With the growing environmental awareness and advances in sustainable technologies, more and more people are choosing to charge their electric car using solar panels. This combination not only maximizes the benefits of electric mobility, also allows for the use of a clean and renewable energy source.

In this article, we explain how a photovoltaic system can provide the energy needed for your vehicle, helping you reduce costs, decrease your dependence on the electrical grid, and actively contribute to sustainability.

Charging an electric car with solar panels

More and more people are choosing electric cars as an eco-friendly and economical alternative to traditional vehicles. However, charging an electric car with solar panels is the key to maximizing environmental benefits and further reducing energy costs. In this article, we will explain how installing solar panels in your home or business can offer a clean and renewable energy source for your vehicle, contributing to a greener and more efficient future, and how your electric car charger installation can benefit from this renewable energy.

How is a car charged with solar panels?

Charging an electric car with solar panels is an efficient and sustainable option that utilizes renewable energy. The process begins with installing a photovoltaic system at your home or business, which converts sunlight into electricity using the photovoltaic effect.

One of the most common questions is: Can you charge an electric car with solar panels? The answer is yes. The energy generated can be used directly to charge the vehicle through a charging point connected to the electrical grid. Additionally, if you have storage batteries, it is possible to charge the car even when there is no sunlight, such as at night or on cloudy days.

Using solar panels to charge an electric car offers significant savings in the long run, as an adequate system can cover much of the vehicle’s energy needs, reducing dependence on the electrical grid and charging costs. In addition to being an economical option, it also contributes to reducing the carbon footprint. Installing a solar panel system is an excellent way to maximize the benefits of electric mobility by harnessing a clean and abundant energy source like the sun.

How long will it take to charge the car with solar panels?

El tiempo de carga de un coche eléctrico utilizando placas solares depende de varios factores clave, como la capacidad del sistema fotovoltaico, el tamaño de la batería del vehículo y las condiciones solares del lugar donde te encuentres. Además, la calidad de la instalación del cargador de coche eléctrico es fundamental para garantizar una carga eficiente y rápida. Aquí te explicamos los principales factores para tener en cuenta:

• Solar system capacity: The more solar panels you install and the more efficient they are, the more energy they will generate and the faster you will be able to charge your electric car.
• Car battery size: Electric cars with larger batteries will require more time for a full charge. The duration can vary between 8 and 12 hours under optimal solar generation conditions.
• Solar irradiation conditions: The amount of sunlight available will depend on your location and the time of year. On sunny days, the charge will be faster, while on cloudy days it may take longer.
• Household energy demand: If your house is using a lot of energy while the car is charging, this could slow down the process, as the electricity generated by the panels will be shared between various devices.
• Storage system: If you have storage batteries, you can accumulate energy during the day to charge the car at night, optimizing the charging time.

How many panels do I need to charge the car?

The number of solar panels needed to charge an electric car primarily depends on the vehicle’s battery capacity and the power of the installed panels. Below are the key factors that influence this estimate:

• Electric car battery capacity: Electric cars have batteries of different sizes, typically ranging from 40 kWh to 100 kWh. The larger the battery capacity, the more energy you will need to generate for a full charge.
• Solar panel power: Each solar panel has a nominal power, measured in watts (W). For example, a standard panel can generate between 300 and 400 W of power under optimal conditions. To estimate how many panels you need, divide the car’s battery capacity by the total power generated by the panels per day.
• Available sunshine hours: The amount of energy your solar panels can generate also depends on the solar irradiation in your area. In places with more hours of sunlight per day, you will need fewer panels to reach the energy required to charge your car.

Advantages of charging the electric car with solar panels

Charging an electric car with solar panels is not only an eco-friendly option but also offers numerous advantages both economically and in terms of sustainability. Here are the main benefits:

• Energy cost savings: By generating your own electricity from the sun, you reduce or eliminate reliance on the electrical grid, which leads to significant savings on energy bills. In the long run, the investment in solar panels and a charger can pay off quickly, especially considering the rising cost of electricity.
• Energy independence: By installing a photovoltaic system, you can generate your own energy and become less dependent on fluctuations in the grid’s pricing. Additionally, if you combine solar panels with storage batteries, you can use the energy generated during the day to charge your car at night, maximizing your energy autonomy.
• Taking advantage of subsidies: Many countries have incentive programs that facilitate the installation of charging systems and solar panels. For example, electric car charger subsidies and support for solar panel installation can significantly reduce the initial cost of these systems, making them more accessible for homes and businesses.

The company Emovili, a specialist in the installation of charging points and solar panels, as a partner of Solum, offers integrated solutions that optimize the solar energy charging process, providing users with efficient and cost-effective access to this technology.
