EFEKTIFITAS PENGISIAN BATERAI MENGGUNAKAN SOLAR PANEL 120 WP (WATTPEAK) DENGAN METODE PWM (PULSE WIDTH MODULATION) DI KAWASAN BALAI TAHURA BUNDER

Abstract

Electrical energy has become a basic need for humans today, almost all aspects of human life require electrical energy, starting from lighting, water pumps, air conditioning, cooking, even for vehicles in the future that will use electricity. The electrical energy needed so far has been produced from fossil energy which is not environmentally friendly and has dwindling reserves, alternative energy is needed that is environmentally friendly and sustainable, there are several energies that can be utilized, including water energy, wind energy, solar energy and so forth. Solar energy is one of the most abundant energies in nature, especially in Indonesia, with Indonesia passing by the equator, Indonesia has enormous energy reserves. This potential is expected to become Indonesia's future energy. Solar cell technology is very advanced with increasingly good efficiency, in addition to energy conversion by solar cells with photovoltaic technology, a method is also needed to store the results of the conversion into storage (battery) optimally. One of the battery charging technologies is the Pulse Width Modulation (PWM) method, with this method battery charging is optimal on a 120 WP solar panel. In this study, a 120 WP solar panel was used, a 65 Ah 12 Volt battery, a 40 Watt Dc 12 Volt load and a 10 Ampere PWM Solar Charger Controller (SCC). The system was running for 3 months from April to JUne, the load was turned on for 12 hours every day with a load absorption current of 3.9 Amperes.
