Each type has its own unique advantages and disadvantages, and the solar panel type best suited for your installation will depend on factors specific to your own property and desired system characteristics.

To produce electricity, solar cells are made from a semiconducting material that converts light into electricity. The most common material used as a semiconductor during the solar cell manufacturing process is silicon. Both monocrystalline and polycrystalline solar panels have cells made of silicon wafers. To build a monocrystalline or polycrystalline panel, wafers are assembled into rows and columns to form a rectangle, covered with a glass sheet, and framed together.

While both of these types of solar panels have cells made from silicon, monocrystalline and polycrystalline panels vary in the composition of the silicon itself. Monocrystalline solar cells are cut from a single, pure crystal of silicon. Alternatively, polycrystalline solar cells are composed of fragments of silicon crystals that are melted together in a mold before being cut into wafers. Unlike monocrystalline and polycrystalline solar panels, thin-film panels are made from a variety of materials.

The most prevalent type of thin-film solar panel is made from cadmium telluride CdTe. To make this type of thin-film panel, manufacturers place a layer of CdTe between transparent conducting layers that help capture sunlight. This type of thin-film technology also has a glass layer on the top for protection. Thin-film solar panels can also be made from amorphous silicon a-Si , which is similar to the composition of monocrystalline and polycrystalline panels. Though these thin-film panels use silicon in their composition, they are not made up of solid silicon wafers.

CIGS panels have all four elements placed between two conductive layers i. The differences in materials and production cause differences in appearance between each type of solar panel:.

These cells appear black because of how light interacts with the pure silicon crystal. While the solar cells themselves are black, monocrystalline solar panels have a variety of colors for their back sheets and frames.

The back sheet of the solar panel will most often be black, silver or white, while the metal frames are typically black or silver. Unlike monocrystalline solar cells, polycrystalline solar cells tend to have a bluish hue to them due to the light reflecting off the silicon fragments in the cell in a different way than it reflects off a pure monocrystalline silicon wafer.

Similar to monocrystalline, polycrystalline panels have different colors for back sheets and frames. Most often, the frames of polycrystalline panels are silver, and the back sheets are either silver or white. The biggest differentiating aesthetic factor when it comes to thin-film solar panels is how thin and low-profile the technology is.

As their name suggests, thin-film panels are often slimmer than other panel ty[es. This is because the cells within the panels are roughly times thinner than the crystalline wafers used in monocrystalline and polycrystalline solar panels. There are adhesive thin-film solar panels that lie as-close-as-possible to the surface of a roof, but there are more durable thin-film panels that have frames up to 50 millimeters thick.

Only the first two technologies — monocrystalline and polycrystalline — are available in Australia these days. Thin film is no longer used here for residential installations.

The following are some details on each type of technology, including thin film just for general interest purposes:. Monocrystalline is one of the oldest technologies, and more expensive to make, but this type have the highest efficiency.

They are made from wine-bottle sized single crystals of ultra-pure silicon and sliced up like salami to make individual wafers. The silver lines are wires that collect the electricity that is created when light hits the cell. The solar panel is made up of a matrix of these moncrystalline solar cells laid flat — like tiles on your bathroom floor:. Monocrystalline solar cells are generally high performance, but because they waste a bit of space between the cells when they are encapsulated in a solar PV panel the little white diamonds in the picture above they perform about the same in efficiency and power terms as polycrystalline.

The easy way to spot mono solar panels on a roof is to look for the tell tale white diamonds between the cells.
