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 (-0.240 %/°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: Sunpro Power SP620W-210R-132DS or Sunpro Power SP610W-210R-132DS?
According to our database: Sunpro Power SP620 W-210R-132DS has higher module efficiency (22.95% vs 22.58%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Sunpro Power SP620W-210R-132DS and Sunpro Power SP610W-210R-132DS?
Sunpro Power SP620 W-210R-132DS has a module efficiency of 22.95%, while Sunpro Power SP610 W-210R-132DS is 22.58%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Sunpro Power SP620W-210R-132DS use vs Sunpro Power SP610W-210R-132DS?
Sunpro Power SP620 W-210R-132DS uses HJT cells; Sunpro Power SP610 W-210R-132DS 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 Sunpro Power SP620W-210R-132DS and Sunpro Power SP610W-210R-132DS?
Sunpro Power SP620 W-210R-132DS has a 30 years power warranty; Sunpro Power SP610 W-210R-132DS 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 Sunpro Power SP620W-210R-132DS and Sunpro Power SP610W-210R-132DS bifacial panels?
Both Sunpro Power SP620 W-210R-132DS and Sunpro Power SP610 W-210R-132DS 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.
