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 (-0.280 %/°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 LR5-72HTD-575M or Longi Solar LR7-72HTH-605M?
According to our database: Longi Solar LR7-72HTH-605M has higher module efficiency (22.40% vs 22.30%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Longi Solar LR5-72HTD-575M and Longi Solar LR7-72HTH-605M?
Longi Solar LR5-72HTD-575M has a module efficiency of 22.30%, while Longi Solar LR7-72HTH-605M is 22.40%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Longi Solar LR5-72HTD-575M use vs Longi Solar LR7-72HTH-605M?
Longi Solar LR5-72HTD-575M uses Monocrystalline cells; Longi Solar LR7-72HTH-605M 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 LR5-72HTD-575M and Longi Solar LR7-72HTH-605M?
Longi Solar LR5-72HTD-575M has a 30 years power warranty; Longi Solar LR7-72HTH-605M 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.
Are Longi Solar LR5-72HTD-575M and Longi Solar LR7-72HTH-605M bifacial panels?
Longi Solar LR5-72HTD-575M is bifacial (captures light from both faces); Longi Solar LR7-72HTH-605M is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
