This paper investigates customers’ willingness to buy potential bundle offers made up of an electric vehicle (EV) and community solar power. According to literature, the bundling of products with high complementarity in a single offering, such as EVs and solar power, can create added value for customers, resulting in a higher willingness to buy compared to a situation in which customers have to buy both products separately. Further, literature also suggests that the adoption of EVs and solar power can be increased by financial policy incentives. To test whether community solar adds value to EVs for customers, an experimental online survey that applied a within-subject design was conducted. Additionally, the experimental online survey was extended with a between-subject design to test for the effect of emphasizing financial policy incentives on willingness to buy the bundle. A representative sample of German customers (n = 488) provided empirical evidence for added value creation through bundling community solar with an EV in the form of a significantly higher willingness to buy the bundle compared to that for an EV alone. The between-subject analysis of the effect of emphasizing financial policy incentives revealed no further effects on customers’ willingness to buy the bundle. To increase the adoption of electric cars, practitioners should increasingly rely on combined offers of solar power and electric cars, while politicians should create a framework fostering the creation of such bundle offers on the supply side, instead of only providing financial incentives to consumers.

本文调查了客户购买由电动汽车（EV）和社区太阳能组成的潜在捆绑商品的意愿。根据文献记载，将电动汽车和太阳能等具有高互补性的产品捆绑在一起可以为客户创造附加值，与客户必须分别购买两种产品的情况相比，购买意愿更高。此外，文献还表明，通过财政政策激励可以增加电动汽车和太阳能的采用。为了测试社区太阳能是否为客户的电动汽车增加了价值，进行了一项实验性在线调查，该调查应用了受试者内部设计。此外，实验性在线调查通过主题间设计进行了扩展，以测试强调财务政策激励措施对购买捆绑销售商品的意愿的影响。代表德国的样本（n = 488）为通过将社区太阳能与电动车捆绑在一起而创造了增值创造的经验证据，与单独购买电动车相比，购买捆绑包的意愿明显更高。对强调财务政策激励措施影响的主题间分析表明，对客户购买捆绑产品的意愿没有进一步影响。为了提高电动汽车的普及率，从业人员应越来越依赖太阳能和电动汽车的综合报价，而政客应建立一个框架，促进在供应方创造此类捆绑式报价，
