The choice between crystalline and amorphous solar panels may seem obvious, until you do a little more research. At first glance, it seems that amorphous ones are the better option, but this is not necessarily so.

An amorphous solar panel does cost less and it is more difficult to break and it does use less silicon. All of these things are true, but one major problem with them is that they generally have a lower power output. To get the same power output, more amorphous panels are needed, meaning that the array takes up more space. Also, an amorphous panel will likely deteriorate more quickly than its crystalline counterpart.

There are both monocrystalline and polycrystalline solar cells. Monocrystalline cells are very efficient – a given area produces more electricity than that of other forms. Unfortunately, these cells are made from slices of large silicon crystals, and they can be rather expensive. Polycrystalline cells are less expensive, but also slightly less efficient.

The technology for all types of solar panels is improving, and there are also some being developed that do not use silicon at all.
