Dinto Solar has been awarded a 200 MW supply contract for heterojunction (HJT) solar modules for a large-scale residential distributed photovoltaic project developed by Shandong Huadian. Following contract signing, the company rapidly initiated module deliveries, which are now progressing in a stable and continuous manner.
The project spans residential rooftops across 16 cities in Shandong Province and adopts 715 W and 720 W n-type HJT modules. All modules are supplied in compliance with stringent technical and metrological requirements defined by the China Institute of Metrology, reflecting elevated standards for power output verification, performance consistency, and manufacturing quality in the residential PV segment.
After the contract was awarded, Dinto Solar completed technical validation and production ramp-up within a short timeframe. Initial shipments were launched within one week, enabling construction activities to proceed on schedule. Module deliveries are being executed in scheduled batches to support simultaneous installation across multiple locations.
The 200 MW Shandong Huadian project underscores the growing role of HJT technology in residential and distributed photovoltaic applications, where higher module power and efficiency and long-term reliability are increasingly critical selection criteria.
Project execution is supported by Dinto Solar’s integrated R&D and manufacturing platform. The company operates a centralized R&D center in Nanchang, together with smart manufacturing facilities in Longgang and Suining, forming a scalable production system for advanced n-type technologies. Dinto Solar has a planned annual capacity of 15 GW of HJT cells and modules, designed to support reliable, large-volume supply.
In parallel, Dinto Solar continues to advance the commercial-scale application of silver-free HJT processes, reducing precious metal usage while maintaining high conversion efficiency and long-term module reliability. Looking ahead, the company will further promote the industrialization of HJT technology and advance next-generation solutions, including copper metallization and HJT-perovskite tandem, supporting the continued evolution of high-efficiency photovoltaic systems.
