6 FAQs about [Solar Cell Welding Strip]
What are the different types of PV welding strip?
There are two forms of PV welding strip applied to photovoltaic modules: interconnection strip or bus bar and PV bus bar. In typical silicon solar cells, both are needed. The interconnection strip is directly welded on the silicon crystal to connect the solar cells in the solar panel with each other.
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.
How a high quality PV welding strip can improve solar panels performance?
The high efficiency and durability of solar panels can only be achieved with high-quality PV welding strips properly installed in solar panels. High quality PV welding strip can also improve the production efficiency of solar panels and reduce the scrap rate.
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 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.
