Households adopt solar panels for different reasons, but usually with a reduced electricity bill in mind. However, the access to solar power at near zero marginal costs may well induce rebound effects which shift households’ demand curve and distort the net effects of solar PV investments. By analyzing high frequency data on household electricity consumption and production, we document solar PV rebound effect of 7.7 percent, a result that is robust to different sample and model specifications. We also find that households shift their consumption to the time periods when solar electricity production is higher. The solar PV rebound effect shows heterogeneity across time and production level, with higher rebound effects during seasons characterized by higher solar irradiance.

家庭出于不同的原因采用太阳能电池板，但通常是为了减少电费。然而，以接近零的边际成本获得太阳能很可能会引发反弹效应，从而改变家庭的需求曲线并扭曲太阳能光伏投资的净效应。通过分析家庭用电量和生产的高频数据，我们记录了 7.7% 的太阳能光伏反弹效应，该结果对不同的样本和模型规格具有稳健性。我们还发现，家庭将消费转移到太阳能发电量较高的时间段。太阳能光伏反弹效应显示出跨时间和生产水平的异质性，在太阳辐照度较高的季节具有较高的反弹效应。
