本研究は、大規模太陽光発電所の経済・環境・社会の多次元持続可能性を評価する統合監査プロトコルを提案する。LCOEや投資回収期間などの経済指標、炭素削減・水使用・生物多様性の環境指標、労働十分性指数などの社会指標を標準化。太陽光技術やアグリボルタイクス等の緩和策も提示し、開発者・政策立案者の意思決定を支援する。
English
This study proposes a standardised auditing protocol integrating economic, environmental, and social benchmarks for utility-scale solar PV sustainability. It defines LCOE (RM 0.24–0.48/kWh), payback (4–8 years), carbon mitigation (700–800 tCO2/MW/yr), water use (20 L/MWh), and a Labour Sufficiency Index (0.7 workers/MW). Mitigation strategies include agrivoltaics and passive cooling, supporting evidence-based decisions.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではFIT/FIP制度下で大規模太陽光の導入が進み、地域との共生や環境影響評価が課題となっている。本フレームワークは、事業者のESG開示や自治体の環境アセスメント基準の参考になり得る。
In the global GX context
As global solar deployment accelerates, this framework addresses the lack of standardised sustainability auditing for utility-scale PV. It aligns with growing demands for comparable ESG metrics in project finance and could inform disclosure under TCFD/ISSB for renewable assets.

📄 Abstract（原文）
The rapid worldwide deployment of utility-scale solar photovoltaic (PV) systems highlights the need for an integrated concept to evaluate their multidimensional sustainability performance. This study introduces a novel auditing protocol that combines economic, environmental, and social benchmarks into a standardised module, addressing the current fragmented approaches. Realistic benchmarks are conceived by methodically synthesising industry datasets, peer-reviewed literature, and regulatory guidelines. With a payback period of 4 to 8 years and a benchmark LCOE between RM 0.24 and RM 0.48/kWh, economic analysis confirms strong financial viability under current market conditions. Financial viability is indicated by benefit-cost ratios greater than 1.0. Environmental audits suggest a biodiversity restoration goal of at least 1000 trees replanted per MW and quantify a carbon mitigation potential of 700–800 tonnes of CO 2 /MW/year. A benchmark of 20 L per MWh is used to regulate water consumption, encouraging careful resource management. A minimum workforce ratio of 0.7 workers/MW, or roughly 35 employees for a 50 MW facility, is recommended by the Labour Sufficiency Index, which is established by social assessment. This will guarantee beneficial labour practices and operational stability. Additionally, the study offers focused mitigation strategies in every aspect, such as advanced photovoltaic technologies, integration of agrivoltaics, passive cooling systems, and rainwater harvesting measures. Comparability, accountability, and decision-making are enhanced by incorporating these sustainability metrics into a scalable and cohesive framework. The proposed approach provides solar engineers, researchers, developers, and policymakers with evidence-based decision-making for sustainability assessment and performance tracking of utility-scale PV systems.
