In response to China's national "Dual Carbon" goals, Liuzhou Hengjia Tower Manufacturing Co., Ltd. has successfully completed a rooftop solar photovoltaic retrofit project at its main production facility in Rong'an County, Guangxi. The initiative marks a significant step toward clean energy adoption in the region's industrial sector, showcasing how traditional manufacturing can embrace green transformation and energy efficiency.
Liuzhou Hengjia Tower Manufacturing Co., Ltd. is a key player in the metal product and wind power equipment manufacturing industry. Recognizing the importance of sustainable growth, the company has partnered with a professional solar energy solutions provider to install a high-performance rooftop PV system on its steel-structured factory buildings — aligning its energy use with the "Dual Carbon" strategic consensus.

The PV system was installed using specialized clamps on color steel tile rooftops, eliminating the need for drilling or structural penetration. This mounting method preserves the integrity of the existing roof while ensuring the photovoltaic panels are securely and precisely angled to maximize energy generation.
Upon completion, the rooftop PV system underwent standard typhoon-grade resistance testing. Under a wind pressure equivalent of 1000N, the clamps and roof materials showed no signs of damage, cracks, or deformation—a critical safety assurance in typhoon-prone regions of Southern China.
The solar panels serve a dual purpose — generating renewable electricity while acting as a sun-shading layer that reduces indoor heat load. This helps lower air conditioning energy consumption during peak seasons, contributing to overall energy savings.
| ▲ Installed Capacity | 2500 KWp |
| ▲ Daily Effective Power Generation Time | 4H |
| ▲ Daily Effective Power Generation | 10000 Kwh |
| ▲ Power Consumption | Photovoltaic power generation, 80%-100% full consumption by the investor |
| ▲Investment & Return Cycle | 5 years |
| ▲ Usable Life | 20 years |
This solar retrofit directly supports China's national decarbonization agenda, while also fulfilling Guangxi's provincial energy transformation roadmap — positioning Hengjia as a benchmark in green industrial practices.
Idle rooftop space is now transformed into a high-yield clean energy asset, increasing the property's utility and long-term value.
With the majority of electricity generated used onsite, the company significantly reduces its reliance on grid power — leading to lower operational costs and greater supply stability.
The adoption of renewable energy enhances the company's ESG performance and boosts its eco-friendly brand reputation in both domestic and international markets.
Since 2021, Rong'an County has accelerated its clean energy infrastructure with wind power, centralized PV, distributed rooftop PV, and energy storage projects. The successful commissioning of the Hengjia rooftop solar project contributes to this momentum — offering a replicable model for other industrial enterprises seeking to transition toward green, low-carbon operations.
