Photovoltaics

Photovoltaics (phōs = light, voltaic = a unit of electro-motive force) are best known as a method for generating electric power by using solar cells to convert energy from the sun into electricity (the photovoltaic effect).

How is power from solar light produced?

Solar light is composed by photons (light particles). Solar cells are composed by silicon, which contains elementary particles (protons, neutrons and electrons). The photovoltaic effect refers to photons of light knocking electrons into a higher state of energy to create electricity.

Solar cells produce direct current electricity from light, which can be used to power equipment.

A photovoltaic module is composed of individual PV cells. This crystalline-silicon module has an aluminum frame and a solar glass on the front.

	Solar generator (solar modules which create direct current)
	Fixing system
	Cabling
	Disconnect switch (inverter / generator with separator in case of service and repair)
	Inverter (for commuting direct current into alternating current - DC to AC)
	Feed-in counter (for counting the quantity of the fed-in energy)
	System monitoring (i.e. pc or mobile)
