Turns sunlight into current with an efficiency of 21.76%: 425 W at STC, 320 W at NOCT and a 30-year power warranty.
A photovoltaic panel turns sunlight directly into electric current, without moving parts and without noise. This model uses N-type cells with TOPCon passivation, a newer generation of solar cell that loses less of its power when it heats up in the sun. The panel is made of cells cut in half, a construction trick that reduces internal losses and limits the effect of a shadow falling on a single row. In practice, you install it once and then it produces electricity for years on end, with an occasional wash.
Each panel gives 425 W under laboratory conditions (STC) and 320 W at the real operating temperature on the roof (NOCT, 45 degrees C) - the difference is normal with any panel and that is why the temperature coefficient matters. Here Pmax falls by only 0.30% for each degree above the reference, so on scorching days you lose less than with a classic PERC panel. The power tolerance is exclusively positive, 0 ~ +3%, so the panel delivered may not be below 425 W. Ten pieces mean 4.25 kW of installed power, about 19.5 m2 of roof and 22 kg to handle for each panel. The warranty is 12 years for the product and 30 years linear for the power, with a degradation of 0.40%/year and a minimum of 87.4% of the nominal power after 30 years.
STC: Pmax 425 Wp, Vmp 31.70 V, Imp 13.41 A, Voc 38.30 V, Isc 14.15 A; coefficients -0.30 %/degree C (Pmax), -0.25 %/degree C (Voc), +0.046 %/degree C (Isc), NOCT 45 +/- 2 degrees C, operating range -40 ... +85 degrees C. Laminate of 108 half-cells 6x18 with SMBB, front glass tempered 3.2 mm anti-reflective low-iron, frame of anodised aluminium alloy, IP68 junction box, cables 1x4.0 mm2 with 400 mm (+) and 200 mm (-). The -V suffix dimensions the module for 1500 V DC, with a maximum string fuse of 25 A; the string length is checked on Voc at the minimum temperature of the site, with the coefficient of -0.25 %/degree C. IEC 61215:2016 and IEC 61730:2016 certifications, declared resistance to salt mist and ammonia, Hot 2.0 technology against LID/LeTID degradation and anti-PID resistance, mechanical load 5400 Pa snow / 2400 Pa wind, packaging 36 pcs/pallet.
Suitable for a house with a pitched roof or a small company that wants a balanced panel, with small heat losses and a long power warranty.

Specifications confirmed from the manufacturer's datasheet
JKM425N-54HL4-V is part of the Jinko Tiger Neo 54HL4-(V) series (410-430 W), built on N-type monocrystalline cells with TOPCon passivation and SMBB (super multi-busbar) technology. The laminate has 108 half-cells arranged 6x18, tempered front glass of 3.2 mm with an anti-reflective coating and a low iron content, a frame of anodised aluminium alloy and an IP68 junction box. The cables are 1x4.0 mm2, with lengths of 400 mm (+) and 200 mm (-).
At STC the module delivers 425 Wp, with Vmp 31.70 V, Imp 13.41 A, Voc 38.30 V and Isc 14.15 A, respectively 320 Wp at NOCT (800 W/m2, 20 degrees C ambient, wind 1 m/s). The power tolerance is exclusively positive, 0~+3%. The temperature coefficients are -0.30 %/degree C for Pmax and -0.25 %/degree C for Voc, values typical of N-type technology, which reduce the losses on hot summer days compared to a classic PERC module. Hot 2.0 technology limits LID/LeTID degradation, and the manufacturing process ensures anti-PID resistance.
The module is certified to IEC 61215:2016 and IEC 61730:2016, withstands 5400 Pa of snow load and 2400 Pa of wind load and has declared resistance to salt mist and ammonia. The version with the -V suffix is dimensioned for 1500 V DC strings, which allows longer strings in commercial installations; the maximum string fuse is 25 A. The standard packaging is 36 pcs/pallet, 936 pcs in a 40'HQ container.
More energy from the same roof area: 600 W from a single module, at 23.2% efficiency, with the contacts moved to the back for a fully active front face.
Fewer parts and faster installation for the same power: 615 W per module, at 23.8% efficiency, in a panel of 27 kg and 2278x1134x30 mm.
455 W and 22.8% efficiency in a 21.5 kg panel, with cells without metal contacts on the front and low losses in heat.
The front of the panel has no metal stripes: 450 W, 22,6% efficiency and only 21,5 kg, with good behaviour under partial shading.
