Questions about this pairing

Which panel is better: DAS Solar DAS-DH108NA-435 or DAS Solar DAS-DH108ND-440?
According to our database: DAS Solar DAS-DH108NA-435 has higher module efficiency (22.30% vs 21.60%); DAS Solar DAS-DH108ND-440 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-435 and DAS Solar DAS-DH108ND-440?
DAS Solar DAS-DH108NA-435 has a module efficiency of 22.30%, while DAS Solar DAS-DH108ND-440 is 21.60%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does DAS Solar DAS-DH108NA-435 use vs DAS Solar DAS-DH108ND-440?
DAS Solar DAS-DH108NA-435 uses TOPCon cells; DAS Solar DAS-DH108ND-440 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-435 and DAS Solar DAS-DH108ND-440?
DAS Solar DAS-DH108NA-435 has a 30 years power warranty; DAS Solar DAS-DH108ND-440 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-435 and DAS Solar DAS-DH108ND-440 bifacial panels?
Both DAS Solar DAS-DH108NA-435 and DAS Solar DAS-DH108ND-440 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.
