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 (-0.270 %/°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: Maxeon SPR-MAX3-380-COM or Maxeon SPR-MAX3-430-R?
According to our database: Maxeon SPR-MAX3-430-R has higher module efficiency (22.70% vs 21.50%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Maxeon SPR-MAX3-380-COM and Maxeon SPR-MAX3-430-R?
Maxeon SPR-MAX3-380-COM has a module efficiency of 21.50%, while Maxeon SPR-MAX3-430-R is 22.70%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Maxeon SPR-MAX3-380-COM use vs Maxeon SPR-MAX3-430-R?
Maxeon SPR-MAX3-380-COM uses Back Contact cells; Maxeon SPR-MAX3-430-R uses Back Contact. 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 Maxeon SPR-MAX3-380-COM and Maxeon SPR-MAX3-430-R?
Maxeon SPR-MAX3-380-COM has a 40 years power warranty; Maxeon SPR-MAX3-430-R has a 40 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.
