June 2026 — Suzhou Dexin Chip Technology Co., Ltd. successfully connected its 1.5MW rooftop distributed photovoltaic (PV) project to the grid. The project was undertaken by Wuxi Martin Green Solar Technology Co., Ltd. (Martin Solar), utilizing the plant's extensive TPO waterproof membrane roof for PV module installation. The core technical solution — TPO waterproof membrane paired with a dedicated PV mounting system — completely resolves the industrial roof leakage challenge, establishing a new industry benchmark for TPO roof solar installations.
Project Background
Suzhou Dexin Chip Technology Co., Ltd., located in the Advanced Manufacturing & International Trade Zone of Suzhou Industrial Park, is a high-tech enterprise specializing in high-end power semiconductor R&D and manufacturing. The company's new facility features a large-area TPO waterproof membrane roof — ideal conditions for building a large-scale distributed PV station.
However, installing solar on TPO roofs presents unique technical challenges: How can PV mounting brackets be reliably secured without compromising the waterproof layer? How can the mounting system remain stable throughout the 25-year plant lifecycle without affecting roof waterproofing? These requirements demand an exceptionally well-engineered solution.
Technical Solution: TPO-Specific Mounting System
To address the unique characteristics of the TPO waterproof roof, Martin Solar's technical team conducted multiple site surveys and feasibility studies before selecting a TPO-specific PV mounting system that resolves the waterproof-versus-structural dilemma at its root.
Core Technology Highlights: The solution employs TPO-specific clamps + aluminum alloy rails. The clamps are fusion-bonded to the TPO membrane via hot-air welding, forming an integrated waterproof structure. The mounting system has undergone rigorous pull-out testing, with individual anchor points meeting all design load requirements — ensuring stability and reliability even under extreme weather conditions such as typhoons.
Compared to conventional mounting solutions, the TPO-specific system offers the following advantages: Zero Penetration — No damage to the TPO membrane; full waterproof integrity preserved. Hot-Air Welded Fixation — Clamps and membrane fused as one; seal quality comparable to the native waterproof layer. 25-Year Service Life — TPO material resists aging and chemical corrosion, matching the full lifecycle of the PV plant. Superior Wind Uplift Resistance — System tested in wind tunnels, capable of withstanding typhoons of Category 12 and above.
Precision Construction Process
Throughout construction, the Martin Solar team strictly adhered to TPO roof installation standards — from substrate preparation and layout marking, through clamp welding and rail installation, to module fixing. Each step featured mandatory quality hold-points to ensure compliance.
The construction team adopted a modular installation workflow, breaking traditional procedures into standardized units to significantly boost installation efficiency. Meanwhile, dedicated safety supervisors were stationed on site, ensuring all elevated workers were secured with safety harnesses and that work areas were clearly marked with safety signage — guaranteeing comprehensive construction safety.
Successful Grid Connection — By the Numbers
After months of intensive construction and commissioning, the Suzhou Dexin 1.5MW rooftop PV plant officially connected to the grid in June 2026. The plant is operating stably, with all performance indicators meeting or exceeding design expectations.
The plant generates approximately 1.65 million kWh annually. Based on standard coal consumption for thermal power, this saves about 660 tonnes of coal and reduces CO₂ emissions by roughly 1,645 tonnes each year — equivalent to planting approximately 90,000 trees annually. Over its 25-year lifecycle, the plant will generate a cumulative ~41.25 million kWh, delivering sustained electricity cost savings for the enterprise while actively contributing to China's national "Dual Carbon" goals.
Client Endorsement
During the grid-connection acceptance process, the relevant manager of Suzhou Dexin Chip Technology Co., Ltd. gave high praise to Martin Solar's construction quality and technical solution: "From TPO roof protection to bracket installation, the professional team at Martin Solar demonstrated exceptional technical competence and a strong sense of responsibility. Since grid connection, the plant has been running steadily, and the roof waterproofing remains intact. We are very satisfied."
