Abstract

At this time our need for electrical energy is increasing, so we need alternative new energy sources, one of which is by utilizing solar energy by using solar panels that can convert sunlight into electrical energy. But solar panels that are often used today are still less efficient because solar panels are usually installed statically (not following the movement of the sun). So in this study, the authors designed a solar tracker tool that is useful for increasing the efficiency of the voltage generated by solar panels. By using LDR sensors and servo motors so that they can make the solar panels follow the direction of the sun's rays. In this final project, a prototype solar tracking device is produced that can be monitored with Thingspeak to measure the difference in voltage produced by static solar panels and solar panels with a tracking system (dynamic). By comparing the measurement of voltage and current on a Solar Tracker made with static solar panels, it was found that the results were able to produce more power efficiency on the Solar Tracker by 19.49% compared to static solar panels. Keywords: Solar panels, solar energy, LDR sensor, servo Pada saat ini kebutuhan kita akan energi listrik semakin meningkat, sehingga diperlukan alternatif sumber energi baru, salah satunya adalah dengan memanfaatkan energi matahari dengan menggunakan panel surya yang dapat mengubah cahaya matahari menjadi energi listrik. Tapi panel surya yang sering digunakan saat ini masih kurang efisien karena panel surya biasanya dipasang secara statis (tidak mengikuti pergerakan matahari). Sehingga pada penelitian ini, penulis melakukan perancangan alat solar tracker yang berguna untuk meningkatkan efisensi tegangan yang dihasilkan oleh panel surya. Dengan menggunakan sensor LDR dan motor servo sehingga dapat membuat panel surya mengikuti arah datangnya cahaya matahari dan monitoring melalui Thingspeak untuk mengukur perbedaan tegangan yang dihasilkan oleh panel surya statis dan panel surya dengan sistem tracking (dinamis). Dengan membandingkan pengukuran tegangan dan arus pada alat Solar Tracker yang dibuat dengan panel surya statis, didapatkan hasil penelitian yang mampu menghasilkan efisiensi Daya lebih pada Solar Tracker sebesar 19,49% dibandingkan dengan panel surya statis. Kata kunci : Panel surya , energi matahari, sensor LDR, servo
