Abstract

The economic and financial viability of large-scale solar power projects is a critical factor in the global transition to renewable energy. As solar energy continues to expand, evaluating investment risks, cost structures, regulatory challenges, and technological uncertainties is essential for optimizing project feasibility and long-term sustainability. This book chapter provides a comprehensive analysis of the key financial, policy, technological, environmental, and operational risks that impact the large-scale deployment of solar photovoltaic (PV) systems. The chapter explores capital expenditures, levelized cost of electricity (LCOE), policy and taxation uncertainties, advancements in solar PV and energy storage, and end-of-life management of solar panels. A structured risk assessment framework is presented to identify and mitigate financial losses, ensuring project bankability and investor confidence. The study further examines emerging trends in recycling technologies, risk-mitigation strategies, and smart grid integration to enhance the economic performance of solar energy systems. By addressing these challenges, the chapter aims to provide a roadmap for policymakers, investors, and industry stakeholders to foster financially viable and sustainable solar power initiatives.  

Introduction

The economic and financial viability of large-scale solar power projects is a crucial determinant in the global transition toward sustainable energy solutions [1]. As solar photovoltaic (PV) technology becomes increasingly cost-effective, large-scale solar installations have gained significant traction worldwide [2]. However, the feasibility of these projects is influenced by various financial, regulatory, and operational factors that must be carefully assessed to ensure long-term profitability [3]. While advancements in solar energy technology have improved efficiency and reduced costs, uncertainties related to capital investment, market dynamics, and policy frameworks continue to pose challenges [4]. A thorough understanding of these factors is essential for optimizing investment decisions and ensuring project sustainability in the evolving energy landscape [5]. 

Financial risks remain a primary concern for large-scale solar projects, as they involve high initial capital expenditures and long payback periods [6]. The cost of PV modules, inverters, grid infrastructure, and energy storage systems significantly impacts the overall project economics [7]. Additionally, fluctuations in material prices, supply chain disruptions, and changes in labor costs can influence financial projections [8]. Investors and stakeholders must consider factors such as the levelized cost of electricity (LCOE), return on investment (ROI), and power purchase agreements (PPAs) to assess the financial sustainability of solar ventures [9]. Economic uncertainties, including inflation, interest rate fluctuations, and market demand variations, add another layer of complexity to the financial planning of solar power projects [10]. 

Policy and regulatory frameworks play a crucial role in determining the viability of large-scale solar projects [11]. Government incentives, tax credits, feed-in tariffs, and renewable energy mandates influence project feasibility and investor confidence [12]. However, frequent changes in policies, delays in regulatory approvals, and bureaucratic hurdles can create uncertainties that hinder project development [13]. Inconsistent tax policies and reductions in subsidy programs may lead to financial losses for solar developers. Therefore, a stable and supportive regulatory environment is necessary to attract investment and accelerate the adoption of large-scale solar energy solutions [14]. Policymakers must also address challenges related to grid integration, land acquisition, and environmental compliance to streamline project implementation and enhance financial returns [15].
