Hi-MO X10
440–470W, HPBC 2.0 back-contact cells for the cleanest all-black finish and the highest efficiency in the range — LONGi’s flagship premium residential module.
Hi-MO 9
450–470W, HPBC 2.0 back-contact modules built for performance-critical residential and light commercial sites wanting flagship-tier output.
Hi-MO 6
410–445W, TOPCon / HPBC cells covering budget-conscious residential and commercial installs without giving up LONGi’s 25yr/30yr warranty.
Why LONGi is a low-risk choice
- Manufacturing scale. As the world's largest solar panel producer, LONGi has deep supply-chain redundancy — useful for warranty confidence over a 25-year horizon.
- Slow degradation. Roughly 1% first-year degradation, then about 0.35–0.4% per year after — panels keep producing close to nameplate output for decades.
- A tier for every budget. Hi-MO 6 covers value-conscious installs; Hi-MO X10 and Hi-MO 9 target premium residential and performance-critical sites.
- Clean, all-black finish. HPBC 2.0 moves contacts to the rear, giving flagship models the same uniform look as top-tier back-contact competitors.
Good fit for
- Buyers who want a globally dominant, bankable brand
- Budget-sensitive installs (Hi-MO 6) through to premium (X10)
- Installers wanting one supplier across multiple project tiers
