車載型太陽光発電（VIPV）の商用評価が「運用現実ギャップ」により根本的に歪んでいることを、2015〜2026年の文献統合で示す。都市峡谷では部分陰影が実発電量を50%以上減らし、MPPT損失も約35%に達する。航続距離延長ではなく、低電流トリクル充電による電池劣化抑制と系統ピーク需要低減こそが本質的価値だと主張し、動的条件を定量化する「Solar-Automotive Standard」の標準化を求める。
English
This review synthesises 2015-2026 literature to show that commercial assessments of Vehicle-Integrated Photovoltaics suffer an 'operational reality gap': urban-canyon shading cuts real-world yields by over 50% and MPPT losses reach ~35%. It argues VIPV's core value is not range extension but battery preservation via solar trickle charging, reducing cycle aging and peak grid demand. The authors call for a standardised 'Solar-Automotive Standard' quantifying dynamic performance.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の自動車産業はEV・SDV戦略と系統安定化の両立を迫られており、VIPVの実効性評価は車載電源の資産価値・LCA開示にも波及する。SSBJのScope 3や製品カーボンフットプリント議論と接続しうる論点を提供する。
In the global GX context
For global GX, this paper reframes transport decarbonisation around grid-interactive assets and battery longevity rather than headline range figures, feeding into CSRD/ISSB product-level disclosure and transition-finance narratives on EV value retention. It also highlights a standards gap that could shape future automotive sustainability metrics.
👥 読者別の含意

📄 Abstract（原文）
The rapid electrification of the global transport sector requires a shift towards decentralised energy solutions to mitigate grid instability, a challenge for which the UK's net-zero transport policy provides a pressing case study. Vehicle-Integrated Photovoltaics offers a potential remedy, yet this review argues that current commercial assessments are fundamentally flawed due to an "operational reality gap." By synthesising literature from 2015-2026, the paper demonstrates that Standard Test Conditions fail to account for the complex “3D solar resource” encountered by curved vehicle surfaces in dynamic environments. The analysis identifies that in 'urban canyons', partial shading itself can reduce real-world yields by over 50% compared to theoretical models, an effect compounded by rapid irradiance fluctuations that cause standard Maximum Power Point Tracking algorithms to lose roughly 35% of the already-available power. Crucially, this study challenges the industry's singular focus on range extension. Instead, it establishes that the primary value of Vehicle-Integrated Photovoltaics could lie in battery preservation. Emerging evidence confirms that solar trickle charging, continuous low-current charging, can significantly mitigate battery cycle aging and reduce peak grid demand. The review concludes that for Vehicle-Integrated Photovoltaics to transition from niche prototypes to the mass market, the automotive industry must abandon stationary photovoltaic ratings. Commercial viability requires the adoption of a standardised "Solar-Automotive Standard" that accurately quantifies performance under the dynamic conditions that Vehicle-Integrated Photovoltaics operate in, ensuring that consumer expectations align with actual output.
