Is It Possible With Solar Panels to Charge an Electric Vehicle at Home?
It would be the most cost-effective combination. It is possible to use the electricity generated by solar panels for charging an electric car.
It’s a perfect combination. Peugeot has explained how you can charge your car using solar energy generated from solar panels.
Truth is that electricity consumption has tripled by 2020. In fact, currently 113.24 million watts of electricity is generated in the residential segment using solar panels. There are currently two types photovoltaic installations.
Isolated: This is the one that operates independently from the electrical network. It collects solar energy from the plates and stores it in its batteries. It is therefore difficult to charge an electric car throughout the year, as the batteries can run out if there are cloudy days.
Self-consumption : In this instance, the photovoltaic plant is connected to the electric grid. Without compensation or surplus, residential use is not possible. This allows the home to generate its own energy either from its solar panels, or from the electricity network. If we have surplus energy, it is inducted into the electricity grid. This will result in a reduction of your electricity bill. The compensation price is set by the marketing company and is currently USD 0.059/kWh plus VAT.
It is possible to also install a dynamic control in a connected installation. This allows you to regulate the power from the solar panels as well as the energy from the contracted networks while charging your car. This would allow you to either charge your vehicle with only the solar energy surplus or combine them for a faster charge.
Solar Energy for Electric Car
You should know how many panels are required and how much power is needed. It depends on how much power is used in the vehicle and at home. It is usually between 13.2 kWh (for example, a Peugeot3008 Hybrid), to 50 kWh (for a 100% electrical car like an e208).
The energy that a solar panel can produce is typically between 150 and 500 W, but it will vary depending on where it is located.
Also, a solar panel system does not produce energy at night so it is best to charge your car during the day when you have full plates. It would then be possible to charge an electrical vehicle using solar energy.
A practical case
Let’s take for example, a Peugeot E-208 with a range of 340 km (WLTP), and a 50 kWh battery. If we drive 15,000km per year, then we will use 2,205 kWh annually. We would need five solar panels that can produce 450 kWh annually to achieve this.
Peugeot claims that the excess energy from our installation, which is connected to the network, would be economically offset by the less-powerful contribution received at night and winter.
