In this paper, an effort has been complete to inspect the performance calculation of a standalone solar photovoltaic (PV) array scheme based on electrical energy production and power conversion productivity. Shortened exact expressions for calculating performance catalogues using experimental measurements for complete PV system and its individual constituent sub modules on day, month and year basis have also been established. Investigates have been approved out on two components 40 WP and 10 WP standalone PV array and module scheme for weather condition of Salem (latitude: 11 390 N, longitude: 78 120 E and an altitude of 270 m above mean sea level). Specific performances of both constituent array and sub module were appraised and its consequence on the real performance of complete PV scheme has been offered. Mathematical calculation was approved out for a typical day in the month of 12th March 2014. It was observed from experimental results that day power transformation average and maximum efficiency of complete PV array were 62.48 % and 96.75 % correspondingly. For additional real performance calculation of PV array/module, on field investigational performance consequences have been associated with the rated (max.) results assessed at STC and also with the supreme performance results assessed for real weather conditions as gotten during research.
