Abstract
Solar tracker merupakan gabungan sistem mekanis yang dapat menggerakkan suatu sistem panel surya agar selalu mengikuti arah matahari. Sistem solar tracker ini diharapkan dapat mengoptimalkan daya keluaran dari photovoltaic. Berdasarkan penelitian-penelitian yang telah ada sistem solar tracking banyak dikembangan dengan kondisi fix based, sehingga pada penelitian kali ini akan dikembangkan sistem solar tracking menggunakan metode mobile tracking. Mobile solar tracker mempunyai dua tipe yaitu aktif dan pasif. Pada tipe aktif menggunakan sensor photodioda (LDR), sedangkan tipe pasif menggunakan posisi matahari sehingga dapat digunakan pada saat kondisi matahari tidak cerah. Penelitian ini menerapkan logika Fuzzy yang berbasis auto tuning dan digunakan untuk menala nilai Kp dan Ki yang akan digunakan dalam sistem sehingga dapat meningkatkan kinerja sistem solar tracker. Hasil pengujian menunjukkan bahwasannya sistem kontrol dapat diterapkan, dengan menggunakan 3 dan 5 jumlah keanggotaan didapatkan respon yang terbaik ketika menggunakan 5 jumlah keanggotan dengan parameter indeks performansi yang didapatkan pada salah satu sudut pitch (300) didapatkan nilai rise time (tr) 0.61 detik, settling time (ts) 5.18 detik, maximum overshoot 3.18% dan error steady state (ess) 0.45%. Peningkatan efisiensi energi yang dihasilkan oleh mobile tracking sebesar 52.37%.
===========================================================================
Solar tracker is a combination of a mechanical system that can move a solar panel system to always follow the direction of the sun. The solar tracker system is expected to optimize the output power of photovoltaic. Based on existing studies, solar tracking system has been developed with fix-based condition, so in this research will be developed solar tracking system using mobile tracking method. Mobile solar tracker has two types: active and passive. In the active type using a photodiode sensor (LDR), while the passive type uses the position of the sun so it can be used when the sun is not bright conditions. This research applies Fuzzy logic based on auto tuning and used to tune the value of Kp and Ki which will be used in the system so as to improve the performance of solar tracker system. The result of the test shows that the control system can be applied, using 3 and 5 the number of members get the best response when using 5 membership numbers with the performance index parameters obtained at one of the pitch angles 300 obtained the time rise (tr) 0.61 sec, settling time (ts) 5.18 seconds, maximum overshoot 3.18% and steady state error (ess) 0.45%. Increased energy efficiency generated by mobile tracking is 52.37%.
