Modified Angstrom Solar Radiation Model for Abeokuta Nigeria

Abstract

Sustainable power supply still remains the challenge in developing countries. Unfortunately the growing energy need is directly proportional to the population growth. Hence, there is the need to step-up on the alternative energy use. The adoption of solar technology in the research site is encouraging-partly because of the low cost of purchasing solar devices. However, there is the issue of short lifespan of the photovoltaic (PV) panel that operates in the area. This research used the modified Angstrom solar radiation model to determine that the main cause of short PV lifespan is solar spectrum signature over the research area. It is recommended that solar companies should start incorporating spectra filtering layer to protect the PV panel.
