ABSTRACT
In this work, βThe modeling of solar energy for the sizing of a photovoltaic moduleβ, was carried out. The aim is to create a mathematical model that estimates the harvestable incident energy per unit area at any geographical location in Nigeria at any time of the year, which is useful in sizing PV modules for a specified load. The algorithm that computes the sizing of PV modules is also incorporated in the mathematical model. The mathematical model created contains several algorithms. One of the algorithms estimates the harvestable incident daily energy, while another algorithm, uses this result to calculate the minimum size of solar panel (monocrystalline) that will trap enough power for a given load at any time of the year. Taking Electrical/Electronic Engineering department University of Benin of latitude 6.3931Β°N as our case study, the estimated incident energy was gotten to be 3.4171kwh/ππ /day. The department which consist of about 30 offices with total estimated load of 689.064KWH, a solar panel (20% efficiency, 250W, 1.25π2 monocrystalline solar panel) of total cross sectional area of 1008.3ππ was estimated to power up the total given load. Thus, the total number of monocrystalline panel to be used will be 807 panels.
