• This model simplifies management: no need for storage systems, which reduces costs and constraints.
• Participating in total resale helps France produce more renewable energy and reduce its carbon emissions.
• Purchase prices are influenced by government decisions, so it’s useful to stay informed of developments.
• Aid and tax benefits exist to support total resale installations, making the investment more attractive.

Understanding total photovoltaic resale

Definition and fundamental principles

Total photovoltaic resale involves installing solar panels and selling all the electricity produced to the public grid. Unlike self-consumption, where the electricity produced is used for the producer’s own needs, here, all the energy is injected into the grid and sold to an energy supplier. This model allows you to transform your roof or land into a stable source of income. Total resale is a simple way to participate in the energy transition while benefiting from a guaranteed income.

Difference with self-consumption

The main distinction between total resale and self-consumption lies in the use of the electricity produced. In self-consumption, you consume some or all of the electricity that your solar panels produce, and you can resell the surplus. With total resale, you don’t consume any of the electricity produced; it’s all sold. This means that you continue to buy your electricity from your usual supplier. The choice between these two options depends on your energy needs, your geographical location and your financial objectives. It’s important to fully understand the advantages of total resale to make an informed choice.

Regulatory framework in France

In France, total photovoltaic resale is governed by specific regulations, in particular by orders and decrees that set the purchase prices for the electricity produced. The obligation to purchase (OA) is a key mechanism that guarantees solar energy producers a fixed purchase price for a specified period, generally 20 years. To be able to benefit from this system, it’s necessary to comply with certain technical and administrative conditions, such as using a QualiPV certified installer and obtaining a connection to the grid.

The regulatory framework aims to encourage the development of solar energy in France by offering financial security to investors and simplifying administrative procedures. It’s essential to keep abreast of changes in these regulations to optimise the profitability of your photovoltaic installation and ensure its compliance. HVAC systems are at the heart of this transformation.

Here is a summary table of the main differences between total resale and self-consumption:

Characteristic	Total Resale	Self-consumption
Use of electricity	Full sale to the grid	Own consumption and sale of surplus
Source of income	Sale of electricity produced	Savings on electricity bill and sale of surplus
Energy independence	None	Partial or total, depending on consumption
Complexity	Simple	More complex (management of consumption and surplus)

Financial advantages of total photovoltaic resale

The total resale of photovoltaic electricity represents an attractive financial opportunity for individuals and businesses. This economic model, which consists of selling all the electricity produced by your solar panels to the grid, offers several notable financial advantages. It’s important to fully understand these advantages to assess the relevance of this option compared to self-consumption.

Guaranteed long-term income

One of the main advantages of total resale is the guarantee of stable income over a prolonged period. Electricity purchase contracts are generally concluded for a period of 20 years, which offers considerable financial visibility. These contracts are established with energy suppliers such as EDF Obligation d’Achat, who undertake to buy your production at a fixed price. It’s a bit like receiving a regular rent, which allows you to plan your finances over the long term.

Attractive and stable purchase prices

The purchase prices of photovoltaic electricity are set by the public authorities and are designed to encourage the development of the solar sector. Although these prices have changed over time, they remain attractive and generate worthwhile income. The stability of these prices, guaranteed by purchase contracts, protects producers from fluctuations in the electricity market. It’s important to note that prices vary according to the power of the installation and its geographical location.

Return on initial investment

The total resale of photovoltaic electricity can enable you to quickly amortise the initial investment in solar panels. The income generated by the sale of electricity helps to cover the costs of installation, maintenance and connection to the grid. The return on investment depends on several factors, such as the power of the installation, the amount of sunshine in the region and the purchase price of electricity. It’s therefore essential to carry out a precise feasibility study before embarking on a total resale project. To be able to resell the electricity produced by your photovoltaic solar panels, you must use a professional with a qualification for solar installation photovoltaic (QualiPV).

The total resale of photovoltaic electricity offers a stable and predictable source of income, thus contributing to the profitability of the initial investment and to long-term financial planning.

Simplicity of management and operation

Total photovoltaic resale stands out for its simplicity of management and operation, offering an attractive alternative for those who want to invest in solar energy without the complexities associated with self-consumption.

No need for energy storage

One of the main advantages of total resale is that there’s no need to store energy. All the electricity produced by your solar panels is directly injected into the public grid, eliminating the need to invest in costly batteries and manage their maintenance. This greatly simplifies installation and reduces initial costs. You don’t have to worry about storage capacity, charge/discharge cycles, or battery obsolescence. This is a significant aspect, especially when you consider the lifespan of photovoltaic installations.

Optimisation of available space

By opting for total resale, you optimise the use of available space on your roof or land. Since it’s not necessary to size the installation according to your personal consumption, you can install a maximum of solar panels to maximise electricity production and, consequently, your income. This approach is particularly attractive if you have a large surface area exposed to the sun. In addition, the absence of batteries frees up additional space, which can be an advantage if you have space constraints.

Simplified administrative process

The administrative process linked to total resale is generally simpler than that of self-consumption. The procedures for connecting to the grid are standardised, and electricity purchase contracts are offered by approved energy suppliers. Of course, there are always forms to fill out and authorisations to obtain, but the whole process is well-established. It’s important to find out about connection requests and follow the steps indicated by the grid operator to avoid any delays or complications. In general, administrative monitoring is less burdensome than with other options.

Total photovoltaic resale offers a turnkey solution for producing clean energy and generating income, without the technical and administrative constraints often associated with self-consumption. It’s a wise choice for those looking for simplicity and efficiency.

Impact on the national energy transition

The total resale of photovoltaic electricity plays a significant role in France’s energy transition. By injecting renewable electricity directly into the grid, it contributes to various national objectives.

Contribution to renewable energy production

Total photovoltaic resale increases the share of renewable energies in the French energy mix. It diversifies production sources and reduces dependence on fossil fuels. Photovoltaic installations, particularly those that practice total resale, actively participate in achieving the objectives set by France in terms of renewable energy development. It’s a concrete way for individuals and businesses to get involved in clean energy production. Increasing renewable energy production is a central pillar of French energy policy, and total resale contributes directly to this. It’s important to note that the electricity buyback price is a key element in encouraging this production.

Reduction of carbon emissions

By substituting part of the electricity production from carbon-based sources (coal, gas, fuel oil) with solar electricity, total resale contributes to the reduction of greenhouse gas emissions. Each kilowatt hour (kWh) of solar electricity injected into the grid avoids the emission of a certain amount of CO2. This reduction is essential to combat climate change and achieve the carbon neutrality targets set by France. Total resale, by promoting the development of solar energy, therefore participates in the decarbonisation of the energy sector.

Support for the development of the solar sector

Total photovoltaic resale supports the development of the entire solar sector in France. By ensuring an income for producers, it encourages investment in photovoltaic installations and stimulates technological innovation. This support translates into:

• The creation of jobs in the installation, maintenance and manufacture of solar panels.
• The development of new technologies to improve panel performance and reduce production costs.
• The emergence of new companies and new economic models in the solar energy sector.

The solar sector is a growing sector, and total photovoltaic resale plays an important role in its development. By ensuring a market for solar electricity, it encourages investment and innovation, which contributes to the competitiveness of the sector and its ability to meet France’s energy needs. It’s important to monitor the evolution of sales prices to understand the impact on the sector.

Evolution of purchase prices and prospects

Analysis of current price trends

Purchase prices for photovoltaic electricity have fluctuated significantly in recent years. Overall, there has been a downward trend since 2023, influenced by several factors. The decrease in the installation costs of solar panels lower costs and the desire of the public authorities to adapt aid to the economic context of the sector are the main drivers of this evolution. The degression coefficient applied quarterly by the Energy Regulatory Commission (CRE) automatically adjusts prices, thus reflecting market realities.

Influence of recent decrees and orders

Several regulatory texts have recently modified the landscape of photovoltaic electricity buyback. The amending order S21, published in the Official Journal, has notably impacted the tariff conditions and the premiums for self-consumption. These decrees aim to regulate the development of solar energy in France, taking into account the objectives of the energy transition and budgetary constraints. It’s therefore essential to closely monitor the evolution of these texts to anticipate future changes. The tertiary decree is an example of a text that has a significant impact on the sector.

Forecasts for the years ahead

It’s difficult to predict with certainty the evolution of purchase prices in the years to come. However, several elements make it possible to outline possible scenarios. The downward trajectory of installation costs should continue, which could lead to a further decrease in prices. In addition, France’s ambitious renewable energy targets could encourage the public authorities to maintain a certain level of support for the sector, in order to achieve the set objectives. It’s therefore likely that prices will continue to evolve, but in a more moderate way than in recent years. It’s important to note that total resale contracts have a limited duration, and that after 20 years, it will be necessary to find another solution.

Eligibility criteria and administrative procedures

Conditions required for total resale

To be eligible for the total resale of your photovoltaic production, several conditions must be met. It’s imperative that the installation is connected to the public electricity distribution grid. In addition, the power of the installation is a determining factor, often capped according to the regulations in force. Integration into the building is also an important criterion, favouring installations that integrate aesthetically with the roof or the structure of the building.

Here are the main criteria to consider:

• Connection to the public electricity grid.
• Compliance with electrical safety standards (Consuel).
• Installation power compliant with regulatory thresholds.
• Type of panel integration (building integration preferred).

Role of qualified professionals (QualiPV)

The use of qualified professionals, in particular those certified QualiPV, is strongly recommended, even compulsory, to guarantee the conformity and performance of your installation. These professionals have the necessary expertise to correctly size your installation, carry out the work according to the rules of the art and assist you in the administrative procedures. Their certification attests to their competence and their commitment to quality. Using a QualiPV installer is often a condition for benefiting from financial aid and preferential purchase prices. It’s important to choose your installer carefully to avoid subsequent problems.

Procedure for connecting to the grid

The procedure for connecting to the grid is a crucial step for the total resale of your electricity. It involves several players, including the grid operator (Enedis or other ELD) and your installer. The first step is to submit a connection request to the grid operator. The latter will study the feasibility of the connection and propose a quote. Once the quote has been accepted and the work carried out, a certificate of conformity (Consuel) is required. Finally, a purchase contract is signed with EDF Obligation d’Achat (OA) or another approved buyer. It’s important to fully understand the steps of the resale of the surplus to avoid unpleasant surprises.

The complexity of the administrative procedures can discourage some project promoters. It’s therefore essential to be accompanied by competent professionals and to be well informed about the different steps to follow. Good preparation is the key to a successful project.

Here is a simplified overview of the procedure:

1. Connection request to the grid operator.
2. Completion of connection work.
3. Obtaining the Consuel certificate of conformity.
4. Signing of the purchase contract with EDF OA or another buyer.

Comparison with self-consumption with resale of surplus

Analysis of economic models

Total resale and self-consumption with resale of surplus represent two distinct approaches to the management of solar energy produced. Total resale involves transferring all production to the electricity grid, thus generating an income based on a guaranteed purchase price. Self-consumption with resale of surplus, on the other hand, favours the consumption of energy produced on site, injecting only the surplus into the grid. This latter option reduces dependence on the grid and lowers electricity bills.

The choice between these models depends on several factors, including the energy needs of the household, the consumption profile, and the purchase prices offered by energy suppliers. It’s important to carefully evaluate these elements to determine the most suitable model.

Advantages and disadvantages of each option

Each option has advantages and disadvantages that should be carefully considered:

• Total Resale:
  • Advantages: Stable and guaranteed income over a long period, simplicity of management.
  • Disadvantages: Dependence on purchase prices, no direct reduction in electricity bill.
• Self-consumption with Resale of Surplus:
  • Advantages: Reduction of electricity bill, valorisation of energy produced, additional income thanks to the sale of surplus.
  • Disadvantages: Requires adaptation of consumption habits, less predictable income than total resale.

Self-consumption with sale of surplus is often seen as an advantageous compromise, combining the benefits of renewable energy production with a reduction in energy costs. However, it’s essential to properly size the photovoltaic installation to optimise self-consumption and minimise the surplus injected into the grid.

Relevant application scenarios

The choice between total resale and self-consumption with resale of surplus depends on the specific situation of each installation. Here are some relevant application scenarios:

1. Households with high electricity consumption during the day: Self-consumption with resale of surplus is particularly suitable, as it allows you to directly consume the energy produced by the solar panels, thus reducing dependence on the grid. energy consumption is reduced.
2. Installations located in areas with optimal sunshine: Total resale can be attractive, as it maximises the income generated by solar energy production. The HVAC systems must be carefully evaluated.
3. Tertiary buildings with constant energy needs: Self-consumption with resale of surplus can help reduce operating costs and improve the building’s energy performance. The HVAC systems must be carefully evaluated.

In conclusion, the choice between these two options requires an in-depth analysis of the energy needs, purchase prices, and financial objectives of each project. Self-consumption with resale of surplus is often the most profitable solution, as it combines the advantages of renewable energy production with a reduction in energy costs. However, total resale can be an attractive option in certain specific cases, particularly for installations located in areas with high sunshine or for owners wishing to favour simplicity of management. The ecological solutions must be carefully evaluated.

Tax incentives and government aid

The implementation of a photovoltaic installation in total resale can be significantly alleviated thanks to various tax incentives and government aid. These mechanisms aim to encourage the production of renewable energy and make the investment more attractive.

Reduced VAT rate for small installations

For small photovoltaic installations, a reduced VAT rate may apply. Generally, this reduced rate concerns installations with a power of less than or equal to 3 kWp. This threshold is important, as it allows you to benefit from a lower VAT rate on the purchase of equipment and labour, thus reducing the initial cost of the project. It’s important to check the eligibility conditions, as they may change depending on the legislation in force. For example, ecological solutions may be eligible for this reduced rate.

Investment support mechanisms

Several investment support mechanisms are available to encourage total photovoltaic resale. This aid can take the form of direct subsidies, subsidised loans or tax credits. Eligibility for these mechanisms depends on several factors, such as the location of the installation, its power, and compliance with certain environmental standards. It’s therefore essential to inquire with the competent organisations, such as ADEME or the local authorities, to find out about the available aid and the conditions to be met. Regional aid can be particularly attractive, as it’s often cumulative with national aid.

Eligibility for investment premiums

Investment premiums represent significant financial aid for total photovoltaic resale projects. These premiums are generally paid by the State or by mandated organisations, and their amount depends on the power of the installation. These premiums aim to compensate for part of the initial cost of the installation and improve the profitability of the project. To be eligible, it’s imperative to comply with certain conditions, in particular with regard to the quality of the equipment and compliance with installation standards. It’s also important to use a QualiPV certified installer, as this certification is often required to benefit from the premiums. HVAC systems can also benefit from these premiums if integrated into a global energy efficiency approach.

It’s crucial to carefully study the various aid mechanisms and tax incentives available before embarking on a total photovoltaic resale project. A good knowledge of these mechanisms allows you to optimise the financing of the project and improve its profitability. It’s also recommended to be accompanied by a professional to carry out the administrative procedures and ensure that you comply with all the eligibility conditions.

Optimisation of photovoltaic production

Importance of panel orientation and inclination

The orientation and inclination of solar panels are determining factors in maximising electricity production. A south-facing orientation is generally ideal in the northern hemisphere, as it allows you to capture the maximum amount of direct sunlight throughout the day. The optimal inclination, on the other hand, varies according to the latitude of the installation site. In France, an inclination equal to the latitude is often recommended for maximum annual production. However, it’s possible to adjust the inclination to favour production in winter or summer, depending on needs. It’s important to note that simulation tools exist to determine the ideal orientation and inclination according to the specificities of the site.

Maintenance and monitoring of installations

Regular maintenance is essential to guarantee the optimal performance and durability of photovoltaic installations. This includes cleaning the panels to remove dust, leaves and other debris that can reduce the absorption of sunlight. It’s also important to regularly check the condition of the cables, connectors and inverter to detect any problems. Regular monitoring of electricity production makes it possible to quickly detect any drop in performance and identify the possible causes. Remote monitoring systems can be installed to facilitate this monitoring. The durability and reliability of photovoltaic solar panels are recognised, with a lifespan of up to 40 years, subject to appropriate maintenance.

Innovative technologies for increased efficiency

The photovoltaic sector is constantly evolving, with the emergence of new technologies aimed at improving the efficiency of solar panels. These technologies include high-efficiency solar cells, bifacial panels that capture light on both sides, and solar tracking systems that automatically orient the panels towards the sun throughout the day. Agrivoltaics, which combines agricultural production and solar electricity production, also represents an innovative approach to optimising land use. The integration of renewable energies into HVAC systems significantly reduces greenhouse gas emissions. These technological advances contribute to making total photovoltaic resale even more attractive and profitable. It’s important to keep abreast of the latest innovations to optimise photovoltaic production and maximise the income generated by the sale of electricity.

Total photovoltaic resale and property valuation

Increase in asset value

Total photovoltaic resale can significantly increase the value of your property. An operational photovoltaic system is seen as a major asset by potential buyers, as it represents a stable source of income and a contribution to the environment. The installation of solar panels can therefore result in a capital gain when reselling your property. It’s important to note that the profitability of the installation, as well as its remaining lifespan, are key factors in this valuation.

Attractiveness for future buyers

Properties equipped with total resale photovoltaic systems attract an environmentally conscious public interested in energy savings. These buyers are often willing to pay a higher price for a property that generates passive income and reduces their carbon footprint. The argument of HVAC energy performance is a major asset in the purchasing decision. In addition, the simplicity of managing total resale, without the need for energy storage, is an additional argument to attract buyers.

Environmental and economic benefits

Total photovoltaic resale offers a double advantage: it contributes to the production of renewable energy and generates income for the owner. This combination is increasingly sought after by property buyers, who are sensitive to environmental issues and economic opportunities. By opting for total resale, you actively participate in the energy transition and enhance the value of your property. It’s important to fully understand the buyback prices to assess long-term profitability.

Total photovoltaic resale represents a sustainable investment that enhances your assets while contributing to a cleaner energy future. It offers a unique opportunity to reconcile economic interests and environmental commitment.

Here are some concrete benefits:

• Reduction of the carbon footprint of the accommodation.
