Tiếng ViệtIn rooftop solar projects, roof preparation is a critical foundation that directly impacts long-term system performance. At the H.A VINA Tire rooftop solar project (Tay Ninh), roof coating and waterproofing works are being systematically implemented prior to PV system installation.
Proactive Roof Treatment Before System Installation
The project is located at Lots 47-1, 47-2, 47-3, D11 Road, Phuoc Dong Industrial Park, Tay Ninh Province—an area with high solar irradiance, ideal for rooftop photovoltaic (PV) development. However, industrial factory roofs are typically exposed to harsh environmental conditions, leading to potential degradation, leakage, or corrosion over time.
Therefore, prior to solar installation, comprehensive roof inspection, reinforcement, and surface treatment are carried out to ensure compliance with technical requirements. This is a crucial step to minimize operational risks in the long term.
Roof Coating and Waterproofing – A Long-Term Risk Mitigation Strategy
According to the EPC contractor, roof coating and waterproofing are not merely maintenance tasks but strategic components of the overall project. One of the major risks in rooftop solar systems is roof leakage after full installation. In such cases, the entire system—including PV modules, mounting structures, and cabling—may need to be dismantled for repair. This results in operational downtime and significant additional costs.
By addressing these issues upfront, the project eliminates potential risks, ensuring stable system operation without major interventions throughout its lifecycle.
Strengthening Roof Structure and Extending Asset Lifespan
In addition to waterproofing, roof coating enhances the durability of the factory roof. The protective layer helps mitigate environmental impacts such as rain, UV exposure, humidity, and metal corrosion, thereby extending the roof’s service life.
For solar projects with an expected lifespan of 20–25 years, maintaining long-term structural integrity of the roof is essential. Substandard roofing conditions can directly affect system safety, especially under extreme weather conditions.
Investing in roof reinforcement from the outset is therefore a cost-effective strategy to protect both the building and the PV system.
Optimizing Solar System Performance
Beyond structural considerations, roof quality also influences system performance. A stable, leak-free roof ensures that the mounting system and PV modules remain securely fixed, maintaining correct tilt angles and installation positions as per design. This contributes to maximizing solar irradiance capture and overall energy yield. Conversely, poor roof conditions—such as structural instability, vibration, or water ingress—can reduce system efficiency and equipment lifespan.
Ensuring Construction Standards from the Initial Phase
The implementation of roof coating and waterproofing at the H.A VINA project reflects a comprehensive and professional EPC approach. Rather than focusing solely on system installation, the contractor prioritizes foundational conditions, from roof structure to overall technical standards. This approach aligns with the broader trend in the renewable energy sector, where projects increasingly demand higher standards in quality, durability, and long-term operational reliability.
