Jinko Solar Tiger Neo JKM435N-54HL4R-B

Jinko Solar is the world's largest solar panel manufacturer by shipped volume, and the Tiger Neo is their flagship N-Type TOPCon residential platform. The JKM435N-54HL4R-B variant delivers 435W at 21.77% module efficiency in a 1762×1134mm 108-cell (6×18) all-black format with black frame and black backsheet.

Tiger Neo cells degrade at roughly 0.40%/year versus 0.55%/year for Mono PERC; the 30-year performance warranty (industry-leading at this tier) reflects that lower degradation rate, ending at 87.4% of nameplate output after a 1% first-year drop.

Who it suits

The default choice for UK installers looking for a current-generation N-Type TOPCon panel from a brand with maximum installer familiarity. Tiger Neo is what most installers will quote first if you don't specify otherwise.

What I'd watch for

The Tiger Neo range includes many variants across efficiency, watt rating, and frame style — confirm with your installer that you're getting the all-black 435W version (vs the silver-frame, half-cut, or higher-watt-but-bigger variants). Jinko's 25-year product warranty for this 54HL4R-B series in Europe is competitive, paired with the 30-year linear power warranty.
