Development of static solar panel equipped by an active reflector based on LDR sensors

Abstract

Solar panels are a very effective source of renewable energy in Indonesia. To increase the output power of solar panels, especially on the static solar panels, a reflector is required as an additional device. This paper describes development of a static solar panel equipped with an active reflector. Five LDR sensors are mounted on the top of the reflector, to detect the highest solar intensity. Meanwhile, a DC motor as a reflector drive system is mounted on the bottom of the reflector. The tilt angle of the solar panel is 450 to the negative x-axis and the reflector is 750 to the positive x-axis. The reflector will move in a semi-circular path, following the direction of the highest solar intensity detected by the LDR sensor. Three different reflectors used to optimize the output power, there are stainless steel, aluminium foil, and mirror. Solar panel with mirror reflector produces the largest output power compared to other reflectors. The output power of this device increases 1.6 times to the solar panels without reflector.

Comparative analysis of single-axis solar tracker performance with and without reflector under various weather conditions

“…In this study, the solar tracking system will be powered by a different source, namely the national electricity company (grid utility). The entire data display, including solar panel power output (P) and temperature [22], will be simulated simultaneously and compared between the static solar panel, the system of one-way solar tracking, and the solar panel with the system of one-way solar tracking and reflector addition [23], [24]. Subsequently, the power data obtained through measurements will be compared with the calculated power using (1) to determine the magnitude of the power differences produced [25].…”

Karakterisasi Sensor Arus Dan Tegangan Untuk Aplikasi Maximum Power Point Tracker Pada Sistem Penyimpanan Energi Listrik Panel Surya

“…Kemudian sensor juga memiliki tegangan offset yaitu 0,0544 V untuk sensor tegangan DC A dan 0,0564 V untuk sensor tegangan DC B. Hasil pengolahan data menunjukkan bahwa sensor tegangan DC A dan sensor tegangan DC B memliki kesalahan relatif sebesar 0,19% dan 0,20%. Nilai kesalahan relatif pada sensor ini lebih baik dibandingkan dengan kesalahan relatif hasil karakterisasi yang terdapat pada referensi [10],yaitu 0,77% dengan metode yang sama.…”
