Questions about this pairing

Which panel is better: Q-Cells Q.PEAK DUO ML-G12S.3 / BFG 675 or Q-Cells Q.TRON BLK M-G2.H1+/AC (Power class 440W)?
According to our database: Q-Cells Q.TRON BLK M-G2.H1+/AC (Power class 440 W) has higher module efficiency (22.50% vs 21.70%); Q-Cells Q.TRON BLK M-G2.H1+/AC (Power class 440 W) 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.PEAK DUO ML-G12S.3 / BFG 675 and Q-Cells Q.TRON BLK M-G2.H1+/AC (Power class 440W)?
Q-Cells Q.PEAK DUO ML-G12S.3 / BFG 675 has a module efficiency of 21.70%, while Q-Cells Q.TRON BLK M-G2.H1+/AC (Power class 440 W) is 22.50%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Q-Cells Q.PEAK DUO ML-G12S.3 / BFG 675 use vs Q-Cells Q.TRON BLK M-G2.H1+/AC (Power class 440W)?
Q-Cells Q.PEAK DUO ML-G12S.3 / BFG 675 uses Monocrystalline cells; Q-Cells Q.TRON BLK M-G2.H1+/AC (Power class 440 W) 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.PEAK DUO ML-G12S.3 / BFG 675 and Q-Cells Q.TRON BLK M-G2.H1+/AC (Power class 440W)?
Q-Cells Q.PEAK DUO ML-G12S.3 / BFG 675 has a 30 years power warranty; Q-Cells Q.TRON BLK M-G2.H1+/AC (Power class 440 W) has a 25 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.PEAK DUO ML-G12S.3 / BFG 675 and Q-Cells Q.TRON BLK M-G2.H1+/AC (Power class 440W) bifacial panels?
Q-Cells Q.PEAK DUO ML-G12S.3 / BFG 675 is bifacial (captures light from both faces); Q-Cells Q.TRON BLK M-G2.H1+/AC (Power class 440 W) is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
