Which panel is better: Longi Solar LR7-72HGD-595M or Longi Solar LR7-72HVHF-670M?
According to our database: Longi Solar LR7-72HVHF-670M has higher module efficiency (24.80% vs 22.00%); Longi Solar LR7-72HVHF-670M tolerates heat better (temp coeff -0.260%/°C vs -0.280%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Longi Solar LR7-72HGD-595M and Longi Solar LR7-72HVHF-670M?
Longi Solar LR7-72HGD-595M has a module efficiency of 22.00%, while Longi Solar LR7-72HVHF-670M is 24.80%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Longi Solar LR7-72HGD-595M use vs Longi Solar LR7-72HVHF-670M?
Longi Solar LR7-72HGD-595M uses N-type cells; Longi Solar LR7-72HVHF-670M uses N-type. 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 LR7-72HGD-595M and Longi Solar LR7-72HVHF-670M?
Longi Solar LR7-72HGD-595M has a 30 years power warranty; Longi Solar LR7-72HVHF-670M 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 LR7-72HGD-595M and Longi Solar LR7-72HVHF-670M bifacial panels?
Longi Solar LR7-72HGD-595M is bifacial (captures light from both faces); Longi Solar LR7-72HVHF-670M is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
