Strategic procurement partner for ultra-high-efficiency n-type heterojunction solar cells and modules – operated by Area Solar.
Dinto Solar Co., Ltd. is a China National-Level High-Tech Enterprise specialising in the R&D, manufacturing, and commercialisation of ultra-high-efficiency n-type heterojunction (HJT) solar cells and modules.
Established in 2017 by the Central Research Institute of State Power Investment Corporation (SPIC) – the world's largest photovoltaic, renewable, and clean energy company. Dinto Solar operates an R&D centre in Nanchang and manufacturing facilities in Longgang and Suining, with a planned annual HJT capacity of 15 GW.
Dinto.solar is operated by Area Solar, serving as a strategic procurement partner for Dinto Solar. We provide local support, tailored PV solutions, and direct access to Dinto's world‑class HJT technology for utilities, EPCs, and developers across Europe.
HJT technology combines crystalline silicon with ultra-thin amorphous silicon layers, delivering superior efficiency, reliability, and sustainability.
24.47% module champion efficiency. HJT technology combines crystalline silicon with ultra-thin amorphous silicon layers, minimising energy losses and unlocking superior conversion performance.
Industry-leading -0.24%/°C temperature coefficient. Higher bifaciality (90%+) with 2-5% greater bifacial energy yield than TOPCon. ≤9.7% total degradation over 30 years.
Innovative butyl sealant (PIB) + dual-glass construction ensures exceptional moisture resistance. Light conversion film enhances UV resistance. Copper gridlines deliver superior microcrack resistance.
Only 4 core process steps (vs. 10+ for TOPCon/BC). Low-temperature processing below 200°C. Silver-free copper metallisation cuts carbon footprint to just 2.56% of silver.
We provide high-quality HJT modules and cells with proprietary intellectual property and industry-leading performance.

Tailored solutions for utility-scale, distributed, offshore, and vertical PV applications.
Utility-scale solar plants are turning deserts, plains, and mountains into highly efficient "green energy factories." Dinto Solar's HJT modules stand out with an exceptional temperature coefficient of -0.24%/°C and excellent low-light performance.
Dinto Solar's distributed energy solutions feature compact, efficient modules with high investment returns, emerging as a model for supporting energy transition and helping businesses and households reduce costs and increase efficiency.
Dinto Solar's offshore HJT modules are engineered with high-reliability encapsulation, including PIB sealing and corrosion-resistant glasses. Along with the inherent benefits of HJT technology, our offshore solutions provide stable, reliable returns over a 30-year lifespan.
Dinto Solar's HJT modules, with bifaciality up to 95%, offer substantial rear-side energy gains. Vertical modules feature a unique dual-peak generation curve that aligns perfectly with peak-valley electricity pricing, boosting plant revenues.
Dinto Solar brings together leading HJT talent with a highly capable R&D team led by industry authorities, including national-level overseas talent who serves as Chief Expert in photovoltaics for SPIC. Core team members each possess more than 15 years of experience across the photovoltaic and semiconductor industries.
Dinto Solar maintains sustained and strategic investment in research and development, having undertaken nearly ten municipal-, provincial-, and ministerial-level science and technology projects. The company has applied for and been granted more than 100 high-quality invention patents, holds over 30 proprietary technologies, and has multiple patented technologies recognized as internationally leading.
As China's first company with fully independent production capability for copper-metalized heterojunction (C-HJT) modules, Dinto Solar continues to explore solutions to further enhance solar cell efficiency, delivering superior and sustainable value to customers.
Dinto Solar implements comprehensive quality inspection across every stage of production, with certifications from globally recognized third-party organisations.
Including ISO 9001, ISO 14001, ISO 45001, TÜV, PID, PCCC, CGC, and CE certifications.
HJT technology requires only four core process steps, significantly fewer than the more than ten steps required for TOPCon and BC technologies.
90-110μm wafers minimise thermal damage and eliminate high-temperature diffusion, significantly reducing silicon consumption and energy usage.
Only 4 core process steps vs. 10+ for TOPCon and BC technologies. Higher yield, lower energy consumption, and improved process controllability.
Copper delivers electrical conductivity and mechanical strength comparable to silver, yet is 1,600 times more abundant and costs only one-tenth as much.
