Dial-a-Photon: Cell phone and small solar panel buy African power

Start with $10 upfront and $1 per week = $58 first year, $48 second year

Users spend nothing up front for the hardware except for a deposit of around $10. They buy a scratch card for $1.00 per week from a local store, send the card’s number via text, and in return receive a code via text that they enter on a keypad mounted on the system’s battery. The code works only on that user’s system.
