摘要:The data logger was developed to evaluate potential area of solar panel. Current sensor and voltage sensor were integrated on data logger board to measure parameter that affected toward efficiency of PV system. The obtained Calculation power will be used for assessment and evaluation during collecting data. But, Maximum Power Point Tracking (MPPT) method will provide an efficient data of peak power. The benefit of using data logger is the ability to automatically collecting data on several period. The data can be plotted into V-I graph and P-V graph for analysis. The test bench result was recorded that the maximum power reaches 35W. This data logger with MPPT method can be used as portable recorder to compare the power in different area.
