Questions about this pairing
Which panel is better: Sunplus 740 or Sunplus SR5-60HBD-590M?
According to our database: Sunplus 740 has higher module efficiency (23.80% vs 20.80%); Sunplus 740 tolerates heat better (temp coeff -0.300%/°C vs -0.340%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Sunplus 740 and Sunplus SR5-60HBD-590M?
Sunplus 740 has a module efficiency of 23.80%, while Sunplus SR5-60HBD-590M is 20.80%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Sunplus 740 use vs Sunplus SR5-60HBD-590M?
Sunplus 740 uses HJT cells; Sunplus SR5-60HBD-590M uses PERC. 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 Sunplus 740 and Sunplus SR5-60HBD-590M?
Sunplus 740 has a 30 years power warranty; Sunplus SR5-60HBD-590M 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 Sunplus 740 and Sunplus SR5-60HBD-590M bifacial panels?
Both Sunplus 740 and Sunplus SR5-60HBD-590M 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.
