How to Make a Portable Solar Panel
1. Gather Essentials
– Solar cells (5-6V, monocrystalline/polycrystalline)
– Solar charge controller
– 12V battery (lithium-ion or lead-acid)
– Waterproof case/frame, wiring, solder, and protective glass/epoxy.
2. Assemble Cells
– Connect cells in series (positive to negative) for desired voltage (e.g., 2-3 cells for 12V).
– Solder securely and insulate wires to avoid shorts.
3. Build the Case
– Mount cell array and charge controller inside the case.
– Connect cells to the controller’s input, and the battery to its output.
4. Protect & Finish
– Cover cells with glass/epoxy, seal the case waterproof.
– Add USB/DC ports for device charging.
5. Test & Use
– Charge in sunlight, check voltage with a multimeter, then power devices on the go!
