Often used interchangeably with Photovoltaic Module. Especially in one-module systems , but more accurately used to refer to a physically connected collection of modules (i.e., a laminate string of modules used to achieve a required voltage and current). Photovoltaic Panel
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
The ratio of electric power produced by a cell at any instant to the power of the sunlight striking the photovoltaic cell. This is typically 9% to 14% for commercially available cells. Photovoltaic Efficiency
The ratio of electric energy produced by a photovoltaic device to the energy from sunlight incident unpn the cell. Photovoltaic Conversion Efficiency
A Photovoltaic module that uses optical elements to increase the amount of sunlight incident on a Photovoltaic cell. Concentrating arrays must track the sun. Efficiency is increased, but lifespan is decreased because of the high heat. Photovoltaic Concentrator
