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.
