A recent study led by Sonong Sonong from the Department of Mechanical Engineering at the State Polytechnic of Ujung Pandang has highlighted the potential of rooftop solar power plants (SPPs) to significantly reduce electricity consumption in hospitals, specifically the Makassar Eye Hospital. This research, published in the Journal of Scientific Synergy, showcases how solar energy can be effectively harnessed in urban settings, presenting both environmental and economic benefits.
The study begins by addressing the critical issue of electricity availability and consumption patterns at the Makassar Eye Hospital. By evaluating the solar radiation potential in the area, the research lays the groundwork for designing an efficient solar power system. Utilizing PVSyst software, a specialized tool for solar energy system design, the research team conducted a thorough technical analysis of energy generation and system performance.
One of the most compelling aspects of this research is its detailed economic analysis. The initial investment cost for establishing the rooftop solar power plant is estimated at approximately Rp. 544 million. The calculated energy production value is Rp. 1,278 per kilowatt-hour (kWh), leading to a Payback Period (PP) of 13.8 years. The study also calculated a Net Present Value (NPV) of Rp. 138 million, an Internal Rate of Return (IRR) of 11.51%, and a Return on Investment (ROI) of 25.4%. These figures indicate a sound financial investment, especially since the IRR exceeds the Discount Rate of 8.43%.
Sonong Sonong emphasizes the significance of these findings, stating, “The results affirm the plan’s feasibility, demonstrating that investing in solar energy can be both economically viable and beneficial for reducing operational costs in healthcare facilities.” This research not only highlights the financial incentives for hospitals to adopt solar energy but also opens up opportunities for solar technology providers, construction firms, and financial institutions looking to invest in sustainable infrastructure.
As the global energy landscape shifts towards renewable sources, the implications of this study extend beyond just the Makassar Eye Hospital. Other hospitals and commercial buildings can look to this model as a viable pathway to energy independence and cost savings. The findings underscore the growing importance of integrating renewable energy solutions into urban planning and development strategies.
In summary, the research conducted by Sonong Sonong demonstrates that rooftop solar power plants can be a practical and economically beneficial solution for healthcare facilities in Indonesia. As more institutions consider similar investments, the potential for growth in the renewable energy sector remains substantial, promising a cleaner and more sustainable future for urban energy consumption. This study was published in the Journal of Scientific Synergy, further contributing to the discourse on sustainable energy solutions.
