Optimization of the Residential Solar Energy Consumption Using the Taguchi Technique and Box-Behnken Design: a Case Study for Jordan

Abstract

In this paper, the Jordan's adoption of renewable energy, in general, and the solar energy, in particular, is overviewed. The solar energy development in Jordan, within the last decade, is highlighted from various aspects. Energy consumption and efficiency are major issues for nations such Jordan that have few natural resources and high energy costs, especially in the context of climate change. In Jordan, the industry with the highest energy use is residential construction. Residential building rooftop photovoltaic (PV) systems may address the issue of rising power needs and the need for more sustainable energy systems. This research contrasted present and projected residential household power usage with the potential electricity consumption from PV systems placed on the available roofs of residential structures. Taguchi and Box-Behnken Design (BBD) approaches were used to predict and optimize the yearly power usage using a design tool in Minitab version 18. The findings showed that the yearly energy usage was significantly influenced by solar cumulative installed PV power, sun shine hours, and operation service factors. The investigation revealed that the combined ideal elements and reactions meet the highest demands of the annual power usage of 8.0940 MWh per capita. The annual increase of PV plants, connected to the Jordan electric grid, refer to the availability of this area to adopt more and more PV projects. The available land, moderate climate, and reliable electric grid are encouraging factors to accepting large PV projects. The result showed that the yearly energy usage was significantly influenced by solar cumulative installed PV power, sun shine hours, and operation service factors. The investigation revealed that the combined ideal elements and reactions meet the highest demands of the annual power usage of 8.0940 (MWh per capita).
