IBC Solar YH210W-21M vs IBC Solar YH205W-21M

Q: Which panel is better: IBC Solar YH210W-21M or IBC Solar YH205W-21M?

According to our database: IBC Solar YH210W-21M has higher module efficiency (20.35% vs 19.86%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of IBC Solar YH210W-21M and IBC Solar YH205W-21M?

IBC Solar YH210W-21M has a module efficiency of 20.35%, while IBC Solar YH205W-21M is 19.86%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does IBC Solar YH210W-21M use vs IBC Solar YH205W-21M?

IBC Solar YH210W-21M uses PERC cells; IBC Solar YH205W-21M 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 YH210W-21M and IBC Solar YH205W-21M?

IBC Solar YH210W-21M has a 30 years power warranty; IBC Solar YH205W-21M 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.

What it means on a roof

Thirty years of production

Declared first-year losses, with 0.40% a year afterwards assumed for both panels, at 1,200 kWh/kWp a year

Cell temperature

Same temp coeff. for both panels (-0.340 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.
