Questions about this pairing

Which panel is better: Hyundai HiS-T630NJ or Hyundai HiT-H505LF-FB(ZB)?
According to our database: Hyundai HiT-H505LF-FB(ZB) has higher module efficiency (22.70% vs 22.54%); Hyundai HiT-H505LF-FB(ZB) tolerates heat better (temp coeff -0.240%/°C vs -0.290%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Hyundai HiS-T630NJ and Hyundai HiT-H505LF-FB(ZB)?
Hyundai HiS-T630NJ has a module efficiency of 22.54%, while Hyundai HiT-H505LF-FB(ZB) is 22.70%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Hyundai HiS-T630NJ use vs Hyundai HiT-H505LF-FB(ZB)?
Hyundai HiS-T630NJ uses TOPCon cells; Hyundai HiT-H505LF-FB(ZB) uses HJT. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.
What is the warranty on Hyundai HiS-T630NJ and Hyundai HiT-H505LF-FB(ZB)?
Hyundai HiS-T630NJ has a 30 years power warranty; Hyundai HiT-H505LF-FB(ZB) has a 30 years power warranty. The power warranty guarantees a minimum percentage of rated output at the end of the warranty period (typically 80-87%). Product (materials) warranties are usually shorter.
Are Hyundai HiS-T630NJ and Hyundai HiT-H505LF-FB(ZB) bifacial panels?
Both Hyundai HiS-T630NJ and Hyundai HiT-H505LF-FB(ZB) are bifacial - they capture reflected light from the ground, which can add 5-15% more annual energy on ground-mount or elevated rooftop installations with a light surface beneath.
