DESIGN AND CONSTRUCTION OF 1 KW PORTABLE SOLAR POWER SYSTEM
Abstract
This project presents the design, construction, and testing of a 1kW portable
solar power system capable of providing reliable electricity for small-scale
household, office, and field applications. The study is motivated by the
challenges of unstable grid supply and the increasing demand for renewable
energy solutions in Nigeria and beyond. The system consists of a photovoltaic
array, charge controller, deep-cycle battery storage, and a pure sine wave
inverter, all integrated into a portable framework for ease of transport and
installation. Using solar irradiation data, load analysis, and system sizing
calculations, the system was designed to provide continuous power for
appliances such as lighting, fans, laptops, and communication devices.
Experimental results show that the system achieved an average efficiency of
85%, with stable voltage output and satisfactory load performance. The
findings highlight the viability of solar energy as a sustainable and
environmentally friendly alternative to fossil-fuel generators, particularly
in remote and off-grid areas.
