On June 1, 2019, the EDF regulated rate increased by 5.9%. From 2003 to 2019, the increase is even 39%! It is not surprising to see that the electric car -it has been increasing lately.
- The figures are eloquent: more and more French families choose the car -electric content with a photovoltaic installation. Lower installation price, network independence, term savings … there are many advantages.
- If you choose the car -electricity, increase the profitability of your photovoltaic investment by selling the self -producing electricity surplus.
- With the car -electric, it is always possible to look for more savings. By synchronizing the production of sun electricity and home consumption optimizes the profitability of your installation. To promote this synchronization, you can develop your habits, think about domestic automation and consider solar batteries!
Produce and consume your electricity
How does it work?
The photovoltaic effect is to transform the sun’s rays into electricity.
Concretely:
You have solar panels on the house roof or an attachment.
The cells of the solar panel capture the sun’s rays and transform them into continuous electricity.
The continuous electric current is converted into alternating current by an inverter, a small device placed in a room of your choice.
The alternative electric current is therefore used in 2 ways: to feed your home with electricity or by injecting electricity not consumed in the public network (sell your production).
Savings on invoices and additional income
- By choosing the car -electricity, remain connected to the public distribution network. When your production is not enough to cover your needs, the usual electricity supplier takes over.
- You can combine the savings on your electrical invoices (cars -consum) and photovoltaic income invoices (selling the part of your production that is not consumed). We are talking about cars -with the sale of the surplus. EDF has the obligation to buy electricity, at fixed and guaranteed prices for over 20 years.
- When installing solar batteries to increase autonomy, the priority order for the use of electrical production is as follows:
Solar electricity is used to provide your home.
The excess is stored in the battery.
The surplus of photovoltaic electricity, when the battery is full, is injected on the net.
Note: Your solar panels produce even more because the sun shines. In these conditions, your production will be greater than your electrical needs during a strong sun period! It is during these periods that the surplus is injected into the network or stored in a possible battery for subsequent use.
- Choose between cars – electric content – with or without surplus resale – and total sale before installing your solar panels:
Because the installation methods differ according to your goals.
To correctly calculate the profitability of the photovoltaic investment.
To make sure to meet the conditions of admissibility to the state financial help – car premiums -consum.
Advantages and disadvantages of the car -Consummer
A phenomenon that rises to power in France!
The solar revolution is in progress and the mania for the car -electric content is gaining more and more houses! Test:
Au 3th Fourth 2017, there are 2,418 photovoltaic installations in complete sales, against 2,044 excess sales structures.
Au 2th Fourth 2018, the trend of course reverses: 1,457 French families are equipped with solar panels for total sale. At the same time, 4,131 connection requests for excess sales are listed!

The advantages of consuming one’s electricity
But why do we now choose electrical self -consciousness? Here are the topics:
Advantages of the car -electricity | |
Economic arguments |
In the consumption of cars, benefited from an investment bonus. |
A gesture for the planet | The consumption of its solar electricity is to ensure that your home with renewable origin guaranteed is powered. |
A feeling of independence |
|
An exponential promise of profitability | While the purchase rate of photovoltaic electricity is constantly falling, the price per kWh provided by the distributors increases regularly. Saving over 25 years the price has increased by KWh, bet on an exponential profitability*! |
*Illustration:
- For sale total, a constant income is generated for the entire operational time of your solar panels. For example: for 5,000 kWh sold in the EDF solar purchase obligation, earnings € 788 every year.
- In the consumption of cars, save every kwh consumed on electricity bills. Save even more because the KWh price increases! For example: consuming 5,000 kWh, you save € 750 at the price of KWH in 2018 – chosen value of € 0.15. If the price for KWH increases, for example 10 % in 3 years – € 0.165 for KWh in 2021 – save € 825!
Sell the excess product to earn more!
We told you above, you can choose the car -electricity while selling the excess of your production. This is undoubtedly the most judicious choice. During a day, the production is sometimes higher than your electrical needs of the moment. What to do with the surplus? You have 2 possibilities:
Injects electricity on the network and sell it to EDF or to another authorized buyer.
Keep your production surplus in sudden batteries to use it later for your consumption. When sunscreen are not enough to meet your needs (at night, for example), the batteries take over!
The sale of the surplus is very economically advantageous. Photovoltaic income allows you to compensate for electricity purchase invoices from the lowest sunny periods. In addition, you receive a state bonus paid in 5 years!
Car -conso to obtain independence
It is completely disconnecting from the electricity grid, is it utopian? Some testimonies show that not, provided to adapt your daily behavior and equip the necessary materials.
Car -daily electric content
If you invest in a photovoltaic installation, you can produce the volume of electricity in 1 year necessary to cover your energy needs. But be careful, the moments in which you need electricity do not coincide exactly with the moments when your solar panels produce them. I wait:

As part of a typical day:
- You get up at 7 in the morning, take your phone that was recharging. Turn on the lights and take a hot shower, thanks to the electric water heater. So prepare a coffee while listen to the radio. As soon as you get up, consumption electricity while the morning sun only starts to feed your solar panels.
- Around 13:00, the sun is at its Zenit: your photovoltaic panels produce a lot of electricity. If you work, you’re not at home! Solar production cannot be completely consumed.
- 19:00, the day ends and go home. Make your machines (washing machine, dryer, etc.), you need lighting, watch TV and prepare dinner. All these daily gestures are voracious in electricity. The sunset and photovoltaic panels no longer produce.
That’s why, the sale of excess electricity allows you to create the car on the car -photovoltaic electrical substitute! The income generated by the day will compensate for the purchase of the electricity you need at night.
And with a calendar battery?
The solar battery is a great way to obtain energy autonomy: increase V
Our rate of car -consum. In fact, all the photovoltaic electricity produced during the days of the day is not necessary for it to be stored. It is then returned when you consume, intelligent, right?

But be careful: the price of solar batteries is not negligible. It is necessary to integrate it in the calculation of profitability.
Suitable your behavior: make production and consumption coincide!
To increase your car rate -Know the electricity consumption of your home, there are simple and … free means!
Some tracks:
- Program your machine washing machine and the dishwasher in particular the day, at the Pic du Soleil.
- Reduce electricity consumption in the evening without sacrificing its comfort: Avoid loading your electronic devices prematurely, use low consumption bulbs, promote higher energy class appliances – A+…
To synchronize photovoltaic production and the electric car – the intelligent management and management systems of your consumption – domestic automation – are very useful.
