| Summary: | 碩士 === 國立交通大學 === 企業管理碩士學程 === 105 === In order to achieve the goal of non-nuclear homes, Taiwan government sets that the renewable energy generation accounted for up to 20%, of which solar photovoltaic capacity to 20 GW in 2025. According to the information from Taiwan Power Company (TAIPOWER), the renewable energy generation accounted for 5.1% in 2016, and the installations of solar power system is about 0.98 GW in the end of February 2017. The current situation represents the installed capacity of solar power system will continue to increase in the future. In view of the trend and achieving the goal of government sets, the power generating performance of solar power plants will be the focus for the power plants owners, government and investors. This study analyzes the performance of generating efficiency of 10 private solar power plants in northern, middle and southern Taiwan by using the historical data from online solar monitoring system. In order to evaluating the performance of solar power plants, this study employs three major indexes, performance ratio (PR), daily mean yield (DMY) and capacity utilization factor (CUF) to present the yearly and monthly performance. After using and viewing the trend of PR, DMY and CUF to evaluate and understand the trend performance during the long-term operation, the results could be the reference for government and personal future investment in solar power plants.
This study found that there are 7 power plants have lower PR, 5 of 7 start to run less than 5 years and these 5 power plants are large-scale. The PR decline by 8-17% in 5 years. In addition, the trend of yearly PR shows that the value is higher in winter (January and February) than the summer (May to August) means that the stronger sunshine does not absolutely have the greater generating performance.
Furthermore, on the September in 2015 and 2016 have poor performance of power generation, the main reason is the typhoon attack caused the system be shut down or damaged to affect the performance in September and October. Consequently, the intensity of enduring the strong wind should be considered carefully for building the solar power plants in Taiwan and must calculate the risk of natural disasters into the investment and evaluation.
