Solar Panel Types

Monocrystalline Solar Panels

Monocrystalline solar panels have the highest efficiency rates, and also have high life time vlaue.
Monocrystalline Solar Panels are made from a single continuous crystal structure a silicon crystal ‘seed’ is placed in a vat of molten silicon. The seed is then slowly drawn up with the molten silicon forming a solid crystal structure around the seed known as an ingot. The ingot of solid crystal silicon that is formed is then finely sliced ingot what is known as a silicon wafer. This is then made into a cell.

Monocrystalline Solar panels have Efficiency-Rate of up to 22% they are optimised for commercial use and have high life-time value.

Polycrystalline Solar Panels

Polycrystalline Solar panels have Efficiency-Rate of up to 19%.
Polycrystalline also start as a silicon crystal ‘seed’ placed in a vat of molten silicon. However, rather than draw the silicon crystal seed up as with Monocrystalline the vat of silicon is simply allowed to cool. This is what forms the distinctive edges and grains in the solar cell.
Polycrystalline cells were previously thought to be inferior to Monocrystalline because they were slightly less efficient, however, because of the cheaper method by which they can be produced coupled with only slightly lower efficiencies they have become the dominant technology on the residential solar panels market.

Polycrystalline Solar panels have Efficiency-Rate of up to 19%. Thay have Very affordable price with more demand in the market they are now the main streamed solar panels.

Thin-Film: Amorphous Silicon Solar Panels

Thin-Film: Amorphous Silicon Solar Panels
Thin film panels are a totally different technology to Mono and Polycrystalline panels. They are a new technology compared to Mono and Polycrystalline cells and would not be considered a mature technology as vast improvements in this technology are expected in the next 10 years.
A thin film panel can be identified as having a solid black appearance. They may or may not have a frame, if the panel has no frame it is a thin film panel.
Thin film panels are made by depositing a photovoltaic substance onto a solid surface like glass. The photovoltaic substance that is used varies and multiple combinations of substances have successfully and commercially been used.
