Questions about this pairing

Which panel is better: Q-Cells Q.TRON BLK M-G2+/AC (Power class 415W) or Q-Cells Q.PEAK DUO ML-G12S.3 / BFG 675?
According to our database: Q-Cells Q.PEAK DUO ML-G12S.3 / BFG 675 has higher module efficiency (21.70% vs 21.30%); Q-Cells Q.TRON BLK M-G2+/AC (Power class 415 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.TRON BLK M-G2+/AC (Power class 415W) and Q-Cells Q.PEAK DUO ML-G12S.3 / BFG 675?
Q-Cells Q.TRON BLK M-G2+/AC (Power class 415 W) has a module efficiency of 21.30%, while Q-Cells Q.PEAK DUO ML-G12S.3 / BFG 675 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 BLK M-G2+/AC (Power class 415W) use vs Q-Cells Q.PEAK DUO ML-G12S.3 / BFG 675?
Q-Cells Q.TRON BLK M-G2+/AC (Power class 415 W) uses N-type cells; Q-Cells Q.PEAK DUO ML-G12S.3 / BFG 675 uses Monocrystalline. 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+/AC (Power class 415W) and Q-Cells Q.PEAK DUO ML-G12S.3 / BFG 675?
Q-Cells Q.TRON BLK M-G2+/AC (Power class 415 W) has a 25 years power warranty; Q-Cells Q.PEAK DUO ML-G12S.3 / BFG 675 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+/AC (Power class 415W) and Q-Cells Q.PEAK DUO ML-G12S.3 / BFG 675 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+/AC (Power class 415 W) is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
