Hyundai HIE-S410VG vs Hyundai HIE-S400VG

Q: Which panel is better: Hyundai HIE-S410VG or Hyundai HIE-S400VG?

According to our database: Hyundai HIE-S410VG has higher module efficiency (20.90% vs 20.40%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of Hyundai HIE-S410VG and Hyundai HIE-S400VG?

Hyundai HIE-S410VG has a module efficiency of 20.90%, while Hyundai HIE-S400VG is 20.40%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does Hyundai HIE-S410VG use vs Hyundai HIE-S400VG?

Hyundai HIE-S410VG uses PERC cells; Hyundai HIE-S400VG 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-S410VG and Hyundai HIE-S400VG?

Hyundai HIE-S410VG has a 25 years power warranty; Hyundai HIE-S400VG 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.

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.
