Ultra-low annual degradation of 0.35%/year. Best long-term energy yield guarantee in the market.
Symmetrical HJT cell structure performs better in overcast, early morning, and late afternoon conditions.
25-year product warranty + 30-year linear performance warranty backed by manufacturer guarantee.
The JUSTSOLAR HJT 730W represents our premium technology offering, using Heterojunction (HJT) cell architecture that delivers the best temperature coefficient in the industry at -0.24%/C. This means 6-8% more real-world energy yield compared to PERC modules in hot climates like the Middle East, Africa, and Southeast Asia. With 85% bifaciality (vs. 80% for TOPCon), it captures more rear-side irradiance, further boosting total generation. HJT cells feature virtually zero LID (Light Induced Degradation) and extremely low first-year degradation of just 1%, maintaining 88.8% rated power after 25 years. The symmetrical cell structure performs equally well in low-light conditions (overcast, early morning, late afternoon), maximizing daily energy yield. For projects where lifetime energy yield justifies a premium module cost, the HJT 730W delivers the best return on investment.
