AWG stands for "American Wire Gauge" being this a measure used to represent the width and section measurements of cables.

Here is an AWG conversion table:

AWG	Diam. mm	Mm2 area		AWG	Diam. mm	Mm2 area
1	7.35	42.40		16	1.29	1.31
two	6.54	33.60		17	1.15	1.04

Photovoltaic energy is produced by solar radiation using devices called photovoltaic cells. It is ideal for supplying all kinds of isolated houses, shelters, but also can be used to supply electricity on a large scale. We show the operating principle "In a semiconductor exposed to light, a photon of energy starts an electron, creating both a" gap "in the atom excitador. Normally, the electron quickly finds another hole to refill it, and the energy provided by the photon thus dissipates as heat. The principle of a photovoltaic cell is to force the electrons and holes to move towards the opposite side of the material rather than simply recombine in it: thus, there will be a potential difference and thus tension between the two sides of the material,as in a stack "The first ground application of a commercial installation of photovoltaic cell was developed in Japan in 1966.
