Two N-type TOPCon panel ranges that account for half of UK domestic installs. Equivalent technology — small differences in warranty, weight and stock matter.
LONGi LR5 and Jinko Tiger Neo both use N-type TOPCon cells, both warrant 25 years on output, both are MCS-certified. LONGi has wider UK installer distribution and a small first-year output edge. Jinko is around 5% cheaper at wholesale and has a marginally better temperature coefficient. On a typical 4 kWp install the lifetime difference is under £200 — pick on installer stock, not panel.
