Want to know more about solar energy? In this article, we explain to you how a solar installation works, what are the different technologies used, what budget to plan and the possible financial aid.

First of all, what is solar energy?

Solar energy consists, as its name suggests, in transforming sunlight into energy. It has the advantage of being ecological, free, inexhaustible and accessible everywhere. For a long time now, it has been used in passive form to heat and light homes naturally by fitting them out intelligently. More recently, solar energy has been discovered to have even greater potential with the invention of thermal and photovoltaic panels. Thermal energy is used to heat water to supply a heating system, while photovoltaic energy is used to produce electricity. The latter is by far the most interesting since electricity can be used in many areas. Nowadays, when we talk about solar energy, we generally refer to photovoltaics.

How do solar panels work?

The operation of solar panels , in this case photovoltaic, is quite simple to understand. They incorporate photovoltaic cells whose role is to transform solar energy into direct current. Following this, the electricity produced is directed to an inverter which allows the direct current to be changed to alternating current. The latter can then be routed to the electrical network of a dwelling, building or other in order to be consumed. The installation of photovoltaic panels, whether for individuals or professionals, has become very accessible in recent years. They are generally placed on the roof so as not to lose space and to be optimally oriented towards the sun. They can also be connected to the public network in order to inject the surplus electricity produced.

What are the different technologies used?

As explained above, photovoltaic panels are made up of cells. The material mainly used for their design is silicon, which has largely dominated the market for many years. However, there are two very different manufacturing technologies, which have a direct impact on the performance and cost of the panels:

Although this is rarer, it is also possible that the cells are made from very thin layers of silicon in order to make them more flexible and modular. In this way, they can for example take the form of solar tiles to completely compose the coverage of a roof.

How much does a solar installation cost?

The cost of a photovoltaic installation varies according to several criteria, but the main one is the installation power. In private individuals, the latter can generally range from 3 to 9 kWp. Thus, for a photovoltaic installation of 3kWp, it will take between 9,000 and 13,000€. The installation power chosen will depend essentially on the quantity of solar energy that you intend to produce as well as the space available for the installation of your panels. Then, of course, you will have to take into account the future performance of your installation, which will allow you to amortize the total cost of the investment via the savings made on your electricity bills. A return on investment is possible after 10 years of operation. The lifespan of photovoltaic panels being 25 years on average, this gives you plenty of time to obtain it.

Are there any aids to finance your solar installation?

The financial aids put in place for thermal and photovoltaic installations are very different. Indeed, thermal panels will most of the time be considered as energy renovation works, which gives rise to many possibilities such as zero-rate eco-loans, tax credits or even investment bonuses. . Do not hesitate to inquire about this subject to find out more. With regard to photovoltaic panels, they are not eligible for aid dedicated to energy renovation work. On the other hand, you can benefit from a self-consumption bonus if you choose an RGE-certified installer , the panels are installed on the roof and you sell the excess electricity to an energy supplier. This can help make your solar installation profitable even faster.
