パキスタンのカラチにおける住宅用太陽光発電（PV）システム4構成を技術経済・環境面で評価。フルバッテリー併設のケースCがNPV最高（25,104.3ドル）、回収期間約4年。ネットメータリングのケースDはLCOE最低（0.0307ドル/kWh）。完全太陽光依存で排出削減効果が最大。住宅PVが都市のエネルギー安全保障と気候緩和に有効と示唆。
English
This study evaluates four residential photovoltaic configurations in Karachi, Pakistan, for techno-economic and environmental performance. Case C (daytime PV with full battery backup) achieves the highest NPV of USD 25,104.3 with a payback period of about 4 years, while Case D (net metering) offers the lowest LCOE of USD 0.0307/kWh. Fully solar-dependent systems yield the greatest emission reductions, supporting residential PV as a viable pathway for urban energy security and climate mitigation.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の住宅用太陽光はFIT終了後の自家消費モデルへの移行が課題であり、本論文のバッテリー併設やネットメータリングの経済性比較は、日本の住宅PVの自立化や蓄電池導入の意思決定に示唆を与える。また、SSBJ開示におけるScope 2排出削減策としての再エネ導入評価にも参考になる。
In the global GX context
This study provides empirical evidence on the techno-economic viability of residential PV in a developing country context, offering insights for global energy transition discussions. The comparative analysis of battery backup and net metering configurations informs policy design for distributed solar adoption, relevant to ISSB and CSRD reporting on renewable energy investments and emission reductions.

📄 Abstract（原文）
Rising electricity prices, grid instability, and climate concerns are increasing the need for sustainable residential energy solutions in developing countries. This study evaluates four residential photovoltaic (PV) configurations for a household in Karachi, Pakistan, to identify a suitable option for sustainable urban energy transition and climate mitigation. The assessed systems include daytime PV with grid supply, daytime PV with 6 h battery backup and grid supply, daytime PV with full battery backup, and daytime PV with net metering. Energy requirements, installed capacity, area demand, and battery storage were calculated using household load data, while economic performance was assessed through payback period, net present value (NPV), and levelized cost of electricity (LCOE). Environmental benefits were evaluated using avoided CO2, CH4, and N2O emissions, and the best-performing system was further simulated in PVsyst. Case C, comprising daytime PV with full battery backup, achieved the highest NPV of USD 25,104.3 and a payback period of approximately 4 years. Case B achieved the second-highest NPV of USD 19,183.58 while providing a more practical balance between battery backup and grid support. Case D achieved the lowest LCOE of USD 0.0307/kWh. Fully solar-dependent configurations provided the greatest emission reductions. The findings support residential PV deployment as a practical pathway for improving urban energy security and reducing climate impacts.
