IBC Solar Black 455 LS-TA2 vs IBC Solar YH545W-36MH

Q: Which panel is better: IBC Solar Black 455 LS-TA2 or IBC Solar YH545W-36MH?

According to our database: IBC Solar Black 455 LS-TA2 has higher module efficiency (22.80% vs 21.09%); IBC Solar Black 455 LS-TA2 tolerates heat better (temp coeff -0.290%/°C vs -0.350%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of IBC Solar Black 455 LS-TA2 and IBC Solar YH545W-36MH?

IBC Solar Black 455 LS-TA2 has a module efficiency of 22.80%, while IBC Solar YH545W-36MH is 21.09%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does IBC Solar Black 455 LS-TA2 use vs IBC Solar YH545W-36MH?

IBC Solar Black 455 LS-TA2 uses Monocrystalline cells; IBC Solar YH545W-36MH uses PERC. 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 455 LS-TA2 and IBC Solar YH545W-36MH?

IBC Solar Black 455 LS-TA2 has a 30 years power warranty; IBC Solar YH545W-36MH 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 455 LS-TA2 and IBC Solar YH545W-36MH bifacial panels?

IBC Solar Black 455 LS-TA2 is bifacial (captures light from both faces); IBC Solar YH545W-36MH is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
