When to install a solar battery
A battery is worthwhile when solar output clearly exceeds your daytime use. Most households produce the most energy while family members are away. By storing this surplus, you can use your own free electricity in the evening and at night.
This significantly increases your self-consumption rate, which is particularly advantageous given current electricity prices.
Before you start, carefully analyze your annual consumption profile to assess whether the investment will be repaid by savings on your electricity bill in the long term. Proper planning is the first step toward energy independence.
Sizing and capacity
Size capacity by evening consumption, not panel power. An oversized system represents an unnecessary cost, while a system that is too small will not cover your needs.
It is crucial to study your evening consumption habits, including the use of heating, water heaters, or heavy appliances after sunset. A qualified installer can help you calculate the ideal size in kilowatt-hours.
Keep in mind that storage efficiency decreases slightly during charge and discharge cycles, which must be factored into your energy forecasts. Plan ahead for maximum efficiency.
Technical compatibility
Check compatibility with your existing inverter before buying. If you already own solar panels, you may need to add an inverter-charger or opt for an AC coupling solution.
Some modern batteries are 'all-in-one' systems and include their own inverter, which can simplify installation but requires close compatibility with your home energy management system.
Ensure that the chosen hardware complies with Swiss electrical safety standards. Consult an expert to verify that existing wiring can support the additional load and that the software integration is conflict-free.
Budget and cost estimation
The cost of a solar battery depends on its technology, capacity, and the electrical work required for the installation. It is important to compare quotes from several local installers to obtain the best value for money.
Use the RenoIndex calculator to get a clear price range based on current market realities.
In addition to the price of the storage unit, do not forget to include labor costs for installation and any necessary updates to your electrical panel to ensure a compliant and durable installation for the decades to come.

Frequently asked questions
What is the lifespan of a solar battery?
Most modern lithium batteries have a lifespan of 10 to 20 years. Performance decreases gradually with the number of full charge cycles. Moderate use and installation in a temperature-controlled room help to extend this duration.
Does a battery provide power during a blackout?
It depends on your model and the installation. Some systems include an automatic backup function that switches to stored energy during a power outage. Carefully verify this technical option with your installer if maintaining power is a priority for you.
Is it difficult to maintain a solar battery?
Modern solar batteries require very little maintenance. They are generally equipped with intelligent management systems that optimize charging and discharging autonomously. However, it is recommended to have the connections and general condition checked annually by a professional during the maintenance of your photovoltaic system.
Can I add a battery later?
Yes, it is entirely possible to add a battery to an existing installation. You may need to opt for an AC-coupled system if your solar inverter cannot be replaced. Discuss this with a professional to evaluate the best technical solution for your current system.
