Questions about this pairing
Which panel is better: Longi Solar LR5-54HPB-410M or Longi Solar LR7-54HVH-490M?
According to our database: Longi Solar LR7-54HVH-490M has higher module efficiency (24.00% vs 21.00%); Longi Solar LR7-54HVH-490M tolerates heat better (temp coeff -0.260%/°C vs -0.340%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Longi Solar LR5-54HPB-410M and Longi Solar LR7-54HVH-490M?
Longi Solar LR5-54HPB-410M has a module efficiency of 21.00%, while Longi Solar LR7-54HVH-490M is 24.00%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Longi Solar LR5-54HPB-410M use vs Longi Solar LR7-54HVH-490M?
Longi Solar LR5-54HPB-410M uses PERC cells; Longi Solar LR7-54HVH-490M 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 LR5-54HPB-410M and Longi Solar LR7-54HVH-490M?
Longi Solar LR5-54HPB-410M has a 25 years power warranty; Longi Solar LR7-54HVH-490M 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.
