LG 400W Mono NeonH Plus Black V6 Solar Panel
LG 400W Mono NeonH Plus Black V6 Solar Panel
The LG NeON H+ Black is an Monocrystalline N-type, 9 multi-wire busbar (CELLO) solar panel. LG's CELLO cell design replaces flat busbars with twelve thin round wires, reducing shading losses across the cell surface. It delivers 20.4 % module efficiency from a 1,880 × 1,042 mm frame.
About the LG NeON H+ Black range
NeON H+ is LG's all-black residential module, using twelve thin round wires in place of flat busbars so the face reads as solid black from ground level.
At 1,880 × 1,042 mm it is a residential-format module, sized to fit the rafter spans and roof planes of a standard UK house.
Why installers specify this panel
- −0.33 %/°C power temperature coefficient — output falls away more slowly as the modules heat up through the middle of the day.
- Reinforced load rating, 6,000 Pa front / 5,400 Pa rear — for high-snow and high-wind locations.
- Long-dated warranty — 25-year product warranty and 25-year linear output warranty: minimum 98.5 % in year 1, maximum 0.33 % annual degradation thereafter, minimum 90.6 % at year 25.
- 0 to +3 % power tolerance — every module is sorted to meet or beat its 400 W nameplate rating.

Warranty and certification
25-year product warranty and 25-year linear output warranty: minimum 98.5 % in year 1, maximum 0.33 % annual degradation thereafter, minimum 90.6 % at year 25. Certified to IEC 61215-1/-1-1/-2:2016, IEC 61730-1/2:2016, OHSAS 18001, ISO 9001, ISO 14001, ISO 50001, IEC 62701:2011 severity 6 (salt mist), IEC 62716:2013 (ammonia).
Array sizing
Each panel covers 1.96 m². A 4 kWp array needs 10 of them (4.00 kWp over about 20 m²). A 6 kWp array needs 15 of them (6.00 kWp over about 29 m²). Each module weighs 19.7 kg.
About LG
LG Solar was the module arm of LG Electronics, and LG Electronics remains the warrantor behind these panels. The NeON range was tested to double the intensity the IEC standard requires, and took the EuPD Research Top Brand PV seal from European installers.
