In the heart of Indonesia, a groundbreaking initiative is set to revolutionize the way we think about energy consumption and sustainability. Raihan Putri, a dedicated researcher from the Department of Electrical Engineering at Malikussaleh University in Lhokseumawe, has spearheaded a project that could significantly reduce reliance on conventional electrical sources. The project, published in the Majlesi Journal of Electrical Engineering, focuses on the design and implementation of a solar power system for SDN 023905 Binjai, a school that currently draws its entire electrical supply from the state-owned electricity company, PLN.
Putri’s research delves into the intricacies of harnessing solar energy, a virtually limitless and abundant resource. The proposed on-grid solar power plant (PLTS) aims to install a 1.2kWp system on the roof of SDN 023905 Binjai. This system will comprise four 300Wp solar panels connected in series, along with a 1.2 kW to 3 kW inverter. The meticulous planning and analysis behind this project ensure optimal functionality and a Performance Ratio (PR) of 84%, well above the minimum benchmark of 70%.
The financial implications of this project are equally compelling. With an initial investment cost of IDR 31,555,222, the payback period is remarkably swift, occurring within the first year and month of the PLTS’s 20-year operational lifespan. This swift return on investment underscores the economic viability of solar power systems, making them an attractive option for both public and private sectors.
“Our goal is to reduce the reliance on conventional electrical sources at SDN 023905 Binjai,” Putri explains. “By integrating a solar power system, we not only contribute to environmental sustainability but also demonstrate the feasibility and benefits of renewable energy solutions.”
The successful implementation of this project could pave the way for similar initiatives across Indonesia and beyond. As the demand for renewable energy sources continues to grow, the insights gained from this research will be invaluable. The energy sector stands to benefit significantly from the adoption of solar power systems, which offer a sustainable and cost-effective alternative to traditional energy sources.
Putri’s work, published in the Majlesi Journal of Electrical Engineering, which translates to the ‘Majlesi Journal of Electrical Engineering’ in English, highlights the potential of solar energy to transform the energy landscape. By showcasing the feasibility and economic benefits of solar power systems, this research could inspire future developments in the field, driving innovation and sustainability in the energy sector.
