Projection for PV sizing for a stand-alone "all-direct current" telecommunication system using the mismatch factor algorithms

Abstract

Solar PV energy has been widely used for decade especially where connection to a national grid is seldom possible and other sources such as fossil fuel and others are either unavailable or uneconomical. Solar PV energy owing to its free, natural availability and environmental friendliness has found demand for use in industries, homes and institutions. However, very little research has been carried out to precisely establish its effectiveness, reliability and adequacy. III this research work, an investigation was carried out for three months ill the year 2012. The three months were June, July and August. Voltage. current and hence the power data 1\ ere measured daily using 3 data logger at the interfaces I, 2 and 3 shown III figure I. The irradiance data were also measured using a pyrometer for the same duration of time as that of voltage and current the irradiance data collected and power harnessed by the installed PV system varied from month to month with July recording the lowest and August the highest. Projection for PV sizing WJS carried out us.ng the mismatch factor Algorithms
