Pallet of 36 LONGi Hi-MO X10 Explorer 490 W monofacial solar modules 17.64 kWp
Full pallet of 36 LONGi modules rated 490 W, for a total of 17.64 kWp. Buying the complete pallet costs less than buying single modules and is the usual choice for a complete residential or commercial system.
The LONGi LR7-54HVH-490M belongs to the Hi-MO X10 Explorer family and is currently one of the highest efficiency solar panels available in a residential format: 490 W from 1800 × 1134 mm, which works out at 24.0 % module efficiency. That step up in performance comes from the HPBC 2.0 back-contact cell built on TaiRay wafers: moving every electrical contact to the rear of the cell removes the shading caused by front busbars and recovers active area, for a direct power gain within the same footprint.
The module is monofacial with a single 3.2 mm glass and weighs only 21.6 kg, which makes handling and mounting considerably easier on residential pitched roofs and small commercial systems. The back-contact architecture also delivers a real advantage in low light conditions and under partial shading, because it cuts resistive losses and limits hot-spot formation; the temperature coefficient of -0.26 %/°C, among the best in its class, keeps summer losses down. The black frame and the uniform front surface round off a product aimed at anyone looking for maximum power per square metre without compromising on looks, with a 15-year product warranty and a 30-year linear performance warranty.
Key features
24.0 % efficiencyOne of the highest figures in the residential class: 490 W from under 2.05 m², ideal where roof space is tight.
HPBC 2.0 back-contact cellEvery contact sits on the rear: no front busbars, no shading on the cell and more active area exposed to the light.
TaiRay waferThe proprietary LONGi wafer improves silicon uniformity and cell mechanical strength, reducing the risk of microcracks.
Only 21.6 kgThe low weight and the single 3.2 mm glass make carrying the panel onto the roof straightforward and reduce the dead load on the structure.
Temperature coefficient -0.26 %/°CThe back-contact cell runs cooler and loses less power on hot days than conventional TOPCon modules.
15 + 30 year warrantyFifteen years on materials and workmanship, thirty years of additional linear warranty on power output.
