550W High Efficiency Solar Panels with 5400PA Wind and Snow Load Resistance

Five power ratings from 540W to 560W with additional -V variants, flexibly matching various project capacities and budgets.

P-type monocrystalline cells with a 144 half-cut (6x24) layout deliver module efficiency of 20.90% to 21.68% for superior energy conversion.

3.2mm high-transmittance, AR-coated low-iron fully tempered glass with textured surface ensures higher light transmission and stronger aging resistance.

Max system voltage of 1000/1500VDC (IEC) enables longer strings, reducing cable and combiner box usage for lower balance-of-system costs.

The whole module is certified to withstand 5400Pa front and 2400Pa back maximum static test loads, delivering excellent wind and snow resistance.

With a Pmax temperature coefficient of only -0.35%/C, power loss is minimized at high temperatures-ideal for hot-climate installations.

Annual degradation of only 0.55%, with 98% power retention at year 12 and 84.8% at year 25, ensuring stable long-term returns.

Positive power tolerance of 0~+3%; IP68 junction box with TUV 1x4.0mm2 cable; certified to IEC 61215 / IEC 61730 and ISO 9001 / ISO 14001 / ISO 45001 for smooth global market access.
