Investment Bonuses for Self-Consumption
The State encourages the installation of solar panels by offering a bonus adjusted according to the capacity of the installation. However, it is subject to strict criteria, reserving its allocation to eligible households.
Who can benefit from the self-consumption bonus, and what are the eligibility requirements?
The self-consumption bonus is conditioned by photovoltaic self-consumption and the sale of surplus, which is mandatory for designated buyers, with rates revised quarterly. Opt for solar panels on your roof with overlay installation, requiring the intervention of a certified professional and a power limited to 100 kWc. Ground-mounted panels are not eligible.
What is the amount of the bonus awarded for self-consumption?
The photovoltaic self-consumption bonus depends on the size of your installation and varies each quarter. It is determined by four categories based on the peak power of the installations:
- Less than 3 kWc
- Between 3 and 9 kWc
- Between 9 and 36 kWc
- And Between 36 et 100 kWc (the limit not to exceed to remain eligible for the self-consumption bonus).
In summary: a more powerful installation translates into a lower bonus, hence the importance of optimizing your self-consumption.
Below are the bonus rates for installations (from 1 November 2024 to 31 January 2025):
- 220 € per kWc for installations under 3 kWc ;
- 160 € per kWc for installations between 3 and 9 kWc ;
- 190 € per kWc for installations between 9 and 36 kWc ;
- 100 € per kWc for installations between 36 and 100 kWc ;
To estimate your bonus, multiply the rates by your installation's capacity. For example, a 7 kWc installation would be eligible for €1,540 (€220 x 7 kWc).
The Energy Regulation Commission adjusts the self-consumption bonus quarterly based on the number of new requests for connection to the distribution network, such as Enedis. The current rates are accessible here
What steps must be taken to access this bonus?
The self-consumption bonus request is automatically activated after your photovoltaic installation is connected. Once validated, the amount remains fixed despite quarterly rate variations.
When is the bonus paid?
The bonus is paid by a designated buyer one year after commissioning, along with the income from surplus sales, except for installations over 9 kWc, which receive 80% immediately and the rest over four years.

Remuneration for Surplus Sale
Owners of self-consumption solar installations with surplus sales provide green electricity to neighboring households by selling the excess to designated buyers like EDF OA. Enedis covers the connection costs, thereby encouraging the energy transition to renewable energy.
What amount is granted for the purchase of excess electricity?
The purchase amount for surplus electricity depends on the installed capacity and fluctuates quarterly, defined according to four categories based on the peak power of the installations.
Below are the rates (from 1 November 2024 to 31 January 2025) as follows:
- 0,1269 € per kWc for installations of less than 3 kWc ;
- 0,1269 € per kWc for installations between 3 and 9 kWc ;
- 0,0761 € per kWc for installations between 9 and 36 kWc ;
- 0,0761 € per kWc for installations between 36 and 100 kWc ;
Once the contract is established, this rate remains constant for a period of 20 years, covering the entire duration of the agreement.
Who can benefit from the surplus sale remuneration?
To benefit from self-consumption with surplus sales, the solar panels must be installed on a roof and connected to the electrical grid to inject the surplus. Isolated sites are not eligible. The excess electricity produced is sold to a designated buyer in the absence of storage
What administrative steps need to be taken?
The application for the self-consumption bonus is activated automatically after your photovoltaic installation is connected. Once validated, the amount remains fixed despite the quarterly tariff variations.
-
Make an initial work declaration to the town hall.
-
Seek the services of an expert for the installation of solar panels.
-
Submit a connection request to the relevant authorities.
-
Establish a contract with a mandatory buyer.
When and how to invoice the surplus sale?
For invoicing the surplus electricity, the process is quick and simple: once a year, on the anniversary date of the contract's start, take a meter reading.
