6 FAQs about [What is the material of the low temperature welding belt of photovoltaic panels ]
What is photovoltaic welding strip?
The so-called photovoltaic welding strip is to coat binary or ternary low-melting alloy on the surface of copper strip with given specification. The methods of continuously and evenly coating low-melting metals and alloys on the metal strip include electroplating, vacuum deposition, spraying and hot-dip coating.
How welding strip affect the power of photovoltaic module?
The quality of welding strip will directly affect the current collection efficiency of photovoltaic module, so it has a great impact on the power of photovoltaic module. The so-called photovoltaic welding strip is to coat binary or ternary low-melting alloy on the surface of copper strip with given specification.
What are the physical properties of solar cell welding materials?

How to string Weld a solar panel?
4.3.1 String Welding Procedures during Solar Panel Production Follow these procedures when string welding a solar panel: Check for the defects on the cell. These include improper angle, lack of edge, and the poor state of the welding belt. Put the solar panel cell into the material box and start to circulate.
How to reduce the shading area of a photovoltaic welding strip?
The shading area of the photovoltaic welding strip is reduced by reducing the width of the main grid line and the PV welding strip, and the total amount of light received by the solar cell is increased. However, the contact resistance of the whole PV assembly is too large, which increases the electrical loss of the photovoltaic module.
