6 FAQs about [Photovoltaic bracket design safety factor]

Are photovoltaic systems safe?

Photovoltaic systems have played a key role over the last decade in the evolution of the electricity sector. In terms of safety design, it’s important to consider that a PV plant constitutes a special system of generation, where the Direct Current (DC) presence results in changes to the technical rules.

What are the standards for safe design of a PV system?

The specification for the safe design of a PV system is currently defined by International Standards: NEC 2011 and UL1741 for the countries of North America , ; IEC 60364-7 and IEC 62257-7 for the countries of the European Community , .

Do electrical phenomena in PV systems affect fire risk?

Choices regarding the grounding of the generator and its protection devices are fundamental for a design that evaluates fire risk. The subject of the article is the analysis of the relation between electrical phenomena in PV systems and the fire risk related to ensuring appropriate fault detection by the electrical protection system.

What are the installation requirements for a PV array?

Installation requirements are also critically dependent on compliance with the IEC 60364 series (see Clause 4). PV arrays of less than 100 W and less than 35 V DC open circuit voltage at STC are not covered by this document. PV arrays in grid connected systems connected to medium or high voltage systems are not covered in this document.

How safe is a PV plant?

Concerning the design of safety, it’s particularly important to take into account that a PV plant constitutes a special system of generation in which the presence of Direct Current (DC) results in changes in the application of general technical rules, and the system itself is a possible source of fire should certain electrical faults occur.

Why is a PV plant a fire hazard?

A PV plant is a special generation system in which the presence of DC results in changes to the application of general technical rules. Moreover, if certain electrical faults occur, the system itself can become a possible source of fire.
