Addressing EV charging costs with solar power

Researchers from the University of South Australia (UniSA) have discovered that households with solar panels and batteries have an advantage when it comes to saving money on EVs. It has been calculated that EV owners can reduce annual electricity costs by nearly 40% if households are not fully reliant on the grid. As EV uptake rapidly increases, it is estimated that by 2030, there will be 145 million EVs on the road, a stark contrast to the 11 million today. Global EV sales have continued to rise in 2022 after a record-breaking year, but efforts to remove the barriers facing EV uptake are needed to ensure future growth. The researchers used data from South Australia, where over 40% of homes have rooftop solar panels, to compare several household scenarios. Within this, they considered EV charging demand, PV solar panel installation cost, battery degradation, and export power limits. “When solar panels are added, about 20% less energy is impod and with batteries, this is reduced by around 83%. When electric vehicles are added, consumed energy rises significantly but impod energy can be reduced by around 89% of total consumption.
