Standards from this category regulate solar cells (modules) characteristic measurement, solar cells (modules) tests and other standards referring to solar cells (modules) production and testing - production procedure, mechanic or electric photovoltaic module testing, I-U module characteristics measurement etc.
Standards available for the energy rating of PV modules in different climatic conditions, but degradation rate and operational lifetime need additional scientific and standardisation work (no specific standard at present). Standard available to define an overall efficiency according to a weighted combination of efficiencies.
A photovoltaic module is a framed or unframed assembly of solar PV cells designed to generate DC power. A photovoltaic module consists of: • the framing material (where applicable). The scope shall correspond to photovoltaic modules produced for use in PV systems for electricity generation.
At least three regulatory levels for the production, installation, operation and end of life of photovoltaic systems can be considered. Additionally, the Life Cycle Assessment methodology is also regulated by standards. In this chapter, the three levels are presented.
First, to regulate system design and battery function: IEC 62124 for stand-alone PV system design recommendations and PV performance evaluation (including battery testing and recovery after periods of low state-of-charge) in a variety of climatic conditions, and IEC 62509 for battery charge controllers.
There are currently 169 published IEC standards by TC-82 related to photovoltaic technology, and work is in progress for 69 more (new ones or revisions). This set of standards is the most broadly used by the scientific community and technicians in research centres and companies.

A solar cell, also known as a photovoltaic cell (PV cell), is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect. [1] It is a form of photoelectric cell, a device whose electrical characteristics (such as current, voltage, or resistance) vary when it is exposed to light.. Individual solar cell devices are often the electrical ...
