Description
Solar Cable (DC Solar / Photovoltaic) – IS 17293 Marked
Application & Standards
Flexible single core Solar cables, popularly known as DC Solar or Photovoltaic cables, are used for interconnection between various elements in photovoltaic (PV) systems, including roof top PV systems in residential or commercial buildings, PV panels / module interconnection, between panel and string box, or from string box to inverter.
These are used as free hanging, movable or fixed installations in various indoor, outdoor, hazard explosion areas, in industries as well as in agriculture. They are suitable for applications in equipment with protective insulations (protecting class II).
Statutory Requirement
The Quality Control Order (QCO) on DC Solar Cable released by Ministry of Commerce & Industry on 24th August 2023, mandates the use of DC Solar cable marked with IS 17293 in India. Any person who contravenes the provisions of this Order shall be punishable under the provisions of the Bureau of Indian Standards Act, 2016.
