Getting electricity with solar panels (photovoltaic panels) - You want to use some of the electricity and sell the surplus

Verified 01 octobre 2025 - Directorate of Legal and Administrative Information (Prime Minister)

Your situation

  • You want to generate electricity for your personal use and sell what you don't consume
Edit

These are the following equipment:

  • Solar panels. These panels capture solar energy to turn it into electricity. They can be attached to your original roof (non-integrated equipment) or integrated as a replacement for the original roof (built-in equipment).
  • One or more inverters. The inverter is a small housing fixed on a wall as close as possible to the solar panels. It makes it possible to convert the direct current obtained into alternating current identical to that of the public electricity network.
  • Batteries to store the electricity obtained for your consumption.

Yes. You have to make a prior declaration of works to your town hall.

If you are building a house, the installation of solar panels must be included on your application for building permit.

Warning  

Before making your declaration or application for a building permit, it is recommended to contact your town hall. They can inform you about any local restrictions regarding the installation of solar panels or specific aesthetic requirements such as the color of the roof.

Who shall I contact

It is recommended to use a recognized environmental guarantor (EGR).

For the list of RGE professionals, you can use an official directory:

Search for a recognized environmental guarantor (EGR) or architect

Before signing a quote with a professional, it is advisable to evaluate the profitability of the project using a simulator:

Purchase and installation

The price of equipment (solar panels, inverter, ...) and their installation is variable. It depends on the following:

  • Materials used
  • Installation method (integrated or simply installed solar panels)
  • Choice of the professional who will settle your solar panels.

Since 1er October 2025, you benefit from the value added tax (VAT) at 5.5% (against 10% before that date) if the following conditions are met:

  • The power of the installation is less than or equal to 9 peak kilowatts (kWp). This corresponds to about 25 solar panels.
  • The panels have a low carbon footprint (less than 530 kgCO2eq/kWc) 
  • Heavy metal content is zero or low: silver (less than 14 mg/W), lead (less than 0.1%) and cadmium (less than 0.01%)
  • The installation incorporates an energy management system (EMS) that synchronizes consumption with solar production (heating, hot water, charging station, ...).

If the conditions are not met, then you are subject to the VAT rate at 10%.

Operation

The sale of surplus electricity results in the annual payment of a tax called transmission rates for electricity producers.

Once the solar panels are settled, you have the obligation to take out civil liability insurance for your installation. For this, you can request the modification of your home insurance policy. Your contribution amount will then be recalculated.

FYI  

The lifetime of solar panels is usually 25 to 30 years. You should regularly maintain your solar panels (clean them), as their materials degrade with the weather and pollution. In addition, the inverter must be changed approximately every 10 years.

Yes. You can benefit from the investment premium also called self-consumption premium for the sale of surplus electricity generated.

Warning  

For this, your solar panels must have been settled by an RGE installer.

The amount of the premium depends on the power of your installation. This amount is changed quarterly.

This bonus is accessible without resource requirements. No specific steps are required, except that of connecting your installation to the public electricity grid.

To be able to sell unused electricity, you must make a connection request to the public electricity system operator, i.e. Enedis :

Enedis: apply for connection to the public electricity grid

This service is paid for and its cost varies according to the characteristics of your installation.

Please note

The connection request can be made by yourself or by the installer of your solar panels.

Enedis addresses you a connection proposal (RDP) and a number of Network Access and Operating Agreement (NEA). Once the RDP has been accepted and the CAE has been signed, Enedis will connect and commission your facility.

Enedis settles 2 communicating meters in your home:

  • 1 production counter which measures all the electricity produced by your solar panels and which is used to calculate what you sell
  • 1 consumption counter (usually Linky) to track your consumption from the network and, to allow Enedis to manage the entire connection.

When you request a connection, you sign a purchase obligation contract (COA) with Enedis. This contract requires Enedis to purchase your surplus electricity.

The duration of the contract is 20 years. It applies from the date of commissioning of your equipment (actual connection to the network).

The purchase price of the electricity produced is set by law and therefore cannot be negotiated.

The rate that applies to your contract is the one in effect on the date of the request to connect your equipment.

Each year, on the renewal date of your contract, you must send your invoice to Enedis.

No, you do not have to pay income tax for the sale of electricity if you meet the following 3 conditions:

  • The electricity produced has a power of 3 kWp or less
  • Your equipment is connected to the public network in 2 points at most
  • The electricity produced is not used for the exercise of a professional activity.

However, if one of the 3 conditions is not met, you must pay income tax. Income from the sale of electricity must be included on your tax return as Industrial and Commercial Benefits (BIC).
