Bibliography

This section applies to the electrical installation of PV generator intended to supply all or part of an installation and feeding of electricity into the public grid or local distribution. In this section, the electrical equipment of a PV generator, like any other item of electrical equipment, is dealt with only so far as its selection and application in the installation is concerned.The electrical installation of a PV generator starts from a PV module or a set of PV modules connected in series with their cables, provided by the PV module manufacturer, up to the user installation or the utility supply point.Requirements of this document apply to–PV generators for supply to an installation which is not connected to a system for distribution of electricity to the public,–PV generators for supply to an installation in parallel with a system for distribution of electricity to the public,–PV generators for supply to an installation as an alternative to a system for distribution of electricity to the public,–appropriate combination of the above.Requirements for PV generators with batteries or other energy storage methods are under consideration.
