What is a photovoltaic module?

For real-world applications, photovoltaic modules are fabricated by electrically connecting typically 36 to 72 solar cells together in a so-called PV module. A PV module (or panel) is an assembly of solar cells in a sealed, weather-proof packaging and is the fundamental building block of photovoltaic (PV) systems.

How many solar cells are in a photovoltaic module?

An individual solar cell is fragile and can only generate limited output power. For real-world applications, photovoltaic modules are fabricated by electrically connecting typically 36 to 72 solar cells together in a so-called PV module.

What is the role of automation in solar panel production?

The use of advanced machinery and automation in solar panel production has not only led to an increase in efficiency but also a reduction in costs. In subsequent articles, we will go deeper into each of the main processes as well as the role of automation in solar manufacturing.

How are PV cells assembled?

Panel Assembly. PV cells are wired together on a glass sheet to form a panel, which typically has 60 or 72 cells (120 or 144 half-cut cells). The assembly is covered on the front and backside with a plastic laminate, sheet of glass, or other material for protection from the environment.

How do Atlas robots work?

This first-generation of Atlas robots are comprised of one robotic arm that picks and places the photovoltaic modules onto the solar structures and their respective clamps. Its computer vision system enables Atlas to “see” the solar structure and clamps.

How are photovoltaic absorbers made?

The manufacturing typically starts with float glass coated with a transparent conductive layer, onto which the photovoltaic absorber material is deposited in a process called close-spaced sublimation. Laser scribing is used to pattern cell strips and to form an interconnect pathway between adjacent cells.
