An Evaluation of a Proposed Solar Plant System for Ceramics Production in Ghana
摘要
Ceramics are manufactured by firing clay materials at high temperatures in furnaces. High energy and fuel costs are the two main drivers leading to the decline of the ceramic sector of Ghana. Unlike countries such as China, Japan, the United Kingdom, and the United States of America, just to name a few, the cost of these resources is borne by the local manufacturers without any subsidy from the government. This results in high production costs thereby leading to the influx of imported cheap products from China, Japan, and the like. This study seeks to provide a snapshot of a proposed solar photovoltaic (PV) system for ceramics production which is consistent with the Ghanaian government’s aim to further develop the sector. The authors consider a solar PV system with battery storage connected on-grid as the most efficient and pragmatic solution for the manufacture of ceramics in Ghana. The solar irradiation levels of Tamale were used to size the solar PV system to meet the energy demand of the electric oven (E-oven). It was estimated that, the cost of electricity saved by supplying 60% of power from the solar PV system was GH¢164,721.60 (€9,336.62) per annum. The implementation of the study findings will lead to the attainment of United Nations Sustainable Development Goals (SDGs); namely: affordable and clean energy (SDG 7), industry, innovation, and infrastructure (SDG 9), responsible consumption and production (SDG 12) and climate action (SDG 13). In conclusion, the proposed design demonstrates the potential of solar energy as a sustainable alternative for the decarbonization of the ceramics industry.
