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 (-0.300 %/°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 XL-G2.3 / BFG 610 or Q-Cells Q.TRON XL-G2.3 / BFG 630?
According to our database: Q-Cells Q.TRON XL-G2.3 / BFG 630 has higher module efficiency (22.60% vs 21.80%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Q-Cells Q.TRON XL-G2.3 / BFG 610 and Q-Cells Q.TRON XL-G2.3 / BFG 630?
Q-Cells Q.TRON XL-G2.3 / BFG 610 has a module efficiency of 21.80%, while Q-Cells Q.TRON XL-G2.3 / BFG 630 is 22.60%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Q-Cells Q.TRON XL-G2.3 / BFG 610 use vs Q-Cells Q.TRON XL-G2.3 / BFG 630?
Q-Cells Q.TRON XL-G2.3 / BFG 610 uses N-type cells; Q-Cells Q.TRON XL-G2.3 / BFG 630 uses N-type. 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 XL-G2.3 / BFG 610 and Q-Cells Q.TRON XL-G2.3 / BFG 630?
Q-Cells Q.TRON XL-G2.3 / BFG 610 has a 30 years power warranty; Q-Cells Q.TRON XL-G2.3 / BFG 630 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 XL-G2.3 / BFG 610 and Q-Cells Q.TRON XL-G2.3 / BFG 630 bifacial panels?
Both Q-Cells Q.TRON XL-G2.3 / BFG 610 and Q-Cells Q.TRON XL-G2.3 / BFG 630 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.
