Materials Required: 1. A Cap 2. Wires( take the ones which match your cap color) 3. Soldering Iron 4. Solder 5. Tape 6. A Mobile Charger 7. Mobile 8. Light 9. And yeah, Solar Panels
NOTE: My charger gives an output of 6V and 300mA, so I've chosen my Solar Panels accordingly. Where each panel's Voltage output is 3V and 300mA. So when I connect my two panels in series, the voltage is added while the current remains untouched. Hence they produce 6V(3V+3V) and 300mA.
