In recent years, the preferred wafer size in the photovoltaic industry has shifted from 182 mm to larger 210/210R dimension. This change reflects a drive toward higher module power, greater production efficiency, and reduced system costs. Curious how Huasun optimized wafer size to shape heterojunction (HJT) solar cell performance that outperform others? Let’s dive in!
01: Expanded Cell Area
Huasun has successfully adopted larger wafers across the product portfolio, enabling greater active area and improved solar absorption for higher efficiency.
Combined with the ultra-high module bifaciality and excellent temperature coefficient of HJT solar modules, they offer a superior solution for PV projects in hot climates, including desert environments.
02: Next-Gen Module Power
The adoption of larger solar wafers enables the production of modules with higher output power. Huasun’s Himalaya series 210-132 HJT solar module currently delivers 730 W, with mass production power expected to reach 760 W by the end of 2025.
Meanwhile, the Everest series, featuring 210R wafers, is also expected to achieve a deliverable power of 660 W with its 210R-132 HJT module.
03: Optimizied Container Utilization
The introduction of 210 and 210R wafers has reshaped solar module dimensions, significantly improving container utilization. This optimization lowers logistics costs, reduces transport-related emissions, and allows Huasun to focus more on technology and quality.
04: Stronger Module Reliability
Combined with Huasun’s advanced encapsulation, the module reliability is significantly enhanced for broader PV applications. Huasun’s HJT modules are now widely used in buildings, transforming rooftops, balconies, fences, and facades into highly efficient clean energy sources.
