Poly Solar Panel Definition

Polycrystalline solar panels are also made from silicon.

Poly solar panel definition.

Up until a few years ago most solar panels were monocrystalline but in the last three years polycrystalline solar panels have overtaken them as the most commonly used panel. Sustainability of construction materials 2009. Polycrystalline solar panels are getting their due. Both mono and poly solar panels are made of silicon have silicon molded into crystalline forms but there are some major differences between the two types and each has their advantages and disadvantages.

Polycrystalline silicon or multicrystalline silicon also called polysilicon or poly si is a high purity polycrystalline form of silicon used as a raw material by the solar photovoltaic and electronics industry. This process involves distillation of volatile silicon compounds and their decomposition into silicon at high temperatures. Polysilicon is produced from metallurgical grade silicon by a chemical purification process called the siemens process. Composition of mono and poly solar cells in case of monocrystalline cell each cell is made of one piece of silicon crystal.

An emerging alternative process of re. 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. They were thought of as inferior and not able to attain the efficiency of monocrystalline solar panels.

Polycrystalline cells are formed of liquid silicon which is poured into blocks which are then cut into plates.
