Abstract

This paper explores the potential of integrating solar panels into the road dividers of the South Luzon Expressway (SLEX) in the Philippines as a solution to address rising electricity costs and increasing energy demand. The main objective of this study is to assess the impact of incorporating solar panels into the SLEX and determine various aspects, such as the solar energy potential, the implementation costs, and the levelized cost of electricity (LCOE). Data from the Global Solar Atlas is utilized to assess solar irradiance and other environmental factors in the area. This study employed both Google Earth Pro and QGIS software applications for the analysis and assessment of the area. The simulation of the PV system was conducted using PVsyst software. This paper presents the array-losses analysis, system production, performance ratio, energy balances, and cost analysis. Integrating solar panels into the SLEX results in an annual energy production of approximately 49,930,381 kWh. Additionally, the analysis of the levelized cost of energy unveils a calculated value of 11.34 Php/kWh, representing a reduction in price compared to the current commercial cost of 11.91 Php/kWh for energy consumption. These findings indicate that the integration of solar PV systems in the SLEX road dividers contributes to clean electricity generation and reduces dependence on non-renewable sources by effectively lowering the cost of energy.
