Prime Vinh Phuc Phase 2: Solving the Engineering Challenges Behind a Solar Project

For many manufacturers, investment returns remain the primary consideration when evaluating rooftop solar. However, once the financial case is established, another question often becomes even more critical: can the system be installed without disrupting production, compromising safety, or affecting the structural integrity of a factory roof that remains in continuous operation?

In reality, most commercial and industrial rooftop solar projects are installed while factories continue normal operations. What differentiates an EPC contractor is not simply the ability to install a solar system on an active facility, but the capability to execute the project safely, minimize operational disruption, and effectively manage technical risks throughout the entire implementation process.

These are precisely the priorities guiding the implementation of Prime Vinh Phuc Phase 2, SolarBK's latest rooftop solar project. Construction officially commenced on 12 June 2026, and the project has now entered the photovoltaic module installation stage. With a total installed capacity of over 1.13 MWp, the system is expected to generate more than 1.25 million kWh of clean electricity annually while reducing approximately 824 tonnes of CO₂ emissions each year. Beyond lowering electricity costs, the project will contribute to improving the factory's overall operational efficiency and sustainability performance.

However, what is visible on site today represents only a small part of the work behind the project.

Prime Vinh Phuc Phase 2 follows the successful completion of Prime Vinh Phuc Phase 1, which SolarBK delivered and commissioned in February 2025. The stable performance of the first system, combined with the quality of project execution, laid the foundation for Prime's decision to once again entrust SolarBK with the next phase.

In industrial rooftop solar projects, being selected to implement subsequent phases is one of the strongest indicators of an EPC contractor's engineering capability, construction quality, and ability to meet the stringent requirements of an operating manufacturing facility.

Prime Vinh Phuc is the oldest manufacturing company within the Prime Group and home to its very first ceramic tile factory. After nearly two decades of development, the facility now has an annual production capacity of 15 million square metres of ceramic tiles, supported by modern production lines and rigorous quality management standards.

For a manufacturing plant operating continuously at this scale, every activity carried out on the roof must be carefully planned to ensure project progress without interfering with production.

This also explains why the project's greatest challenge is not lifting solar modules onto the roof, but executing the installation on a roofing system that has been in service for many years. Every engineering solution must prioritize preserving the existing roof structure while minimizing the risk of future defects throughout the system's operating life.

For manufacturers, maintaining the integrity of the roof is a critical engineering requirement. Any post-installation water ingress, however minor, can lead to repair costs, production interruptions, or even affect product quality. As a result, one principle guided the project from start to finish:

Project schedule should never come at the expense of the factory's existing assets.

With this philosophy, SolarBK approached the project not simply as a solar installation, but as a comprehensive risk management exercise for an operating manufacturing facility. From site surveys, structural assessments, and mounting point calculations to construction planning and on-site execution, every step was designed to protect existing assets, maintain uninterrupted production, and ensure reliable system performance throughout its lifecycle. Before installation began, SolarBK's engineering team conducted multiple site surveys, evaluated the roof structure, developed detailed construction methodologies, optimized structural connection points, and completed the technical documentation required by the client. Although much of this work remains invisible to most observers, it plays a decisive role in ensuring the system's safety, quality, and long-term reliability.

Beyond the engineering requirements, the project also presented significant construction management challenges. The nature of ceramic tile manufacturing creates a unique working environment that demands rigorous control over safety procedures, personnel, equipment, and construction processes before work can begin.

At the same time, construction activities were carried out alongside legal and regulatory procedures while requiring close coordination with multiple departments within the client's organization. This demanded not only strong on-site execution but also effective project management across engineering, procurement, legal compliance, construction, and safety to keep the entire project on schedule.

Having successfully completed Phase 1 also gave SolarBK a significant advantage during Phase 2. The project team was able to anticipate site-specific risks more effectively, tailor construction methodologies to actual conditions, and coordinate seamlessly with the factory's operational teams throughout implementation.

That confidence is built on proven execution capability.

In 2025 alone, SolarBK completed 38 industrial solar projects with a combined installed capacity of 205 MWp across multiple industries and locations throughout Vietnam. These figures represent more than project scale, they demonstrate the company's ability to manage complex construction activities, control quality, and deliver projects reliably under diverse operating conditions.

As more manufacturers invest in rooftop solar to optimize energy costs, strengthen competitiveness, and achieve their ESG objectives, expectations of EPC contractors are evolving.

Today, an EPC partner is no longer evaluated solely by installed capacity. Increasingly, value is measured by the ability to execute projects safely within operating factories, manage technical risks, protect existing assets, and ensure reliable long-term system performance.

Prime Vinh Phuc Phase 2 reflects this industry shift.

As each solar module is installed, SolarBK is delivering more than a new renewable energy system. It is reinforcing manufacturers' confidence that increasingly complex industrial energy projects can be delivered safely, efficiently, and to the highest engineering and project management standards.

That commitment continues to define SolarBK's role in supporting Vietnam's transition toward a cleaner, more sustainable industrial future.
