Solar for Solar
LONGi supports the "Solar for Solar" business model. While creating low-cost clean energy products for the world, the company uses clean energy and green manufacturing practices in its operations whenever possible. Since 2015, LONGi has located its operations in Yunnan, China, and Kuching, Malaysia, to utilize the abundant local hydropower resources to provide clean energy for its facilities. LONGi plans to integrate solar power plants with pumped storage in areas that feature significant elevation differences and abundant sunlight, creating an industrial model for using solar.
