Culture In Practice
[ 02 | MILESTONES ]
From Solar Manufacturer to Global ESS Partner
Since 2008, SUNPAL ESS has grown from a solar PV manufacturer in China into a global battery energy storage supplier serving EPCs, distributors, wholesalers, and project developers across 150+ countries. Each milestone reflects stronger manufacturing capacity, smarter ESS technology, and reliable delivery for commercial, industrial, and utility-scale clean energy projects.
Founded in Hefei, China
SUNPAL ESS began in Hefei with a clear mission: make reliable solar power more accessible worldwide. Early investment in PV manufacturing, quality control, and supply-chain management built the foundation for long-term growth as a solar energy manufacturer and clean energy supplier.
Independent R&D and Manufacturing Expansion
SUNPAL ESS expanded R&D and production capabilities in Jiangsu, strengthening photovoltaic technology, module manufacturing, and engineering support. This stage also prepared the company for future battery storage, BESS system design, and integrated solar-plus-storage solutions.
Global Market Growth
SUNPAL ESS extended its international distribution network across 80+ countries, delivering solar PV and energy storage solutions for residential, commercial, and industrial customers. By 2019, cumulative PV installations exceeded 5 GW and BESS deliveries surpassed 1 GWh, supported by overseas subsidiaries in North America and Europe.
Automated Manufacturing Upgrade
With growing global demand for renewable energy products, SUNPAL ESS upgraded automated production lines and intelligent factory systems. Annual PV manufacturing capacity reached 12 GW, improving product consistency, lead time control, wholesale supply capacity, and global project delivery reliability.
Accelerating Energy Storage Development
SUNPAL ESS launched a 5 GWh C&I energy storage production line and expanded its European presence with a Frankfurt office. The company strengthened ESS cabinet, battery container, EMS, BMS, and system integration capabilities to support EPC procurement, commercial storage projects, and renewable energy deployment.
Digital Energy Base and Global Recognition
Phase I of the 10 GWh Digital Energy Base began operation, increasing SUNPAL ESS’s battery energy storage manufacturing capacity and large-scale delivery strength. SUNPAL ESS ranked among the global Top 5 in user-side energy storage shipments and expanded its Yixing battery production base with 2.5 GWh annual capacity.
Certified Technology Leadership
SUNPAL ESS achieved key certifications and technical recognition for proprietary EMS, high-voltage BMS, and low-voltage BMS technologies, including CE, UL standard, and Cape Laboratory recognition. Today, SUNPAL ESS continues to deliver customized PV and ESS solutions for global buyers seeking reliable cost, capacity, and long-term project support.
