SolarBK Commissions Its First Commercial Solar + BESS Project at Sedo Vinako

On August 14, 2026, at the Sedo Vinako factory in Dong Yen Industrial Cluster, Duy Xuyen Commune, Da Nang City, SolarBK and Sedo Vinako held the Commercial Operation Date (COD) ceremony for a rooftop solar project integrated with a Battery Energy Storage System (BESS), featuring 2.2 MWp of solar capacity and 2.3 MWh of energy storage.

This is the first Solar + BESS project implemented by SolarBK to enter commercial operation under the ESCO model, marking a further step from rooftop solar toward integrated energy solutions for the manufacturing sector. The energy challenge for exporters is evolving

Sedo Vinako, a member of South Korea’s Sedo Camping Group, manufactures outdoor textile products and participates in the supply chains of international brands including IKEA, ADEO, and Walmart.

For manufacturers operating within global supply chains, energy management is increasingly shaped by multiple priorities: controlling production costs, reducing emissions, increasing the share of renewable energy, and meeting sustainability requirements from customers and business partners. Against this backdrop, alongside increasing the use of clean energy, businesses are paying greater attention to how on-site renewable electricity can be utilized more effectively. With solar power, generation and factory demand do not always coincide, creating a growing need for more flexible energy storage and dispatch.

At Sedo Vinako, BESS has been integrated to store solar electricity that is not immediately consumed and make it available for production at more appropriate times. This helps increase solar self-consumption, reduce electricity purchased from the grid, and improve the flexibility of the factory’s energy operations.

Solar + BESS under the ESCO model

With 2.2 MWp of solar capacity and 2.3 MWh of BESS, the project extends the ESCO model from rooftop solar to an integrated energy solution incorporating battery storage. The addition of BESS also changes the way a C&I energy project is approached. Beyond installed solar capacity, system design and operation must take into account the factory’s load profile, solar generation patterns, storage capacity, and actual electricity demand. The question is therefore no longer simply how much solar capacity can be installed, but how generation, storage, and load can be coordinated to make more effective use of available energy.

At the COD ceremony, Kim Byung Tae, Director of Sedo Vinako, said that after nearly two years since the first phase of cooperation, the actual operating performance of the solar system provided an important foundation for Sedo Vinako to continue working with SolarBK and move forward with Solar + BESS.

“We highly appreciate SolarBK’s support throughout our cooperation, from the initial phase to the current project. Our decision to move forward with Solar + BESS builds on the results of our partnership and the performance demonstrated through actual operations. Sedo Vinako expects the new system to enable more efficient and flexible use of renewable energy, and we look forward to continuing our long-term cooperation with SolarBK,” Mr. Kim said. According to Nguyen Thi Ngoc Quynh, Deputy CEO of SolarBK, the Sedo Vinako project goes beyond adding a storage component to an existing solar system; it also introduces a deeper level of integration between technology and the factory’s actual operational requirements.

“What matters is not simply adding storage capacity, but how solar generation, BESS, and the factory’s load can be coordinated to better match its actual operations. This is the first Solar + BESS project implemented by SolarBK to enter commercial operation, and the practical experience gained here will provide an important foundation for us to continue developing energy solutions tailored to the specific characteristics and needs of each business,” Ms. Quynh said.

Building on proven operational performance

The Solar + BESS project represents the next phase of cooperation between Sedo Vinako and SolarBK. In late February 2024, an approximately 1.62 MWp rooftop solar system entered operation at the factory. According to project data, the system helps Sedo Vinako save approximately VND 2 billion in electricity costs annually, generate around 2,300 I-RECs per year, and reduce approximately 1,600 tonnes of CO₂ emissions annually. Building on this foundation, Sedo Vinako expanded its energy solution by integrating BESS. SolarBK’s cooperation with South Korean businesses in Vietnam has also extended to PNS Chun, another member of Sedo Camping Group at VSIP Quang Ngai Industrial Park, and Cell Bio Human Tech, where an approximately 1.22 MWp solar system has been commissioned at its manufacturing facility in Central Vietnam.

While these projects differ in scale and load profile, they highlight the increasingly important role of actual operating data as businesses consider the next steps in their energy investments.

Expanding energy management at the factory level

As part of the COD ceremony, SolarBK also presented 3,000 Renewable Energy Certificates (RECs) to Sedo Vinako, supporting the recognition of renewable energy use and the company’s broader sustainability objectives.

Solar power generates renewable electricity on-site; BESS adds the ability to store and dispatch that electricity according to demand; while RECs provide a mechanism for recognizing its renewable energy attributes. Together, these three components illustrate how energy management at the factory level is expanding from generating clean electricity to managing how energy is generated, stored, used, and recognized.

The commissioning of the Sedo Vinako project therefore marks more than SolarBK’s first commercial Solar + BESS project. It also provides practical operating data on the integration of battery storage with rooftop solar in a real manufacturing environment.

As C&I businesses increasingly seek to balance energy costs, operational efficiency, and emissions reduction goals, operational data from Sedo Vinako will provide a practical basis for further evaluating the role of Solar + BESS at manufacturing facilities with similar load profiles. Every manufacturing facility has its own load profile and energy requirements. SolarBK works with businesses to assess their needs, design, and implement tailored energy solutions — from rooftop solar to Battery Energy Storage Systems (BESS) — with the aim of improving energy efficiency and supporting long-term emissions reduction goals.
