Charging Your Electric Vehicle with Solar Panels: Everything You Need to Know
Can Solar Panels Really Charge an Electric Car?
Yes, solar panels can charge electric vehicles, but the practicality largely depends on your charging habits and the design of your system. Typically, most homeowners won't achieve a full charge from solar alone due to a mismatch in timing. Solar panels generate power during the day when most EVs are in use, leading to inefficiencies in harnessing solar energy for nighttime charges (Solar Energy UK, 2023).
To power an EV exclusively through solar panels, an installation of 8-12 panels is generally adequate, based on estimations by Octopus Energy (2023). However, if the solar array is also supplying household energy, the amount available for EV charging diminishes. The number of panels needed varies based on local climate conditions, the efficiency of the panels, and the battery size of the EV.
How Many Solar Panels Do You Need to Charge an EV?
Charging Duration with Solar Panels: What to Expect
Charging an EV with solar energy can take anywhere from 30 minutes to 12 hours, depending on battery capacity and charger speed. Most home chargers range up to 7 kW, which affects the charging time (Electric Vehicle Association, 2023). The larger the EV battery, the longer the recharge time will be, especially without a robust solar battery to store energy from the day.
Costs Involved in Solar EV Charging
Investing in solar panels for EV charging can be significant, with costs averaging around £7,860 for 10 panels. This outlay covers common needs for both home and EV charging (UK Solar Initiative, 2023). Though initial costs can be steep, many homeowners experience considerable savings over time, as solar energy helps reduce grid reliance.
