Type of Solar Panel

Best Solar Panels Perth

Solar panel technology has steadily improved over the last few decades, becoming both cheaper and more efficient. There are generally three classes of solar panel used in homes (as well as a few more expensive types only used for scientific purposes).

The three standard classes of solar panel used in most homes and industries are Polycrystalline, Monocrystalline and the more recent thin film amorphous.


This is the oldest class of solar panel still in use. They work with silicone manufactured to be a single crystal structure.

This produces a fairly efficient solar panel, the downside being that a fair amount of silicon is wasted in the manufacturing process. So the panels are rather expensive.

Monocrystalline panels have a distinctive appearance, being a uniform flat black colour.

Polycrystalline (also called Multicrystalline)

This is more recent technology, being put into use over the last few years. They are slightly less efficient than monocrystalline, and lose a little more efficiency in hot conditions, but they are far cheaper to produce. So it is often better/cheaper to use a larger number of polycrystalline panels than a smaller number of monocrystalline panels. Three polycrystalline panels would produce more power than then two monocrystaline panels, and cost less.

Polycrystalline panels have become the most popular choice over the past few years. As long as there is sufficient space there is no reason to prefer monocrystalline panels. And the performance of polycrystalline panels is fast approaching the performance of monocrystalline.

Polycrystalline panels have a less regular appearance than flat, uniform monocrystalline panels.

Thin Film Amorphous

This is very recent technology, but it is rapidly improving. Presently these panels are less efficient than crystalline panels, but they are also far less expensive. They are predicted to have similar efficiency to crystalline panels (about 20%) within a decade

Thin film solar panels are less effected by shade and high temperatures; their performance is reasonably constant under changing conditions. They are also physically flexible and quite neat looking. But they take up more space that crystalline panels, and may have a short lifespan.

This may be the more popular solar panel in about a decade’s time.

Commercial Solar Power Perth

Solar panels are a good option for your home. As long as there is reasonable space on the roof (where they are out of the way) they can provide years of free electricity for a home once the initial investment is made.
