This research work verified the input solar irradiance and average power output per day of a 10W polycrystalline silicon solar panel (PsSp) and a 10W gallium arsenide (GaAs) solar panel, both of dimension 350x290x25mm3, fill-factor 0.7 in the four different quarters of the year 2013. The average power output in KWh/m2 per day in four quarters of the year were compared to determine which quarte…

The degree of dependence of power delivered by a solar panel on input solar irradiance was examined with a 10watt polycrystalline silicon (Si) solar panel and a 10watt polycrystalline gallium Arsenide (GaAs) solar panel, each at a fill-factor of 0.7.The research was carried out at Ilesa city located at coordinates 7037′0″N 4043′00E / 7.616670N4.716670E, in Osun State of Nige…
