Questions about this pairing

Which panel is better: Q-Cells Q.TRON BLK M-G2+ 430 or Q-Cells Q.TRON BLK M-G2.D1+/AC (Power class 435W)?
According to our database: Q-Cells Q.TRON BLK M-G2.D1+/AC (Power class 435 W) has higher module efficiency (22.30% vs 22.00%); Q-Cells Q.TRON BLK M-G2+ 430 tolerates heat better (temp coeff -0.290%/°C vs -0.300%/°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+ 430 and Q-Cells Q.TRON BLK M-G2.D1+/AC (Power class 435W)?
Q-Cells Q.TRON BLK M-G2+ 430 has a module efficiency of 22.00%, while Q-Cells Q.TRON BLK M-G2.D1+/AC (Power class 435 W) is 22.30%. 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+ 430 use vs Q-Cells Q.TRON BLK M-G2.D1+/AC (Power class 435W)?
Q-Cells Q.TRON BLK M-G2+ 430 uses N-type cells; Q-Cells Q.TRON BLK M-G2.D1+/AC (Power class 435 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.TRON BLK M-G2+ 430 and Q-Cells Q.TRON BLK M-G2.D1+/AC (Power class 435W)?
Q-Cells Q.TRON BLK M-G2+ 430 has a 25 years power warranty; Q-Cells Q.TRON BLK M-G2.D1+/AC (Power class 435 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.
