Standard EN 50618 specifies that in the design of a solar photovoltaic installation, the conductor must be made of flexible copper (class 5) tinned coated by EN 60228 Standard.
What is solar cell tabbing & tinned copper flat wire?
Solar Cell Tabbing or Interconnect Wire and Tinned Copper Flat Wire for Solar Cell Modules are primarily produced from a tin or tin alloy coated copper flat wire*. Ulbrich has been producing conductive materials for the photovoltaic industry since 1992, accumulating years of expertise that is applied to each and every order.
Solar cables must withstand these conditions, so additional protection allows for better preservation and more efficient cable performance. The tin layer that coats the copper protects it from external factors affecting its performance. In addition, tinned copper wire is easier to solder.

What is a solar cable made of?
An electrical cable's conductor can be made of copper or aluminium. Copper has 60% more electrical conductivity than aluminium, which is essential to consider when choosing a solar cable. The tinned copper coating allows compliance with European standards for solar installation.
Standard EN 50618 specifies that in the design of a solar photovoltaic installation, the conductor must be made of flexible copper (class 5) tinned coated by EN 60228 Standard. Therefore, for the solar installation to comply with EN 50618, the use of a cable with a flexible aluminium conductor for connecting solar panels is ruled out.
What are the advantages of tinned electrolytic copper conductor?
The main advantages of the tinned electrolytic copper conductor: The copper conductor offers higher tensile strength and does not require large conduit systems. Using a solar cable with a copper conductor ensures greater resistance to corrosion. With a copper conductor we obtain a more robust installation.
