LONGi has announced the launch of its latest product, the Hi-MO X6 Max series, at its Jiaxing factory. The LONGi Hi-MO X6 Max series entered mass production in the current quarter, with a complete transition for all mainstream products expected by Q3 2024.
The LONGi Hi-MO X6 Max series follows the industry-wide consensus on module size standards reached by nine manufacturers and subsequent agreement on wafer size standards by six manufacturers in July and August 2023 respectively. The launch also marks LONGi’s first large-scale transition to rectangular silicon wafers (wafer size: 182.2×191.6mm; module size: 2382×1134mm).

The LONGi Hi-MO X6 Max product family is an upgrade in three dimensions: technology, size and product.
- Technology: First-time integration of the new TaiRay Inside and HPBC high-efficiency cell technologies
- Size: First transition after the standardization of dimensions.
- Product: Inheriting product design such as Anti-Dust and Anti-Humidity and Heat from the Hi-MO X6 series, but also the introduction of the Artist (Ultra Black) on to the distributed PV market
Standard dimensions explained
The lack of unification on wafer and module sizes had long been a contentious issue in the PV industry. Standardization on sizes simplifies the supply chain, reduces material waste and minimizes design errors during installation, facilitating easier maintenance and management.
On July 7, 2023, LONGi and eight other companies agreed on new standard dimensions for rectangular silicon wafers and modules. Subsequently, on August 8, 2023, LONGi, along with five other companies, reached a consensus on the standardized dimensions for 72-cell rectangular silicon wafers (rectangular wafer size:182.2mm x191.6mm; rectangular wafer diagonal: 262.5mm).
The Hi-MO X6 Max series exemplifies this progress. LONGi’s recently launched TaiRay wafer and the breakthrough in mass-production of its self-developed HPBC technology has led to the creation of the new series, which integrates M11 dimensions (182.2mm×191.6mm) with TaiRay Inside and HPBC cell technologies.
According to Lv Yuan, head of the LONGi Product and Solution Centre, the standardized dimensions of Hi-MO X6 Max maximize customer benefits and reduce costs for engineering and material partners. The optimized dimensions also enhance container utilization during transportation, once again saving costs.
Taking the 72-cell version as an example …
- The new product can reduce transportation costs by $0.61/kW compared with the conventional Hi-MO X6 module, improving use of 40HC containers by 4.4% to achieve 98.5% container utilization.
- Due to power enhancement, the BOS cost on the system installation side is also reduced by 3.57% (about $4.16/kW) when compared with the equivalent mainstream power grade (585W vs. 615W).
- Customer revenue is also enhanced when compared to using 210R wafer based modules, Hi-MO X6 Max using M11 wafers with lower current, which can effectively reduce loss of current transmission cabling by 9% and increase power generation revenue by 0.1%.
