The Sunyani Teaching Hospital (STH) in Ghana is on the brink of a transformative shift in energy management, as recent research highlights the potential for rooftop solar photovoltaic (PV) systems to revolutionize electricity generation in state-owned hospitals. Conducted by Nicholas Saddari from the Renewable Energy Department at the University of Energy and Natural Resources, this study meticulously assesses the technical and economic viability of implementing solar PV under Ghana’s newly adopted net metering scheme.
Ghana’s hospitals have long struggled with unreliable power supply and escalating electricity costs, which significantly hinder health service delivery. The study reveals that STH has a substantial installed load of 297,471 kW, with an annual energy demand reaching 1,493,326 kWh. In stark contrast, the proposed solar PV installation is projected to generate an impressive 9,418,145 kWh annually, offering a sustainable solution to the hospital’s energy woes.
Saddari emphasizes the economic benefits of this initiative, stating, “The financial analysis demonstrates that solar PV systems can provide a lucrative return on investment, with a net present value (NPV) of GHS 64.09 million and an internal rate of return (IRR) of 34%. This could be a game-changer for hospitals in similar contexts.” The study indicates that even with a modest 10% battery storage capacity, the economic metrics remain strong, showcasing an NPV of GHS 61.21 million and an IRR of 28%.
The environmental implications are equally compelling. The solar PV system is expected to save over 8 million kg of carbon dioxide annually, culminating in a staggering reduction of more than 200 million kg over its operational lifetime. This aligns with global sustainability goals and positions Ghana as a proactive player in the renewable energy landscape.
Moreover, the research presents a unique angle by incorporating carbon credit evaluations into the economic analysis. The findings suggest that factoring in carbon credits significantly enhances profitability, with an NPV of GHS 72.89 million without battery storage. This innovative approach could inspire similar assessments across the energy sector, paving the way for a broader adoption of renewable technologies.
The implications of this research extend beyond just one hospital. As Saddari notes, “Hospitals in developing countries can leverage rooftop solar PV systems not only to enhance health service delivery but also to foster energy independence.” This insight could catalyze a wider movement towards renewable energy solutions in healthcare facilities across the region.
The comprehensive analysis published in ‘Renewable and Sustainable Energy Transition’ (translated to English as ‘Renewable and Sustainable Energy Transition’) underscores a critical intersection of technology and economics in the energy sector. As Ghana continues to grapple with energy challenges, studies like Saddari’s illuminate a path forward, suggesting that solar energy could be the cornerstone of a more reliable and cost-effective healthcare infrastructure.
