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 (-0.340 %/°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: Longi Solar LR5-66HPH-510M or Longi Solar LR5-72HPH-560M?
According to our database: Longi Solar LR5-72HPH-560M has higher module efficiency (21.70% vs 21.50%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Longi Solar LR5-66HPH-510M and Longi Solar LR5-72HPH-560M?
Longi Solar LR5-66HPH-510M has a module efficiency of 21.50%, while Longi Solar LR5-72HPH-560M is 21.70%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Longi Solar LR5-66HPH-510M use vs Longi Solar LR5-72HPH-560M?
Longi Solar LR5-66HPH-510M uses Monocrystalline cells; Longi Solar LR5-72HPH-560M uses PERC. 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 LR5-66HPH-510M and Longi Solar LR5-72HPH-560M?
Longi Solar LR5-66HPH-510M has a 25 years power warranty; Longi Solar LR5-72HPH-560M has a 25 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.
