It is the heart of the solar power plant. Solar panels consists a number of solar cells.
It is the energy generating unit, made up of p-type and n-type silicon semiconductor

Polycrystalline (sometimes also called multicrystalline) solar panels are the most common because they are often the least expensive.
Polycrystalline solar panels generally have lower efficiencies than monocrystalline options, but their advantage is a lower price point. In addition, polycrystalline solar panels tend to have a blue hue instead of the black hue of monocrystalline panels.
Polycrystalline solar panels are also referred to as “multi-crystalline,” or many-crystal silicon. Because there are many crystals in each cell, there is to less freedom for the electrons to move. As a result, polycrystalline solar panels have lower efficiency ratings than monocrystalline panels.
A Polycrystalline solar panel is made up from multiple crystals, this is often given away by the somewhat mosaic like the appearance of the panels. This is because of the different crystals which make up the module. Other types of panels such as Monocrystalline use just the one crystal, hence the term “mono”. Amorphous uses a single piece of thin film material.
Polycrystalline solar panels are less efficient than those made from a single crystal. However, they are much simpler to produce and cost far less to manufacture. Which in turn is passed onto consumers, meaning they are also much cheaper to buy at the market. The durability and longevity are however indifferent and unaffected by the difference in crystal formation. Polycrystalline could put solar panels into the hands of consumers that cannot afford the Monocrystalline alternatives.
Polycrystalline modules are fitted in much the same way as any other panel and do not incur extra charges as a result of being of a different crystal composition. At this point, we could list a bunch of disadvantages to the consumer by choosing Polycrystalline panels over Monocrystalline,


1. Lower per panel costs
2. Durability and Longevity
3. Environmental Enhancements
4. Lower Electric Bills

Monocrystalline solar panels are generally thought of as a premium solar product. The main advantage of monocrystalline panels is higher efficiency.
To make solar cells for monocrystalline solar panels, silicon is formed into bars and cut into wafers. These types of panels are called “monocrystalline” to indicate that the silicon used is single-crystal silicon. Because the cell is composed of a single crystal, the electrons that generate a flow of electricity have more room to move. As a result, monocrystalline panels are more efficient than their polycrystalline counterparts.
Monocrystalline solar cells are the most popular option on the market, as well as the most efficient form of the solar cell. While they also tend to be the more expensive option, with monocrystalline cells you are guaranteed decent levels of efficiency in all weather conditions, making them a great option. Here is some further information on these solar panels, helping you to decide which are best for you.

These solar cells are also referred to as single crystalline cells. They are easily identifiable by their deep black colour and cut edges. Monocrystalline solar cells are also made from a very pure form of silicon, making them the most efficient material when it comes to the conversion of sunlight into energy.
Additionally, monocrystalline solar cells are also the most space-efficient form of silicon solar cell. In fact, they take up the least space of any solar panel technology that is currently on the market. They also have the great advantage of being the longest lasting solar cell technology, with their life expectancy currently set at around half a century. As a result of this, you will find that the majority of manufacturers will offer you warranties of up to 25 years on these solar panels, lasting half of their expected lifetime.
While this system does remain superior in practically every way when compared to alternative models, it does come with a hefty price tag. Monocrystalline solar cells are considered to be the most expensive option out of all the solar cell types. This is mainly due to the fact that each of the four sides is cut, which results in quite a large amount of waste. This is why polycrystalline acts as a cheaper alternative.
