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 LR7-72HTDR-610M or Longi Solar LR7-72HTDR-605M?
According to our database: Longi Solar LR7-72HTDR-610M has higher module efficiency (22.60% vs 22.40%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Longi Solar LR7-72HTDR-610M and Longi Solar LR7-72HTDR-605M?
Longi Solar LR7-72HTDR-610M has a module efficiency of 22.60%, while Longi Solar LR7-72HTDR-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 LR7-72HTDR-610M use vs Longi Solar LR7-72HTDR-605M?
Longi Solar LR7-72HTDR-610M uses N-type cells; Longi Solar LR7-72HTDR-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 LR7-72HTDR-610M and Longi Solar LR7-72HTDR-605M?
Longi Solar LR7-72HTDR-610M has a 30 years power warranty; Longi Solar LR7-72HTDR-605M 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 LR7-72HTDR-610M and Longi Solar LR7-72HTDR-605M bifacial panels?
Both Longi Solar LR7-72HTDR-610M and Longi Solar LR7-72HTDR-605M are bifacial - they capture reflected light from the ground, which can add 5-15% more annual energy on ground-mount or elevated rooftop installations with a light surface beneath.
