What Galaxy-energy does

Galaxy Energy GmbH is a privately held, family-owned German manufacturer specializing in building-integrated photovoltaics (BIPV). Founded in 1992 (originally as Galaxy Sport, restructured as Galaxy Energy GmbH in 2005), the company is headquartered in Berghülen, Germany, and operates a single integrated site that combines headquarters, production, training academy, and a working plus-energy pilot building showcasing its own technology. The company's flagship Indachsystem is an in-roof BIPV architecture in which glass-glass PV modules — produced in-house since 2008 via autoclave lamination using bifacial half-cut TopCon cells — serve as the primary roofing material, replacing conventional tiles while generating electricity and allowing controlled daylight transmission. Around this core system, Galaxy Energy has built a portfolio of BIPV sub-products (terrace, balcony, carport, bikeport, facade, agricultural/equestrian buildings, parkhaus, industrial halls, new construction, renovation) plus complementary hardware (own-brand LFP storage, Tesla Powerwall, SolarEdge/Victron inverters, EV chargers), all manufactured or assembled under ISO 9001/14001 processes.

Revenue is generated primarily through B2B wholesale of hardware to a network of 375 certified partner firms and 936 trained BIPV installers across 14 countries, with additional minor revenue from certified installer training (€120 per day per program). Direct sales and field-project engagement are reserved for complex commercial and prestige projects. The channel is gated: installers must complete theoretical and practical certification to access wholesale pricing and to qualify the project for a 20-year watertightness guarantee. End customers span agriculture, equestrian, automotive, manufacturing, education, municipal, hospitality, and residential verticals, with no disclosed concentration in any single account. The company is bootstrapped, holds 100% Schöll-family ownership, completed a second-generation leadership transition in 2018, and holds a US BIPV patent plus an extensive certification stack (IEC, TÜV, BRoof, DLG, JETPVm, HypoVereinsbank bankability) as competitive entry barriers.

Revenue model

1. BIPV Systems and Components: Primary revenue from selling complete BIPV systems, including glass-glass PV modules, aluminum mounting profiles, sealing systems, and all required components for in-roof installations. Revenue is predominantly hardware-based with one-time sale of physical products.
2. Montagesysteme (Mounting Systems): Sales of various mounting systems including Aufdach (on-roof), Quick Click (ground-mounted), Forty Fast Fix, and G7 Klemmen. These are accessory products for both BIPV and conventional PV installations.
3. Speicher und Batterien (Storage Systems): Sales of battery storage systems including own-brand Galaxy Energy storage products (V10, VR10, W1 LFP batteries, battery cabinets up to 51.2kWh) and Tesla Powerwall products.
4. Wechselrichter (Inverters): Sales of inverters from SolarEdge and Victron Energy brands, along with optimizers and related electrical components.
5. Ladestationen (EV Charging Stations): Sales of electric vehicle charging stations including Galaxy Energy M3W Wallbox.
6. Schulungen (Training Programs): Revenue from training programs for certified installers. BIPV training costs 120€ per day (1 day, 08:00-18:00). Storage training costs 120€ per day (1 day, 08:00-15:00). Combined BIPV + Storage training also available.
7. Photovoltaikmodule (PV Modules): Sales of proprietary Galaxy Energy PV modules including GS-series and new GG-series glass-glass modules with various power ratings.
