Thinking of installing a residential battery to power your home, but wondering how many you’d need ? In this article, we’ll guide you through determine how many batteries you need based on your energy needs.
Whether you’re looking to reduce your electricity bill or be self-sufficient in the event of a power cut Choosing the right battery capacity is crucial. Discover our tips for calculating the ideal size for your home energy storage system.
Reduce dependence on the public electricity grid with photovoltaic panels
Photovoltaic panels offer an effective solution for reducing dependence on the public electricity grid by producing energy from the sun. By installing these panels on a roof or in a sunny area, homeowners can generate their own electricity and thus reduce their consumption from the traditional electricity grid.
However, it is essential to be able to store the energy produced to guarantee its continued use, even when the sun isn’t shining. This is why energy storage is becoming a key element in the transition to greater energy autonomy.
Calculate your energy footprint for a smooth transition to renewables
The efficiency of your system depends on a careful assessment of your daily electricity consumption. By analyzing your household’s specific energy needs and identifying peak consumption periods, you can choose the optimum size for your solar installation and storage device.
This precise calculation will guarantee maximum energy autonomy while minimizing your impact on the public grid. By aligning your renewable resources with your consumption habits, you actively contribute to the transition to a more sustainable way of life.
Correctly size solar panels and home batteries
In order to achieve the ambitious target set out in the French Multiannual Energy Programme (Programmation pluriannuelle de l’énergie) of use 40% renewable energy it is crucial to correctly size solar panels and household batteries.
Indeed, by adapting the size of the solar panels to the household’s electricity consumption and choosing home batteries with adequate storage capacity, homeowners will be able to maximize their renewable energy production. Precise sizing will thus make it possible to optimize the use of renewable energies and actively contribute to the energy transition.
According to some estimates, a household consumes around 28.9 kWh per day for heating, 5.6 kWh per day for hot water, 3.2 kWh per day for cooking and 8.7 kWh per day for other appliances, equivalent to a total consumption of 46.4 kWh per day.
To efficiently supply your home with electricity while reducing your dependence on the public grid, it is recommended to invest in batteries with a capacity of at least 50 kWh.
Taking into account an average household consumption estimated at 46.4 kWh per day, this represents approximately 32.48 kWh to cover 70% of this consumption. To compensate for these requirements, the installation of batteries with a storage capacity of around 35 kWh would be a suitable solution.
