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 (-0.300 %/°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: ZNShine ZXM7-UHLD108-425/N or ZNShine ZXM7-UHLDD108-430?
According to our database: ZNShine ZXM7-UHLDD108-430 has higher module efficiency (22.02% vs 21.76%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of ZNShine ZXM7-UHLD108-425/N and ZNShine ZXM7-UHLDD108-430?
ZNShine ZXM7-UHLD108-425/N has a module efficiency of 21.76%, while ZNShine ZXM7-UHLDD108-430 is 22.02%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does ZNShine ZXM7-UHLD108-425/N use vs ZNShine ZXM7-UHLDD108-430?
ZNShine ZXM7-UHLD108-425/N uses TOPCon cells; ZNShine ZXM7-UHLDD108-430 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 ZNShine ZXM7-UHLD108-425/N and ZNShine ZXM7-UHLDD108-430?
ZNShine ZXM7-UHLD108-425/N has a 30 years power warranty; ZNShine ZXM7-UHLDD108-430 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 ZNShine ZXM7-UHLD108-425/N and ZNShine ZXM7-UHLDD108-430 bifacial panels?
Both ZNShine ZXM7-UHLD108-425/N and ZNShine ZXM7-UHLDD108-430 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.
