Abstract

Energi matahari merupakan energi terbarukan yang dapat menjadi alternatif dari kerterbatasan pasokan listrik yang ada jika tingkat pertumbuhan masyarakat semakin pesat. Melalui sel surya maka energi matahari dapat diubah menjadi energi listrik dalam bentuk tegangan/arus (DC). Namun ada beberapa faktor yang dapat mempengaruhi output dari panel surya, seperti besarnya tingkat intensitas cahaya dan suhu kerja dari panel surya. Di dalam Tugas Akhir ini akan dibuat sebuah alat pengisian baterai bertenaga surya menggunakan algoritma maximum power point perturb and observe. Untuk mengatur tegangan pengisian baterai digunakan buck converter. Dalam proses pengisian baterai, sistem akan mencari titik daya maksimum yang dapat dihasilkan oleh panel surya saat itu dengan mengatur duty cycle buck converter menggunakan mikrokontroler sebagai pusat kendali sistem. Hasil pengujian sistem charging battery dapat digunakan untuk mengisi baterai 12 Volt dengan tegangam minimum 12,4 Volt dan tegangan rata – ratanya 13,44 Volt, sedangkan arus maksimumnya 1,21 A, arus minimum 0,3 A dan arus rata-ratanya 0,71 A, proses charging battery berlangsung selama 2,55 jam. ============================================================================================= Solar energy is a renewable energy that can be an alternative to the lack of existing electricity supply if the rate of growth of society more rapidly. Through solar cells, solar energy can be converted into electrical energy in the form of voltage / current (DC). However there are several factors that can affect the output of solar panels, such as the magnitude of the light intensity level and the working temperature of the solar panels. In this Final Project will be made a solar powered charging device using the algorithm maximum power point perturb and observe. To set the battery charging voltage used buck converter. In the process of charging the battery, the system will look for the maximum power point that can be generated by the current solar panel by adjusting the duty cycle buck converter using the microcontroller as the control center of the system. The result of charging battery system test can be used to charge 12 Volt battery with minimum tegangam 12.4 Volt and average voltage 13.44 Volt, while maximum current is 1.21 A, minimum current 0.3 A and average current 0.71 A, the harging battery process lasts for 2.55 hours.
