Reducing the energy bill is at the heart of everyone's concerns given the annual increases in it. For 2020, the government confirms a 2,4% increase in the electricity bill as of February, which corresponds to 21 euros more.
Fortunately, today it is possible to produce your own energy and to consume it directly thanks to solar self-consumption. This practice is increasingly 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 that designates the fact of produce your own electricity and consume it instantly. This is a particularly effective solution for reducing your energy bill, which remains one of the biggest spending items for households in France. Example of a installation in solar self-consumption.
However, it is important not to confuse self-consumption and 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 in 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 to benefit 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 gradual end to the use of fossil and nuclear energies. 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
In addition, depending on how you are equipped, solar energy allows you to meet all your needs: heating, lighting, water heaters, household appliances, etc. Namely that it is even possible to charge electric cars by this means, in particular by extending the production surface of the panels to 50%. Using a solar installation while driving an electric car is definitely a way to proactively contribute to the fight against pollution by reducing carbon emissions into the atmosphere.
Solar self-consumption is economical
Its second greatest interest is obviously that it allows savings of up to 50% on the energy bill, depending on the optimization of electricity production and equipment. And this is not only a saving on the price of the kWh, since the amount of the subscription is also concerned. It 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 expense item as well.
Resale possibilities in case of overproduction in self-consumption
Finally, one of the advantages and not the least is that you have the possibility of reselling the surplus 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 as a private individual, and wherever you are in France. It is true that the sunshine conditions in the south of France make it more conducive to the use of solar panels, which does not mean that other regions cannot be favorable to it. The important thing is to choose the right equipment and especially to proceed with thesolar potential study of your home. To do this, you can contact a specialist in solar self-consumption who will diagnose your home.
As for the equipment, you can choose the photovoltaic panels, which look exactly like conventional solar panels and have been specially designed for home use. These panels have cells that convert 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 should then be composed of one or more solar panels and an inverter. You can also add a battery to store the 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 want to benefit from state aid. This second option is more than recommended since it conditions the obtaining of government aid and guarantees you an installation within 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 sliding scale tariff will apply as the power of the installation increases.
The average price of the installation, including the material, the installation, the connection, the commissioning and the administrative procedures are 8500 euros for 3 kWp, 14 euros for 000 kWp, and 6 euros for 18 kWp. These prices may be reduced respectively by 000 euros, 9 euros and 7330 euros if you benefit from the state bonus.
Regarding the lifespan of the kits, you will benefit from a 25 warranty. This ensures more precisely that after 25 years, the power of your installation will correspond to at least 83% of the initial power.
Regarding profitability, statistics prove that solar self-consumption thanks to photovoltaic panels has a rate of return 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.
