Questions about this pairing
Which panel is better: Sunplus SR5-60HBD-580M or Sunplus 745?
According to our database: Sunplus 745 has higher module efficiency (24.00% vs 20.50%); Sunplus 745 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 SR5-60HBD-580M and Sunplus 745?
Sunplus SR5-60HBD-580M has a module efficiency of 20.50%, while Sunplus 745 is 24.00%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Sunplus SR5-60HBD-580M use vs Sunplus 745?
Sunplus SR5-60HBD-580M uses PERC cells; Sunplus 745 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 Sunplus SR5-60HBD-580M and Sunplus 745?
Sunplus SR5-60HBD-580M has a 30 years power warranty; Sunplus 745 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 SR5-60HBD-580M and Sunplus 745 bifacial panels?
Both Sunplus SR5-60HBD-580M and Sunplus 745 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.
