4 FAQs about Polycrystalline silicon and monocrystalline silicon solar panels

What is the difference between monocrystalline and polycrystalline solar panels?

Both monocrystalline and polycrystalline solar panels consist of silicon-based photovoltaic (PV) cells. The difference is in the form of silicon within the PV cell. As their names suggest, monocrystalline PV cells are made using a single silicon crystal, whereas polycrystalline PV cells contain many silicon crystals.

What is a polycrystalline solar cell?

Polycrystalline solar cells are also called "multi-crystalline" or many-crystal silicon. Polycrystalline solar panels generally have lower efficiencies than monocrystalline cell options because there are many more crystals in each cell, meaning less freedom for the electrons to move.

How are polycrystalline solar panels made?

Polycrystalline solar panels are made from many fragments of disorganised silicon crystals. Crystalline silicon ingots are formed by cooling molten silicon. The silicon naturally forms a fragmented, disordered structure as it cools. The formed silicon ingots are then cut into thin wafers that are used to make polycrystalline solar panels.

Is polycrystalline silicon better than monocrystalline?

While the efficient manufacturing process for polycrystalline silicon is attractive, the drop in power transfer compared to monocrystalline cells might be an unjustifiable sacrifice depending on the application. For example, monocrystalline modules are ideal for residential or rooftop applications where space is strictly limited.
