Wuxi Dailing Vacuum Technology's 2.2MW rooftop photovoltaic power station was successfully connected to the grid. Solartale' structural reinforcement and waterproofing Tech. to ensure 25 years of safe operation.

May 30, 2026, Wuxi Dailing Vacuum Technology rooftop distributed photovoltaic power generation project has successfully connected to the grid. The project is developed by Wuxi Solartale PV Tech. Co., Ltd.The project, undertaken by Wuxi Solartale, utilizes the unused space of the factory's cement roof and corrugated

steel roof. The total installed capacity is 2.2MW, employing JA Solar's 620W high-efficiency monocrystalline photovoltaic modules and multiple

GoodWe 50kW string smart inverters. The system operates stably and has excellent power generation efficiency, marking another large-scale benchmark

case for distributed photovoltaic applications in Wuxi's industrial and commercial sectors.

Project Highlight 1: Upgrading Baosteel's zinc-aluminum-magnesium roofing to achieve

lifespan synchronization.

In response to the aging potential problems of the owner's original corrugated steel roof, the Wuxi Solartale team proactively replaced all the old corrugated steel roofs at the beginning of the project construction, selecting Baosteel Zinc Aluminum Magnesium Sheet As a new roofing material.

Zinc-aluminum-magnesium (ZAM) roofing sheets possess excellent corrosion resistance, self-healing capabilities, and high strength, effectively addressing

the common acid and alkali corrosion challenges faced by industrial plant roofs. After replacement, the new roof's lifespan perfectly matches the 25-year lifespan

of the photovoltaic power station, ensuring the owner's safety and well-being throughout the power station's operational lifespan. none The roof needs‍ to be

replaced twice.‍ This completely solves the pain point of "power stations can't wait for rooftops" in industrial and commercial distributed photovoltaic systems.

Project Highlight 2: Purlin reinforcement treatment reduces load and leakage risk.

Based on the roof replacement, the Solartale team also addressed the roof...The purlin structure has been fully reinforced. By inspecting and evaluating the

existing steel structure, the density and connection strength of the purlins were increased in a targeted manner, which significantly improved the load-bearing

capacity of the roof.

This measure provides dual protection:

• Reduce load riskThe reinforced purlin structure can stably bear the long-term load of photovoltaic modules and support systems,

  eliminating safety hazards caused by structural fatigue.

• Reduce the risk of water leakage By optimizing the purlin layout and roof fixing method, damage to the waterproof layer caused by structural deformation

  is effectively avoided, and the risk of roof leakage is greatly reduced.

Project Highlight 3: Special installation solution to overcome the problem of chronic leakage in

cement roofs

The cement roof in this project has Long-term chronic leakage The problem is that conventional waterproofing repair methods are insufficient to

completely resolve the issue. To address this technical challenge, the Solartale team adopted Special installation scheme Without damaging the original

roof structure, the potential for leakage in cement roofs was successfully resolved by adopting a BIPV (Building Integrated Photovoltaic) installation method and waterproofing treatment.

This solution not only ensures the long-term stable operation of the photovoltaic power station but also fundamentally eliminates the owner's concerns about

roof leaks. Specific technical details can be found in the project site construction video.

The combination of these three technical measures fully embodies Soalrtale's professional philosophy of "not only building power stations, but also ensuring

building safety" in industrial and commercial distributed projects.

Significant energy conservation and emission reduction benefits

After the power station is connected to the grid, the average annual power generation is expected to reach 2.42 million kWh. Based on the coal consumption

standards for thermal power plants, approximately 870 tons standard coal can be saved annually.

Reduce carbon dioxide emissions by approximately 2410 tons. This is equivalent to planting approximately132,000 trees trees per year.

The energy conservation and emission reduction benefits are significant.

From the perspective of the entire life cycle, this power station It can generate approximately 60.5 million kilowatt-hours of electricity over 25 years.

The cumulative savings of standard coal is nearly 21,800 tons Cumulative reduction of carbon dioxide emissions is approximately 60,300 tons.

This long-term, stable output of green electricity not only brings continuous electricity cost savings to enterprises, but also helps the country

achieve its "dual carbon" goals through concrete actions.
