Questions about this pairing

Which panel is better: Q-Cells Q.TRON BLK M-G2.D1+/AC (Power class 435W) or Q-Cells Q.PEAK DUO ML-G12S.3 / BFG 670?
According to our database: Q-Cells Q.TRON BLK M-G2.D1+/AC (Power class 435 W) has higher module efficiency (22.30% vs 21.60%); Q-Cells Q.TRON BLK M-G2.D1+/AC (Power class 435 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.D1+/AC (Power class 435W) and Q-Cells Q.PEAK DUO ML-G12S.3 / BFG 670?
Q-Cells Q.TRON BLK M-G2.D1+/AC (Power class 435 W) has a module efficiency of 22.30%, while Q-Cells Q.PEAK DUO ML-G12S.3 / BFG 670 is 21.60%. 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.D1+/AC (Power class 435W) use vs Q-Cells Q.PEAK DUO ML-G12S.3 / BFG 670?
Q-Cells Q.TRON BLK M-G2.D1+/AC (Power class 435 W) uses N-type cells; Q-Cells Q.PEAK DUO ML-G12S.3 / BFG 670 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.D1+/AC (Power class 435W) and Q-Cells Q.PEAK DUO ML-G12S.3 / BFG 670?
Q-Cells Q.TRON BLK M-G2.D1+/AC (Power class 435 W) has a 25 years power warranty; Q-Cells Q.PEAK DUO ML-G12S.3 / BFG 670 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.D1+/AC (Power class 435W) and Q-Cells Q.PEAK DUO ML-G12S.3 / BFG 670 bifacial panels?
Q-Cells Q.PEAK DUO ML-G12S.3 / BFG 670 is bifacial (captures light from both faces); Q-Cells Q.TRON BLK M-G2.D1+/AC (Power class 435 W) is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
