Questions about this pairing

Which panel is better: Q-Cells Q.TRON XL-G2.3 / BFG 630 or Q-Cells Q.PEAK DUO XL-G11S.3 / BFG 605?
According to our database: Q-Cells Q.TRON XL-G2.3 / BFG 630 has higher module efficiency (22.60% vs 21.70%); Q-Cells Q.TRON XL-G2.3 / BFG 630 tolerates heat better (temp coeff -0.300%/°C vs -0.340%/°C). 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 630 and Q-Cells Q.PEAK DUO XL-G11S.3 / BFG 605?
Q-Cells Q.TRON XL-G2.3 / BFG 630 has a module efficiency of 22.60%, while Q-Cells Q.PEAK DUO XL-G11S.3 / BFG 605 is 21.70%. 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 630 use vs Q-Cells Q.PEAK DUO XL-G11S.3 / BFG 605?
Q-Cells Q.TRON XL-G2.3 / BFG 630 uses N-type cells; Q-Cells Q.PEAK DUO XL-G11S.3 / BFG 605 uses PERC. 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 630 and Q-Cells Q.PEAK DUO XL-G11S.3 / BFG 605?
Q-Cells Q.TRON XL-G2.3 / BFG 630 has a 30 years power warranty; Q-Cells Q.PEAK DUO XL-G11S.3 / BFG 605 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 630 and Q-Cells Q.PEAK DUO XL-G11S.3 / BFG 605 bifacial panels?
Both Q-Cells Q.TRON XL-G2.3 / BFG 630 and Q-Cells Q.PEAK DUO XL-G11S.3 / BFG 605 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.
