Abstract

Abstract This paper provides a solution for charging cell phones (HP) using solar panels. The need for electrical energy consumption is increasing, so renewable energy sources are needed that must meet the requirements, namely to produce energy that is environmentally friendly, at economical costs. The use of solar panels is a wise thing for current conditions as an alternative energy source to be used as a source of charging cell phones (mobile phones). The use of solar panels as a source of electrical energy to facilitate battery charging when outdoors or when there is no other power source. In this study, a solar panel of 10 Wp, 21V dc is used as a power source and a buck converter as a voltage reducer from 12V to charge a 6V, 4500 mAh battery. The number of cellphones that use this battery charger is 4, while observations when charging cellphones are in the form of battery percentage from 50% to 100% with a charging time of 1 hour 30 minutes. Makalah ini memberikan suatu solusi untuk mengisi batere Handphone (HP) menggunakan panel surya. Kebutuhan akan konsumsi energi listrik semakin meningkat, maka diperlukan sumber energi terbarukan yang harus memenuhi syarat untuk menghasilkan energi yang ramah lingkungan, biaya ekonomis. Penggunaan panel surya merupakan hal yang bijak untuk kondisi saat ini sebagai sumber energi alternative untuk dimanfaatkan sebagai sumber pengisian batere telepon seluler (handphone). Penggunaan panel surya sebagai sumber energi listrik untuk memudahkan pengisian batere saat berada di luar ruangan atau saat tidak ada sumber listrik lainnya. Pada penelitian ini menggunakan panel surya 10 Wp, 21V dc yang berfungsi sebagai sumber listrik dan buck converter sebagai penurun tegangan dari 12V untuk mengisi batere 6V, 4500 mAh. Jumlah handphone yang menggunakan sumber pengisi batere ini sebanyak 4, sedangkan pengamatan saat pengisian batere HP berupa persentasi batere dari 50% ke 100% dengan waktu pengisian 1 jam 30 menit.

Abstract

Modeling of the photovoltaic (PV) approach is generally described by nonlinear equations with solving the equation using the steps iteratively.  However, this proposed research discusses the monocrystal type PV module approach model to estimate the characteristics of a photovoltaic generator, because it has the advantage that it is good enough to operate in Indonesia. This approach model takes into account the relationship between power, energy, and current to obtain the performance characteristics of the PV generator. This PV generator approach model is compared with PV generator manufacturer data and analyzed to validate the proposed approach model. Approach model with simulation hope this helps to find out IV characteristics according to the data recorded on the PV module and can save time or reduce the time to measurement results. The simulation results obtained the amount of power, energy, and current, 200.475W, 133.65 W/m2, and 7.9 Amperes, respectively with a simulation time of about 1.5 milliseconds. In addition to the above results, a comparison between the current and the power of the PV modules under study is also given and it gives the result that at a certain current the power level will no longer increase, but the power will decrease drastically due to heat from the PV panel module, because the module has the ability to receive heat from outside.
