Abstract
The dynamics of insolation condition have an effect on the performance and energy output of photovoltaic (PV) systems. Therefore, it is sensible to monitor the output performance of a PV system on the sub-module level under real-time insolation conditions. However, measurements of the PV module so far are often conducted either under standard test conditions (STC) where insolation lacks diversity, or at a power grid level where the characteristics of individual modules are ignored. To compensate for the shortage of data in the area of sub-module measuring under real-time condition, a method of field measurement setup was developed. The method involves automated control of measurement instruments as well as automated data acquisition and manipulation. From examination of the interaction between measurement instruments and operating systems, a general-purpose control circuit and program were developed for field measurement. Measurement results were then analyzed with possible insolation variations, and certain output patterns under similar insolation conditions were compared and categorized for future application. The research and programming done within the scope of this project will facilitate an effective performance evaluation of various PV modules under realistic conditions.
