There are two main types of crystalline solar panels
Monocrystalline silicon is a proven technology that has been in use for over 50 years. The solar cells are produced from a single silicon seed crystal placed in a crucible of molten silicon and drawn out slowly while rotating. It is possible to produce a larger pure crystalline silicon ingot which is then sliced into thinner wafers. These typically have a greater efficiency than other types of cells but they are more difficult to manufacture and the cost per watt is higher.
Polycrystalline is a block of material which instead of being a single crystal is made by block casting molten silicon. They are composed of many small crystals which grow in random orientations as the molten material solidifies. This produces slightly lower efficiencies than Monocrystalline cells, however it is easier and less expensive to manufacture.
