One-Year Evaluation of a 20 MW Photovoltaic Power Station

Abstract:

Grid-connected PV power station is one of the most important applications of photovoltaic system, generating low cost and high-quality electric power without non-renewable energy, as well as relaxing the tightness of daytime power demand. In China, it is usually installed on remote open area for low cost to guarantee the abundant solar power. However, this kind of place usually comes with tough weather conditions. In this paper, the property of the PV test field is estimated by its output characteristic. One inevitable and two avoidable reasons which affect the plant output are proposed. Firstly, the inevitable factor is weather, and the assessment analyzing the performance of PV power system under different weather conditions, such as sunny, cloudy, rainy and snowy is then presented. Secondly, losses owing to the mounting type and partial shading, which can be reduced by well designing and installing, are also mentioned and analyzed.
