Monocrystalline modules are made of monocrystalline silicon, also known als mono-Si. The silicon is melted and cast into cylindrical ingots to manufacture the individual solar cells. The resulting silicon chrystal is made up out of only one chrystal, hence the term monochrystalline. Monocrystalline panels are easily recognized by their distinctive diamond pattern and black surface. Due to their efficieny, these panels are often used on smaller surfaces.
