What it means on a roof

Thirty years of production
Each panel's own declared degradation curve, at 1,200 kWh/kWp a year
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.

Questions about this pairing

Which panel is better: Q-Cells Q.TRON BLK M-G2+ 430 or GCL NT12R/48GDF-455W?
According to our database: GCL NT12R/48GDF-455 W has higher module efficiency (22.77% vs 22.00%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Q-Cells Q.TRON BLK M-G2+ 430 and GCL NT12R/48GDF-455W?
Q-Cells Q.TRON BLK M-G2+ 430 has a module efficiency of 22.00%, while GCL NT12R/48GDF-455 W is 22.77%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Q-Cells Q.TRON BLK M-G2+ 430 use vs GCL NT12R/48GDF-455W?
Q-Cells Q.TRON BLK M-G2+ 430 uses N-type cells; GCL NT12R/48GDF-455 W uses TOPCon. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.
What is the warranty on Q-Cells Q.TRON BLK M-G2+ 430 and GCL NT12R/48GDF-455W?
Q-Cells Q.TRON BLK M-G2+ 430 has a 25 years power warranty; GCL NT12R/48GDF-455 W 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.
Are Q-Cells Q.TRON BLK M-G2+ 430 and GCL NT12R/48GDF-455W bifacial panels?
GCL NT12R/48GDF-455 W is bifacial (captures light from both faces); Q-Cells Q.TRON BLK M-G2+ 430 is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
