IBC Solar YH710W-33MHD/MH vs IBC Solar YH210W-21M

Q: Which panel is better: IBC Solar YH710W-33MHD/MH or IBC Solar YH210W-21M?

According to our database: IBC Solar YH710W-33MHD/MH has higher module efficiency (22.86% vs 20.35%); IBC Solar YH210W-21M tolerates heat better (temp coeff -0.340%/°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 YH710W-33MHD/MH and IBC Solar YH210W-21M?

IBC Solar YH710W-33MHD/MH has a module efficiency of 22.86%, while IBC Solar YH210W-21M is 20.35%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does IBC Solar YH710W-33MHD/MH use vs IBC Solar YH210W-21M?

IBC Solar YH710W-33MHD/MH uses TOPCon cells; IBC Solar YH210W-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 YH710W-33MHD/MH and IBC Solar YH210W-21M?

IBC Solar YH710W-33MHD/MH has a 30 years power warranty; IBC Solar YH210W-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.

Q: Are IBC Solar YH710W-33MHD/MH and IBC Solar YH210W-21M bifacial panels?

IBC Solar YH710W-33MHD/MH is bifacial (captures light from both faces); IBC Solar YH210W-21M is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
