Tiếng ViệtMany industrial facilities in Vietnam operate on factory buildings that have been in use for decades. This presents a significant challenge when deploying rooftop solar power systems, as the structural integrity of these roofs often no longer meets the load-bearing requirements of standard system designs. The Grand Gain project (2,400 kWp) is a prime example, where INS Energy was entrusted with addressing this complex technical issue.
The entire system was deployed across six rooftops, none of which individually met the criteria to support the full intended capacity. Meanwhile, the investor aimed to maximize energy efficiency, ensure operational safety, and comply with stringent technical standards.
Weak Roofs Are a Familiar Challenge – But Never an Easy One
To ensure optimal capacity without overloading the structures, INS Energy redesigned the solar panel system based on three core principles: load reduction, even distribution, and leveraging structurally sound roofs. Specifically, weaker roof areas were assigned a lower panel density and reinforced mounting frames, while structurally stronger sections were prioritized for high-efficiency panels.
An asymmetrical mounting approach was implemented to balance the load between both sides of the roof, minimizing the risk of sagging or imbalance. In parallel, the engineering team selected lightweight, durable aluminum frames to reduce load while maintaining wind and vibration resistance in line with industry standards. In addition to addressing the rooftop challenge, INS Energy also upgraded the entire capacitor cabinet system – a critical component in maintaining the power factor (PF) required by EVN. Outdated capacitor cabinets were replaced, and the connection points were redesigned to ensure optimal synchronization of electrical output from the distributed inverter clusters to the main cabinet.
INS Energy: Turning Challenges into Advantages
Rather than chasing maximum capacity, INS Energy focuses on designing systems that reflect real conditions and actual needs – ensuring compatibility with structural constraints to deliver safe, stable, and long-term performance. This approach has been highly regarded by investors, particularly as safety regulations and technical inspections for construction are becoming increasingly stringent.
The Grand Gain project is a clear demonstration that there is no one-size-fits-all formula for rooftop solar installation – only the most suitable solution for each specific situation. INS Energy set itself apart through the technical solution developed by its in-house engineering team.
With extensive experience handling projects involving weak roofs, curved surfaces, limited load capacity, and outdated electrical infrastructure, INS Energy is steadily reinforcing its reputation for professionalism and adaptability across every project. The Grand Gain rooftop solar power project once again proves that when the right solution comes first, strong results follow.
Above all, INS Energy prioritizes the unique conditions of each facility to propose technically sound, cost-effective solutions that fully comply with EVN standards. With a team of seasoned engineers, INS Energy is a trusted partner for businesses transitioning toward green manufacturing and sustainable energy savings.
