Difference Between Monocrystalline and Polycrystalline Solar Panels

Feature

Monocrystalline

Polycrystalline

Material

Made from a single crystal of silicon (pure, continuous structure)

Made from multiple silicon crystals melted together

Color / Appearance

Black color, uniform look

Bluish color, with visible grain or fragments

Efficiency

Higher (typically 18–22%) due to better electron flow

Lower (typically 15–18%) because of crystal boundaries

Space Requirement

Produces more power per area — better for limited roof space

Needs more area for same power output

Performance in Low Light / High Temp

Performs better in low light and high temperature

Slightly less efficient in such conditions

Cost

More expensive (due to complex manufacturing)

Cheaper (simpler to produce)

Lifespan

Long (often 25–30 years)

Also long, but may degrade slightly faster

Typical Use

Homes or businesses needing maximum efficiency in limited space

Large-scale or budget-sensitive installations with ample area
