Abstract

Intensitas matahari menjadi parameter penting untuk mengetahui potensi energi di suatu lokasi. Pengukuran intensitas matahari sebagai sistem penggerak kerangka besar panel surya dapat menggunakan berbagai macam sensor. Sensor Phototransistor menjadi salah satu sensor cahaya yang memiliki kepekaan cahaya lebih besar dibandingkan dengan sensor cahaya yang lain. Sistem pelacakan arah cahaya matahari ini menggunakan empat sensor phototransistor yang diletakkan masing-masing dua sensor dibagian timur dan barat kerangka. Rangkaian sensor ini dibuat untuk bisa merespon posisi matahari dengan kuat pencahayaan 4710 Lux pada sudut kemiringan sensor sebesar 19,24◦. Untuk menguji akurasi dari sensor phototransistor dengan membandingkan hasil pengukuran pada rangkaian sensor dengan Lux Meter. Hasil pengujian menunjukkan bahwa sensor phototransistor memiliki rata-rata error pengujian sebesar 1,24% dan 1,27% pada sensor phototransistor timur dan 0,47% dan 0,93% pada sensor phototransistor barat.

The intensity of the sun becomes an important parameter to determine the energy potential in a location. Measurement of solar intensity as a large frame drive system for solar panels can use a variety of sensors. Phototransistor sensors become one of the light sensors that have greater light sensitivity compared to other light sensors. This sunlight direction tracking system uses four phototransistor sensors which are placed in each of the two sensors in the east and west of the skeleton. This sensor circuit is made to be able to respond to the position of the sun with 4710 Lux strong lighting at the sensor tilt angle of 19.24◦. To test the accuracy of the phototransistor sensor by comparing the measurement results on the sensor circuit with Lux Meter. The test results show that the phototransistor sensor has an average test error of 1,24% and 1,27% on the east phototransistor sensor and 0.47% and 0.93% on the western phototransistor sensor.
