Dinto Solar has successfully transitioned Heterojunction (HJT) technology from R&D labs to large-scale global commercialization. With massive investments and record-breaking orders, the company is reshaping the solar landscape.

  • Dinto Solar invested over $59 million in HJT R&D by the end of 2025.
  • The company holds over 120 patents and specializes in both silver and copper-metallized HJT.
  • Order volumes grew by over 200% year-on-year in 2025.
  • Future goals include achieving cell efficiencies exceeding 30% via tandem technology.

BEIJING: The solar energy industry is witnessing a paradigm shift as Dinto Solar celebrates nine years of specialized focus on Heterojunction (HJT) technology. Founded in 2017 under the Central Research Institute of the State Power Investment Corporation (SPIC), the company has successfully bridged the gap between laboratory innovation and massive-scale industrial deployment.

Dinto Solar’s trajectory is defined by its massive commitment to R&D. By the end of 2025, the firm had funneled over US$59 million (RMB 400 million) into HJT research—representing more than 25% of its total revenue. This strategic financial discipline has yielded a portfolio of over 120 patents, positioning Dinto as a rare manufacturer capable of mass-producing both silver-metallized and copper-metallized (C-HJT) cells and modules.

Mastering the 'Golden Triangle' of Solar

In the solar manufacturing sector, the 'golden triangle' refers to the simultaneous achievement of high efficiency, low cost, and long-term reliability. Dinto Solar has addressed this through its flagship G12-132 HJT module. This ultra-high-power module delivers 760 W at 24.47% efficiency, offering superior lifetime returns for utility-scale and residential customers alike.

Dinto Solar’s ability to optimize the manufacturing process while maintaining extreme efficiency is setting a new benchmark for the global PV industry.

Market Dominance and Rapid Scaling

The commercial momentum for Dinto Solar has been explosive. In 2025, the company secured over 2 GW of orders, marking a staggering 200% year-on-year increase. This momentum has continued into 2026, with the company winning major bids under China Datang's 1 GW framework and being shortlisted for POWERCHINA's 3 GW procurement project.

BozokMedia analysis shows that Dinto Solar's competitive edge also lies in its operational agility. For a 200 MW project for China Huadian in Shandong, the company managed to complete the entire cycle—from technical review to first-batch delivery—within a single week in 2025, demonstrating unparalleled supply chain integration.

Historical Background

When Dinto Solar began its journey in 2017, HJT technology was considered a niche, pre-commercial concept. While many competitors focused on standard PERC technologies, Dinto made a long-term bet on the future of high-efficiency cells. Today, that bet has resulted in a planned 15 GW HJT footprint and deployments across more than 30 countries.
