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: DMEGC DM720G12T-B66HSW or DMEGC DM710G12T-B66HSW?
According to our database: DMEGC DM720G12T-B66HSW has higher module efficiency (23.20% vs 22.90%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of DMEGC DM720G12T-B66HSW and DMEGC DM710G12T-B66HSW?
DMEGC DM720G12T-B66HSW has a module efficiency of 23.20%, while DMEGC DM710G12T-B66HSW is 22.90%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does DMEGC DM720G12T-B66HSW use vs DMEGC DM710G12T-B66HSW?
DMEGC DM720G12T-B66HSW uses TOPCon cells; DMEGC DM710G12T-B66HSW 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 DMEGC DM720G12T-B66HSW and DMEGC DM710G12T-B66HSW?
DMEGC DM720G12T-B66HSW has a 30 years power warranty; DMEGC DM710G12T-B66HSW 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 DMEGC DM720G12T-B66HSW and DMEGC DM710G12T-B66HSW bifacial panels?
Both DMEGC DM720G12T-B66HSW and DMEGC DM710G12T-B66HSW 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.
