A Vietnamese pioneer shaping a “Make-in-Vietnam” energy model for the ESG era As the world enters the ESG era, where Environmental, Social, and Governance standards define sustainable growth, mastering clean energy is no longer a trend, but a strategic capability.
In Vietnam, SolarBK Holdings stands as one of the few enterprises that has built a comprehensive renewable energy value chain, “Make-in-Vietnam, International Standard”, empowering businesses, households, and communities to move toward a green future.
IREX – Mastering Manufacturing and Quality from the Start At the foundation of this value chain lies IREX, SolarBK’s solar cell and module manufacturing plant in Vũng Tàu, boasting an annual capacity of 350 MWp, a fully automated production line, and an international-standard laboratory dedicated to innovation and new technologies.
IREX not only manufactures but masters technology, with products certified by IEC, UL, TUV, and MCS, meeting the highest international standards for export to Europe, the U.S., and Australia.
IREX’s “Make-in-Vietnam” solar cells have been powering landmark green projects across Vietnam — from off-grid hybrid systems on remote islands, where SolarBK brought energy to the nation’s frontier, to the LEGO Factory at VSIP III (Bình Dương), the group’s first carbon-neutral factory in Asia.
In central Vietnam, Phu An Yarn Factory (Huế) and Leading Star (Thanh Hóa) operate large-scale rooftop solar systems that reduce thousands of tons of CO₂ each year. In the commercial and service sectors, AEON Mall Tân Phú (HCMC) and various Vingroup facilities have chosen IREX solar modules to align with their green energy strategies, demonstrating how “Make-in-Vietnam” technology can compete globally.
SolarBK – Innovating Clean Energy Technology & Engineering Solutions If IREX is the foundation, SolarBK is the technological heart of this clean energy ecosystem.
It’s where research meets real-world application, turning laboratory innovations into renewable solutions.
SolarBK provides end-to-end EPC (Engineering – Procurement – Construction) services, from project development and design to technology supply, construction, and commissioning.
In parallel, its O&M (Operation & Maintenance) services ensure long-term system performance, supported by SSOC (Smart Solar Operation Center), a proprietary smart monitoring system enabling real-time performance tracking, predictive alerts, and operational safety.
SolarESCO – Enabling Green Finance for Sustainable Growth To help businesses transition to clean energy without upfront investment, SolarESCO – a SolarBK subsidiary – provides financial and operational models for large-scale renewable projects.
Under the ESCO/PPA model, SolarESCO invests, operates, and maintains the system, while customers pay based on actual energy savings achieved.
This approach allows factories and industrial zones to reduce energy costs, meet ESG goals, and ensure financial sustainability simultaneously.
SolarGATES – Bringing Clean Energy to Millions of Vietnamese Rooftops Completing the value chain is SolarGATES, the nationwide distribution and service network for clean energy solutions.
Through BigK and BigK+ solutions, SolarGATES delivers standardized, high-quality rooftop solar systems to households and SMEs, backed by official warranty and after-sales service from SolarBK.
SolarGATES also partners with banks, insurers, and financial institutions to introduce green credit and solar insurance programs, making clean energy accessible and affordable for all Vietnamese families.
A Closed Value Chain with an Open Vision for the ESG Era Together, IREX, SolarBK, SolarESCO, and SolarGATES form a complete “Make-in-Vietnam” renewable energy value chain.
SolarBK not only masters technology but also redefines how clean energy creates sustainable value for people, enterprises, and the nation.
From the first off-grid systems on Vietnam’s islands to carbon-neutral factories and ESG-driven enterprises, SolarBK’s nearly two-decade journey stands as proof that Vietnam can fully own its clean energy future.
“From solar cells to a clean energy ecosystem – SolarBK doesn’t just generate power, it ignites Vietnam’s vision of a sustainable future.”
