[ABSTRAK
Pemanfaatan panel surya untuk membangkitkan energi listrik terus meningkat diseluruh dunia termasuk Indonesia. Umumnya panel surya dipasang pada suatu strukturpenyangga yang dihadapkan dalam sudut tertentu yang tetap terhadap arah kedatangancahaya matahari. Metode pemasangan seperti ini berakibat menurunnya efisiensi energilistrik yang dibangkitkan karena arah kedatangan cahaya matahari berubah setiap hari. Untukmengatasi permasalahan ini perlu ada peralatan yang berfungsi untuk mengarahkan panelsurya sesuai arah kedatangan cahaya matahari yang disebut solar tracker. Dalam penelitianini, dikembangkan prototipe solar tracker dua sumbu. Solar tracker yang dikembangkanterdiri dari dua buah motor DC penggerak arah azimuth-elevasi, sun sensor yang terdiri darilima fotodioda, struktur mekanik penyangga, mikrokontroler dan sistem pengendali.Penggunaan lima fotodioda dalam penelitian ini dimaksudkan untuk menekan biayapembelian sun sensor yang harganya relatif mahal di pasaran. Dalam penelitan ini, prototipesolar tracker sudah diujikan dengan menggunakan cahaya buatan dengan intensitas yangmendekati cahaya matahari. Dari hasil pengujian, solar tracker sudah dapat bekerja denganmemadai meskipun pengujian di bawah cahaya matahari langsung perlu dilakukan.
ABSTRACT
Utilization of solar panels to generate electricity is increasing throughout the world ,including Indonesia . Generally, solar panels mounted on a support structure that is exposedin certain fixed angle to the direction of arrival of the sun. This installation method as theresulting decline in the efficiency of electrical energy generated because of the direction ofarrival of sunlight changes every day . To overcome this problem, there needs to beequipment that is used to steer the direction of arrival of solar panels called solar sun tracker .In this study , developed a prototype two- axis solar tracker . Solar tracker is developedconsisting of two DC motors driving toward azimuth - elevation , sun sensor consists of fivephotodiode , the mechanical structure of the buffer , the microcontroller and control systems .The use of five photodiode in this study is intended to reduce the cost of purchasing a sunsensor which is relatively expensive on the market . In this research , prototype solar trackerhas been tested by using artificial light with an intensity that is closer to the sun. From the testresults , the solar tracker has been able to work with adequately despite testing under directsunlight needs to be done ., Utilization of solar panels to generate electricity is increasing throughout the world ,including Indonesia .
