HJT (Heterojunction Technology) combines crystalline silicon with thin-film layers, delivering very high efficiency and superior temperature performance.





Rayax 730 W HJT
The Rayax 730 W HJT Dual-Glass Solar Panel uses advanced Heterojunction Technology (HJT) to deliver high performance with a conversion efficiency of up to 23.5%. It provides an impressive peak power output of up to 795 Wp with combined front and rear-side efficiency. Designed with 132 high-efficiency cells, it enhances energy generation by up to 20%, and when installed at a height of 1.5 meters, output can increase by 7–20%. The panel features an IP68-rated junction box with three bypass diodes for superior protection and reliability, making it ideal for solar farms, ground-mounted, residential, commercial, and industrial applications .
