Maximizing Annual Energy Yield in a Grid-Connected PV Solar Power Plant: Analysis of Seasonal Tilt Angle and Solar Tracking Strategies

Abstract

Harnessing the abundant solar resources holds great potential for sustainable energy generation. This research paper delves into a comprehensive analysis of seasonal tilt and solar tracking strategy scenarios for a 15 MW grid-connected PV solar power plant situated in Kandahar province, Afghanistan. The study investigates the impact of fixed tilt, seasonal tilt, SAHST (single-axis horizontal solar tracking), and SAVST (single-axis vertical solar tracking) on energy yield, considering technical, economic, and environmental aspects. In the first scenario, a fixed tilt angle of 31 degrees was employed. The second scenario explored the use of seasonal tilt angles, with a summer tilt angle of 15 degrees and a winter tilt angle of 30 degrees. The third scenario analyzed SAHST. Finally, the fourth scenario focused on implementing SAVST. SAVST proved to be an exceptional solution, showcasing a remarkable increase in annual energy yield, and generating an additional 6680 MWh/year, 6336 MWh/year, and 5084 MWh/year compared to fixed, seasonal, and SAHST scenarios, respectively. As a result, surplus energy yielded an income of USD 554,440.00 per year compared to fixed tilt. However, the investment cost for the solar tracking system amounted to USD 1,451,932, accompanied by an annual operation and maintenance cost of 0.007 USD/W/year. The analysis revealed a promising payback period of 3 years, confirming the economic feasibility of this investment. The findings underscore the effectiveness of different strategies for optimizing solar power generation in the Kandahar region. Notably, the installation of SAVST emerged as an influential solution, significantly increasing power production. These research outcomes bear practical implications for solar tracking strategies for addressing the load challenges faced by Kandahar province and offer valuable insights for the operators and operation of solar power plants in similar regions.

Optimal Grid Flexibility Assessment for Integration of Variable Renewable-Based Electricity Generation

“…The power network in this region is interconnected with Uzbekistan, Tajikistan, and Turkmenistan, facilitating cross-border electricity exchanges. In 2022, the NEPS possessed 484 MW of installed capacity, received an import of 465 MW of power, and encountered a demand for 3254 MW [19].…”

“…This research paper aims to address these critical issues within the context of Afghanistan's power system [19]. Focusing on the integration of solar and wind energy, we assess the optimal grid flexibility options that can enable Afghanistan to tap into its renewable energy potential while maintaining a stable and reliable electricity supply [20].…”

Techno-Economic Appraisal of A Rooftop Solar Pv Project for A University Campus

“…PVsyst is a well-known and industry-standard software application for modeling and simulating the operation and performance of photovoltaic (PV) system (Zaheb et al, 2023). By inputting relevant parameters such as solar PV panel specifications, system capacity, geographical location, and local weather data specific to UiTM Shah Alam, PVsyst generated informative reports and metrics.…”
