Questions about this pairing
Which panel is better: Renesola RS5J-615NBG-E1 or Renesola RS9-720NBG-E1?
According to our database: Renesola RS9-720NBG-E1 has higher module efficiency (23.18% vs 22.77%); Renesola RS9-720NBG-E1 tolerates heat better (temp coeff -0.290%/°C vs -0.300%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Renesola RS5J-615NBG-E1 and Renesola RS9-720NBG-E1?
Renesola RS5J-615NBG-E1 has a module efficiency of 22.77%, while Renesola RS9-720NBG-E1 is 23.18%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Renesola RS5J-615NBG-E1 use vs Renesola RS9-720NBG-E1?
Renesola RS5J-615NBG-E1 uses N-type cells; Renesola RS9-720NBG-E1 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 RS5J-615NBG-E1 and Renesola RS9-720NBG-E1?
Renesola RS5J-615NBG-E1 has a 30 years power warranty; Renesola RS9-720NBG-E1 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 Renesola RS5J-615NBG-E1 and Renesola RS9-720NBG-E1 bifacial panels?
Both Renesola RS5J-615NBG-E1 and Renesola RS9-720NBG-E1 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.
