Jinko Solar JKM615-635N-78HL4-(V)-F6-EN (635W variant) vs Jinko Solar JKM615-635N-78HL4-(V)-F6-EN (630W variant)
VS
The verdict
Identical on every published parameter
All 19 comparable parameters agree. Two records this alike are usually one panel sold under two names, or two bins of the same production line - decide on price and on who you would rather buy from.

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.
