Aptech Africa recently designed, supplied, installed and commissioned two off-grid solar systems at two World Food Program (WFP) offices in Sierra Leone.
Both of these systems consisted of a Victron 5KVA inverter, a roof-mounted 3.96kWp of solar PV with 9.6kWh of 200Ah of Soleil Power lead acid battery storage and Victron Charge controller of 100A with Maximum Power Point Tracking. High quality products of modern technology systems with online monitoring device provisions that communicate the status of the batteries, inventor and charge controllers which are key components of the system were carefully selected to increase efficiency of the system.
The WFP offices are located in Gbangbatoke in Moyamba district, and Portoru in Pujehun district with the focus of reducing carbon emissions and reducing power interruptions during working hours.
The location has no stable supply of electricity and, as WFP is an international humanitarian organization, interrupted power supply is a big challenge towards achieving their global goal of proving aid to the people, thus chose to opt to solar energy which guarantees power supply, eliminating power interruption for critical IT equipment, ensuring smooth running of daily office works and data storage for the organization resulting in no delays in reaching out to every man and woman in need.
With this installation, the WFP is also moving towards the global Sustainable Development Goals (SDG 7) achievement of affordable and clean energy that ensures development for present and future generations.
