According to EnergyTrend, Lians Technology announced on April 16 that the first multi-slice module rolled off the production line at its Meishan base. This marks the official commissioning of Lians Technology’s world’s first GW-level production line for 765W high-power Heterojunction (HJT) multi-slice modules.
At present, the 765W high-efficiency HJT multi-slice modules have entered a phase of stable mass production and are capable of bulk delivery. The multi-slice technology has achieved large-scale commercial deployment in the high-power HJT product segment.
In terms of product features, the 765W module adopts self-developed 0BB silver-coated copper cells from Lians Technology, integrated with multi-slice technology and high-density packaging processes. It boasts a maximum bifaciality of 95% and a mass-production efficiency exceeding 24.63%. The product effectively reduces costs including mounting structures, combiner boxes, cables and land occupancy, optimizes Balance of System (BOS) and Levelized Cost of Electricity (LCOE), and is suitable for diversified scenarios such as large-scale ground-mounted PV power stations, commercial & industrial distributed PV projects and PV-plus integrated applications.
As compiled by EnergyTrend, driven by rapid iteration of PV technologies in recent years, multi-slice technology has become a core efficiency improvement pathway for leading enterprises, and 2026 is expected to be the breakout year for quad-slice products.
In view of the current industry development progress, major PV manufacturers have completed the layout of multi-slice technologies, with obvious differentiation in their mass production schedules.
- Lians Technology: Achieved stable mass production of GW-level quad-slice 765W modules, with bulk efficiency above 24.63% and bifaciality of 95%, taking a leading position in the industry.
- TCL Zhonghuan: Focuses mainly on triple-slice technology, with its T5 Pro series under bulk mass production.
- JA Solar:Its DeepBlue 5.0 series covers triple-slice and quad-slice products with power ratings of 645–670W, currently in small-batch mass production.
- Jinko Solar:Its TigerNeo 3 is quad-slice TOPCon modules with a maximum power of 670W. Official production roll-off was announced in November 2025, and the products are now in stable mass production and bulk delivery.
- Tongwei: Its TNC 3.0 adopts quad-slice design, has been publicly unveiled and shipped in small batches, with large-scale mass production scheduled for Q3 2026.
- Astronergy:Mainly promotes quad-slice high-power modules, which are currently in small-batch trial production.
- Trina Solar: Its Vertex 3rd generation products adopt quad-slice + high-density packaging, with a maximum TOPCon power of 760W. The modules are in small-batch trial production and are expected to achieve large-scale mass production in Q3 2026.
- Risen Energy: Its early PERC triple-slice products have basically withdrawn from the mainstream market, and the company is currently focusing on high-efficiency N-type technology routes.
Overall, multi-slice technology has extended from TOPCon to mainstream N-type technology routes including HJT and BC, and become a standard configuration for high-power modules.
With leading enterprises continuously accelerating the layout and construction of multi-slice production lines, large-scale mass production will drive yield improvement and cost reduction. Multi-slice modules are expected to shift from a high-end option to an industry mainstream standard.
The commissioning of Lians Technology’s GW-level HJT multi-slice production line not only sets new records for the power rating and mass production scale of HJT modules, but also verifies the commercial feasibility of the combination of HJT and multi-slice technologies. It provides a new direction for overall cost reduction and efficiency improvement across the industry, and the HJT multi-slice segment is poised to become a key focus of technological competition in the next industry phase.
