本論文は、電気自動車とオフグリッド太陽光発電システムをバンドルした販売モデルを提案し、ゲーム理論を用いて分析する。米国とドイツのデータに基づくシナリオ分析により、バンドルがEV普及を促進し、石油依存度を低減することを示す。ドイツでは石油依存低減が7.8ポイント向上し、ライフサイクル排出量も米国で11%、ドイツで29%削減される。高地金市場で特に有効であり、バッテリーコスト低下により低地金市場でも普及が期待される。
English
This paper proposes a bundled sales model integrating electric vehicles with off-grid solar PV systems, analyzed via sequential game theory. Scenario analysis calibrated to U.S. and German data shows bundling accelerates EV adoption, reduces oil dependency (by 7.8 percentage points in Germany to 34.5%), and yields lifecycle emission reductions of 11% (U.S.) and 29% (Germany). The model is particularly advantageous in high-tariff markets, with declining battery costs expected to trigger a tipping point in lower-tariff markets.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は高電力料金と豊富な太陽光資源を有し、本モデルが示すバンドル販売戦略は、EV普及と家庭のエネルギー自給率向上に有効な可能性がある。日本の電気事業者や自動車メーカーは、SSBJ開示や統合報告書での脱炭素戦略の一環として検討すべき実証済みの手法である。
In the global GX context
Globally, the bundled EV-solar model offers a pathway to reduce grid dependency and emissions in high-tariff markets, aligning with ISSB and CSRD climate-transition strategies. The findings support decarbonization efforts by promoting household energy self-sufficiency and reducing reliance on carbon-intensive grids, which is relevant for companies reporting under TCFD or SEC climate rules.

📄 Abstract（原文）
High electricity prices remain a substantial barrier to electric vehicle (EV) diffusion. To address this challenge, we propose a bundled sales model that integrates EVs with distributed, operationally off-grid photovoltaic (PV) systems for self-consumption. Using a sequential game-theoretic framework and scenario analysis calibrated to U.S. and German data, we show that, within the calibrated scenarios and declared system boundaries, bundling accelerates EV adoption and reduces modeled oil dependency, measured as the physical volume of fossil fuel displaced by the bundled fleet. In Germany, bundling increases oil-dependency reduction by 7.8 percentage points, to 34.5%, relative to the traditional unbundled model. The bundled model also delivers stronger decarbonization, yielding incremental lifecycle emission reductions of 11% in the U.S. and 29% in Germany under the declared system boundary. Three insights follow. First, bundling is especially advantageous in markets with high grid tariffs, strong solar irradiance, or falling PV costs. Second, decoupling EV charging from carbon-intensive grids promotes household energy self-sufficiency and helps households become more resilient energy prosumers. Third, the threshold analysis indicates that the model is already viable in high-tariff markets such as Germany, while declining battery costs are likely to trigger a tipping point in lower-tariff markets such as the U.S., supporting a gradual diffusion pattern from suburbs to cities. These findings identify a viable pathway for low-carbon transport transitions through synergistic EV–solar integration.
