Does installing photovoltaic panels affect daily electricity usage patterns? A generalized additive model approach

• We study how households with photovoltaic panels consume electricity. do this via a longitudinal dataset on 700 households. find that there are differences in electricity patterns between and without panels. still much can be gained by shifting the consumption of Installing (PV) household rooftops significantly contribute to mitigating anthropogenic climate change. The mitigation potential will higher when would use PVs sustainable way, is, if they match their demand production, as avoid using from grid. Whilst some have argued owning motivate PV others does not result load shifting, or owners may even more energy production is low. This paper addresses critical issue, examining what extent likely shift reduce Extending previous studies, we analyse actual high frequency grid smart meter data PVs. Specifically, employ generalized additive models examine whether hourly net (i.e., difference consumed supplied back grid) only lower during times high, but also low, compared Results indicate negative, suggesting sent excess power However, found no suggests installing promote use, installment enhanced encouraging use.
