The Longi LR4 Hi-MO X is a mono PERC solar panel featuring a shingled layout. “Shingle” solar panels are modules comprised of multiple thin overlapping solar cells.
Available in capacities up to 405W (72-cell) and 355W (60-cell), the Hi-MO X offers module efficiencies of between 19.3% and 20.3% for the 72-cell series and 19.1% – 20.3% for the 60-cell.
Both the 60- and 72-cell Hi-MO X have a temperature coefficient of Pmax of -0.37 %/°C. This refers to how much power a solar panel loses for every °C above 25°C (panel temperature, not ambient air temperature).
