Monocrystalline Vs. Polycrystalline Solar Panels: What's Different?

Monocrystalline Vs. Polycrystalline Solar Panels: What's Different?

Both these techs have now become integral to many applications. As a matter of fact, they perfectly complement each other but they differ in terms of efficiencies, prices and functions. The monocrystalline panel, which is distinguished by its black-colored cells and higher efficiency, is usually more expensive. However, the polycrystalline ones, which are identifiable by the blue color of the cells, are considered the cheaper ones. In this article, we will address the differences between the two types, the efficiency levels of each, the costs involved and more.

Polycrystalline VS. Monocrystalline Solar Panel Definition

Both types serve the same function: they gather sunlight and then turn it into electricity. Nonetheless, they distinctively vary in the process of their manufacture and their energy utilization efficiencies, which we will look at in this part.

  • Monocrystalline

These ones, typically in their black-colored cells, are made of silicon crystals only. The word “mono” means single, and these collectors are called so because they are made from a dedicated pure crystal structure. The making of these options requires the cutting of the single crystal into wafers. Thanks to this unique feature, electricity can move freely and without obstacles through the collector and this improves the efficiency of monocrystalline daylight cells.

The panels are the most well-known for their higher efficiency. In a 'mono' cell, that is made of one single crystal, the electrons have a lot more space to move about. This in turn means you will be able to produce the same amount of energy with fewer 'mono' collectors on your roof than other options. But these are not always cheap choices.

  • Polycrystalline

These ones, sometimes referred to as multi-crystalline collectors, are easy to identify by their dark blue colored cells. They consist of many silicon crystals. In this context, the term “poly” refers to many, and the collectors are called that because they are filled up with silicon cells having a variety of structures. Multiple small silicon pieces are joined to build the polycrystalline silicon wafers that are used in these collectors.

In addition, they are considered as the cost-effective option. Their efficiency may be slightly lower than that of monocrystalline cases, but they provide a good cost-to-benefit ratio. They are highly stable and are resistant to all types of weather patterns, which makes them fit for any application. Moreover, they are less expensive than monocrystalline choices, which is an advantage for those people who may be on a tighter budget and wish to install solar power.

In summary, both choices have their intrinsic characteristics that are proper for different cases. Sometimes the decision boils down to personal likes, finances and power consumption needs.

Polycrystalline VS. Monocrystalline Solar Panel: What's Different?

Let’s get into an in-depth analysis at the differences and similarities of these collectors.

  • Appearance

Monocrystalline options are definitely recognizable by the black color. The black uniform represents the very high purity of the silicon utilized. Meanwhile, polycrystalline cases are bluish and are of fragmented appearance. It is due to the fact that they are composed of the silicon fragments melted together.

  • Efficiency

Efficiency means how much solar panels can convert sunlight into electricity. Monocrystalline choices have a significantly better conversion efficiency of about 15-20 %. This is possible as a result of the fact that they are drawn from a single crystal configuration that does not impede an unrestricted flow of electricity.

Contrary to that, polycrystalline options have a bit lower efficiency ratings, ranging from 13% to 16%. Many different crystal structures present in such panels result in impediments that interrupt the flow of electricity causing them to be less efficient.

  • Temperature Coefficient

This is a measure of how much the power output of a collector falls as the temperature increases. Mono cases with a lower coefficient tend to function better at higher temperatures. The power output of poly collectors has higher coefficients as compared with mono options, which means they will have more losses as the temperature rises.

  • Lifespan

Both options have a long life span, but the differences exist. The average lifespan for mono collectors is between 30 to 40 years when sufficient maintenance and care are provided. Poly choices, like mono, are also durable, but they are usually good for about 25 –35 years.

  • Cost

As far as cost is concerned, the Poly expenses are usually less expensive than the Mono ones. As for the Poly, they are priced between $0.90 and $1 each, and as for the Monocrystalline options, they normally cost between $1 and $1.50 per watt. To the contrary, however, the cost of Mono collectors is higher at the initial phase but the higher efficiency and longevity can give rise to substantial savings eventually.

Polycrystalline VS. Monocrystalline Solar Panel Applications

The two have made their mark in multiple areas such as using them in residential rooftops to large scale solar farms. So, let’s have a look at the applications of these two types.

  • Monocrystalline

This option, more efficient than any other type of panel, can produce the same amount of electricity over a given area occupied by collectors of other materials. This renders them therefore quite massively to be explored by people who are off-grid as well as households with solar rooftops both in urban and rural areas.

These collectors are to be used for larger projects, most preferably in the remote areas, where cultivable land is not an issue. Such higher efficiency gives them perfect match for large installations where space is an issue.

The small monocrystalline collectors producing between 5 and 25W power are sufficiently efficient to charge phones, cameras, and laptops. As a result, they are perfect for small-size applications where efficiency is more critical than cost.

  • Polycrystalline

These have the advantage that they can be installed on roof-mounted arrays. Their blue color and the shardlike figure make them harder to spot on roofs, so they are the top pick for the residential installations.

They help to collect the power of the sun for use in large solar farms supplying electricity to the vicinity. The cost-efficiency of these collectors makes them suitable for large-scale installations where upfront investment cost is a major consideration.

They are also used in standalone or self-powered systems like traffic lights in remote places, isolated households, etc. Their durability and temperature tolerance make them appropriate for such applications.
