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 DM460M10RT-B54HBB or DMEGC DM460M10RT-B54HBW?
According to our database: both panels are closely matched on key specs - the decision often comes down to price and local availability. See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of DMEGC DM460M10RT-B54HBB and DMEGC DM460M10RT-B54HBW?
DMEGC DM460M10RT-B54HBB has a module efficiency of 23.00%, while DMEGC DM460M10RT-B54HBW is 23.00%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does DMEGC DM460M10RT-B54HBB use vs DMEGC DM460M10RT-B54HBW?
DMEGC DM460M10RT-B54HBB uses TOPCon cells; DMEGC DM460M10RT-B54HBW 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 DM460M10RT-B54HBB and DMEGC DM460M10RT-B54HBW?
DMEGC DM460M10RT-B54HBB has a 30 years power warranty; DMEGC DM460M10RT-B54HBW 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 DM460M10RT-B54HBB and DMEGC DM460M10RT-B54HBW bifacial panels?
Both DMEGC DM460M10RT-B54HBB and DMEGC DM460M10RT-B54HBW 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.
