IBC Solar YH550W-36MH vs IBC Solar YH545W-36MH

Q: Which panel is better: IBC Solar YH550W-36MH or IBC Solar YH545W-36MH?

According to our database: IBC Solar YH550W-36MH has higher module efficiency (21.28% 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 YH550W-36MH and IBC Solar YH545W-36MH?

IBC Solar YH550W-36MH has a module efficiency of 21.28%, 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 YH550W-36MH use vs IBC Solar YH545W-36MH?

IBC Solar YH550W-36MH uses PERC 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 YH550W-36MH and IBC Solar YH545W-36MH?

IBC Solar YH550W-36MH 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.

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.

Every comparable parameter agrees. The full specification is below.

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.
