Can I charge my electric car with solar panels?

Advancing in all possible directions towards the improvement of new generation cars, the electric car looks to photovoltaic panels to charge safely, correctly and efficiently. Some plates, the solar ones, which can be seen as the great attention for the present and future of these vehicles.

Yes; we can recharge our electric with these plates

Can I charge my electric car with solar panels

Perhaps solar panels are one of the best investments to ensure that the electricity bill is reduced to the maximum at the end of the month. Thus, it should not be surprising that self-consumption with solar panels is on the rise .

Bearing in mind that the cost of charging an electric car is considerably less than refueling a combustion car and that if we charge it at home using renewable energy from the king of stars, the bill can be reduced even more.

And it is clear that within the process of decarbonisation and energy transition, mobility is a fundamental element. And, in this sense, the electric car is establishing itself as one of the main technologies that will contribute to this process. Here, with regard to charging the electric car using photovoltaic panels, we will say that it is possible, but also that everything depends on where the owner of the vehicle lives, what type of car he has and how he wants to use it .

Solar energy as self-consumption

As you know, the energy of the sun is, perhaps, the only one that we can obtain through our own means. That is why the photovoltaic installation has been increasing in recent years and a good percentage of the world has already accessed it.

Perhaps, the photovoltaic solar panel is one of the best investments to ensure that our electricity bill at the end of the month is lower in cost. That is why, if we think about buying a zero emission car and we have solar panels, some questions may arise. The first is: is it possible? And the answer is yes.

The particularity of charging through a photovoltaic system is that you can save practically the entire electricity bill . It is the most efficient option to charge an electric vehicle in a sustainable way.

However, to charge your electric car with the solar energy produced by your solar panels, you will first need a photovoltaic installation, made up of solar panels. Next, you must install a charging point and connect it to your electrical installation. Thus, the charging point will allow you to charge your electric car using solar energy produced by your solar panels or the electricity produced by the network. The greater your energy production, the greater the self-consumption of solar energy , and thus the electricity injected into your electric car will be much more ecological and economical.

Depends on the panel installation chosen

At the same time, the important thing here is to size your installation well , so that you do not lack energy and you can get the most out of it. Let’s take as an example a car that consumes 18kWh per 100km. If you drive an average of 50km per day, your consumption will be 9kWh per day; to which you will have to add the rest of your electrical consumption.

According to this calculation, with a 5kWp domestic solar installation, for example, (which produces about 30kWh per day) it could be enough to cover your energy needs. If that space is available to capture solar energy on the roof of the house, the self-consumption models allow the vehicle to be recharged during daylight hours in combination with the rest of the uses of the house.

In the event that recharging is to be carried out at night, today, as the home storage model is not very well established, the energy marketing market has established tariff models that adapt to this circumstance, allowing a cost very competitive power purchase.

This is when, depending on the installation of solar panels that is chosen, we will distinguish two types :

  • Isolated installation. It is completely disconnected from the electrical network. It works by accumulating solar energy in batteries and is normally associated with a slower recharging process. Any user can install an isolated system on their plot.
  • Self -consumption installation. It is connected to the electrical network. It allows us to supply our recharging point with the electricity necessary to recharge the vehicle. This supply is done in real time and the energy will depend on the photovoltaic capacities of the self-consumption installation. Any excess energy that may exist after recharging the vehicle is transmitted to the home’s electrical network, which means savings in electrical energy both in economic costs and at an environmental level.
