LONGi X10 LR7 54HVH 475/490M

Back-Contact. Record yield. Quiet roof.

LONGi's flagship Back-Contact platform. By moving every busbar to the rear of the cell, X10 delivers ~24 % efficiency, a uniform jet-black face with zero finger lines, and a 490 W rating that fits roofs other 475 W panels can't.

BACK-CONTACT CELLS

Front-side photons. No metal in the way.

Every electrical contact moves to the rear of the cell. The result is a uniformly black face that captures more of the light hitting your roof — and a panel that looks like part of the architecture, not bolted on top of it.

PERFORMANCE

More yield per square metre. Every season.

Higher cell efficiency means more kWh from the same roof. X10's low temperature coefficient (−0.26 %/°C) keeps the meter spinning through Australian summer afternoons.

30-YEAR WARRANTY

Designed for the next two roof replacements.

First-year degradation under 1 %, then a linear curve that guarantees ≥ 88.85 % output at year 30. Backed by LONGi's tier-1 manufacturer warranty and Megawatt's local service network.
