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 DM450M10RT-B54HBW or DMEGC DM465M10RT-B54HSW?
According to our database: DMEGC DM465M10RT-B54HSW has higher module efficiency (23.30% vs 22.50%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of DMEGC DM450M10RT-B54HBW and DMEGC DM465M10RT-B54HSW?
DMEGC DM450M10RT-B54HBW has a module efficiency of 22.50%, while DMEGC DM465M10RT-B54HSW is 23.30%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does DMEGC DM450M10RT-B54HBW use vs DMEGC DM465M10RT-B54HSW?
DMEGC DM450M10RT-B54HBW uses TOPCon cells; DMEGC DM465M10RT-B54HSW 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 DM450M10RT-B54HBW and DMEGC DM465M10RT-B54HSW?
DMEGC DM450M10RT-B54HBW has a 30 years power warranty; DMEGC DM465M10RT-B54HSW 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 DM450M10RT-B54HBW and DMEGC DM465M10RT-B54HSW bifacial panels?
Both DMEGC DM450M10RT-B54HBW and DMEGC DM465M10RT-B54HSW 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.
