Rooftop Solar Boosts Factory Renewable Energy Share
Sidel’s Beijing Plant’s rooftop solar photovoltaic (PV) system has now achieved full grid connection
Thousands of PV panels now form a blue armour-like array across the facility, gleaming under the sunlight. This milestone green energy project injects new momentum into Sidel’s sustainable operations, marking a solid step forward in the company’s decarbonisation journey and setting a new benchmark for green transformation in the industry.
Solar PV system powers low-carbon operations as ‘Green Energy Hub’ launched
With an installed capacity of 2.1 MW, Sidel Beijing’s solar system is expected to generate 4,394,700 kWh annually – meeting 60% of the plant’s daily operational electricity needs and reducing CO₂ emissions by 2,452 tonnes per year.
Through the innovative ‘self-consumption with surplus feed-in’ model, 35% of the clean energy generated will be fed back into the municipal grid via smart power networks after fulfilling on-site demand. This enables optimised allocation and efficient utilisation of green energy, transforming every ray of sunlight into sustainable power.
As a signature project to China’s ‘Dual Carbon’ strategy implementation, the installation features industry-leading LONGi Hi-MO7 high-efficiency modules with 615W panel power and a top-tier conversion efficiency of 23.1%.
Multi-pronged approach to building a model green factory
Since establishing operations in Beijing in 2008, Sidel Beijing Plant has embedded sustainability into its core strategy. Continuous environmental investments and innovations culminated in 2025 certifications including ISO 50001:2018 Energy Management System; ISO 14064-1:2018 Zero Carbon Factory; and GB/T 39257-2020 / GB/T 33635-2017 5-Star Green Supply Chain Management.
As a Beijing-certified Green Factory, Sidel’s environmental efforts go far beyond solar energy, encompassing an intelligent Energy Management System (EMS) and Building Automation System (BAS) for precise energy control; a retrofit programme for equipment frequency conversion to reduce consumption; low-temperature distillation technology to minimise effluent from acid-wash passivation; continuous optimisation of water recycling systems saving hundreds of tonnes annually; upgraded lighting that cuts power use while improving employee comfort; and on-site EV charging stations to promote greener commuting and lower carbon footprints.
Global green commitment, local implementation
Environmental stewardship remains a Sidel a core value, developing innovative solutions to reduce its footprint. The Group has an ambitious target (73% reduction in Scope 1 & 2 emissions versus 2019 baseline) and has already achieved 64% of reduction in 2024. Since 2022, all Sidel plants globally operate on 100% renewable energy, with the Beijing solar project being a tangible manifestation of this commitment.
“Building a beautiful Earth requires concrete corporate action. This PV system not only slashes our operational carbon footprint but demonstrates Sidel’s unwavering commitment to green manufacturing. We will continue exploring innovative technologies to advance sustainable industry development,” comments Li Yonghon, Director, Sidel Beijing Plant.
Standing beneath the solar panel canopy, we see not just clean energy flowing through these silent sunlight harvesters, but Sidel’s resolute journey toward sustainability. Future plans include exploring energy storage solutions and smart energy management to transform the plant into an urban green energy hub.
