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 (-0.340 %/°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: Sunplus SR5-60HBD-595M or Sunplus SR5-60HBD-590M?
According to our database: Sunplus SR5-60HBD-595M has higher module efficiency (21.00% vs 20.80%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Sunplus SR5-60HBD-595M and Sunplus SR5-60HBD-590M?
Sunplus SR5-60HBD-595M has a module efficiency of 21.00%, 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 SR5-60HBD-595M use vs Sunplus SR5-60HBD-590M?
Sunplus SR5-60HBD-595M uses PERC 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 SR5-60HBD-595M and Sunplus SR5-60HBD-590M?
Sunplus SR5-60HBD-595M 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 SR5-60HBD-595M and Sunplus SR5-60HBD-590M bifacial panels?
Both Sunplus SR5-60HBD-595M 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.
