Questions about this pairing
Which panel is better: Longi Solar LR7-54HVB-480M or DMEGC DM465M10RT-B54HBW?
According to our database: Longi Solar LR7-54HVB-480M has higher module efficiency (23.50% vs 23.30%); Longi Solar LR7-54HVB-480M tolerates heat better (temp coeff -0.260%/°C vs -0.290%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Longi Solar LR7-54HVB-480M and DMEGC DM465M10RT-B54HBW?
Longi Solar LR7-54HVB-480M has a module efficiency of 23.50%, while DMEGC DM465M10RT-B54HBW is 23.30%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Longi Solar LR7-54HVB-480M use vs DMEGC DM465M10RT-B54HBW?
Longi Solar LR7-54HVB-480M uses N-type cells; DMEGC DM465M10RT-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 Longi Solar LR7-54HVB-480M and DMEGC DM465M10RT-B54HBW?
Longi Solar LR7-54HVB-480M has a 30 years power warranty; DMEGC DM465M10RT-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 Longi Solar LR7-54HVB-480M and DMEGC DM465M10RT-B54HBW bifacial panels?
DMEGC DM465M10RT-B54HBW is bifacial (captures light from both faces); Longi Solar LR7-54HVB-480M is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
