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.
