Based on this, charging an electric vehicle typically will require 7 to 12 solar panels out of however many you install on your home overall. What are the benefits of charging an electric car with solar panels?
According to Octopus Energy, a solar panel system with around 8–12 panels will usually be able to power an electric vehicle. But that’s if you’re using the solar panels solely to charge your car, and not to power your house.
Charging electric cars with solar power is quite simple. It works by the panels soaking up sunlight and turning it into electricity. This electricity, which is called direct current (DC), then goes through a device called an inverter, which changes it into a type of electricity that can charge the car's battery, called alternating current (AC).
Solar panels are rarely used to fully power an EV, but they can top up its charge After paying the installation costs of an electric charger, you’re also faced with the price of the electricity to charge your car. You can reduce this with solar panels, leaving you with a smaller carbon footprint and more money in the bank.
Charging your car with solar panels will benefit your wallet today and save you money in the long run. And when it comes to selling your property, having an EV charger could actually make you money.
If your house already has solar panels fitted, then all you’ll need is a domestic solar photovoltaic system (solar PV) and the solar charger cable for electric car’s battery.
