IBC Solar IBC Module Black 455 LS-TA2 vs IBC Solar Black 450 LS-TA2

Q: Which panel is better: IBC Solar IBC Module Black 455 LS-TA2 or IBC Solar Black 450 LS-TA2?

According to our database: IBC Solar IBC Module Black 455 LS-TA2 has higher module efficiency (22.80% vs 22.50%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of IBC Solar IBC Module Black 455 LS-TA2 and IBC Solar Black 450 LS-TA2?

IBC Solar IBC Module Black 455 LS-TA2 has a module efficiency of 22.80%, while IBC Solar Black 450 LS-TA2 is 22.50%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does IBC Solar IBC Module Black 455 LS-TA2 use vs IBC Solar Black 450 LS-TA2?

IBC Solar IBC Module Black 455 LS-TA2 uses TOPCon cells; IBC Solar Black 450 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.

Q: What is the warranty on IBC Solar IBC Module Black 455 LS-TA2 and IBC Solar Black 450 LS-TA2?

IBC Solar IBC Module Black 455 LS-TA2 has a 30 years power warranty; IBC Solar Black 450 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.

Q: Are IBC Solar IBC Module Black 455 LS-TA2 and IBC Solar Black 450 LS-TA2 bifacial panels?

Both IBC Solar IBC Module Black 455 LS-TA2 and IBC Solar Black 450 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.

What it means on a roof

Thirty years of production

Each panel's own declared degradation curve, at 1,200 kWh/kWp a year

Cell temperature

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.
