Solar energy: a sustainable choice for a future-oriented home
Provide your home with clean, inexhaustible and efficient energy. Thanks to photovoltaics, your house produces its own electricity day after day, thus reducing your expenses, improving your comfort and decreasing your environmental impact. More autonomy, less emissions: a sustainable solution that transforms your daily life and prepares the future of your household.
A concrete example
A household equipped with a 6 kWp installationwith a battery, produces an average of 6,000 kWh of electricity per year.
- Of this production,70 to 90% is consumed directly, which significantly reduces the energy bill.
- With savings of around€1,600 per year, the installation is generallyrecouped within 5 to 7 years.
- As solar panels have a lifespan of25 to 30 years, this represents more than two decades of electricity produced for free.
If this same installation does not include a battery;
30 to 50 %of the production is consumed directly by the household.
Theremainder (50 to 70 %)isfed back into the grid for free, becausewithout a feed-in tariff, the unused energy is simply lost.
Even if the installation remains profitable (around5 to 7 yearsdepending on usage and orientation),the annual savings are much lowerthan with a battery, as a large part of the production is not valued.
The power depends on your annual electricity consumption, the size of your roof, and your budget.
In general:
3 to 4 kWpis suitable for a small household,
5 to 6 kWpfor a family of 3–4 people,
7 kWp and morefor homes equipped with heat pumps, charging stations, or high consumers.
We carry out apersonalised studyto determine the ideal power according to your situation.
Without a battery: you consume 30 to 50% of your production. The rest is injected for free into the grid (if there is no buyback contract).
With a battery: you achieve 70 to 90% self-consumption, which significantly increases your savings and autonomy.
We will advise you on the best option based on your consumption, your installation, and your goals.
- The majority of installations areprofitable in 5 to 7 years.
- After amortisation, you benefit from20 to 25 years of free electricitydepending on the lifespan of the panels.
- An estimate of profitability is provided in yourpersonalised quote.
