GCL NT12R/48GDF-455W vs GCL NT12R/48GDF-465W

Q: Which panel is better: GCL NT12R/48GDF-455W or GCL NT12R/48GDF-465W?

According to our database: GCL NT12R/48GDF-465W has higher module efficiency (23.27% vs 22.77%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of GCL NT12R/48GDF-455W and GCL NT12R/48GDF-465W?

GCL NT12R/48GDF-455W has a module efficiency of 22.77%, while GCL NT12R/48GDF-465W is 23.27%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does GCL NT12R/48GDF-455W use vs GCL NT12R/48GDF-465W?

GCL NT12R/48GDF-455W uses TOPCon cells; GCL NT12R/48GDF-465W 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 GCL NT12R/48GDF-455W and GCL NT12R/48GDF-465W?

GCL NT12R/48GDF-455W has a 30 years power warranty; GCL NT12R/48GDF-465W 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 GCL NT12R/48GDF-455W and GCL NT12R/48GDF-465W bifacial panels?

Both GCL NT12R/48GDF-455W and GCL NT12R/48GDF-465W 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.

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.
