- Choosing an RGE certified installer is important to benefit from aid and ensure the quality of the installation.
Sommaire
Toggle1. Self-consumption
Self-consumption is the idea of directly consuming the electricity that your solar panels produce. It’s an increasingly popular approach, especially with the evolution of feed-in tariffs. Basically, instead of sending all your production back to the grid, you use it to power your own home or business. It’s a smart way to reduce your dependence on traditional energy suppliers and to control your costs.
There are several ways to practice self-consumption:
- Total self-consumption: You consume all the electricity produced by your panels. This is ideal if your consumption roughly corresponds to your solar production.
- Self-consumption with sale of surplus: You consume what you need and sell the rest to the grid. This is a good option if your production often exceeds your consumption.
- Self-consumption with storage: You use batteries to store the energy produced during the day and use it in the evening or on cloudy days. This maximises your autonomy.
Self-consumption is a winning strategy to reduce your electricity bill and increase your energy independence. It’s an investment that can be profitable in the long term, especially if you choose the right configuration for your needs.
Self-consumption is an effective way to reduce your electricity bill. Remember to properly size your installation so that it corresponds to your needs. Solar panels offer long-term budgetary visibility.
2. Sale of surplus
Self-consumption with sale of surplus is an interesting option to optimise your solar income. Instead of simply consuming the energy you produce, you can sell the excess to the grid. It’s an effective way to make your photovoltaic installation profitable.
How does it work?
The principle is simple: your solar installation produces electricity. You consume what you need to power your home. The remaining electricity, the one you don’t use immediately, is injected into the electricity grid. You are then paid for this electricity.
The advantages of selling the surplus
- Additional income: Selling the surplus allows you to generate additional income by selling the electricity you don’t consume. It’s a way to amortise your initial investment more quickly.
- Optimisation of the installation: You don’t have to worry about sizing your installation as accurately as possible in relation to your consumption. You can install more panels and sell the surplus.
- Contribution to the energy transition: By injecting your surplus of green electricity into the grid, you contribute to the energy transition and the reduction of greenhouse gas emissions.
The steps to follow
- Connection to the grid: You must have your installation connected to the electricity grid by Enedis.
- Purchase contract: You must take out a purchase contract with EDF Obligation d’Achat (OA) Solaire or another electricity supplier. This contract defines the price at which your surplus will be bought back.
- Monitoring of production: You must monitor your electricity production and the quantity injected into the grid for billing.
Purchase prices
The surplus purchase prices are set by law and vary depending on the power of your installation and the date of signature of the contract. It is important to find out about the current prices before starting.
Selling the surplus is an advantageous solution for most residential photovoltaic installations. It allows you to maximise solar income while contributing to the energy transition. However, it is important to study the purchase prices and the steps to follow to optimise your profitability.
Points of vigilance
- The purchase price: It is important to compare the offers of different suppliers to obtain the best possible purchase price.
- Connection costs: Connection to the grid may incur costs. It is important to take them into account in your profitability calculation.
- Taxation: Income from the sale of the surplus is taxable. It is important to find out about the applicable tax rules.
In conclusion, the sale of surplus is an option to consider seriously if you want to maximise your solar gains. Don’t hesitate to call on an RGE installer to support you in your project and advise you on the best options for your situation.
3. Self-consumption premium

The self-consumption premium is a financial aid paid by the State to encourage individuals to invest in photovoltaic installations and consume their own electricity production. It’s a non-negligible boost to make your solar project more affordable. Basically, the idea is to encourage you to use the energy you produce rather than systematically reselling it.
This premium is degressive depending on the power of your installation. The more powerful your installation, the lower the premium per kilowatt-peak (kWp). It’s a bit confusing at first, but it’s understandable: the State wants to encourage as many people as possible to get started, even with more modest installations.
It is important to note that this premium is subject to certain conditions, including installation by an RGE (Recognised Guarantor of the Environment) certified professional. This is a guarantee of quality and seriousness for your installation.
Here are some important points to remember:
- The premium is paid in several instalments, usually over the first five years of operation of your installation.
- It can be combined with other aid, such as local aid or tax credits (if applicable).
- The amount of the premium is revised regularly, so it is important to keep informed of the latest developments. You can consult Solencia’s prices and premiums for more information.
In summary, the self-consumption premium is a major asset to make your photovoltaic installation profitable. It reduces the initial cost of the investment and accelerates the return on investment. Don’t hesitate to ask your RGE installer for information on how to obtain it and the amounts applicable to your project. The self-consumption premiums are an excellent way to maximise your solar gains. It is important to note that the self-consumption premium, effective until 31 January 2024, varies depending on the photovoltaic power.
4. Purchase obligation
![]()
The Purchase Obligation (OA) is a scheme set up by the State to encourage the development of solar energy in France. It guarantees photovoltaic electricity producers a fixed purchase price for their production for a specified period, usually 20 years. It’s a bit like having a concrete contract with EDF, which is obliged to buy your electricity at a price fixed in advance. Not bad, is it?
This mechanism is particularly interesting if you produce more electricity than you consume, as it allows you to sell the surplus at an advantageous price. It’s a bit like your roof becoming a small power plant that earns you money.
Here are some important points to remember about the Purchase Obligation:
- The purchase price is set by ministerial decree and varies depending on the power of your installation and its date of commissioning. It is therefore important to keep informed of the prices in force. You can consult the EDF OA purchase prices for 2025 to get an idea of current prices.
- The Purchase Obligation contract is concluded with EDF Obligation d’Achat (EDF OA), an EDF subsidiary specially dedicated to this scheme. It is with them that you will sign your contract and invoice your production.
- To benefit from the Purchase Obligation, your installation must meet certain technical and administrative conditions, including being installed by an RGE (Recognised Guarantor of the Environment) certified professional. This is a guarantee of quality and seriousness for your installation.
The Purchase Obligation is a pillar of support for solar energy in France. It offers financial visibility to producers and contributes to the country’s energy transition. It’s a win-win scheme for individuals and for the environment.
Basically, the Purchase Obligation is the guarantee of being able to sell your surplus electricity at a fair price for 20 years. It’s a strong argument for investing in solar, especially if you live in a sunny region. And if you produce more than you consume, you can even earn money! Don’t hesitate to find out about the eligibility conditions and the prices in force to see if it’s an interesting option for you. You can even sell your solar electricity to EDF Obligation d’Achat for a few pence per kWh.
5. Contract with EDF OA
Taking out a contract with EDF Obligation d’Achat (OA) is a decisive step to secure your income from the sale of your solar electricity. This contract binds you to EDF OA for a period of 20 years, ensuring a fixed and guaranteed purchase price for the entire period. It’s a significant peace of mind, especially in an energy market that is sometimes fluctuating.
The contract with EDF OA is therefore a central pillar of the profitability of your photovoltaic installation.
It is important to fully understand the terms of the contract before committing. Here are some points to consider:
- The purchase prices applicable to your installation (they depend on the power of your installation).
- The invoicing and payment procedures.
- The obligations of each party (you and EDF OA).
It is advisable to read the contract carefully and not hesitate to ask EDF OA questions if certain points are not clear. A good understanding of the contract is essential to avoid unpleasant surprises and optimise your solar income.
For those considering the future of photovoltaics perspectives and innovations, understanding these contracts is essential. EDF OA contracts offer financial stability, especially with 20-year contracts details on the duration in 2025. These contracts are crucial for the long-term profitability of your installation, guaranteeing a fixed purchase price for the energy you sell. For the resale of photovoltaic energy, EDF OA offers energy purchase contracts over 20 years in 2025, ensuring a stable and predictable income.
6. Profitability study
It is crucial to carry out a profitability study before investing in solar panels. Why? Because each project is unique. A profitability study allows you to measure the economic efficiency of your installation and its feasibility. This will avoid potential financial losses.
The study takes into account several factors, such as the number of solar panels, the volume of annual electricity production, the consumption of your household and the choice between resale or self-consumption.
The return on investment (ROI) materialises when the savings made through self-consumption and/or the sale of electricity exceed the initial investment. To ensure the profitability of your project, it is important to fully understand all the financial aspects.
A well-conducted profitability study will give you a clear vision of the expected costs and benefits of your solar installation. It will help you make an informed decision and optimise your investment.
Here are some elements to consider for a complete profitability study:
- The initial cost of the installation (panels, inverter, installation, etc.).
- The financial aid available (self-consumption premium, tax credit, etc.).
- The income generated by the sale of surplus electricity.
- The savings made on your electricity bill thanks to self-consumption.
- The maintenance and insurance costs of the installation.
It is possible to improve the energy efficiency of your HVAC system and therefore the profitability of your installation by using a production monitoring application, intelligent control or a storage system.
