How many types of panel are there ?
Currently there are three type of PV panel in the market place :
Monocrystalline Solar Panels :
Monocrystalline solar panels are made from a large crystal of silicon. These type of solar panels are the most efficient as in absorbing sunlight and converting it into electricity, however they are the most expensive. They do somewhat better in lower light conditions then the other types of solar panels.
Polycrystalline Solar Panels :
Polycrystalline solar panels are the most common type of solar panels on the market today. They look a lot like shattered glass. They are slightly less efficient then the monocrystalline solar panels.
Amorphous Solar Panels :
Amorphous solar panels consist of a thin-like film made from molten silicon that is spread directly across large plates of stainless steel or similar material. These types of solar panels have lower efficiency then the other two types of solar panels. One advantage of amorphous solar panels over the other two is that they are shadow protected. That means that the solar panel continues to charge while part of the solar panel cells are in a shadow. These work great on boats and other types of transportation
