IBC Solar YH720W-33MHD/MH vs IBC Solar White 455 MS-TA1

Q: Which panel is better: IBC Solar YH720W-33MHD/MH or IBC Solar White 455 MS-TA1?

According to our database: IBC Solar YH720W-33MHD/MH has higher module efficiency (23.18% vs 22.77%); IBC Solar White 455 MS-TA1 tolerates heat better (temp coeff -0.300%/°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 YH720W-33MHD/MH and IBC Solar White 455 MS-TA1?

IBC Solar YH720W-33MHD/MH has a module efficiency of 23.18%, 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.

Q: What cell technology does IBC Solar YH720W-33MHD/MH use vs IBC Solar White 455 MS-TA1?

IBC Solar YH720W-33MHD/MH 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.

Q: What is the warranty on IBC Solar YH720W-33MHD/MH and IBC Solar White 455 MS-TA1?

IBC Solar YH720W-33MHD/MH 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.

Q: Are IBC Solar YH720W-33MHD/MH and IBC Solar White 455 MS-TA1 bifacial panels?

IBC Solar YH720W-33MHD/MH is bifacial (captures light from both faces); IBC Solar White 455 MS-TA1 is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
