Questions about this pairing

Which panel is better: Trina Solar TSM-NEG21C.20-730 or Runergy HY-DH132H10-735?
According to our database: Runergy HY-DH132H10-735 has higher module efficiency (23.70% vs 23.50%); Runergy HY-DH132H10-735 tolerates heat better (temp coeff -0.260%/°C vs -0.290%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Trina Solar TSM-NEG21C.20-730 and Runergy HY-DH132H10-735?
Trina Solar TSM-NEG21C.20-730 has a module efficiency of 23.50%, while Runergy HY-DH132H10-735 is 23.70%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Trina Solar TSM-NEG21C.20-730 use vs Runergy HY-DH132H10-735?
Trina Solar TSM-NEG21C.20-730 uses TOPCon cells; Runergy HY-DH132H10-735 uses HJT. 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 Trina Solar TSM-NEG21C.20-730 and Runergy HY-DH132H10-735?
Trina Solar TSM-NEG21C.20-730 has a 30 years power warranty; Runergy HY-DH132H10-735 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 Trina Solar TSM-NEG21C.20-730 and Runergy HY-DH132H10-735 bifacial panels?
Both Trina Solar TSM-NEG21C.20-730 and Runergy HY-DH132H10-735 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.
