Automatic assembly method of photovoltaic panels

How a photovoltaic module is assembled?

The assembly of photovoltaic modules consists of a series of consecutive operations that can be performed by automatic machines dedicated to optimizing the single production phases that transform the various raw material in a finished product.

How do photovoltaic panels work?

The creation of photovoltaic panels centers around turning crystalline silicon into solar cells. These cells are part of large solar projects worldwide. Learning about the solar cell manufacturing process shows how we’ve advanced from the first commercial solar panel to today’s advanced modules. These modules power our homes and cities.

How are solar panels made?

Sealed into ethylene vinyl acetate, they are put into a frame that is sealed with silicon glue and covered with a mylar back on the backside and a glass plate on the front side. This is the so-called lamination process and is an important step in the solar panel manufacturing process.

How to install a photovoltaic module?

The process is done by attaching the box with a suitable silicone or glue on the back sheet of the module and by making the electrical connection between the bus ribbon prepared before the lamination and the cables of the junction box. At the inside of the box, you can find by-pass diodes that protect the photovoltaic module when operating.

Why should you learn photovoltaic module production process?

By understanding the photovoltaic module production process and to learn which machines are involved in the production of a module, gives you the knowledge to understand the points that are delicate and fundamental for the production helping you in the choice of a reliable and high-quality product.

How a photovoltaic cell can be integrated into a production line?

Some of this equipment can be integrated into the production line according to the wished level of automation. The photovoltaic cells are placed in a piece of equipment, called solar stringer, that interconnects the cells in a series by soldering a coated copper wire, called ribbon, on the bus bar of the cell.
