Photovoltaic Stand-Alone System

An autonomous or hybrid photovoltaic system not connected to a grid. The system may or may not have storage but most have require a battery. Photovoltaic Stand-Alone System

Photovoltaic Module

The smallest environmentally protected, essentially planar assembly of solar cells and ancillary parts, such as interconnections, terminals and protective devices such as diodes intended to generate dc power under unconcentrated sunlight. The structural Photovoltaic Module

Phase Angle Transducer

A transducer used for the measurement of the phase angle between two a.c. electrical quantities having the same frequency.

Photovoltaic Array

An interconnected system of photovoltaic modules that function as a single electricity producing unit. The modules are assembled in a discrete structure, with common mechanical support or mounting. In small systems, an array can consist of a single modu Photovoltaic Array
