IBC Solar Transparent 455 LS-TA2 vs IBC Solar YH720W-33MHD/MH

Q: Which panel is better: IBC Solar Transparent 455 LS-TA2 or IBC Solar YH720W-33MHD/MH?

According to our database: IBC Solar YH720W-33MHD/MH has higher module efficiency (23.18% vs 22.80%); IBC Solar Transparent 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 Transparent 455 LS-TA2 and IBC Solar YH720W-33MHD/MH?

IBC Solar Transparent 455 LS-TA2 has a module efficiency of 22.80%, while IBC Solar YH720W-33MHD/MH is 23.18%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does IBC Solar Transparent 455 LS-TA2 use vs IBC Solar YH720W-33MHD/MH?

IBC Solar Transparent 455 LS-TA2 uses Back Contact cells; IBC Solar YH720W-33MHD/MH 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 Transparent 455 LS-TA2 and IBC Solar YH720W-33MHD/MH?

IBC Solar Transparent 455 LS-TA2 has a 30 years power warranty; IBC Solar YH720W-33MHD/MH 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 Transparent 455 LS-TA2 and IBC Solar YH720W-33MHD/MH bifacial panels?

Both IBC Solar Transparent 455 LS-TA2 and IBC Solar YH720W-33MHD/MH 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.
