Questions about this pairing
Which panel is better: Longi Solar LR5-72HTH-565M or Longi Solar LR7-72HVHF-670M?
According to our database: Longi Solar LR7-72HVHF-670M has higher module efficiency (24.80% vs 21.90%); Longi Solar LR7-72HVHF-670M 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 LR5-72HTH-565M and Longi Solar LR7-72HVHF-670M?
Longi Solar LR5-72HTH-565M has a module efficiency of 21.90%, 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 LR5-72HTH-565M use vs Longi Solar LR7-72HVHF-670M?
Longi Solar LR5-72HTH-565M uses Monocrystalline 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 LR5-72HTH-565M and Longi Solar LR7-72HVHF-670M?
Longi Solar LR5-72HTH-565M has a 25 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.
