Electric cars are a natural progression in technological advancement and making it work on electricity and endeavouring to charge the car’s battery is the need of the hour that must be looked into. Over the past two years, the purchase of electric vehicles or EVs has increased manifold. According to experts, EVs will become at least 30% of cars bought from the market by 2030. The report published in 2020 under the name if EV30@30 reinstates the fact that global car passenger stock will increase by 30% by the year 2030. This target requires annual growth of 36% between 2019 and 2030. For the cars to keep functioning properly, a solar electric car charger must be set up at homes. 

These chargers are sustainable sources of electric power and come under the strategies to continue to help in the rise of EV production and maintenance. There are homeowners who would really like to switch to an electric car to reduce carbon footprint and they have to be serious about installing a system with the facility of the solar electric car charger. If they have this system, they will always possess a sustainable fuel source for their car needs. Only with the use of sunshine on your roof, you will be able to generate energy that will charge your car batteries to function for hours. Not only is it feasible it saves money as well. In the next section, we will discuss it in detail. 

1. How Power is used by Electric cars?

The amount of power consumed by your electric car depends on a number of factors. They are:

  • The type of EV you are using
  • Kilometres you drive on a regular basis
  • The battery you added to your existing solar panel system on the rooftop

The EPA has an interesting and different rating system for electric cars which do not run-on gasoline. They rate the EVs on the number of kilowatt-hours the car consumes to drive 100 miles. The newest trendsetter the Tesla Model 3 Long Range released in 2020 requires only 26 kWh to go to a distance of 100 miles. There are other cars that consume around 30kWh for driving 100 miles. It depends on the capacity of the vehicle. This consumption is noted and converted by the EPA into a kind of rating known as the “miles-per-gallon-equivalent” or MPGe system. The introduction of this new system helps car owners to determine the most energy-efficient vehicle in the market. 

2. The Number of Solar Panels Required for Charging

The number of solar panels you will require to charge the vehicle actually depends on how much you drive regularly. In fact, the miles must be counted for every day, week, and month. If you need to drive around 100 miles to go to work and come back, you will need many solar panels to garner that much energy while if you live in a densely populated area, you will require less panels because there is not much room to drive around. It is best to calculate the daily consumption to get to the bigger picture. Once, you get to the bigger picture you will know where to fix your solar electric car charger. 

Now, if we assume that your solar panel receives around 5 hours of direct sunlight, a good quality panel should produce around 1.5kwh of energy per day. Thus, you will require at least four 290-watt solar panels to provide the kind of power you need to run your EV. It is a simple calculation; the more you use the car, the more you need to charge. 

3. Equipment Required to Charge an EV

Know that the number of solar panels needed on your rooftop is added to your home’s consumption requirements. So, if you are really looking for benefits like zero carbon footprint, you will require a bigger solar panel arrangement on the roof. Besides charging the car from the solar panel rooftop grid, you will also require a battery for storing surplus energy that can be used later on as backup. This is vital because many families prefer charging their cars during the night when there is no sun to produce instant energy thus using battery storage. Just do a little research on the batteries available in the market compatible with car charging. You should lay your hands on one of them. 

4. Charging Station

You may actually draw the power from the solar grid on your rooftop, but you will require a charging station with a solar electric car charger to get the job done. The charging station is usually located in the driveway or the garage for obvious reasons. You just plug the point properly to charge your EV. Level 2 chargers do the job in much less time than the other varieties. Some of the best chargers in the market offer up to 37 miles for each hour of charging. This smart charger is also compatible with a Wi-Fi connection thus sending a message to your smartphone regarding the time left to complete a full charge. It actually makes your work easy. 

The Green EV Revolution With the enhanced need for a clean environment, the demand for electric cars is increasing and so also the demand for solar-powered vehicles. This increasing demand is transforming the automobile industry. By the time we reach 2030, we will witness the green EV revolution changing lives. We might be able to look into a future where we charge our vehicles on the go with solar panels fitted on our car roofs to make them even more accessible. But until that time, we have to suffice with solar electric car charger doing its job. Very soon all makes, and models will have a system to solar charge the vehicles.
