Abstract

Keterbatasan sumber energi dari bahan fosil mengakibatkan pasokan ketahaan energi nasional harus memikirkan alternatif dengan pengembangan sumber energi baru terbarukan (EBT) salah satunya adalah sistem solar sel. Posisi Indonesia terletak garis khatulistiwa sangat diuntung karena mendapat paparan sinar matahari yang stabil sepanjang tahun. Karena itu sumber listrik tenaga surya atau solar sel ini sangat cocok digunakan di semua wilayah karena energi listrik yang dihasilkan relative merata. Saat ini penggunaan solar sel mulai dikembangkan sebagai salah satu alternative sumber pembangkit listrik. Penelitian ini bertujuan untuk penyelesaian permasalah diatas dengan membangun sistem solar sel diawali dari perancangan, pembuatan, analisis teknik & ekononom. Kapasitas beban listrik di dalam ruangan laboratorium dengan beban harian adalah 45Wh dan beban puncak 82 watt. Maka rancangan yang direkomendasikan adalah: panel surya 2 x 100Wp, BCR 40A, baterai 102Ah dan inverter 1500VA. Total biaya yang dibutuhkan selama umur investasi adalah Rp.18.857.700. Cara pengamatan yang dilakukan dengan pengambilan data intensitas cahaya yang terjadi selama 3 minggu di laboratorium. Peralatan yang digunakan adalah: luxmeter: mengukur intensitas cahaya, Tang Amper dan multimeter: mengukur tegangan dan arus sel surya. Hasil pengujian peralatan selama 2 hari berturut-turut: intensitas 8,781kLux maka tegangan panel sel surya adalah 12,1VDC, 220,2VAC dan arus dihasilkan adalah 2,0A. Intensitas cahaya paling tinggi terjadi pada tgl 16 Januari 2021 antara pukul 12.00 – 13.00 sebesar 80,3klux menghasilkan tegangan 12.1VDC, 220,2VAC dan arus listrik sebesar 3,2A. Kata Kunci: sumber energi, energi solar sel, panel sel surya./ The limitation of energy sources from fossil materials means that the national energy supply has to think about alternatives by developing new renewable energy sources (EBT), one of which is the solar cell system. Indonesia's position on the equator is very fortunate because it gets stable sun exposure throughout the year. Therefore, this source of solar power or solar cells is very suitable for use in all areas because the electrical energy produced is relatively even. Currently, the use of solar cells has begun to be developed as an alternative source of electricity generation. This study aims to solve the above problems by building a solar cell system starting from the design, manufacture, engineering & economic analysis. The capacity of the electrical load in the laboratory room with a daily load is 45Wh and a peak load of 82 watts. So the recommended designs are: 2 x 100Wp solar panel, BCR 40A, 102Ah battery and 1500VA inverter. The total cost required during the investment period is IDR 18,857,700. Observations were made by collecting light intensity data that occurred for 3 weeks in the laboratory. The equipment used is: luxmeter: measuring light intensity, Tang Amper and multimeter: measuring the voltage and current of solar cells. The results of testing the equipment for 2 consecutive days: intensity of 8.781kLux, the voltage of the solar cell panel is 12.1VDC, 220.2VAC and the resulting current is 2.0A. The highest light intensity occurs on January 16, 2021 between 12.00 - 13.00 at 80.3klux resulting in a voltage of 12.1VDC, 220.2VAC and an electric current of 3.2A. Keywords: energy sources, solar cell energy, solar cell panels
