Qcells

What Qcells does

Qcells (legal entity: Hanwha Q CELLS GmbH) is a Germany-based solar photovoltaic and clean energy solutions provider founded in 1999 and operating as a subsidiary of South Korean conglomerate Hanwha Group. The company develops and manufactures high-efficiency crystalline silicon solar modules (Q.TRON series), residential and commercial battery storage systems (Q.HOME G4, Q.HOME+ ESS HYB-G3), hybrid inverters (Q.VOLT P-X), EV charging wallboxes, and a home energy management system (Q.HOME CONTROL), all integrated into complete solar kits. R&D is concentrated at the company's Thalheim, Germany innovation center, where approximately 200 experts achieved a world-record 28.6% efficiency on perovskite-silicon tandem solar cells in December 2024 and developed the first IEC-certified in-house perovskite tandem module.

Qcells generates revenue through four primary streams: hardware sales of modules and balance-of-system components via its online shop and certified Fachpartner installers; professional installation services delivered through the partner network; digital/energy management subscriptions via the Qcells Apps and Q.HOME CONTROL platform; and large-scale energy storage project development (e.g., the 190MW standalone BESS project in Texas financed with $150M from BNP Paribas and Crédit Agricole CIB). Distribution spans 13+ country-specific websites (Germany, USA, Korea, UK, France, Italy, Netherlands, Greece, Poland, Portugal, Hungary, Spain, Japan), a B2B market partner program for energy suppliers, and direct enterprise sales for utility-scale projects.

The customer base is diversified across four segments: residential homeowners (primary, served via Fachpartner network and shop.q-cells.com), B2B commercial and industrial customers (e.g., UNGER Kabel-Konfektionstechnik, Quintodecimo winery, Bahnhof Zorneding), utilities and project developers (US BESS pipeline), and a niche research/space segment (NASA SSTEF-1 lunar project). In autumn 2025, Qcells discontinued its B2C electricity and gas supply business (Q.ENERGY) to refocus on the solar core. The company is led by Managing Directors/Co-CEOs Dohyun Kwon and Sungyong Jung, with Danielle Merfeld serving as Chief Technology Officer and Daniel Myungil Choi as Managing Director and CEO.

Revenue model

1. Solar Modules and Hardware Sales: Sale of Q.TRON solar modules, battery storage systems (Q.HOME G4, Q.HOME+ ESS HYB-G3), hybrid inverters, wallboxes, mounting systems, and accessories. Products are sold through the online shop and via certified installation partners. Hardware sales represent a significant share of total revenue.
2. PV Installation Services: Complete photovoltaic system installation services delivered through a network of certified specialist partners (Fachpartner), including planning, delivery, and professional installation of PV systems. Pricing includes delivery and installation costs.
3. Electricity and Gas Supply (Q.ENERGY): Qcells supplies electricity and gas to residential and commercial customers in Germany under the Q.ENERGY brand. Customers receive their entire grid-connected electricity or gas supply through Qcells outside of basic supply. This includes green electricity and eco-gas products. Note: The B2C electricity/gas business was fully discontinued in autumn 2025.
4. Apps and Digital Services: Qcells provides various apps for homeowners to monitor energy consumption, manage PV installations, and optimize self-consumption. These apps provide direct access to generation and consumption data, enabling efficient control of solar installations.
5. Large-Scale Energy Storage Projects: Development and financing of utility-scale standalone battery energy storage systems (BESS), such as the 190MW BESS project in Texas, USA, funded through international banking partnerships.
