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 (-0.240 %/°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: Reliance New Energy RNE710AA-66-BGG or Reliance New Energy RNE720AA-66-BGG?
According to our database: Reliance New Energy RNE720AA-66-BGG has higher module efficiency (23.10% vs 22.80%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Reliance New Energy RNE710AA-66-BGG and Reliance New Energy RNE720AA-66-BGG?
Reliance New Energy RNE710AA-66-BGG has a module efficiency of 22.80%, while Reliance New Energy RNE720AA-66-BGG is 23.10%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Reliance New Energy RNE710AA-66-BGG use vs Reliance New Energy RNE720AA-66-BGG?
Reliance New Energy RNE710AA-66-BGG uses HJT cells; Reliance New Energy RNE720AA-66-BGG uses HJT. 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 Reliance New Energy RNE710AA-66-BGG and Reliance New Energy RNE720AA-66-BGG?
Reliance New Energy RNE710AA-66-BGG has a 30 years power warranty; Reliance New Energy RNE720AA-66-BGG 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 Reliance New Energy RNE710AA-66-BGG and Reliance New Energy RNE720AA-66-BGG bifacial panels?
Both Reliance New Energy RNE710AA-66-BGG and Reliance New Energy RNE720AA-66-BGG 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.
