Photovoltaic module

A solar panel (photovoltaic module or photovoltaic panel) is a packaged, connected assembly of solar cells, also known as photovoltaic cells.

The solar panel can be used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications. Because a single solar panel can produce only a limited amount of power, many installations contain several panels. A photovoltaic system typically includes an array of solar panels, an inverter, and sometimes a battery and interconnection wiring.

Monocrystalline cells are cut from a single crystal of silicon, they are actually a slice of a crystal. Aspect, it is a soft and you can see the slice thickness. These are the most effective and most expensive to produce. They are too rigid and should be mounted on a rigid frame to protect them.

Polycrystalline (or Multicrystalline) cells actually cut a slice of silicon block, consisting of several crystals. They have a mottled appearance of reflection, and yet, you can see the thickness of the disk. These cells are slightly less efficient and less expensive than monocrystalline cells and has yet to be mounted on a rigid frame.
