Solar panels for professionals: what use?

Renewable energy is of increasing interest to professionals. We are talking about solar panels. These become the most accessible and easy solution to generate income from a natural source. In addition to this, being environmentally friendly gives the company an innovative and responsible image vis-à-vis its competitors and therefore can result in higher sales. If you want to install solar panels and take advantage of their benefits, read this article to get a clear idea of the subject.

What is the difference with the individual?

There are many differences between the installation of solar panels for professionals and for individuals. Here are some differential points so that you have a clearer idea about the systems and the installation process.

Size :

Size is the most important distinction when it comes to differentiating between solar panels for a business and solar panels for a residential space. This is because the average size of a commercial solar panel is 78 inches by 39 inches and contains 96 cells, while the residential solar panel measures 65 inches by 39 inches and contains 72 cells. Besides, many people prefer to install commercial size solar panels for their homes because they produce more electricity and are more efficient.

The installation:

Whether in business or at home, the technical characteristics of an installation less than or equal to 10 kW are the same but the installation differs a little. This is because commercial solar panels are generally easy to install as they are attached to a flat roof with a non-penetrating weighted mounting system. As for residential homes, they need the panels to be flush with their shingles, which requires a more delicate and much slower installation process. It may take up to a month to complete.


Commercial solar energy is more efficient than residential solar energy. It actually produces more energy since the panels are larger than residential panels.

Financing by a third-party investor:

Individuals must finance their photovoltaic installation on their own or through a loan. However, professionals benefit from an additional option: a third-party investment formula. In this case, the company does not invest a cent in the installation. It can thus conserve its capital and devote it to its growth while reducing its electricity bill.

What are the interests of installing solar panels as a professional?

The benefits of installing solar panels for your business are numerous. We offer you a list of its benefits so you can take the plunge:

Solar energy is a free and almost inexhaustible source of energy:

Thanks to the installation of solar panels, you will produce your own electricity from an inexhaustible and free source of energy: the sun. Current solar panels have a lifespan of almost 30 years. During all these years, you are sure to have a guaranteed quantity of electricity at a fixed price.

Guaranteed return on investment:

Companies benefit from many taxes and financial advantages such as the 13.5% tax deduction of your investment, the right to green certificates for the electricity you generate with your solar panels, etc. Thus, you benefit from a significant ROI.

A high rate of self-consumption:

Self-consumption is when you consume a maximum of electricity produced by yourself. Thus, insofar as the production of your photovoltaic panels directly feeds your electrical equipment, the needs of your company are then more widely covered, thus reducing your electricity bills.

An eco-responsible approach to promote:

Solar energy is a clean, green, and self-sufficient source of energy. The installation of solar panels for companies thus makes it possible to contribute to a sustainable future. It’s a great way to limit your carbon footprint. In doing so, your company will mark its ecological commitment which will enhance its brand image vis-à-vis employees, partners, and customers.

State financial aid for the installation of professional solar panels:

Several state financial aids and support mechanisms are available to companies that want to invest in solar panels. Here is an example of a list of help you can benefit from:

The self-consumption premium:

Photovoltaic self-consumption is the consumption of its own production of electricity through the installation of solar panels. This type of installation then makes it possible to benefit from the self-consumption premium (also called the investment premium). This is a payment that extends over the first 5 years of operation. Each year you receive ⅕ of the total amount. To be eligible for this bonus, the power of your installation must be between 3 kW and 100 kW.

Deductible VAT:

The acquisition of a photovoltaic installation allows professionals to benefit from a VAT recovery. This VAT credit amounts to 20% of the total amount of the installation.


The reduction of the IFER (Flat-rate Taxation of Network Companies) by half:

Following the application of article 123 of the 2020 Finance Law, the amount of all installations put into service after January 1, 2021, will be halved to reach an amount of € 3.155 per kWh / year during the first 20 instead tax years 7.65 € per kWh / year. In order to be eligible for this reduction, the installation of professional solar panels must have a power of more than 100 kW.

Where to install solar panels when you are a company?

Professional solar panels can be installed either on rooftops (this is the classic method) or in parking lots (in a creative way).

Car park

The photovoltaic shade structures appeared in 2006. It is a solution to parking coverage that can accommodate cars while producing solar electricity. This structure brings many advantages to different actors, whether they are customers, employees or other users. Indeed, parking shades allow you to use your parking areas to produce energy and reduce your carbon footprint while helping to protect cars from the sun and bad weather.


Roofs of its buildings

The installation of professional solar panels on the roof is the most common installation. All you need is a clear, well-oriented section of the roof in order to have optimal performance. This type of installation offers many benefits such as the valuation of unoccupied surfaces since the roofs offer perfect support for solar panels. The inclination improves the performance of the panels and prevents the accumulation of dirt. On the other hand, the installation is universal, so it is compatible with most covers.

Who to contact for the installation of solar panels in his company?

Before starting to install the panels, it is necessary to follow an administrative process that can be long and complex. To do this, it is crucial to call a certified expert to support and guide you during all the administrative steps:

  • The first step is to contact the town hall to identify any possible urban planning constraints on the site. This process can take up to a month.
  • Then, a declaration must be made to DIDEME (Department of Energy Demand and Markets) to carry out a connection and operation contract which will include:
    • The information collection sheets for your installation.
    • The receipt for the building permit or the declaration of works.
    • The diagram of the installation.
    • The civil liability insurance certificate.
    • The Consuel’s certificate of conformity and the documents attesting to the conformity with the standards of the products to be installed.
  • Subsequently, you will need to obtain an access and operation connection contract (CRAE) from ERDF or a competing supplier. It may take two to three months.
  • Finally, you will obtain the electricity purchase certificate which represents a commitment to buy back electricity from a producer (this procedure can take up to three months).

As mentioned, these administrative procedures can be very long and maybe boring, hence the need to opt for the services of a professional. It will save you time and money!

The installation of professional solar panels is becoming more and more widespread. Solar energy is a free and inexhaustible natural source and the financial support mechanisms available to businesses are increasing: tax assistance or regional subsidies, bonuses, purchase prices, etc., solar panels for professionals are becoming a solution. viable with a certain return on investment.
