer and a relevant benchmark for solago's international expansion ambitions.
• Zolar: German online solar platform offering D2C solar system sales with installation partner network. Directly competes with solago in the German residential solar market with a similar online-first customer acquisition approach.
• Enpal: German residential solar leasing company serving the same end-customer (homeowners seeking rooftop solar + storage). Although the business model is leasing rather than direct sale, both companies target the same balcony/rooftop solar buyer and compete for similar media and customer mindshare.
• 1Komma5°: German D2C/residential solar and home energy company with similar end customers (homeowners seeking solar+storage solutions). Backed by hundreds of millions in venture capital, it is one of solago's most direct competitors in the German balcony and residential solar market.

Broad incumbents

• SunPower: Established global residential solar company offering solar + storage solutions to homeowners. Comparable end-customer focus and product mix (PV + storage), though primarily US-centric and broader scale than solago.
• Solarwatt: Established German solar manufacturer and rooftop solar installer serving residential and commercial customers. A broad incumbent in German solar with overlapping end-customer segments, though primarily an EPC/manufacturer rather than a pure D2C retailer.
• Yello Solar: Solar arm of Yello, a major German energy retailer. Operates in residential solar as part of a broader energy portfolio, overlapping with solago's customer base but with a wider incumbent energy-services offering.
• Octopus Energy: UK-founded energy retailer expanding across Europe (including Germany). Offers solar + battery + EV-tariff bundles, directly competing for the residential solar+storage customer and increasingly relevant as solago expands into adjacent European markets.

Others

• Anker: solago's core storage partner (Diamond status) and increasingly a competitor. Anker SOLIX is expanding into complete balcony solar systems, putting Anker in the position of both critical supplier and emerging direct-to-consumer competitor.
• Enphase Energy: Global microinverter and home energy systems supplier. Relevant as a comparable in microinverter/balcony-solar category technology and increasingly offering complete residential solar+storage solutions in Europe.
