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

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

IBC Solar Black 450 LS-TA2 has a module efficiency of 22.50%, while IBC Solar IBC Module 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 Black 450 LS-TA2 use vs IBC Solar IBC Module Black 450 LS-TA2?

IBC Solar Black 450 LS-TA2 uses Monocrystalline cells; IBC Solar IBC Module Black 450 LS-TA2 uses TOPCon. 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 Black 450 LS-TA2 and IBC Solar IBC Module Black 450 LS-TA2?

IBC Solar Black 450 LS-TA2 has a 30 years power warranty; IBC Solar IBC Module 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 Black 450 LS-TA2 and IBC Solar IBC Module Black 450 LS-TA2 bifacial panels?

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

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 actually differs

0 of 18 parameters

Every comparable parameter agrees. The full specification is below.

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.
