Design and installation of 2kW solar photovoltaic system for sustainable power supply at Taraba state polytechnic (Siwes unit), Nigeria

Reliable electricity supply remains a major challenge in many Nigerian tertiary institutions. 
This study presents the design, installation and performance assessment of a 2kW solar photovoltaic (PV) system implemented at the Students Industrial Work Experience Scheme (SIWES) unit of Taraba State Polytechnic, Nigeria. The objective was to provide a sustainable alternative to unreliable grid electricity and diesel generators. Load assessment, system sizing, component selection and installation procedures were carried out using standard PV design methods. The system consists of photovoltaic modules, charge controller, battery bank, inverter and protection devices. The estimated daily energy demand of the facility was approximately 6kWh. Based on local solar irradiance conditions, a 2kW PV array with battery storage was designed to meet the demand with additional reliability margin. Results from the installation demonstrate that the system is capable of meeting the office load requirements while reducing dependence on fossil fuel generators. The study demonstrates the technical feasibility of small-scale solar PV systems for institutional applications in Nigeria. The findings provide a practical framework for similar renewable energy installations in educational institutions and public facilities.
