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 (-0.290 %/°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: Renesola RS7-620N-E2 or Renesola RS7-630N-E2?
According to our database: Renesola RS7-630N-E2 has higher module efficiency (22.54% vs 22.18%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Renesola RS7-620N-E2 and Renesola RS7-630N-E2?
Renesola RS7-620N-E2 has a module efficiency of 22.18%, while Renesola RS7-630N-E2 is 22.54%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Renesola RS7-620N-E2 use vs Renesola RS7-630N-E2?
Renesola RS7-620N-E2 uses N-type cells; Renesola RS7-630N-E2 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 Renesola RS7-620N-E2 and Renesola RS7-630N-E2?
Renesola RS7-620N-E2 has a 30 years power warranty; Renesola RS7-630N-E2 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.
