LONGi LR7-54HVH 480 W

LONGi LR7-54HVH 480 W solar panel, N-type TOPCon, 108 cells. An N-type cell with TOPCon passivation degrades less in its first year than a P-type cell and loses less power in the heat — which in Portugal, on a roof in August, is what separates real-world performance from catalogue performance. Supplied and installed by us, with the design, mounting structure, cabling and registration of the UPAC (the self-consumption production unit) with the DGEG, the Portuguese energy authority, all included in the quote.
