Rancang Bangun Sistem Data Logger Berbasis Visual Pada Solar Cell

Abstract ? This system developed to measurement optimizing the output of solar cell panel which using wireless systems to made a visual data logger on the solar cell which is a system to facilitate the measurement, reading, and communicating data in reading the electrical energy released in the solar cell. The design of this system has two sub-systems, the first sub-system is the design of hardware in the form of electronic device design data logger system equipped with SD card as back up data, then current sensors and voltage sensors as readers of electrical energy output in solar cell. The second sub-system is the design of software on the data logger and software design in visual basic as reading data delivery. The data reader of this system show the ampere values difference in 2.6%, while the percentage difference in voltage values was 0.33 with standardization of IEC (International Electrotechnical Commission) 3.2% ampere meter and volt meter 2, 5%. The system also saves the measurement results in the database and SD card data logger automatically every 15 minutes which interval in 1 minute to reading the data and the results of stored reads are date data, current values, voltage and power values.
