6 FAQs about [Schematic diagram of automatic string welding of photovoltaic panels]

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.

What is a solar schematic diagram?

The schematic diagram typically starts with the solar panels, which are the main source of the system’s power. The panels convert sunlight into electricity through the use of photovoltaic cells. The diagram shows how the panels are connected in series or parallel to form an array, allowing for maximum energy production.

How does a photovoltaic module manufacturing line work?

The first phase in a photovoltaic module manufacturing line is joining the solar cells, which is done by a solar tabber and stringer, a totally automatic machine able to optimise the very delicate phase of stringing and tabbing.

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.

How solar simulator affect the size of photovoltaic welding strip?

According to IEC61215 standard, the light emitted by solar simulator is vertically incident on the surface of photovoltaic welding strip through glass and EVA. The change of surface structure of photovoltaic welding strip will change the reflection path of light on the surface of photovoltaic welding strip, affecting the size of α 1 in Fig. 1.

What are the physical properties of solar cell welding materials?

The thickness of silicon wafer is 160 μm, the thickness of PV copper strip is 0.1 mm, the thickness of Sn alloy coating is 15 μm and 25 μm respectively. The physical properties of materials used in solar cell welding are shown in Table 6.
