DUAL GLASS

Two faces. One panel.

Rear-side gain can provide up to 20–25 % additional energy generation in suitable installation conditions.

LOW-LIGHT

First panel up. Last panel down.

An optimised front-surface texture and BC-cell architecture extend useful generation into early morning, late afternoon, and overcast conditions — where most rooftops actually live.

PROVEN FIELD RECORD

GW-scale deployments. Bankable.

Multi-gigawatt of LONGi X10 already on roofs and in solar farms across five continents. Tier-1 bankability, tier-1 warranty, tier-1 service.
