Hyundai HiE-S430HG(FB) vs Hyundai HiE-S445HG

Q: Which panel is better: Hyundai HiE-S430HG(FB) or Hyundai HiE-S445HG?

According to our database: Hyundai HiE-S445HG has higher module efficiency (21.40% vs 20.70%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of Hyundai HiE-S430HG(FB) and Hyundai HiE-S445HG?

Hyundai HiE-S430HG(FB) has a module efficiency of 20.70%, while Hyundai HiE-S445HG is 21.40%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does Hyundai HiE-S430HG(FB) use vs Hyundai HiE-S445HG?

Hyundai HiE-S430HG(FB) uses PERC cells; Hyundai HiE-S445HG uses PERC. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.

Q: What is the warranty on Hyundai HiE-S430HG(FB) and Hyundai HiE-S445HG?

Hyundai HiE-S430HG(FB) has a 25 years power warranty; Hyundai HiE-S445HG has a 25 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.

What it means on a roof

Thirty years of production

Each panel's own declared degradation curve, at 1,200 kWh/kWp a year

Cell temperature

Same temp coeff. for both panels (-0.340 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.
