INSTALLATION OF A PV BASED SCALABLE 1.5KVA SOLAR SYSTEM FOR AN ACADEMIC OFFICE

Abstract: Solar energy represents an excellent alternative energy source due to its abundance, renewability, environmental benefits, and sustainability. In this study, a mono-crystalline photovoltaic (PV) panel system was installed to serve as an alternative power supply for the Head of the Physics Department Office. The installation involved several components, including four (4) 150W TMLG mono-crystalline solar panel, a mounting frame, 100Ah rechargeable battery, PWM solar charge controller, pure sine wave Mopower inverter, and a wiring system. Each part of the PV system was thoroughly tested for functionality before the system was fully deployed to meet the office's energy requirements. During operational hours, various office appliances such as a standing fan (40W), an energy-efficient light bulb (10W), an HP printer (220W), and a Hisense refrigerator (80W) were alternatively powered. Due to the high startup currents of appliances like the printer and refrigerator, care was taken to manage simultaneous usage to avoid overloading the system. Continuous load devices such as the fan, LED bulb, and laptop imposed a steady but manageable demand on the system over time. The system provided reliable electricity for up to 5-7 hours of continuous operation on sunny days, with peak performance observed between 11:00 AM and 3:00 PM. Power availability reduced significantly in early mornings and late afternoons due to lower solar irradiance. This illustrates that solar power systems can effectively generate sufficient electricity to run office equipment in Nigeria, contributing positively to the country's ongoing power challenges.
