Photovoltaic Solar

Photovoltaic (PV) Solar - What You Should Know....

Photovoltaic Solar Power is, in it's simplest definition, the energy created by converting solar energy into electricity using photovoltaic solar cells. Solar power cells are made out of materials known as semiconductors, usually silicon. A semiconductor has the properties of an insulator, but when exposed to light or heat is capable of conducting electricity.

However, in order to generate solar electricity, the silicon used for the semiconductor needs to be treated by a process known as "doping." Doping simply mixes an additional chemical element with the silicon to create either a positively charged or negatively charged layer of silicon.

A solar power cell consists of two layers of this treated silicon. The bottom layer is positively charged (P-type) and the top layer is negatively charged (N-type). The two layers form an electric field between them which only allows the electrons to flow from the P-type silicon to the N-type silicon. When the solar power cell is part of an external circuit, this will allow it to generate solar electricity when light strikes the top silicon surface.

Generating Solar Electricity

Making Solar Power Cells Practical - 
An individual solar cell will only produce about 1 or 2 watts of power. For most home uses, much more power is needed. To meet that need, solar power cells can be joined together to create a solar module or solar array. These are commonly referred to as solar panels.

Solar Systems - 
Solar Panels are then strung together to create a significant amount of energy, enough to cover up to 100% of your electrical consumption.
