Both Monocrystalline and Polycrystalline Solar PV Panels are made from Silicon
The main difference between the two technologies is the type of silicon solar cell they use: monocrystalline solar panels have solar cells made from a single crystal of silicon, while polycrystalline solar panels have solar cells made from silicon fragments melted together.
Monocrystalline solar panels
The main advantages of monocrystalline solar panels are higher efficiencies.
Silicon is formed into bars and cut into wafers to manufacture the cells for monocrystalline solar panels. These panels are called “monocrystalline” to indicate that the silicon used is single-crystal silicon. Because cells are made of a single crystal, the electrons have more room to move to generate a flow of electricity. Therefore, monocrystalline PV panels are more efficient than polycrystalline PV panels.
