The SP-M450 is a 144 half-cell monocrystalline module for residential and commercial rooftops. Nine busbars and half-cell cutting reduce resistive losses, while the anodised frame and dual EL tested cells withstand 5400 Pa snow and 2400 Pa wind loads. Every panel is flash-tested and packed on a 31-piece pallet with corner protection.SP-M450 是面向住宅与工商业屋顶的 144 半片单晶组件。九主栅与半片切割降低电阻损耗，阳极氧化边框配合双 EL 检测电池片，可承受 5400 Pa 雪压与 2400 Pa 风压。每块组件均经功率测试，31 片一托并带护角包装。
The panels arrived with flash data that matched our own measurements, and the UN38.3 papers cleared customs without a delay.
We ordered a mixed container of batteries, inverters and controllers to test the range, and everything worked together on the first try.
