What standards are included in a photovoltaic system?
In addition to referencing international electro-technical photovoltaic standards such as IEC 61215, IEC 61646 and IEC 61730, typical standards from the building sector are also included, such as: EN 13501 (Safety in case of fire); EN 13022 (Safety and accessibility in use); EN 12758 (Protec-tion against noise).
What are the technical specifications of solar power grid?
The technical specifications include permitted voltage and frequency variations in addition to power quality limits of harmonic distortion, phase unbalance, and flickers. Operational limits and capability requirements will be explained and discussed. Solar power grid connection codes of Egypt are explored first.
How much power can a PV array use?
Even with what appears to be a dramatic variation in voltage of 5% (for example, 543 V compared to 570 V), the PV array power, which is a mere 2% below the MPP power, can still be used. These numbers apply to conventional PV modules with crystalline Si cells; and losses are even lower with many thin-film PV cells.
What are the technical aspects of a PV power plant?
Technical areas addressed are those that largely distinguish PV power plants from smaller, more conventional installations, including ground mounted array configurations, cable routing methods, cable selection, overcurrent protection strategies, equipotential bonding over large geographical areas, and equipment considerations.
