How Many Solar Panels are needed to Charge an Electric Car?

Electric cars with solar panels bring about an unpopular question of how many solar panels are needed to charge an electric car. Now, the number of solar panels needed will vary according to the size of the car. If we consider the standard Tesla Model S, we will notice that the battery capacity of this car is 100kWh.

The solar panels' size also affects the number needed to charge an electric car, apart from the car's size. Since a low output solar panel can generate 1kWh of AC power each month, you will need at least 75 solar panels to charge a standard Tesla Model.

Is it possible to charge an electric car with solar panels?

In case you have a solar panel installed on the roof of your house, you will know that it cannot store electricity as such. Therefore, whatever electricity is generated using solar panels has to be used immediately.

You can use the generated electricity to power the different appliances in your home or sell it back to the grid. The solar panels to charge cars can be used by storing the power generated in a solar battery. The excess energy can be stored in the solar battery and can later charge your electric car.

However, to charge your electric car using a solar panel, you will have to install a PV inverter as well as a home charging unit. This can be a costly affair but at the same time help you in the long run. The PV inverter will be able to convert the solar energy into DC as required by your car.

You can contact Waaree to get a solar panel installed, which will help you charge your electric car.

Is it possible to charge an electric car?

You can charge your electric car pretty easily, no matter where you are. There are a few steps that you will have to follow to charge your electric car with ease.

Charging at home:

You can easily charge your electric car if a home charging unit is installed. Home is the perfect place to charge your car overnight. You can go through the steps to charge your electric car at home.

  1. Home charging is likely to provide you with the fastest charging speed.

  2. The home charging unit has safety features, and if it is connected to WIFI, you can also download additional smart features.

  3. The charging system will have a cable attached to it. You will have to plug this cable into your electric car.

  4. The system will mostly have "Type2" socket cables that are easy to attach. In case you don't have one, you can easily purchase it from anywhere.

Charging at work:

The battery of your electric car can wear off during work hours. Therefore, charging at work is another convenient way since your car is parked for a longer duration. You can follow the given steps to go about the process.

  1. The charging unit at work is the same as that home and will offer a "type 2" socket. Therefore, you will need your cable to charge your electric car.

  2. The charging method will depend upon the organization where it has been installed. You will have the option to charge using the standard plug-in cable, or you will have to swipe a smart card to charge your electric car, or else you might have to install an app and charge your car using that.

Charging at other places:

You can charge your electric car at public places where the charging units have been installed. These can be scarce but follow the same procedure as the charging units at home or work. It will be easy for you to follow the instructions and charge your electric car.

Is it possible to put a solar panel on an electric car?

Putting a solar panel on an electric vehicle is not a wise choice. Although sticking the solar panel on the roof of your electric vehicle can easily as well as directly charge your car, engineers have been working for many years to develop this technology. The main hurdle is that the size of the solar panels attached at the top of your electric vehicle will not be powerful or efficient.

The size will not be large enough to charge your car fully. Even the cost factor will be an issue since the whole system can be pretty expensive. Therefore, it is always better to get a solar panel installed in your home along with a charging unit and get your electric vehicles charged there themselves.

For installation-related queries, you can always contact Waaree and rely on them to get your work done!

How are many solar energy storage batteries recommended?

Solar energy batteries are needed to store the power generated by solar panels to be used later. The number of solar batteries will depend upon the amount of power generated by the solar panels. This will again depend upon the size of the solar panels installed at your place.

Ideally, four to five solar energy storage batteries are needed to provide power to the whole house and use the power to charge your electric vehicles. However, if you feel that your solar panel generates more power than needs to be stored, you can always purchase more storage batteries.
