What it means on a roof

Thirty years of production
Each panel's own declared degradation curve, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.280 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.

Questions about this pairing

Which panel is better: DAS Solar DAS-DH132NE-640W or DAS Solar DAS-DH132NC-715?
According to our database: DAS Solar DAS-DH132NE-640 W has higher module efficiency (23.70% vs 23.00%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of DAS Solar DAS-DH132NE-640W and DAS Solar DAS-DH132NC-715?
DAS Solar DAS-DH132NE-640 W has a module efficiency of 23.70%, while DAS Solar DAS-DH132NC-715 is 23.00%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does DAS Solar DAS-DH132NE-640W use vs DAS Solar DAS-DH132NC-715?
DAS Solar DAS-DH132NE-640 W uses TOPCon cells; DAS Solar DAS-DH132NC-715 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-DH132NE-640W and DAS Solar DAS-DH132NC-715?
DAS Solar DAS-DH132NE-640 W has a 30 years power warranty; DAS Solar DAS-DH132NC-715 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-DH132NE-640W and DAS Solar DAS-DH132NC-715 bifacial panels?
Both DAS Solar DAS-DH132NE-640 W and DAS Solar DAS-DH132NC-715 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.
