What I noticed
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 22.27% module efficiency in a 1762×1134mm 54-cell 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.
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). The 12-year product warranty is shorter than premium brands offer.
