LONGi, a Chinese module manufacturer, has introduced the Hi-MO X10 module specifically crafted for deployment within the distributed solar sector.
Introduced at the Rolex Shanghai Masters tennis tournament, the module incorporates LONGi’s second-generation hybrid passivated back contact (HBPC) cells. With a peak power conversion efficiency of 24.8%, a maximum output of 670W, and featuring LONGi’s TaiRay silicon wafers, this module sets a new standard in solar technology.
LONGi chairman Zhong Baoshen expressed confidence, stating, “We are convinced that BC technology will emerge as the leading technology in crystalline silicon cells, encompassing both bifacial and monofacial designs. Going forward, a substantial portion of LONGi’s product portfolio will adopt the BC technology route.”
“Our goal is to advance this extensively acknowledged technology platform, known for its high compatibility and exceptional durability, across a broader spectrum of applications and markets.”
Utilizing LONGi’s HPBC 2.0 cells, the Hi-MO X10 modules boast a maximum conversion efficiency of 26.6%, as per LONGi’s assertions. These cells represent an advancement from the company’s initial back contact cells introduced in 2022. Additionally, the module features a 0BB structure, eliminating busbars on the back and grid lines on the front, a design element that LONGi states enhances the module’s overall power output by 5W.
The modules feature LONGi’s “soft breakdown design,” a feature the company highlights as ideal for the distributed solar sector. This design ensures that in scenarios where shading or temperature fluctuations impact a section of a panel, common in distributed installations where obstructions like trees or buildings may cast shadows, the current is rerouted through alternative internal pathways within the cell.
According to LONGi, the design results in a reduction of power loss by more than 70% when compared to tunnel oxide passivated contact (TOPCon) products. The company also stated that redirecting power can aid in cooling a module during periods of excessive heat, potentially decreasing hotspot temperatures by up to 28%.
After introducing a back contact module achieving a power conversion efficiency of 22.3% at the Intersolar 2024 event in Munich, Germany, LONGi has now revealed this latest development. The company highlighted that it had delivered nearly 80GW of cells, wafers, and modules in the initial six months of the year. However, despite this strong performance, LONGi reported that its total revenue for the first half of the year was lower compared to the corresponding period in 2023.
