The Longi 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).
About Longi Solar
LONGi’s PERC module won the first prize in energy yield simulation in 2017 and 2018, and the first prize in outdoor energy yield of monofacial module in 2019 conducted by TÜVRheinland.
The PERC cell has a passivated rear side and a laser grooving process, which significantly improves the cell efficiency.
