Deteksi Debu pada Panel Surya. Alat Pemantau Efisiensi Solar Panel Berbasis IoT Blynk & Wokwi<\/strong><\/p>\n\n\n\n

Pada bagian ini akan dibahas pembuatan sistem pemantau ketebalan debu serta efisiensi daya pada panel surya (solar panel<\/em>) menggunakan mikrokontroler ESP32, sensor debu\/optik, sensor arus dan tegangan, serta sistem Internet of Things (IoT) dengan platform Blynk IoT pada software simulasi WOKWI. Skematik rangkaian ditunjukkan pada Gambar 1, program Arduino pada Kode 1, dan video pembuatan pada tautan Video 1. Tingkat penumpukan debu yang menghalangi intensitas cahaya matahari beserta penurunan efisiensi konversi daya diukur secara real-time<\/em>. Data hasil pengukuran dikirimkan ke aplikasi Blynk IoT untuk memberikan peringatan pembersihan panel surya secara otomatis guna menjaga performa daya keluaran tetap optimal.<\/p>\n\n\n
