本論文は、太陽光発電投資の事前評価のための包括的な分析枠組みを開発した。1982年から2023年にかけて太陽光パネル価格が99%低下したことを示し、補助金依存から市場競争力への移行を確認した。しかし、金融制約（85%）、技術的限界（75%）、規制の不確実性（70%）などの障壁が依然として存在する。提案された意思決定分析枠組みは、従来の評価手法のギャップに対処するものである。
English
This paper develops a comprehensive analytical framework for ex-ante evaluation of solar energy investments, showing a 99% reduction in solar module prices from 1982 to 2023, indicating a shift from subsidy dependence to market competitiveness. Despite this, barriers like financial constraints (85% relative importance), technical limitations (75%), and regulatory uncertainties (70%) persist. The proposed decision-analytical framework integrates technical performance with economic indicators to address gaps in conventional evaluation methods.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では太陽光発電の大量導入が進む中、本論文の枠組みは投資判断の高度化に寄与する可能性がある。ただし、日本の電力市場や規制環境に特化した分析ではないため、直接的な応用には調整が必要。
In the global GX context
This study offers a generalizable framework for solar investment evaluation that can inform global renewable energy policy and investment decisions, especially in regions with high solar insolation. It highlights persistent barriers and the need for modeling approaches that reconcile theoretical rigor with real-world complexities.
👥 読者別の含意
🔬研究者:Provides a structured framework for evaluating solar investments beyond simple LCOE comparisons, useful for researchers working on energy system models.
🏢実務担当者:Investors and project developers can use the framework to better assess solar project viability by integrating technical and economic indicators.
🏛政策担当者:Policymakers can consider the barriers identified (financial, technical, regulatory) to design more effective support mechanisms for solar integration.
📄 Abstract（原文）
The global transition toward decarbonized energy systems has positioned solar photovoltaic (PV) technology as a critical component of sustainable electricity supply. This study develops a comprehensive analytical framework for the ex-ante evaluation of solar energy investments by critically assessing three dominant economic modeling paradigms: least-cost generation expansion models, integrated energy system models, and macroeconomic assessment tools. Empirical analysis demonstrates a 99.0% reduction in global solar PV module prices between 1982 and 2023, signifying a decisive transition from subsidy-dependent deployment to market-driven competitiveness. Nevertheless, persistent barriers—notably financial constraints (85% relative importance), technical limitations (75%), and regulatory uncertainties (70%)—continue to impede optimal solar integration. We propose a novel decision-analytical framework that integrates technical performance metrics with dynamic economic indicators, addressing gaps in conventional evaluation methodologies. Findings indicate that while solar energy exhibits compelling economic potential—with levelized costs as low as USD 20–50/MWh in high-insolation regions—its successful integration requires modeling approaches that reconcile theoretical rigor with real-world policy and market complexities. Global solar investment reached USD 220 billion in 2023, a 175% increase since 2010, with China representing 55% of total deployment. This research provides actionable insights for policymakers, investors, and system planners navigating the evolving renewable energy landscape.
