- EVs with V2H tech reduce household electricity costs and decrease need for large home battery systems.
- Most efficient setup: 7-kW solar + 9-kW battery + EV with V2H yields lowest annual cost of $2451.
- V2H enables using EV-stored energy during peak-demand periods, cutting grid imports by 78%.
- Removing V2H requires larger 13-kWh battery, increasing annual electricity costs by 10.8%.
- V2H can reduce need for dedicated home battery storage and lower household electricity costs by 6.8%.
- V2H improves solar self-consumption, reduces grid reliance, especially in winter when solar output is lower.
- With rising EV adoption, V2H could become mainstream for managing energy costs.
