According to the International Energy Agency Energy Access Outlook,2016, about 1.1 billion people worldwide, lack access to electricity and about 95% of these people are in Sub-Saharan Africa and Asia. Moreover the electricity needs of many people who have access to electricity in these regions are not met at all, because of unreliable on grid energy supplies.Access to electricity is very vital in promoting socio economic development and impacts very largely on many different economy sectors, especially in African countries. Thus new smart energy supplying solutions must be explored to combat this challenge. The aim of this project is to address the energy need by harnessing the abundant solar photo voltaic (PV) energy from the sun by developing a compact solar (PV) energy absorbing unit called the Simba Energy Box.The Simba Energy Box is a solar energy based intelligent system that consists of a solar panel, DC/AC inverter, battery and controllers. The main idea is to allow the Simba Energy Box units to be able to communicate and to do electrical energy transactions (sharing) over a blockchain architecture.
The Simba Energy Box development approach has four main layers.
Blockchain is a distributed ledger that makes it possible to create a tamper-proof digital ledger of transactions and share them.This will be implemented over the IBM Watson IoT platform.The platform allows us the developers to add selected IoT data to private blockchain ledges that can be included in shared transactions.The platform filters device events and sends only the data that is required to satisfy the contract
Various electrical parameters measuring instruments such as ammeters and voltmeters will be used to measure electrical parameters.However in the initial stages of the development of the Simba Energy Box system,a Matlab simulation program will be used to generate these parameters on each unit.Parameters such as voltage, current, angle of incidence of the sun rays, temperature and cloud cover will be simulated.
