LONGi · solar panel for utility-scale plants
LONGi Hi-MO 9 solar panel, 635–670 W
LONGi's flagship for ground mounts and tracker fields: HPBC 2.0 cells with all contacts on the back, module efficiency up to 24.8% and dual glass. The front face carries no gridlines — all current is collected from the rear, so there are simply no shading losses from the grid.
Most watts per hectare
Up to 670 W per module at 24.8% efficiency. On a ground mount that means fewer piles, less cable and fewer rows for the same capacity.
75% bifaciality
The rear face picks up reflected light: on light ground, concrete and snow the yield gain is substantial.
Handles heat
A −0.26%/°C temperature coefficient, among the best in the industry. At midday the module loses less than a classic TOPCon panel.
0.35% degradation per year
At least 88.85% of rated power guaranteed at year 30. First-year degradation under 1%.
Shipped from stock in Krasnodar across Russia. Send us the array size and grid phase configuration — our engineer will check the inverter selection and string layout before dispatch.
