Abstract

Matahari merupakan sumber energi yang sangat berkaitan bagi kebutuhan manusia, dimana energi tersebut bisa didapatkan dari panas yang merambat sampai permukaan bumi, atau cahaya yang jatuh sampai permukaan bumi. Energi yang bersifat terbarukan mempunyai peran yang sangat penting dalam memenuhi kebutuhan energi mengingat sumber tersebut sangat melimpah. Hal ini disebabkan penggunaan bahan bakar untuk pembangkit-pembangkit listrik konvensional dalam jangka waktu yang panjang akan menguras sumber minyak bumi, gas dan batu bara yang makin menipis dan juga dapat mengakibatkan pencemaran lingkungan. Salah satunya upaya yang telah dikembangkan adalah Pembangkit Listrik Tenaga Surya (PLTS). Suatu alat tracking cahaya matahari dengan penampang yang dapat mengikuti arah datangnya cahaya, sehingga jika ditempatkan modul solar cell di atasnya, energi listrik yang dihasilkan lebih optimal dibandingkan dengan modul solar cell yang menghadap satu arah tertentu saja. Nilai arus maksimum 0,32A, nilai tegangan maksimum 13,74V, dan nilai daya maksimum 4,41W yang dihasilkan panel surya tracking lebih besar dibandingan nilai dari panel surya tanpa tracking dengan nilai arus maksimum 0,25A, nilai tegangan maksimum 11,95V, dan nilai daya maksimum 2,45W.

Abstract

Developments in the human life sector have progressed rapidly today, paralleled by the continuous advancement of technology. This trend is expected to significantly elevate the demand for electricity as one of the primary requirements. Currently, power plants heavily rely on petroleum as their main fuel source for electricity generation, contributing to environmental unfriendliness. In response to this, renewable energy has emerged as a viable solution to reduce dependence on petroleum fuel. One notable example of renewable energy is solar power, harnessed through Solar Power Plants. Research has been conducted to develop a transistor-based solar power plant using the 2N3055 model, with three variations in the distance of the Fresnel lens: 5 cm, 10 cm, and 20 cm over 14 days. The research yielded the highest output power, with an average voltage value of 13.868 V and a current value of 0.000038 A recorded on the 13th day. The power value reached 0.0005199 W on a prototype with a lens distance of 5 cm on the 14th day of research. This phenomenon occurs during sunny environmental conditions, leading to the transistor producing higher voltage and current due to focused light. However, different lens distances can result in improper focusing of light or even prevent light from reaching the transistors altogether, causing suboptimal electricity production or no production. Therefore, the influence of different Fresnel lens distances affects the light focusing on the transistor, consequently impacting the overall power output value.
