Photovoltaic effect :
The photovoltaic effect represents the phenomenon when a particular material exposed to light generates an electrical tension. This phenomenon is obtained thanks to the absorption of the bright rays in a material called “semi-conductor”; the most common example is silicon. The tension produced at the terminals of the “semi-conductor” can be collected by two terminals. We obtain the passage of a direct current in an electrical circuit.
Orientation in relation with the sun :
The energy picked up by a photovoltaic panel is maximum when the solar rays strike the surface of the panel in a perpendicular way. Any drift, in relation with the perpendicular, drives to a reduction of the energy picked up by the photovoltaic panel.
From 30 ° of error, loss becomes noticeable.
So we understand that the orientation of the panel has a key importance on its energy production.
