1. INTRODUCTION

   The worldwide energy industry is currently experiencing a significant overhaul in reaction to growing environmental worries and the urgent need to address climate change. This trend has resulted in an increasing emphasis on shifting towards energy sources that are both sustainable and resilient. Solar energy, derived from sunshine, has become a crucial factor in this shift, influencing the future of worldwide energy systems and efforts to protect the environment. IRENA highlights the abundant and ample supply of solar energy, as the Earth's surface receives a substantial amount of sunshine that can meet global energy demands numerous times over (IRENA, 2022). The inherent abundance of solar energy makes it a viable and sustainable long-term solution for addressing energy security challenges.

   The efficiency and affordability of solar energy systems, specifically photovoltaic (PV) and concentrated solar power (CSP) technologies, have been greatly enhanced by technological developments. The progress in solar energy technology has been instrumental in the extensive acceptance of solar power in several sectors, such as residential, commercial, and industrial uses (Hoffmann et al., 2020). The significance of solar energy in reducing the effects of climate change cannot be exaggerated. The IPCC underscores the imperative of shifting towards renewable energy sources, namely solar power, to alleviate greenhouse gas emissions and restrict global warming (IPCC, 2021). The deployment of solar energy is in line with global sustainability objectives, including the United Nations Sustainable Development Goals (SDGs), namely Goal 7, which seeks to guarantee universal access to inexpensive and environmentally friendly energy.

   Effective energy management is crucial for promoting sustainable development and tackling worldwide energy issues. In recent years, solar power has become a prominent candidate in the search for efficient and eco-friendly energy solutions (Smith et al., 2019). The use of photovoltaic (PV) and concentrated solar power (CSP) technologies has revolutionized the energy industry by providing environmentally friendly, renewable, and plentiful sources of electricity. Solar power's effective energy management involves a complete strategy that focuses on maximizing the utilization and deployment of solar energy systems. The goal is to optimize energy output, improve system efficiency, and contribute to overall energy sustainability.

   In the midst of the worldwide shift towards a low-carbon economy and the exploration of alternatives to fossil fuels, solar power has become increasingly important due to its numerous advantages. Solar energy solutions decrease dependence on limited resources and alleviate the release of greenhouse gases and air pollutants, so promoting environmental preservation endeavors. Efficient utilization of solar electricity necessitates the implementation of effective energy management strategies. These strategies encompass optimizing system design, monitoring performance, implementing maintenance practices, integrating energy storage solutions, managing grid interactions, and establishing policy frameworks that promote the adoption of solar energy (DOE, 2022).

   This review article attempts to explore the increasing importance of solar energy as a reliable and environmentally friendly source of electricity. The study will investigate technological advancements, economic feasibility, environmental benefits, and regulatory structures related to the exploitation of solar energy and effective energy management. This review aims to contribute to the ongoing discussion on sustainable energy transitions and the important role of solar energy in crafting a more sustainable future by analyzing important trends and obstacles.

   3. Economic feasibility

      In recent years, the economic feasibility of solar energy has significantly improved due to the decreasing costs of solar photovoltaic (PV) modules and installation. The research carried out by the International Energy Agency (IEA) emphasizes this pattern, suggesting a significant reduction in costs for solar photovoltaic (PV) systems (IEA, 2021). The decrease in expenses has had a transformative effect, as it has rendered solar energy more and more competitive with conventional fossil fuels in numerous areas. Consequently, solar power is currently regarded as a feasible and appealing alternative for fulfilling energy needs while simultaneously tackling environmental issues associated with carbon emissions and climate change. Moreover, research that specifically examines the levelized cost of electricity (LCOE) for solar energy projects presents convincing proof of the cost-efficiency and enduring advantages linked to solar power generation.

      The LCOE analysis takes into account multiple aspects, including the original capital outlay, ongoing operational and maintenance expenses, and the expected lifespan of solar installations. Studies constantly show that solar energy has a more favorable levelized cost of electricity (LCOE) compared to conventional energy sources such as coal or natural gas. This not only establishes solar power as a financially feasible option, but also strengthens its contribution to attaining energy sustainability and transitioning to a more environmentally friendly energy future. The declining costs of solar photovoltaic (PV) systems, along with positive estimates of levelized cost of electricity (LCOE), have stimulated substantial expansion and investment in solar energy projects worldwide. There is a growing awareness among governments, businesses, and consumers about the economic benefits of solar energy. This has resulted in a significant increase in the number of solar installations and a transition towards using renewable energy sources. This paradigm shift not only enhances the economy through job creation and fostering innovation in the solar sector, but also has a positive impact on environmental objectives by mitigating greenhouse gas emissions and advocating for sustainable energy policies.
