Solar panel machines are the most important component in solar energy panel manufacturing.
This article is the first in a five-part series of articles, where we will give you an overview of the equipment used to produce a high-quality solar module. So, let’s dive in and unlock the secrets of solar module production!
Overview Of Machinery And Processes
Solar modules are assembled using solar panel machines and processes that include:
- Stringers
- Layup stations
- Bussing stations
- Laminators
- Foil cutters
- Foil placing stations
- Trimming and taping stations
- J-box stations
- Framers
- High potential tests
- Sun simulators
- Sorting and packing
Each of these pieces of equipment plays an important role and in the following sections, we briefly summarize how each piece of equipment or parts fits in the production of PV modules.
Stringer
A solar module or solar panel as it is more commonly known as is a group of solar cells wired together on a solar panel. A solar cell is the smallest unit of a solar module panel.
The solar stringer is for connecting individual solar cells together in a series to form a solar module. This is done by soldering the cells together.
Layup station
The layup station lays out the cells in the correct order and orientation. This is an important step as it ensures the cells are in the correct position for the bussing station and laminator.
Bussing Station
The bussing station is for connecting the cells together in a parallel configuration. This is done using a thin copper wire that is soldered onto the cells. Done correctly this process ensures the cells produce the required amount of power.
Laminator
The laminator is for laminating the cells together to form a single solar module. It uses a heated roller to press the cells together, ensuring that they are firmly connected. This process is important as it ensures that the cells will remain firmly connected, even in extreme weather conditions.
Foil Cutter And Foil Placing Station
The foil cutter and foil placing station are responsible for cutting the backsheet and placing the foil on the cells. The backsheet is a thin sheet of plastic that is placed on the back of the solar module to protect it from the elements.
The foil cutter is responsible for cutting the backsheet to the correct size and shape. The foil placing station is responsible for placing the foil on the cells, ensuring that it is correctly aligned and connected.
Trimming And Taping Station
The trimming and taping station is responsible for trimming the edges of the solar module and taping it together. This process is important as it ensures that the module will be able to withstand high winds and other environmental conditions. The tape used is a special type of tape that is designed to hold the solar module together, even in extreme conditions.
J-Box Station And Framer
The J-Box station and framers are responsible for connecting the solar module to the J-Box and installing the frame. The J-Box is a junction box that contains the electrical components that connect the module to other modules or to other components of the solar machine.
The framers are responsible for installing the frame, which is necessary for mounting the solar module.
The High Potential Test And Sun Simulator
Testing is an important step in solar module production. Solar modules have to meet certain standards and be able to perform as expected in real-world conditions.
The high potential test and sun simulator are responsible for testing the quality of the solar module. The high potential test measures the voltage of the module, while the sun simulator simulates the effects of sunlight on the module.
Sorting And Packing
The final step in producing solar modules is sorting and packing. This involves sorting the modules into different categories, such as wattage, voltage, and size. It also involves packing the modules into boxes for storage or shipping.
History Of Solar Panel Machines
The history of solar module production machines dates back to the 1970s. The solar panel machines were developed to automate the production of solar cells and modules, reducing the need for manual labor. The first machines were simple and had limited capabilities. They were mainly used for cutting and shaping solar cells. In the 1980s, the machines became more advanced, and manufacturers started to use them to produce complete solar modules.
Recent Developments In Machine Design
Developments in solar module production machines have been driven by the need for higher efficiency and lower costs. One of the most significant developments is the use of automated production lines. These lines consist of several machines working together to produce solar panels from start to finish.
The use of robots and artificial intelligence in solar panel production is also on the rise and will play a big role in further reducing costs and improving efficiency for manufacturers.
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. Make sure to check our blog so you do not miss those articles!
