DAS Solar DAS-DH120NA-485 vs DAS Solar DAS-DH120ND-500W

Q: Which panel is better: DAS Solar DAS-DH120NA-485 or DAS Solar DAS-DH120ND-500W?

According to our database: DAS Solar DAS-DH120NA-485 has higher module efficiency (22.50% vs 22.10%); DAS Solar DAS-DH120ND-500W 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.

Q: What is the efficiency of DAS Solar DAS-DH120NA-485 and DAS Solar DAS-DH120ND-500W?

DAS Solar DAS-DH120NA-485 has a module efficiency of 22.50%, while DAS Solar DAS-DH120ND-500W is 22.10%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does DAS Solar DAS-DH120NA-485 use vs DAS Solar DAS-DH120ND-500W?

DAS Solar DAS-DH120NA-485 uses TOPCon cells; DAS Solar DAS-DH120ND-500W uses TOPCon. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.

Q: What is the warranty on DAS Solar DAS-DH120NA-485 and DAS Solar DAS-DH120ND-500W?

DAS Solar DAS-DH120NA-485 has a 30 years power warranty; DAS Solar DAS-DH120ND-500W 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.

Q: Are DAS Solar DAS-DH120NA-485 and DAS Solar DAS-DH120ND-500W bifacial panels?

Both DAS Solar DAS-DH120NA-485 and DAS Solar DAS-DH120ND-500W 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.
