IBC Solar YH545W-36MH vs IBC Solar YH720W-33MHD/MH

Q: Which panel is better: IBC Solar YH545W-36MH or IBC Solar YH720W-33MHD/MH?

According to our database: IBC Solar YH720W-33MHD/MH has higher module efficiency (23.18% vs 21.09%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of IBC Solar YH545W-36MH and IBC Solar YH720W-33MHD/MH?

IBC Solar YH545W-36MH has a module efficiency of 21.09%, 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 YH545W-36MH use vs IBC Solar YH720W-33MHD/MH?

IBC Solar YH545W-36MH uses PERC 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 YH545W-36MH and IBC Solar YH720W-33MHD/MH?

IBC Solar YH545W-36MH 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 YH545W-36MH and IBC Solar YH720W-33MHD/MH bifacial panels?

IBC Solar YH720W-33MHD/MH 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.

What it means on a roof

Thirty years of production

A 1.0% first-year loss then 0.40% a year, assumed for both panels, at 1,200 kWh/kWp a year

Cell temperature

Same temp coeff. for both panels (-0.350 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.
