WHAT IS A SOLAR ELECTRIC OR PHOTOVOLTAIC SYSTEM?
Photovoltaic(PV) systems begin with PV cells that are connected electrically in series and/or parallel circuits. The PV cell is small and typically produces about 1 or 2 watts of power. The circuits are then sealed in an environmentally protective laminate to form modules. The modules are assembled as pre-wired, field installable units into the photovoltaic panels. The panels will contain one or more PV modules. The end construction is a photovoltaic array consisting of any number of PV modules and panels that can meet almost any electric power need.
