6 FAQs about [Photovoltaic panel welding temperature requirements]

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 the initial temperature of a welding strip?

The initial temperature of the model is set as 50°C, because the other side of the welding strip directly contacts with 380°C electric iron, the temperature of this side is 380°C. Because the solder must be melted during welding, the temperature of the part contacting the silicon wafer is set at 240°C.

How to declare a photovoltaic cell ready?

The humidity should not go beyond 65% per day and temperature should not exceed 25±5. Before you declare your photovoltaic cell ready, you need to carry out a mirror surface inspection. This step will help give you an assurance that the mirror of the solar panel is in a perfect condition.

Does heterogeneous welding strip affect PV Assembly power improvement?

The welding strip is an important part of photovoltaic module. The current of the cell is collected by welding on the main grid of the cell. Therefore, this paper mainly studies the influence of different surface structure of heterogeneous welding strip on PV assembly power improvement. The main findings are as follows:

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 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.
