Abstract:
The measurement of output power of silicon polycrystalline arrayduring normal and smoked days has been carried out. This array has an output tolerance about 3 %. The experiment was done for 6 days, started from 13 June until 14 June 2013 for the normal days and 24 June until 27 June 2013 for smoked days, at Department of Physics, Faculty of Mathematics and Natural Sciences, University of Riau. The result of the normal measurements show that average power output for normal days was greater than that for smoked days that was 46,6 Watt and 35,5 Watt respectively. The average output of voltage was 28,25 Volt while for smoked days, the voltage was 13,9 Volt. Higher values of the average output of voltage for normal days was due to the higher intensity of sunlight during the normal days compared to smoked days.
