Grid connected solar photovoltaic system efficiency : case study for landed residential

Abstract

The purpose of this study is to evaluate the field test efficiency of grid connected solar PV system by simulation, field test results and real time data monitoring. The real behavior of modules by respect to the specifications was one of the greater uncertainties in the PV system performance evaluation. The reason is the mismatch of poor cell by the manufacturer during fabrication. The thesis demonstrates the performance analysis of solar module by using solar module analyzer, irradiance meter and inclinometer under different irradiation at site. The peak power produced is measured and compared with the manufacturing test report to ensure all the modules in the string will have power rating at the acceptable tolerance. The real time monitoring is implemented by using Solar-Log in order to obtain the absolute maximum performance from the solar energy system at all time. The real time data is recorded and compare with the PVSYST simulation results. Results obtained were compared to validate the efficiency of PV system. Finally, economic analysis of PV system is presented by using simple payback method to determine the return on investment (ROI).At the end of study, recommendation and suggested solution will be presented to increase the reliable and efficiency of photovoltaic (PV) system. By increasing the efficiency of PV system, more energy will be generated which contribute to a better return of investment (ROI). Hence, the renewable energy will becomes a viable and sound long term investment for companies, industries and also for individuals.
