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 (-0.290 %/°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: Sun Earth DXM8-72HBG 570W or Sun Earth DXM8-72HBG 580W?
According to our database: Sun Earth DXM8-72HBG 580 W has higher module efficiency (22.50% vs 22.10%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Sun Earth DXM8-72HBG 570W and Sun Earth DXM8-72HBG 580W?
Sun Earth DXM8-72HBG 570 W has a module efficiency of 22.10%, while Sun Earth DXM8-72HBG 580 W is 22.50%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Sun Earth DXM8-72HBG 570W use vs Sun Earth DXM8-72HBG 580W?
Sun Earth DXM8-72HBG 570 W uses TOPCon cells; Sun Earth DXM8-72HBG 580 W 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 Sun Earth DXM8-72HBG 570W and Sun Earth DXM8-72HBG 580W?
Sun Earth DXM8-72HBG 570 W has a 30 years power warranty; Sun Earth DXM8-72HBG 580 W 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 Sun Earth DXM8-72HBG 570W and Sun Earth DXM8-72HBG 580W bifacial panels?
Both Sun Earth DXM8-72HBG 570 W and Sun Earth DXM8-72HBG 580 W 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.
