You may have been shopping for solar panels, and come across the terms monocrystalline and polycrystalline. You may have wondered what they are.
Read on for more information.
Differences between Monocrystalline and Polycrystalline Solar Panels
Monocrystalline and polycrystalline panels are solar cells made from crystalline silicon. They are both categories in solar panels, which produce energy from the sun.
They, however, have key differences. To understand them better, pure energies explains in detail types of solar panels below.
Monocrystalline panels have been in the market longest. They comprise of a single continuous crystal structure. The cells, therefore, appear as a single black hue. Polycrystalline panels, on the other hand, comprise of many solar cells containing silicon fragments. The manufacturer melts together during the production process. The final product takes on a blue hue.
The monocrystalline panels are more effective due to the construction. During production, the manufacturer cuts bars out of the silicon. The single-crystal silicon construction gives electronics sufficient room to move, thus more efficiency in the production of electricity. They are also ideal in low light and high heat environments.
Polycrystalline solar panels comprise of silicon fragments bound together through melting. The many-crystal composition results in less space for the crystals to move. The congestion reduces the overall efficiency of the panel.
Monocrystalline panels are more expensive than polycrystalline due to the production process. A lot of waste occurs in manufacturing the former due to the shaving of silicon to the desired shape. Polycrystalline is less wasteful because of the melting together of the fragments, so there is hardly any wastage.
Determining the kind of panel to buy depends on your needs and specifications as per the project. It is critical that you seek expert advice so that you make the right choice on the type of panels you buy.
