Opinion on solar self-consumption

Reducing the energy bill is at the heart of everyone's concerns given its annual increases. For 2020, the government confirms a 2,4% increase in the electricity bill from February, which corresponds to 21 euros more.

Fortunately, it is now possible to produce your own energy and consume it directly thanks to solar self-consumption. This practice is becoming more and more popular in France and is even the subject of State aid to encourage households to adopt it. Focus on all the information you need to know about solar self-consumption.

What is solar self-consumption?

Solar self-consumption is a term which designates the fact of produce your own electricity and consume it instantly. It is a particularly effective solution to reduce its energy bill, which remains one of the biggest items of household spending in France. Example of a installation in solar self-consumption.

However, it is important not to confuse self-consumption with autonomy. Indeed, autonomy implies total independence from the public network. Such an approach would require a radical revision of the mode of consumption, and a colossal investment in equipment and installation.

Self-consumption consists of directly consuming the energy produced by the panels while continuing to connect the home to the public electricity network. This solution will be easier to implement, among other significant advantages.

To be sure of benefiting from a quality solar installation that is beneficial on many points, we strongly advise you to be accompanied by a specialist in solar self-consumption.

Why is it interesting to implement solar self-consumption?

The use of solar energy is in itself a gesture that contributes to the Environmental Protection, in particular by implementing the phasing out of the use of fossil and nuclear energy. Indeed, solar energy being a renewable, green and inexhaustible energy, its use has only advantages for the environment.

A solution that meets all energy needs

Furthermore, depending on how you are equipped, solar energy allows you to meet all your needs: heating, lighting, water heaters, household appliances, etc. To know that it is even possible to charge electric cars by this means, in particular by extending the production area of ​​the panels to 50%. Using a solar installation while driving with an electric car is certainly a way to contribute proactively to the fight against pollution by reducing the emission of carbon into the atmosphere.

Solar self-consumption is economical

Its second biggest interest is obviously that it allows to realize savings of up to 50% on the energy bill, depending on the optimization of electrical production and equipment. And it is not only a saving on the price per kWh, since the amount of the subscription is also concerned. It actually appears that the cost of the subscription has increased by more than 30 euros over the last 4 years. This corresponds to an increase of 9%. Solar self-consumption will then allow you to save money on this item of expenditure as well.

Resale possibilities in case of overproduction in self-consumption

Finally, one of the advantages and not the least is that you can sell the excess energy that you produce to EDF. This can be a good way to make your equipment profitable, especially since the purchase price is 0,10 euro per kWh in the 1st quarter of 2020.

How to install solar panel devices at home while being private?

It is perfectly possible to install and use solar panel devices at home while being private, and wherever you are in France. It is true that the sunshine conditions in the south of France make it more suitable for the use of solar panels, which does not mean that the other regions cannot be favorable to it. The important thing is to choose the right equipment and especially to carry out thesolar potential study of your home. To do this, you can contact a specialist in solar self-consumption who will diagnose your home.

Regarding the equipment, you can choose the photovoltaic panels, which look exactly like conventional solar panels and which have been specially designed for home use. These panels have cells which transform the energy produced by the sun's radiation into direct current, which will then be transformed into alternating current by an inverter.

Your solar panel device must then be made up of one or more solar panels and an inverter. You can also add a battery to store excess energy, while a monitoring system can also be useful to control the electrical devices in your home, but is not mandatory.

Finally, you have the option of calling on a RGE installer if you wish to benefit from state aid. This second option is more than advisable since it conditions the obtaining of government aid and guarantees you an installation in the standards.

Self-consumption solar kit: average cost and duration of return on investment

The cost of installing a self-consumption solar kit will vary depending on the peak power of the panels. A decreasing rate will apply as the power of the installation is high.

The average installation prices, including equipment, installation, connection, start-up and administrative procedures are 8500 euros for 3 kWp, 14 euros for 000 kWp, and 6 euros for 18 kWp. These prices may be reduced by 000 euros, 9 euros and 7330 euros respectively if you benefit from the state premium.

Regarding the lifetime of the kits, you can benefit from a 25 warranty. More specifically, this ensures that after 25 years, the power of your installation will correspond to at least 83% of the initial power.

In terms of profitability, statistics show that solar self-consumption through photovoltaic panels has a rate of return of up to 9%, which is much more than a savings book or life insurance! On average, your installation will pay for itself after 10 to 12 years of use.
