Thin film technology costs less than mono or poly panels but is also less efficient.
Mono vs poly solar panels shading.
Monocrystalline solar cells have historically had a higher peak efficiency and were more readily available than polysilicon solar cells.
They typically perform better than polycrystalline alternatives albeit by a small amount.
You can find a more in depth comparison of mono vs poly solar panel here.
Monocrystalline solar panels have solar cells made from a single crystal of silicon while polycrystalline solar panels have solar cells made from many silicon fragments melted together.
There were a number of reasons for this thinking.
When solar pv first boomed in australia in 2009 2010 monocrystalline solar panels were thought to be superior to polycrystalline solar panels.
In other words you would need less monocrystalline solar panels in your solar power system to generate the same amount of power that say a greater number of polycrystalline solar panels would.
Polycrystalline silicon solar panels polycrystalline are also known as multi crystalline solar panels and unlike monocrystalline solar panels the melted silicon to produce them is poured into a square mould.
Most panels these days have bypass diodes to help with partial shading so you don t looses all the output.
This silicon is then cooled and finally sliced into square wafers creating the polycrystalline shape.
It is mainly used in large scale commercial applications.
Thin amorphous film panel output is supposed to increase with age and heat where as output on mono poly crystalline panels loose some output with heat and time.
Advantages of mono solar panels.
The older of the two mono panels are the most developed type of photovoltaic panel cells.
The main difference between the two technologies is the type of silicon solar cell they use.
See an example of monocrystalline cells below.
So monocrystalline solar panels will usually have a higher power output rating than either polycrystalline or thin film modules.
N type cells are more resistant to light induced degradation than p type cells.
Polycrystalline solar cells are blended from multiple silicon sources and are slightly less efficient.
Monocrystalline solar cells are more efficient because they are cut from a single source of silicon.
So that briefly covers monocrystalline vs polycrystalline.
Amorphous solar panels.
Mono panels are the most efficient since they re made with high quality silicon.
Looking at mono vs poly solar panels you can see that mono crystalline panels have a smoother more uniform appearance than poly crystalline panels.
