Experimental Analysis Of 960 W Solar Power Plant

This work provides an outdoor annual performance evaluation of 960 Wp photovoltaic (PV) power system installed on the roof of Faculty of Mechanical Engineering and Naval Architecture, located in Zagreb, Croatia. Its main purpose is to encourage the use of solar energy based on the obtained results and benefits that it represents towards global aim of reducing greenhouse gases (GHGs) emissions. The system is consisted of 6 PV modules of 160 Wp each, rated at 12.5% efficiency under standard conditions, which are connected to 6 utility-interactive micro inverters of 215 W to convert three phase 230 V AC. Energy performances of these modules mounted in pairs on a fixed, single-axis, and dual-axis solar trackers are compared and analyzed. The experimental data were recorded from January 21st 2016 to January 21st 2017 based on real time observation. In a given period, the solar power plant produced a total of 1.241 MWh of energy with PV panel gains of 378 kWh from fixed installation, 401 kWh from single-axis solar tracker, and 462 kWh from dual-axis solar tracker. The study also analyzed data gathered from the online solar photovoltaic energy calculator, which was used to estimate the monthly irradiance and solar electricity production of a described PV system with equally defined modules tilt and orientation. Assessed yearly energy output is 1.33 MWh of which PV panels on fixed mount, single-axis solar tracker, and dual-axis solar tracker generate 412 kWh, 439 kWh, and 479 kWh electricity. Due to the comparison of estimated parameters to observed experimental results, an insight was given into the accuracy of the predicted performances of potential PV installations.
