The verdict

Identical on every published parameter

All 18 comparable parameters agree, with 1 more left out because at least one datasheet does not publish it. 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.

Questions about this pairing

Which panel is better: IBC Solar IBC Module Black 455 LS-TA2 or IBC Solar Black 455 LS-TA2?
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 Black 455 LS-TA2 and IBC Solar Black 455 LS-TA2?
IBC Solar IBC Module Black 455 LS-TA2 has a module efficiency of 22.80%, while IBC Solar Black 455 LS-TA2 is 22.80%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does IBC Solar IBC Module Black 455 LS-TA2 use vs IBC Solar Black 455 LS-TA2?
IBC Solar IBC Module Black 455 LS-TA2 uses TOPCon cells; IBC Solar Black 455 LS-TA2 uses Monocrystalline. 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 Black 455 LS-TA2 and IBC Solar Black 455 LS-TA2?
IBC Solar IBC Module Black 455 LS-TA2 has a 30 years power warranty; IBC Solar Black 455 LS-TA2 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 IBC Solar IBC Module Black 455 LS-TA2 and IBC Solar Black 455 LS-TA2 bifacial panels?
Both IBC Solar IBC Module Black 455 LS-TA2 and IBC Solar Black 455 LS-TA2 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.
