The Manufacturing Process: From Cells to Modules

Building a DIY solar panel model involves several steps:

1. Preparing the Solar Cells:
   • Test each cell to ensure they are functioning. Handle with care as they are delicate and can break easily.
2. Soldering the Cells:
   • Solder tabbing wire onto the front and back of each cell to connect them in series. Ensure the soldering iron is properly heated and the flux pen is used to facilitate a clean connection.
3. Connecting the Cells:
   • Connect the soldered cells in series using bus wire to form a module. The number of cells connected will determine the voltage output of the model.
4. Assembling the Panel:
   • Place the connected cells on a piece of plywood or plastic sheet. Cover the cells with encapsulation material (EVA) to protect them from moisture.
5. Adding the Front Cover:
   • Place the plexiglass or glass sheet over the encapsulated cells and secure it with silicone sealant to create a weatherproof seal.
6. Framing the Panel:
   • Use an aluminum frame to secure and protect the edges of the panel.
7. Wiring and Junction Box:
   • Attach the junction box to the back of the panel, connect the bus wires, and ensure all electrical connections are secure and insulated.
