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: Goldi Solar GS10-M156-WF-600 or Goldi Solar GS10-M156-WF-580?
According to our database: Goldi Solar GS10-M156-WF-600 has higher module efficiency (21.50% vs 20.70%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Goldi Solar GS10-M156-WF-600 and Goldi Solar GS10-M156-WF-580?
Goldi Solar GS10-M156-WF-600 has a module efficiency of 21.50%, while Goldi Solar GS10-M156-WF-580 is 20.70%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Goldi Solar GS10-M156-WF-600 use vs Goldi Solar GS10-M156-WF-580?
Goldi Solar GS10-M156-WF-600 uses PERC cells; Goldi Solar GS10-M156-WF-580 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 Goldi Solar GS10-M156-WF-600 and Goldi Solar GS10-M156-WF-580?
Goldi Solar GS10-M156-WF-600 has a 25 years power warranty; Goldi Solar GS10-M156-WF-580 has a 25 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.

Every figure here is from the manufacturers' own datasheets - a dash means the value is not published, never an estimate. The thirty-year projection and the temperature scenarios are calculations from those figures, and each states its assumption above.
