Our Jiaxing production lines also manufacture under NDA for BNEF Tier-1 brands — meaning you can OEM this exact module with your company name on the nameplate, your chosen frame color, your J-box labeling. Entry point 2 containers; full custom program at 50 MW annual volume. Tier-1 wrap available for bankability-required PPA projects.
HJT heterojunction cell technology — our highest-efficiency module.
Industry-leading temperature coefficient. Best performer for hot climates above 35°C.
Highest bifaciality in the JUSTSOLAR lineup. Maximum rear-side energy capture.
Lower annual degradation (0.35%/yr) = 88.8% output at year 25.
The JUSTSOLAR 740W HJT represents our highest-performance module, using heterojunction cell technology (amorphous silicon + crystalline silicon) for industry-leading efficiency and the best-in-class temperature coefficient in the lineup. Temperature coefficient of -0.24%/C (vs -0.30%/C for TOPCon) means HJT maintains more of its rated power in hot climates — critical for Middle East, North Africa, and tropical installations where ambient temperatures regularly exceed 40°C. 85% bifaciality factor (vs 80% for TOPCon) captures more rear-side energy. Zero Light-Induced Degradation (LID) and lowest annual degradation (0.35%/yr vs 0.40%/yr TOPCon). Premium price point justified by 6-8% higher real-world energy yield in hot markets.
