Monocrystalline vs Polycrystalline Solar Cells: Which is the Best Option?

Monocrystalline and polycrystalllne solar cells are two common types of solar cells on today's market. Learn about their differences in efficiency, cost and performance.

Monocrystalline vs Polycrystalline Solar Cells: Which is the Best Option?

When it comes to solar cells, there are two main types: monocrystalline and polycrystalline. Monocrystalline solar cells are the most premium panel, since they make the most efficient use of the sun's rays. However, polycrystalline panels are less expensive and may be a good option for areas with a lot of sunlight. The main factor that determines the difference in costs between these two types of solar panels is the silicon structure.

To produce polycrystalline panels, manufacturers pour molten silicon into square molds and then cut the resulting wafers into individual cells. On the contrary, to produce monocrystalline panels, the solidification of silicon must be controlled very carefully, which is a more complex process that makes monocrystalline solar cells more expensive. Mono panels are slightly more expensive than polyethylene panels of the same power. Polycrystalline solar panels are less expensive to manufacture than monocrystalline panels, so they may be a cheaper option for some consumers.

They also tend to perform better in hot climates than monocrystalline panels, making them a good choice for those living in sunny climates. Polycrystalline solar panels also have a lower carbon footprint than their monocrystalline counterparts, since they require less energy and resources for production. Polycrystalline solar panels have an efficiency of between 13 and 16%, while monocrystalline panels have an efficiency rate of 15 to 20%. Like efficiency, monocrystalline solar panels tend to outperform polycrystalline models when it comes to temperature coefficient.

While monocrystalline panels tend to be more expensive, some households will find that the total price of the system will be cheaper than if they used polycrystalline panels. Monocrystalline solar panels are made of a single large crystal of silicon, while polycrystalline solar panels are made of many smaller crystals. PERC cell technology is gaining ground because the inclusion of the passivation layer does not entail major delays or manufacturing costs. When considering the lower cost of P-type cells, it is usually worth opting for a cheaper module that degrades slightly more, as opposed to a substantially more expensive panel with slightly less degradation.Unlike a solid-state monocrystalline solar cell, a thin-film solar panel has a narrow spectral response, and the best performance occurs at shorter wavelengths (blue area).

Although these panels are generally considered to be a premium solar product, the main advantages of monocrystalline panels are greater efficiency and a sleeker aesthetic.Monocrystalline and polycrystalline solar panels are the two most common types of solar panels on today's market. The manufacturing process of polycrystalline cells is similar to that of monocrystalline panels, with some key differences. In the production of monocrystalline panels, this is done using a Czochralski process, which results in a single large crystal.Monocrystalline panels are usually more efficient than polycrystalline panels, meaning they can convert more sunlight into electricity. Most solar panels installed today are made of monocrystalline or polycrystalline solar cells.

Although they represent a significantly smaller percentage of the solar panel market (in particular, residential and commercial panels), there are other solar panel options available in addition to monocrystalline and polycrystalline solar cells.
