JinkoSolar 420W Tiger Neo N-Type TOPCon 54 Cell All Black JK03 Solar Panel
JinkoSolar 420W Tiger Neo N-Type TOPCon 54 Cell All Black JK03 Solar Panel
The JinkoSolar Tiger Neo is an N-type mono-crystalline solar panel. It delivers 21.5 % module efficiency from a 1,722 × 1,134 mm frame.
About the JinkoSolar Tiger Neo range
Tiger Neo is JinkoSolar's mainstream n-type range, rated by the manufacturer for lower first-year and annual degradation than p-type modules and for better output in the low, diffuse light that makes up much of the UK's annual irradiance.
At 1,722 × 1,134 mm it is a residential-format module, sized to fit the rafter spans and roof planes of a standard UK house. The black frame and dark cells keep the array visually quiet on a front-facing roof.
Why installers specify this panel
- −0.30 %/°C power temperature coefficient — output falls away more slowly as the modules heat up through the middle of the day.
- All-black appearance — a black anodised frame and dark cells, for domestic roofs where the array has to be discreet.
- 0 to +3 % power tolerance — every module is sorted to meet or beat its 420 W nameplate rating.

Array sizing
Each panel covers 1.95 m². A 4 kWp array needs 10 of them (4.20 kWp over about 20 m²). A 6 kWp array needs 14 of them (5.88 kWp over about 27 m²). Each module weighs 22.0 kg.
About JinkoSolar
JinkoSolar is one of the world's largest module manufacturers. Its Tiger Neo range is built on n-type TOPCon cells with the company's HOT 3.0 process, which it rates for lower LID and LeTID degradation, better low-light output and an anti-PID guarantee, with certified salt-mist and ammonia resistance for coastal and agricultural sites.
