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 (-0.290 %/°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: Silfab SIL-430-QD or Silfab SIL-430 QD?
According to our database: both panels are closely matched on key specs - the decision often comes down to price and local availability. See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Silfab SIL-430-QD and Silfab SIL-430 QD?
Silfab SIL-430-QD has a module efficiency of 22.10%, while Silfab SIL-430 QD is 22.10%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Silfab SIL-430-QD use vs Silfab SIL-430 QD?
Silfab SIL-430-QD uses N-type cells; Silfab SIL-430 QD uses N-type. 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 Silfab SIL-430-QD and Silfab SIL-430 QD?
Silfab SIL-430-QD has a 30 years power warranty; Silfab SIL-430 QD 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.
