Recent research has shed light on the significant impact of shading on the performance of solar power systems, presenting valuable insights for the energy sector. Conducted by Muhammad Dihyah Marwan from the University of Gadjah Mada in Yogyakarta, Indonesia, the study utilized PVsyst software to analyze how shading from nearby buildings affects the performance ratio (PR) of photovoltaic (PV) systems.
The research focused on two different designs of PV installations, each with specific tilt and azimuth angles—15 degrees and 0 degrees for Design-1 and Design-2, respectively. The positioning of the buildings, either to the north or south, played a crucial role in determining the energy output. The findings revealed that Design-1 achieved a higher performance ratio of 0.821 compared to 0.759 for Design-2. This indicates that the orientation and placement of solar panels are critical factors in maximizing energy production.
In addition to the technical analysis, the study also examined the financial implications of the PV installations. The payback period (PBP) for Design-1 was calculated at 8.1 years, with an impressive return on investment (ROI) of 140.5%. Design-2, while slightly less efficient, still presented a respectable PBP of 8.7 years and a 110% return rate. These financial metrics are essential for stakeholders in the energy sector, as they highlight the profitability of investing in solar technology, especially in urban environments where shading can be a concern.
Marwan emphasized the practical application of the research, stating, “The proposed method has been simulated and analyzed for application on the rooftop of the Teaching Industrial Learning Centre building at UGM.” This real-world implementation underscores the importance of considering shading effects in solar project designs, particularly in densely populated areas where buildings may obstruct sunlight.
The implications of this research extend beyond academic interest; they present commercial opportunities for solar energy developers and investors. By optimizing the design and positioning of solar panels to account for shading, companies can enhance energy output and improve financial returns, making solar investments more attractive.
This study was published in “e-Prime: Advances in Electrical Engineering, Electronics and Energy,” further contributing to the growing body of knowledge aimed at optimizing solar energy systems and fostering sustainable energy solutions. As the industry continues to evolve, research like Marwan’s will be crucial in guiding effective solar deployment strategies that maximize both performance and profitability.
