2. Project Background and Environmental Imperative
The Dongguan manufacturing plant, characterized by its curved corrugated iron roofing, presented unique challenges for solar integration. Traditional systems often fail to address thermal management and structural limitations on non-standard roof geometries. NSPV's engineering team prioritized environmental impact assessment, conducting a comprehensive site survey to evaluate load-bearing capacity, solar incidence angles, and regional climate patterns. This analysis revealed that the existing roof structure required a bespoke design to support PV panels while maximizing energy efficiency and minimizing carbon emissions. The project aligns with China's "Dual Carbon" goals, aiming to reduce industrial emissions through renewable energy adoption.

3. Structural Design: Independent Load-Bearing Framework and Thermal Management
To address structural limitations, NSPV developed an independent load-bearing framework using high-strength galvanized steel supports anchored to the building's structural columns. This design minimizes stress on the original roof while ensuring optimal panel alignment for maximum solar capture. Modular spacing between panels facilitates natural convection cooling, reducing roof surface temperatures by 15-20°C and decreasing cooling loads in adjacent production areas. This thermal management strategy not only protects the roof substrate but also enhances PV cell performance by maintaining optimal operating temperatures, directly contributing to reduced carbon emissions through improved energy efficiency.
