The "PV Code" on the Tip of the Tongue! CENTER INT & LONGi Empowers Qianhe Food to Unlock Green Brewing

In the hometown of Su Dongpo, light and shadow empower industry. The 7.2MW distributed photovoltaic power generation project tailored by CENTER INT and LONGi for Qianhe Food was successfully connected to the grid in Meishan, Sichuan, achieving a deep integration of traditional condiment brewing workshops with green solar energy. As a vivid practice implementing the national requirement to "promote the use of green technology equipment for energy conservation and carbon reduction in traditional industries," this project, with its "PV + Food" innovative model, provides a feasible and replicable new paradigm for the green transformation of traditional manufacturing, further demonstrating the technological leadership and scenario adaptation capabilities of CENTER INT & LONGi in the distributed PV field.

Qianhe Food, a leading enterprise  the condiment sector for over two decades, upholds the mission of "crafting Chinese flavors with ingenuity." While pursuing product quality upgrades, it actively responds to the national "Dual Carbon" strategy, anchoring itself in the direction of green and low-carbon transformation. This PV project is a key measure for the enterprise to practice green production concepts, and CENTER INT & LONGi, their and one-stop service capabilities in the BIPV (Building Integrated Photovoltaic) field, became the core partner for project implementation.

To adapt to the stringent production standards and rooftop usage requirements of a food enterprise, CENTER INT & LONGi adopted parallel-laid installation on the sloping surfaces of color steel sheet roofs and flexibly adjusted angles using professional supports on concrete roofs. This ensured both the efficiency and stability of the PV system while not interfering with daily factory production and hygiene control, perfectly aligning with the core demands of the food brewing industry: "stable power supply and strict hygiene standards."

Addressing the diverse structural characteristics of different buildings in the Qianhe Food factory area, such as the koji-making workshop, refining workshop, and glass bottle warehouse, CENTER INT & LONGi tailored a composite solution combining BIPV and BAPV, achieving efficient adaptation between green energy and industrial spaces. The project covers approximately 45,000 square meters of factory rooftops, utilizing high-performance PV modules paired with efficient inverters and transformers to construct a stable power generation system with a DC side installed capacity of 7.2MW and an AC side capacity of 5.95MW. It connects to the grid at the 10kV voltage level, operating under the "self-consumption, surplus grid feed-in" model to maximize energy value.

The successful grid connection of the project achieves a dual breakthrough in environmental and economic benefits. Environmentally, the project's average annual power generation can reach 5.4186 million kWh. Calculated based on a standard coal consumption rate of 300g/kWh for coal-fired power plants, it can save approximately 1,625.58 tons of standard coal annually. Over its 25-year lifecycle, it will save a total of 40,639.5 tons of standard coal, equivalent to planting about 247,000 trees. Simultaneously, it can reduce CO2 emissions by a total of 111,100 tons, with zero water consumption and wastewater discharge throughout the process, reducing the environmental footprint of the enterprise from the source.

In terms of economic benefits, the project, centered around "self-consumption," effectively reduces Qianhe Food's dependence on purchased industrial electricity. The total expected power generation over 25 years is 135.4652 million kWh, continuously generating stable income for the enterprise throughout its long operational. Additionally, feeding surplus power into the grid can further broaden its revenue channels.

CENTER INT & LONGi consistently focus on the green transformation needs of industrial scenarios, leveraging the dual drivers of "technology + service" to provide customized PV solutions for clients across different industries. This collaboration with Qianhe Food not only solves the协同 challenge between the high stability power demand and low-carbon transformation for a food brewing enterprise but also provides a replicable and scalable practical experience for the deep integration of PV technology with traditional manufacturing.

In the future, CENTER INT & LONGi will continue to the field of photovoltaic integration, using more advanced technology and to help more traditional enterprises embark on the dual-optimal path of "green production + quality upgrading," injecting a continuous stream of solar-powered momentum into the realization of China's "Dual Carbon" goals and the high-quality development of the manufacturing industry.
