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-570 XM+ or Silfab SIL-530 XM?
According to our database: Silfab SIL-530 XM has higher module efficiency (22.30% vs 22.10%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Silfab SIL-570 XM+ and Silfab SIL-530 XM?
Silfab SIL-570 XM+ has a module efficiency of 22.10%, while Silfab SIL-530 XM is 22.30%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Silfab SIL-570 XM+ use vs Silfab SIL-530 XM?
Silfab SIL-570 XM+ uses N-type cells; Silfab SIL-530 XM 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-570 XM+ and Silfab SIL-530 XM?
Silfab SIL-570 XM+ has a 30 years power warranty; Silfab SIL-530 XM 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 Silfab SIL-570 XM+ and Silfab SIL-530 XM bifacial panels?
Both Silfab SIL-570 XM+ and Silfab SIL-530 XM 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.
