LONGi and Trina are two of the largest panel manufacturers in the world and both appear constantly on Perth residential quotes. The current ranges take slightly different routes to the same place: LONGi's Hi-MO uses a back-contact cell design, Trina's Vertex N uses N-type i-TOPCon. Here is a fair, spec-led comparison for WA roofs, and where the genuine differences sit.
Quick answer
Warranty length and the all-black option separate these two more than day-to-day output does. Pick LONGi if you want LONGi's back-contact cell design and the quote comes in keener. Pick Trina if you are keeping the home long term and want the longer performance-warranty term, or you want a widely-stocked all-black panel. Both ranges qualify for federal STCs in Perth (STC Zone 3); there's no separate WA panel rebate.
