Hyundai HIE-S390VG vs Hyundai HIE-S410VG

Q: Which panel is better: Hyundai HIE-S390VG or Hyundai HIE-S410VG?

According to our database: Hyundai HIE-S410VG has higher module efficiency (20.90% vs 19.90%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of Hyundai HIE-S390VG and Hyundai HIE-S410VG?

Hyundai HIE-S390VG has a module efficiency of 19.90%, while Hyundai HIE-S410VG is 20.90%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does Hyundai HIE-S390VG use vs Hyundai HIE-S410VG?

Hyundai HIE-S390VG uses PERC cells; Hyundai HIE-S410VG 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-S390VG and Hyundai HIE-S410VG?

Hyundai HIE-S390VG has a 25 years power warranty; Hyundai HIE-S410VG 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.
