Abstract

Pada tugas akhir ini telah dilakukan studi mengenai evaluasi unjuk kerja dc-dc konverter pada sistem pompa air fotovoltaik. Efisiensi panel surya dihitung dengan membandingkan output dengan daya yang masuk. Semakin banyak energi radiasi yang diubah menjadi daya, semakin besar efisien panel surya. Dengan kata lain, semakin banyak radiasi yang diubah menjadi daya, semakin efisien panel surya. Pengontrol pelacakan titik daya maksimum, juga dikenal sebagai pengontrol MPPT, digunakan untuk meningkatkan energi yang dikumpulkan dari panel surya. Pemilihan konverter yang tepat merupakan salah satu kesulitan karena berdampak pada perilaku sistem fotovoltaik. Berdasarkan data tegangan pengukuran didapatkan sebanyak 725 data memiliki nilai lebih kecil dari 176,8 volt yang berasal dari nilai tegangan keluaran optimum panel fotovoltaik. Maka dapat ditarik kesimpulan bahwa Converter yang digunakan pada pengujian ini yaitu buck Converter dikarenakan tegangan yang keluar dari fotovoltaik mengalami penurunan tegangan setelah melewati DC-DC Converter. Kemudian, didapatkan nilai efisiensi yang dihasilkan oleh dc Converter sebesar 89,12%. Dapat dikatakan bahwa efisiensi dc-dc Converter sudah berjalan dengan optimal dikarenakan nilai efisiensi sudah lebih dari 80%. Setelah itu, Berdasarkan data pembacaan software dan perhitungan pada excel didapatkan nilai efisiensi fotovoltaic water pump system atau dengan kata lain efisiensi total sebesar 17,73 %. Dengan di dapatkannya efisiensi total tersebut dapat dikatakan bahwa sistem sudah bekerja secara optimal. Dikarenakan secara umum, efisiensi total dapat mencapai sekitar 15% hingga 25%.

In this final project, a study on the evaluation of the performance of dc-dc converters in photovoltaic water pump systems has been carried out. The efficiency of a solar panel is calculated by comparing the output to the incoming power. The more radiant energy that is converted into power, the greater the efficiency of the solar panel. In other words, the more radiation converted into power, the more efficient the solar panel. Maximum power point tracking controllers, also known as MPPT controllers, are used to increase the energy collected from solar panels. Selection of the right converter is one of the difficulties as it impacts the behavior of the photovoltaic system. Based on the measurement voltage data, it is found that 725 data have a value smaller than 176.8 volts which is derived from the optimum output voltage value of the photovoltaic panel. So it can be concluded that the Converter used in this test is a buck Converter because the voltage coming out of the photovoltaic has a voltage drop after passing through the DC-DC Converter. Then, the efficiency value generated by the dc converter is 89.12%. It can be said that the efficiency of the dc-dc converter has run optimally because the efficiency value is more than 80%. After that, based on the software reading data and calculations in excel, the efficiency value of the photovoltaic water pump system or in other words the total efficiency is 17.73%. With the total efficiency obtained, it can be said that the system has worked optimally. Because in general, total efficiency can reach around 15% to 25%.
