POTENTIAL OF ROOFTOP SOLAR ENERGY SYSTEMS FOR LIVESTOCK HOUSING

Аннотация

INTRODUCTION As global energy demands continue to rise, so does Rooftop solar photovoltaic (PV) systems have the need for sustainable, renewable energy sources gained widespread recognition in recent years as to reduce dependence on fossil fuels and mitigate an efficient means of harnessing solar energy in environmental impacts. The agricultural sector, a various sectors, from residential to industrial. significant energy consumer, has been particularly However, the potential of installing these systems impacted by rising energy costs, urging on livestock facility rooftops remains stakeholders to seek alternative, cost-effective, and underutilized, despite several advantages. environmentally friendly energy solutions. Within Livestock houses often feature expansive, agriculture, livestock farming requires unobstructed roofs with optimal sunlight considerable energy for heating, cooling, exposure, making them ideal candidates for solar ventilation, and lighting. Traditionally, these energy generation. Integrating solar PV systems on demands have been met through conventional these rooftops offers livestock operations an energy sources, which contribute to greenhouse opportunity to generate clean energy onsite, thus gas emissions and operational costs. Adopting reducing reliance on external energy sources and renewable energy technologies, particularly solar enhancing energy self-sufficiency. energy, can address these issues while aligning This study aims to assess the potential for rooftop with global sustainability goals. solar energy systems on livestock facilities, focusing on technical, economic, and https://www.theamericanjournals.com/index.php/tajabe 5 THE USA JOURNALS THE AMERICAN JOURNAL OF AGRICULTURE AND BIOMEDICAL ENGINEERING (ISSN – 2689-1018) VOLUME 06 ISSUE11 environmental factors. Key considerations include viability of installing rooftop PV systems on roof orientation and surface area, solar irradiance livestock facilities. Installation costs were levels, installation costs, and expected energy estimated based on panel type, structural output. Additionally, this research evaluates the requirements, and installation labor. We calculated potential economic benefits, such as reduced potential cost savings based on the current energy energy costs, return on investment, and expenditures of the livestock facilities, considering government incentives, along with the system's the amount of energy that could be offset by the PV impact on animal welfare by contributing to more systems. Additionally, we incorporated available stable internal climate conditions. By examining government incentives, such as tax credits and these factors, this study provides a framework for grants, that could reduce installation costs and livestock farmers and industry stakeholders to improve return on investment (ROI). By estimating make informed decisions about solar energy payback periods and net present value (NPV), we adoption, contributing to more sustainable and were able to provide a comprehensive economic cost-effective livestock management practices. analysis for livestock operators considering solar adoption.
