There are commonly two type of solar panels

The function of both the monocrystalline and polycrystalline solar panels is same-they turn solar energy into electricity.Generally,Silicon is the common material which is used to manufacture both the solar panels as it is found in abundant.Some solar panel manufacturers produce either monocrystalline solar panel or polycrystalline solar panel.Some produce both.USolar provide service for both the solar panels.
There are many aspects that we should consider before buying solar panels.

MONOCRYSTALLINE SOLAR PANELS

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 10-15% more efficient than their polycrystalline counterparts. Monocrystalline panels also feature a lower temperature coefficient, which means that as the panels get hotter, they will typically outperform their polycrystalline counterparts.

POLYCRYSTALLINE SOLAR PANELS
Polycrystalline solar panels are also made from silicon. However, instead of using a single crystal of silicon, manufacturers melt many fragments of silicon together to form the wafers for the panel. 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.
