Log and research for final project

Week 1 : Preliminary concept sketch

Problem : Mobile street vending is widespread globally, yet many lack reliable (and safe) access to affordable electricity especially during evening and night-time trading hours

Solution : Plug and play, pay-as-you-go solar PV system for essential lighting and load appliances of the street vendors

Main features :

  • Solar panel with built-in axis tracker for optimal energy capture in the morning before use during night-time trading hours
  • Smart controller that enables flexible installment payments (pay-as-you-go) without upfront cost and embedded security features

Research :

  • Specify load appliances, solar panel and battery sizing
  • Dual or single axis tracker
  • Dig deeper into the pay-as-you-go software and hardware https://github.com/EnAccess/OpenPAYGO-python

Week 2 : Visit to Seeed studio
