Abstract:
The government has launched several polices to support PV Power Plants which leads to the improvement of the PV Power Plants. Most PV power plants are selling the electricity to the PEAs grid. Therefore, the performance analysis and evaluation of energy losses in PV power plants are also required. Typically, the computer programs are used to improve the efficiency of the analysis.
The objectives of this thesis are to analyze and to evaluate energy losses of a 2 MW on-ground PV power plant, which the power was delivered to the grid between 06.30 AM and 18.30 PM. The evaluation results of the PV Power Plants were compared with the simulation software PV System Design program in order to evaluate the losses of various parts in the system. The evaluation losses were calculated as a percentage to simply estimate the improvement of the losses of PV power plant.
From the evaluation of the losses and analysis of the efficiency of the PV power plant, the efficiency was about 72.17%. The loss was mainly due to the high temperature of the PV panel which was a major factor affecting the efficiency of PV power plant. Due to the heat, the PV panel efficiency decreased as well as the equipment of PV power plant. In addition, when the results of the analysis were compared with the simulation results, it was found that the efficiency of the simulation was lower than PV power plants by 6.62%.
