In the bustling city of Arak, Iran, a groundbreaking solar power plant is not only harnessing the sun’s energy but also pushing the boundaries of solar technology design. Mohammad Parhamfar, an independent researcher and consultant in the electrical and energy fields, has recently published a comprehensive study in Solar Energy Advances detailing the intricate design of a 100-kilowatt rooftop solar power plant. This isn’t just any solar project; it’s a meticulous exploration of bifacial photovoltaic (PV) technology, which captures sunlight from both sides of the solar panels, maximizing energy yield.
The study, published in Solar Energy Advances, is a deep dive into the complexities of designing a PV power plant using PVsyst software, a widely used tool in the solar industry. Parhamfar emphasizes the critical role of the bifacial factor, a parameter that significantly influences the performance of bifacial PV systems. “Neglecting to properly configure this factor can lead to incorrect energy yield estimates and negatively affect the economic analysis of the designed project,” Parhamfar warns. This could have substantial commercial implications, as inaccurate estimations can lead to underperforming solar plants and financial losses for investors.
One of the key challenges Parhamfar addresses is accurately assessing the amount of radiation received from the rear of the panels. This involves optimizing row spacing to prevent shading and determining the effective installation angles and panel height to enhance bifacial efficiency. The study, based on a real project implemented in Arak, Iran, highlights the importance of incorporating climatic and environmental impacts into PVsyst for accurate performance prediction.
The research utilizes a suite of software tools, including AutoCAD, PVsyst, ETAP, PVLPC, Helioscope, and Volta, to address various design challenges such as field segment shading, solar energy availability in different months, nearby shading, roof configuration, wiring, cable design, grounding system, protection system calculation, risk assessment, lighting, and installation of lightning rods for shadow measurement. The economic analysis is conducted using RETScreen, a widely recognized software tool designed for evaluating the financial viability and performance of renewable energy and energy efficiency projects.
Parhamfar’s work is a testament to the evolving landscape of solar technology. As the energy sector continues to shift towards more efficient and sustainable solutions, the insights from this study could shape future developments in the field. By providing a practical example for designing a 100-kilowatt plant, Parhamfar’s research offers valuable guidance for engineers and consultants aiming to optimize bifacial PV systems. This could lead to more efficient solar power plants, reduced costs, and a more robust energy infrastructure.
The implications for the energy sector are vast. As solar technology continues to advance, the ability to accurately model and predict the performance of solar power plants becomes increasingly crucial. Parhamfar’s research not only enhances our understanding of bifacial PV systems but also sets a new standard for precision and efficiency in solar plant design. As we move towards a more sustainable future, innovations like these will be pivotal in driving the transition to renewable energy.
