A solar panel is a device used to convert solar thermal energy into electrical energy. The conversion process can occur because there are solar cells in the solar panel. These solar cells then generate electricity through a process called the photovoltaic system. Based on the material that makes up the solar panels, solar cells are categorized into monocrystalline silicon solar panels and polycrystalline silicon solar panels.
This article will discuss monocrystalline silicon, including how it works. Check out the full explanation below!
What is a Monocrystalline Silicon Solar Panel?
Monocrystalline silicon solar panels are a type of solar panel composed of solar cells made from high-purity silicon crystals. The silicon crystals are cut to form thin cylindrical bars. The name “monocrystalline” is used because these solar cells use a single (mono) silicon crystal.
The single crystal allows electrons to move more freely. As a result, the flow of electricity is even better. Compared to other types of solar panels, monocrystalline can achieve an efficiency level of more than 20%. The cylindrical rods of monocrystalline silicon are arranged to form an octagon and maximize the utility of the solar cell.
What Is The Difference Between Monocrystalline Silicon and Polycrystalline Silicon?
How do we distinguish monocrystalline silicon from polycrystalline silicon? The fundamental difference lies in the number of silicon crystals used. If monocrystalline only uses a single silicon crystal, polycrystalline uses several silicon crystal fragments.
However, the most easily recognizable difference lies in the outer appearance of the two solar panels. Monocrystalline usually has a black color, while polycrystalline is blue. So is the shape; monocrystalline is octagonal, and polycrystalline has a square shape that is equipped with solar cell fragments.
The two types of solar panels are also different in terms of efficiency. Monocrystalline is a solar panel with the highest efficiency level that reaches more than 20%. Meanwhile, the efficiency of polycrystalline “only” reaches 17%. However, polycrystalline is relatively more affordable than monocrystalline in terms of price.
How Does Solar Panels Work?
A solar panel is a device that works by utilizing photons or light particles from the sun. Solar panels push photons to drop free electrons from atoms to generate electricity.
There is a series of small components in a solar panel called photovoltaic cells. These cells then convert energy from the sun into electrical energy. After the solar panel generates electrical power, the device will directly forward it to the connected electricity network.
How does Monocrystalline Silicon Solar Panels work?
So, what about monocrystalline silicon solar panels? Do these solar panels have a different way of working to achieve high efficiency?
When sunlight falls on a monocrystalline solar panel, the photovoltaic cells will immediately absorb energy. With a complicated process, the cells then create an electric field.
The electric field created by monocrystalline photovoltaic cells consists of voltage and electric current to produce electric power. If made into an equation, it will look like this:
Power (P) = Voltage (V) x Current (I)
We can directly use the power generated from the electric field in an electric network that applies direct current (DC). However, the power can also be processed first with an inverter to turn it into an alternating current (AC).
Now you know what a monocrystalline silicon solar panel is. This type of solar panel is made of single-crystal silicon with a high purity level. Monocrystalline is more efficient than other solar panels since it produces higher power output (up to 20%).
Solar panels are one type of renewable electrical energy source that is environmentally friendly. The device does not produce carbon emissions by converting solar energy into electricity. In addition to solar panels, there are also renewable sources of electrical energy that are more environmentally friendly.
