5. 3 Operation, Performance and Maintenance of PV Systems
Summary / Abstract:
Solar PV systems installed worldwide has grown exponentially for the energy production. However, the performance of PV systems is strongly affected by various factors. PV system design and weather condition are major among factors effecting on the overall performance of solar PV systems. In the case of large scale photovoltaic power plants, various parameters are used for selecting optimal design and geographical location. The evaluation of these impact parameters is therefore worth exploring when designing future solar projects to achieve the most realistic results possible. The main objective of this research is to assessment of the sensitivity of various factors on the performance of large scale power plants. The PV system considered in the present study, Ten Merina, was installed in the region of Thies (Senegal). NREL System Advisor Model (SAM) model is used to investigate the effect of the relevant parameters that could significantly affect performance PV systems. The preliminary results show the validation of System Advisor Model (SAM) with the experimental data to an existing large-scale photovoltaic power plant. POA irradiance simulated is be considered close enough to POA irradiance measured to be deemed its practical equivalent. Monthly energy production and performance parameters are as well be considered close to the data experimental. So, it is possible to use different design and various weather condition to quantify their impact on the performance of large scale PV power plant.
