Implementation of Standard Solar PV Projects in Nigeria

Abstract

The basic operating principle of Photovoltaic device is the conversion of solar irradiation into electricity. There are several applications of this principle. In Nigeria, most solar PV projects are designed for street lighting, water pumping and general stand-alone/minigrid rural electrifications. However, several solar PV projects being installed in various parts of this country fail to meet the minimum life-span due to a number of limiting factors. These include poor or improper fundamental design, use of sub-standard components, adoption of poor installation procedure by inexperienced personnel, bad construction/civil works among other factors. This has become a problem in the country and many are beginning to feel disgusted with solar PV projects as the heavy investments in such projects do not seem to be commensurate with their performances and satisfactions derivable. This paper therefore presents an overview of the performances of solar PV projects and a concise procedural approach to the implementation of standard solar PV projects in the country. In-depth analysis of performances of existing systems was also considered and the limiting factors identified with specific recommendations for improvement. We believe that if power projects are designed and executed properly by experienced technical experts, using the appropriate components and best technical procedures, standard PV projects with maximum performance output could be achieved.
