AC/DC Converter – rectifier

A device that transforms alternating current into direct current

Albedo

the albedo of an object is a measure of how strongly it reflects light from light sources as the Sun.. Synonymous with Solar Reflectance

Angle of inclination

This is the angle of the titled module measured against the horizontal.

Angle of declination (declination angle)

Is the angle between the rays of the Sun and the equator.

Ampere-hour (abbrev.: Ah)

Is a unit of electric charge which corresponds to an electric charge transferred by a steady current of one ampere for one hour

Ampere (abbrev.: A)

SI base unit of electric current, equal to the flow of one coulomb per second.

Angle of elevation (also known as solar elevation angle, elevation angle)

Is the angle between the direction of the geometric centre of the sun and the horizon.

Angle of incidence

This is the angle between the perpendicular line to a titled surface and the sun ray. 

APCVD ( Atmospheric Pressure Chemical Vapour Deposition)

Is a chemical process at atmospheric pressure which is used to deposit the anti-glare layer on PV cells. .

Array

An assembly of PV modules electrically connected together.

Azimuth angle

The angular distance measured clockwise  in degrees around the observer’s horizon starting  from South (0°South; 90° West; - 90°East)

Amorphous silicon

Is a  non-crystalline  form of silicon and used for manufacturing PV cells.

AC voltage

Is the voltage between two points in a circuit which varies in time as a sine wave.  AC voltage is used in electrical distribution networks, household and industrial appliances and utilities
