Household photovoltaic energy storage and electricity complementarity

Is Q-complementarity hypothesis correlated with demand for photovoltaic EVs?

Findings show correlated demands in support of q-complementarity hypothesis. Photovoltaic (PV) units and electric vehicles (EVs) are two household goods that are the focus of much research, and many policy initiatives attempting to promote a more sustainable, low-carbon energy system.

Can residential-level photovoltaic power generation and energy storage be integrated into smart grid?

Abstract: Integration of residential-level photovoltaic (PV) power generation and energy storage systems into the smart grid will provide a better way of utilizing renewable power.

Are PV and EV technologies Q-complements in household utility?

Specifically, we posit that PV and EV technologies may be q-complements in household utility, as defined in Eq. (1), such that the welfare gain (benefits) from adopting one of these technologies is increased if the other technology is also owned/adopted. This condition could also hold between other electricity-intensive appliances and PV.

Are PV installations and electricity-intensive home appliances Q-complements in household utility?

In this work, we explore the hypothesis that PV installations and electricity-intensive home appliances are q-complements in household utility. If correct, this would mean that the adoption of PV increases the utility experienced by owning or purchasing an electricity-intensive appliance.

Could a PV-owning household be a Q-complement?

We posit the goods could be q-complements due to a PV-owning household's ability to offset and shift their electricity load from EV charging to increase the self-consumption of ‘home-made’ electricity, thereby increasing the positive feelings of environmental efficacy and monetary returns from the PV unit.

Are household items Q-complements with PV systems?

These results suggest that households with big ticket, electricity-intensive items are more likely to adopt PV, even after controlling for income effects, and vice-versa, suggesting these items may be q-complements with PV systems as they give the potential for higher self-consumption and loadshifting to times of higher PV production.
