Questions about this pairing

Which panel is better: DAS Solar DAS-DH108NA-440W or DAS Solar DAS-DH108ND-460?
According to our database: DAS Solar DAS-DH108ND-460 tolerates heat better (temp coeff -0.280%/°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 DAS Solar DAS-DH108NA-440W and DAS Solar DAS-DH108ND-460?
DAS Solar DAS-DH108NA-440 W has a module efficiency of 22.50%, while DAS Solar DAS-DH108ND-460 is 22.50%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does DAS Solar DAS-DH108NA-440W use vs DAS Solar DAS-DH108ND-460?
DAS Solar DAS-DH108NA-440 W uses TOPCon cells; DAS Solar DAS-DH108ND-460 uses TOPCon. 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 DAS Solar DAS-DH108NA-440W and DAS Solar DAS-DH108ND-460?
DAS Solar DAS-DH108NA-440 W has a 30 years power warranty; DAS Solar DAS-DH108ND-460 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 DAS Solar DAS-DH108NA-440W and DAS Solar DAS-DH108ND-460 bifacial panels?
Both DAS Solar DAS-DH108NA-440 W and DAS Solar DAS-DH108ND-460 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.
