Electric vehicles (EVs) are becoming a more familiar sight on the roads these days. As EVs become an increasingly popular choice for consumers, it’s no wonder that there could be a correlation between consumers interested in buying an EV and homeowners looking into a solar panel system for their homes. Both promote renewable energy use and help their users lead a more sustainable lifestyle. 

You might be concerned that solar panels will be unable to handle charging your electric vehicle, though. Let’s answer some frequently asked questions about solar panels and EVs. 

Can You Charge EVs With Solar Panels? 

Let’s answer this basic question: Yes! However, there are a few extra ingredients needed to set your solar-powered home up to properly charge your vehicle. Though most EVs come equipped with a 120-volt cable that can plug into most wall outlets, they charge at an extremely slow rate. Do this only if you’re in a pinch or can afford to let your car charge overnight.

Instead, you’ll need to upgrade to a home charging station. This allows you to charge your EV at a much higher rate of speed, getting you back on the road quicker. Not only that, but there are different models available that may allow for scheduling charges in advance. Combine this with the renewable energy capabilities of solar panels, and you’ve got a quick-charging, sustainable setup! 

How Does The Charging Work? 

Solar panels generate direct current electricity (DC), which is not compatible with the energy used in your home. That’s why the energy flows to the solar inverter where it is converted to alternating current (AC), the standard energy used throughout your home. AC energy is also what your vehicle uses for charging purposes. This AC energy can flow from the solar inverter to your home charging station, where your vehicle can use it to recharge via the charging port. 

How Many Solar Panels Would Be Needed To Charge An EV?

This can depend on a few factors. Your EV’s charge capacity and how much energy your solar panels can process are the biggest factors here. Your solar panels’ production levels can depend on your location, how much shade your roof receives and how much energy your home is using. Each of these will play a role in how long it would take for your solar electricity to charge your EV. 

Remember, your EV doesn’t have to be exclusively charged by solar panels. You can draw energy from the grid to cover any energy shortfalls at any time, including during the night, when your solar panels can’t produce any energy.
