A flow chart for solar panel can simplify the complex manufacturing process into clear, structured steps, helping engineers, technicians, and even ordinary users understand how raw materials are transformed into efficient, power-generating solar panels.
In our daily lives, solar panels are widely used—from rooftop photovoltaic systems and large-scale solar farms to portable solar chargers, they are revolutionizing the way we utilize energy. Understanding the manufacturing process not only helps in selecting the right solar products but also fosters greater interest in clean energy technologies.
How to Make a Flow Chart for Solar Panels Manufacturing?

Main Process of the Flow Chart for Solar Panels Manufacturing
Before making the flow chart, we need to clarify the main process of solar panel manufacturing. The following are typical manufacturing steps.
Silicon material purification: purify metallurgical grade silicon to solar grade silicon.
Silicon wafer cutting: cut silicon ingots into thin slices.
Coating and doping: form a PN junction on the surface of the silicon wafer and coat it with an anti-reflection layer.
Printing electrodes: make conductive grid lines through screen printing technology.
Cell assembly: connect the cells in series and package them.
Finished product testing: test the efficiency and weather resistance of the finished product.
These steps constitute the backbone of the flow chart. Next, we need to add detailed branch processes and technical parameters for each step.
Branch Steps of the Flow Chart for Solar Panels Manufacturing
The following are the detailed branch steps of each main process:
(1) Silicon material purification
Operation: Metallurgical grade silicon (98% purity) is purified to solar grade silicon (99.9999%) through chemical vapor deposition (CVD).
Parameter annotation: Resistivity detection (target value: 1-3 Ω·cm).
Decision point: Is the purity of the silicon ingot up to standard?
Yes → enter the cutting step;
No → return to the purification step.
(2) Silicon wafer cutting
Operation: Use a diamond wire saw to cut the silicon ingot into 180-200 micron silicon wafers.
Parameter annotation: Cutting loss rate (<5%).
(3) Coating and doping
Operation: Form a PN junction on the surface of the silicon wafer through high-temperature diffusion, and coat it with a silicon nitride anti-reflection layer (thickness 80nm).
Parameter annotation: Reflectivity (<5%).
(4) Electrode printing
Operation: Screen printing silver paste and aluminum paste, sintering to form conductive grid lines.
Parameter annotation: Grid line width (≤50μm), conductivity test (resistance <0.1Ω/sq).
(5) Cell assembly
Operation: Solder the cells in series, stack EVA film and backplane, and package them into components.
Parameter annotation: Lamination temperature (150℃), vacuum environment.
(6) Finished product testing
Operation: Conduct IV characteristic test and weather resistance test.
Parameter annotation: Open circuit voltage (Voc=30-40V), short circuit current (Isc=8-10A), fill factor (FF>75%).
Symbols and Parameter Annotations of the Flow Chart
When drawing a process flow chart, it is important to use standard symbols and clear parameter annotations:
Rectangles: indicate operation steps (such as "Silicon material purification").
Diamonds: indicate decision points (such as "Is the purity of the silicon ingot up to standard?").
Ovals: indicate the beginning and end of the process.
Arrows: indicate the flow direction of the process.
Parameter annotations: Use small fonts or footnotes to mark key parameters (such as "Resistivity: 1-3 Ω·cm").
For example:
Start (oval): "Silicon material purification process starts".
Operation (rectangle): "Metallurgical grade silicon → CVD purification to solar grade silicon".
Decision (diamond): "Is the purity of the silicon ingot up to standard?"
Yes → enter the cutting step;
No → return to the purification step.
