Jinko Solar JKM450-475N-48HL4M-DV (470W class) vs GCL NT12R/48GDF-455W

Q: Which panel is better: Jinko Solar JKM450-475N-48HL4M-DV (470W class) or GCL NT12R/48GDF-455W?

According to our database: Jinko Solar JKM450-475N-48HL4M-DV (470W class) has higher module efficiency (23.52% vs 22.77%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of Jinko Solar JKM450-475N-48HL4M-DV (470W class) and GCL NT12R/48GDF-455W?

Jinko Solar JKM450-475N-48HL4M-DV (470W class) has a module efficiency of 23.52%, while GCL NT12R/48GDF-455W is 22.77%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does Jinko Solar JKM450-475N-48HL4M-DV (470W class) use vs GCL NT12R/48GDF-455W?

Jinko Solar JKM450-475N-48HL4M-DV (470W class) uses TOPCon cells; GCL NT12R/48GDF-455W uses TOPCon. 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 Jinko Solar JKM450-475N-48HL4M-DV (470W class) and GCL NT12R/48GDF-455W?

Jinko Solar JKM450-475N-48HL4M-DV (470W class) has a 30 years power warranty; GCL NT12R/48GDF-455W 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.

Q: Are Jinko Solar JKM450-475N-48HL4M-DV (470W class) and GCL NT12R/48GDF-455W bifacial panels?

GCL NT12R/48GDF-455W is bifacial (captures light from both faces); Jinko Solar JKM450-475N-48HL4M-DV (470W class) is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.

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 (-0.290 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.
