Abstract
Kebutuhan akan sumber energi terbarukan semakin meningkat seiring terbatasnya cadangan energi fosil dan meningkatnya kesadaran terhadap isu lingkungan. Panel surya merupakan salah satu solusi energi terbarukan yang populer, namun efisiensinya sangat dipengaruhi oleh sudut datang sinar matahari. Penelitian ini bertujuan untuk merancang dan mengimplementasikan sistem solar tracker dua sumbu (dual-axis) yang mampu mengikuti pergerakan matahari secara otomatis dan dilengkapi fitur pemantauan berbasis Internet of Things (IoT) menggunakan platform Blynk. Sistem ini memanfaatkan empat sensor LDR untuk mendeteksi intensitas cahaya dari empat arah, dua motor servo sebagai aktuator penggerak panel surya, Arduino Nano sebagai pengendali pelacakan, dan ESP32 sebagai pengirim data ke aplikasi Blynk. Pengukuran parameter kelistrikan dilakukan oleh sensor INA219 pada sisi DC dan sensor PZEM-004T pada sisi AC. Data seperti tegangan, arus, dan daya ditampilkan secara real-time melalui jaringan WiFi ke dashboard aplikasi. Hasil pengujian menunjukkan bahwa sistem pelacak mampu mengarahkan panel mengikuti posisi matahari dengan akurasi responsif. Sensor INA219 mencatat tingkat akurasi rata-rata sebesar 93,84% dan error sebesar 6,83%, sedangkan sensor PZEM-004T mampu mendeteksi arus AC dengan perbedaan nilai yang masih dalam batas toleransi. Sistem pemantauan berbasis IoT terbukti berjalan stabil, dengan latensi rendah dalam pengiriman data ke aplikasi Blynk. Dengan integrasi antara pelacakan otomatis dan pemantauan real-time, sistem ini dapat memberikan kemudahan dalam pengawasan performa sistem secara jarak jauh melalui perangkat mobile. ***** The demand for renewable energy sources continues to rise due to the limited availability of fossil fuel reserves and growing awareness of environmental issues. Solar panels are one of the most popular renewable energy solutions; however, their efficiency is greatly affected by the angle of incoming sunlight. This study aims to design and implement a dual-axis solar tracker system capable of automatically following the sun’s movement and equipped with an Internet of Things (IoT)-based monitoring feature using the Blynk platform. The system utilizes four LDR sensors to detect light intensity from four directions, two servo motors as actuators to adjust the solar panel position, an Arduino Nano as the tracking controller, and an ESP32 to transmit data to the Blynk application. Electrical parameters are measured using the INA219 sensor on the DC side and the PZEM-004T sensor on the AC side. Data such as voltage, current, and power are displayed in real-time via a WiFi network on the application dashboard. Testing results show that the tracker system can accurately and responsively adjust the panel to follow the sun’s position. The INA219 sensor recorded an average accuracy rate of 93.84% with an error of 6.83%, while the PZEM-004T was able to measure AC current with a deviation still within acceptable limits. The IoT-based monitoring system demonstrated stable performance and low latency in transmitting data to the Blynk application. With the integration of automatic tracking and real-time monitoring, the system offers convenience in remotely supervising the system’s performance via mobile devices.
