日本語
ブラジルの住宅用PVモジュールを対象に、劣化・電力需要・消費者の交換判断を統合した技術経済モデルを構築。需要増加が早い世帯では11.7年・13.7年で交換閾値に達し、安定成長では27.6年・29.9年と大きく異なる。技術的寿命（29.6年）前に廃棄が加速する構造を示し、再利用・逆物流・リサイクル優先順位づけの意思決定支援を提供する。
English
This study builds a technical–economic model integrating module degradation, household electricity demand, and consumer replacement decisions for residential PV in Brazil. Under early-growth demand, replacement milestones arrive at 11.7 and 13.7 years versus 27.6 and 29.9 years under stable growth, showing demand dynamics can accelerate waste independent of degradation. It offers a scalable basis for reuse assessment, reverse logistics, and recycling prioritization.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではFIT終了後の大量廃棄・卒FIT太陽光の二次利用が2020年代後半の政策課題であり、需要側要因が廃棄時期を左右する本モデルの視点は、国内のPVリサイクル制度設計や循環経済政策の議論に示唆を与える。
In the global GX context
Globally, solar PV end-of-life and circular-economy management is rising on the agenda alongside the energy transition; this paper adds a demand-side behavioral lens to waste forecasting, complementing EU-focused PV recycling and extended producer responsibility debates.

📄 Abstract（原文）
This study develops a technical–economic model to support planning for second-life reuse and end-of-life management of residential PV modules in Brazil. The model integrates module degradation, residential electricity-demand dynamics, and consumer utility-based replacement decisions to identify temporal milestones at which modules remain technically functional but become vulnerable to premature replacement. By combining technical performance with consumer behavior, the model captures critical transition points between continued operation, replacement, and reuse pathways. Simulation results indicate that premature PV waste generation is highly sensitive to household consumption growth. Under early-growth demand profiles, users reach the attention and break-even milestones at 11.7 and 13.7 years, respectively, whereas under stable-growth profiles, these thresholds occur only at 27.6 and 29.9 years. This difference substantially increases the period during which modules may be replaced before reaching the estimated technical end-of-functional-life threshold of 29.6 years, demonstrating how demand-side dynamics can accelerate waste generation independently of module degradation. The findings indicate that integrating technical and economic criteria into planning decisions may help identify opportunities to extend module service life and reduce avoidable PV waste. The proposed model contributes to the waste-management literature by providing a scalable decision-support basis for reuse assessment, reverse logistics planning, recycling prioritization, and evidence-based policy development. More broadly, it may contribute to strategies that connect low-carbon energy transitions with circular economy principles and the United Nations Sustainable Development Goals (SDGs).
