Sidel Beijing installs rooftop solar system to grid, advancing decarbonization goals

CHINA – Sidel has successfully completed grid integration of a rooftop solar photovoltaic system at its Beijing plant, marking a major milestone in its sustainability journey and reinforcing its leadership in green manufacturing within the packaging equipment industry.

With an installed capacity of 2.1 megawatts (MW), the solar system is expected to generate approximately 4.39 million kilowatt-hours (kWh) of clean electricity annually.

This will cover around 60% of the plant’s daily electricity needs, while cutting CO₂ emissions by an estimated 2,452 tonnes per year.

Using a ‘self-consumption with surplus feed-in’ model, the system prioritizes on-site energy use, with 35% of the generated energy fed back into the municipal grid through smart power networks.

This approach maximizes energy efficiency and resource utilization, aligning with China’s broader ‘Dual Carbon’ strategy of peak carbon emissions and carbon neutrality.

The system features LONGi’s Hi-MO7 high-efficiency solar modules, offering 615W panel power and a conversion efficiency of 23.1%, some of the highest in the industry.

Beyond the solar initiative, Sidel’s Beijing plant integrates sustainability into every aspect of its operations, earning certifications such as ISO 50001:2018 Energy Management, ISO 14064-1:2018 Zero Carbon Factory, and 5-Star Green Supply Chain Management under GB/T standards.

Designated as a Beijing-certified Green Factory, the site has implemented a suite of environmental innovations, including a smart Energy Management System, Building Automation System, and equipment frequency retrofits.

These measures, along with low-temperature distillation for wastewater treatment, optimized water recycling systems, and LED lighting upgrades, have collectively slashed resource use while enhancing workplace comfort.

The plant also offers on-site EV charging stations to promote low-emission commuting.

“Our new PV system not only reduces our operational carbon footprint but also reinforces Sidel’s commitment to sustainable industry transformation,” said Li Yonghon, Director of Sidel Beijing Plant.

“We will continue to invest in innovative technologies to help build a greener future.”

Sidel has committed to a 73% reduction in Scope 1 and 2 emissions by 2030 from a 2019 baseline, having already achieved 64% of that goal by 2024.

Since 2022, all Sidel plants globally have run on 100% renewable electricity, with the Beijing solar project serving as a powerful symbol of this ambition.

Looking ahead, the company plans to explore energy storage solutions and smart energy management systems to transform the Beijing plant into a fully integrated urban green energy hub.
