There are three types of technology utilized in the manufacture of solar panels. In other words, the solar panels available in the alternative power industry market come in three different forms, namely, monocrystalline, polycrystalline, and thin film amorphous. The main difference between the types are given in their names.
Almost 90% of solar panels in the world are made from silicon. Monocrystalline and Polycrystalline, as suggested by their names, are both types of solar cells that are made from crystalline silicon. The remaining 10%, otherwise the thin film amorphous, are made from the non-crystalline form of silicon.
For definition purposes, a crystalline solid has its particles arranged in a very orderly and repeating three-dimensional pattern. The best example of a crystalline solid is salt. On the other hand, amorphous solids rigid structures but they lack a well-defined shape or pattern. The most common example of an amorphous solid is glass. Gels, plastics, various polymers, wax and thin films are also good examples of amorphous solids.
Monocrystalline Solar Panels
This is the oldest and most developed of the three technologies. They are generally regarded as as the premium in solar panels. Also described by industry practitioners and dealers as ‘mono’, monocrystalline panels, as the name prefix ‘mono’ implies, are created from a single crystal structure continuously repeated. They are thus regarded as pure.
There are fewer crystals in each cell and therefore more freedom for electron movement and higher electricity production.
