Hi-MO X10 - back-contact modules for commercial and industrial rooftops

Renewable Energy Sector · Solar PV (panels, inverters, mounting)

A back-contact solar panel with a built-in Shading Optimizer that bypasses only the shaded cells rather than whole strings. LONGi states it reduces localized overheating by up to 28%, lowers operating and hotspot temperatures by up to 29°C compared with conventional panels, and cuts power output loss by 70% compared with TOPCon modules. Versions include Anti Glare, Light Design, Class A Fire Resistant and Anti Dust.

• Shading Optimizer bypasses only shaded cells
• Up to 28% less localized overheating; hotspot temperature down by up to 29°C
• 70% lower power loss under shading than TOPCon
• Anti-glare, fire-resistant, light and anti-dust versions
