The Fundamentals of Electricity

Electric charge (conventionally denoted Q) is a property of matter that describes the force experienced (and exerted) in the presence of other electrically charged matter.

The Fundamentals of Energy

Most fundamentally, energy is the ability of an object or a system to perform work, and we most often observe energy indirectly by the work that is performed. The motion of an object through space, the heating of a substance and the illumination of a room are all examples of work being done and represent different forms of energy. 

Wiring Photovoltaics and the Photovoltaic Array

A photovoltaic ("PV") array describes the part of a PV system that converts solar energy into electrical energy. While there are other critically important components of the complete photovoltaic system - most significantly the inverter in all grid-connected systems - the array comprises all of the electrically-connected photovoltaic material.
