“…However, the overall aim of risk assessment is to identify and manage risks to ensure the safe and reliable operation of the activity, system, or project being assessed [32], [35]- [36]. Conducting a risk assessment for FSPV systems requires tools to identify potential hazards, evaluate the likelihood and consequences of each hazard, and develop effective mitigation strategies, as shown in Figure 4 [37], [38]- [43]. The scope of risk assessment and policy development for FSPV typically includes technical, financial, environmental, social, and regulatory risks [21].…”

This study provides a comprehensive overview of the risks and challenges associated with floating solar photovoltaic (FSPV) systems while identifying the best ways to promote the growth and success of this promising technology. Using a hazard identification and risk assessment methodology, this study categorizes risks into environmental, technical, regulatory, economic, and social risks. A risk assessment was conducted to determine the potential risks of a small-scale FSPV system in Philippine Lakes. Risks with high probability of occurrence and severity include health and safety, stability, installation and maintenance costs, and corrosion. This study proposes recommendations for mitigating these risks. This study also examines policies and programs from various countries that have successfully promoted the adoption of FSPV technology. Currently, countries such as China, Japan, and South Korea account for over 90% of the FSPV deployments. This study highlights the programs and incentives that accelerated FSPV deployments in these countries, such as the standard Feed-In-Tariff (FIT) "Build Plan," "Top Runner Program, and poverty alleviation program in China, significant FITs in Japan, and revised Renewable Portfolio Standards (RPS) and research and development (R&D) support in South Korea. Overall, this study provides valuable insights for policymakers, industry stakeholders, and other interested parties in the ongoing discussions of FSPV systems. Despite the risks and challenges associated with FSPV, the potential of this technology to play a significant role in the transition to a low-carbon, sustainable future cannot be ignored.INDEX TERMS Floating solar photovoltaic system, risk assessment, policy formulation, risks, and challenges in floating solar.

“…Moreover, literature published by domestic and foreign scholars were searched using keywords such as offshore wind power, offshore photovoltaic, and offshore new energy projects. We obtained extensive articles on the risk assessment of these projects [6][7][8][9][10][14][15][16][17]. At the same time, the risk factors can be collected by referring to the conference reports of offshore new energy projects and case studies of existing offshore new energy projects.…”

“…A fuzzy comprehensive evaluation model was also constructed by combining the hesitant linguistic fuzzy sets, triangular fuzzy sets, and analytic network process (ANP) methods. Gao et al [15] considered market risks, established an index system including economic, technical, environmental, and market risk factors, and established a comprehensive risk assessment framework for offshore PV projects under probabilistic language term sets. Considering the uncertainty of processing information and the confidence of expert judgement, Zhou et al [16] established a risk assessment model of China's offshore photovoltaic power generation projects with D-number and ANP method.…”

Hybrid offshore wind–solar PV power plants have attracted much attention in recent years due to its advantages of saving land resources, high energy efficiency, high power generation efficiency, and stable power output. However, due to the project still being in its infancy, investors will face a series of risks. Hence, a multi-criteria group decision-making framework for hybrid offshore wind–solar PV power plants risk assessment is constructed in this paper. Firstly, 19 risk indicators are identified and divided into five groups. Secondly, probabilistic linguistic term sets are then introduced to evaluate the criteria values to depict uncertainty and fuzziness. Thirdly, the expert weight determination model is built by combining subjective and objective weights based on expert information, the entropy and interaction-entropy measures of probabilistic linguistic term sets. Fourthly, the expert evaluation information is aggregated by transforming probabilistic linguistic term sets into triangular fuzzy numbers based on generalized weighted ordered weighted averaging operator. Additionally, the risk level is determined using the fuzzy synthetic evaluation method. Finally, the proposed method is applied to a case study and the risk level is slightly high with the similarity measure result of 0.938. Then, the risk indicator system and corresponding countermeasures can provide scientific reference for investment decisions and risk prevention.

“…In addition, some risk assessment studies related to photovoltaic and other new energy construction projects also provide a good reference for this paper. Regarding the construction of a risk indicator system, Jianwei Gao et al summarized the construction risks of offshore photovoltaic projects as economic, technical, environmental, and market risks [22]. Yunna Wu et al found that financing difficulties, unclear division of responsibilities and obligations, lack of operational experience, and material supply and installation defects are the most critical risk factors for photovoltaic poverty alleviation projects [23].…”

Building photovoltaic integration (BIPV) technology can effectively solve the urban energy shortage, environmental damage, and other environmental problems, which is of great significance to the sustainable development of the urban. However, the practical application of BIPV technology has been very slow, and BIPV projects have encountered numerous obstacles and risks in the process of promotion and construction. Although some researchers have conducted qualitative studies on these obstacles and risks, systematic risk assessment methods for BIPV projects are missing. This study aims to systematically develop a framework to assess the risk of BIPV projects to address this gap. First, a comprehensive risk indicator system is established using literature analysis and expert interview methods. Second, DEMATEL (decision-making trial and evaluation laboratory) is used to calculate constant rights. Then, the risk assessment is carried out from the perspective of four-dimensional risk including severity, possibility, urgency, and uncontrollability. The variable weight theory is used to calculate variable weight. The data fusion and risk level determination are realized by the matter-element extension model. Finally, a case study is conducted to verify the feasibility and applicability of the BIPV project risk assessment framework. The results show that the comprehensive risk grade of the BIPV project in Qingdao is III, which belongs to medium risk. In addition, some suggestions are made based on the evaluation results. This study can enrich the methods in the field of risk assessment, and the results can provide a valuable reference for BIPV project investors and decision-makers.
