Estimation and Sizing Analysis of Renewable Energy System

Abstract The primary research objective of this study is to estimate and size a renewable energy system, focusing on a residential building in one of the 36 states of Nigeria. A comparative analysis is employed to assess the estimation, sizing, and cost-benefit analysis of an integrated renewable energy system for the XX residential building in Kano, Nigeria, in comparison to uneconomical electricity tariffs. Kano, a rapidly developing city and commercial hub, has the largest population in northern Nigeria, with over 15 million residents. The data used in this study, including market information and item costs, were obtained from an e-commerce trading company and renewable energy experts with research and field experience. This research opens doors to identify the costs associated with installing solar energy systems in homes, thereby creating opportunities for oceanic growth. The study systematically enhances social productivity by providing uninterrupted backup power from an integrated renewable energy system. Economically, as discussed in the analysis, the costs of solar installation and maintenance are lower than the annual expenses incurred through electricity tariffs. However, it is important to note limitations within this study, such as the variability of primary and secondary data sources based on location and the projected costs of items used in the estimation and sizing analysis, which may differ across countries. Additionally, the costs of solar installation in homes are influenced by the types of loads, necessitating a comprehensive system analysis of both critical and non-critical loads to assess the economic viability and benefits of adopting an integrated renewable energy system to address the energy crisis.
