POLYCRYSTALLINE SOLAR CELLS VS MONOCRYSTALLINE: WHICH IS BETTER?

MONOCRYSTALLINE SILICON SOLAR CELLS

Solar cells made of monocrystalline silicon are black and very uniform in appearance, which is an indication of their high purity.

Pros:

Monocrystalline solar panels have the highest efficiency rates, typically in the 15-20% range.

This high efficiency rate means they produce more power per square foot, and are therefore very space-efficient.

Monocrystalline solar panels tend to be more efficient in warm weather. Performance suffers somewhat as temperature goes up, but less so than with polycrystalline solar panels.

Since they are monocrystalline and perform better in heat these panels are projected to have the longest life. Most come with a 25-year warranty but will probably last substantially longer than 25 years.

They perform better than similarly rated polycrystalline solar panels at low-light conditions.

Many people find their uniformity and black color more aesthetically pleasing than the blue color and sometimes variegated pattern of the polycrystalline panels.

Cons:

Monocrystalline solar panels cost more than polycrystalline panels. See below for a cost comparison.

POLYCRYSTALLINE SILICON SOLAR CELLS

The first solar panels based on polycrystalline silicon were introduced to the market in 1981. These panels are blue and sometimes have a variegated pattern.

Pros:

The process used to make polycrystalline silicon is simpler and costs less.

Cons:

Polycrystalline panels have lower efficiency rates typically in the 13-16% range. Monocrystalline panels have higher efficiencies in the range of 15-20%.

Because of the lower efficiency rate they are not as space-efficient since they produce less power per square foot.

Polycrystalline panels tend to have lower heat tolerance than monocrystalline solar panels and perform slightly worse than monocrystalline solar panels in high temperatures.

Heat can affect not only the performance of polycrystalline solar panels and but is projected to substantially shorten their lifespan.

These panels are also less efficient in low-light condition.

Polycrystalline panels then to be less aesthetically pleasing since they have a non-uniform look and sometimes a speckled blue color.
