When evaluating the JA Solar 630W photovoltaic panel size, professionals typically find dimensions averaging 2,238mm × 1,134mm × 35mm. This N-type heterojunction (HJT) module represents the industry's shift toward larger-format solar solutions, achieving 22.8% conversion efficiency through 144 half-cut cell technology.
Unlike conventional 72-cell panels measuring 2.0m × 1.0m, the JA Solar 630W utilizes advanced double-glass encapsulation and zero-gap interconnection to maximize surface area utilization. Recent field tests show 8-12% higher energy yield compared to PERC modules in low-light conditions.
Commercial installations using these panels demonstrate 15% reduction in BOS costs through:
A recent 5MW solar farm in Arizona achieved 4.3kWh/W annual yield using this configuration, outperforming traditional designs by 9%. The bifacial design (70% bifaciality factor) contributed additional 18% energy gain from ground reflectance.
While current JA Solar 630W panel dimensions push practical handling limits, emerging robotic installation systems enable deployment of even larger formats. The industry anticipates 700W+ modules exceeding 2.4m length within 24 months, maintaining similar efficiency gains through TOPCon and tandem cell advancements.
