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 (-0.300 %/°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: IBC Solar IBC Module White 455 MS-TA1 or IBC Solar White 455 MS-TA1?
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 IBC Solar IBC Module White 455 MS-TA1 and IBC Solar White 455 MS-TA1?
IBC Solar IBC Module White 455 MS-TA1 has a module efficiency of 22.77%, while IBC Solar White 455 MS-TA1 is 22.77%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does IBC Solar IBC Module White 455 MS-TA1 use vs IBC Solar White 455 MS-TA1?
IBC Solar IBC Module White 455 MS-TA1 uses TOPCon cells; IBC Solar White 455 MS-TA1 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 IBC Solar IBC Module White 455 MS-TA1 and IBC Solar White 455 MS-TA1?
IBC Solar IBC Module White 455 MS-TA1 has a 30 years power warranty; IBC Solar White 455 MS-TA1 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.
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.
