Why install a solar battery
A battery is worthwhile when solar output clearly exceeds your daytime use. By storing surplus energy, you avoid buying expensive electricity from the grid in the evenings or at night.
This significantly increases your self-consumption rate and reduces your dependence on grid electricity rates. Before investing, analyze your daily consumption profile to determine if the purchase is economically viable.
Use RenoIndex to calculate your project precisely and compare the potential costs for this type of installation in Buchs.
Sizing and capacity
Sizing is a crucial step for the profitability of your battery. Contrary to popular belief, you should size the capacity according to your evening consumption rather than the total power of your solar panels.
A battery that is too large represents an unnecessary cost, while one that is too small will not cover your needs. Accurately assess your household's energy consumption during hours without sunlight.
Use our RenoIndex estimator to receive advice on the ideal battery size based on your usage and get a clear price range.
Technical compatibility
Before buying a new battery, you must carefully check compatibility with your existing inverter. Some systems work with direct current (DC) and others with alternating current (AC).
If your current inverter is not a hybrid model, you may need additional components or a dedicated battery inverter. This check is essential to ensure system efficiency and avoid technical complications during installation.
RenoIndex supports you in this process by providing a cost estimate that includes all necessary components to ensure your solar setup in Buchs is consistent.
Planning and installation
A successful installation requires rigorous planning, including choosing the right location for the battery, which must be temperate and secure.
Although the Canton of Aargau does not impose specific municipal rules for home energy storage, compliance with Swiss electrical safety standards is mandatory. Hire qualified professionals for the work to ensure a compliant installation.

Frequently asked questions
How long does a solar battery last?
On average, a modern solar battery lasts between 10 and 15 years. Its lifespan depends on the quality of the cells, the number of charge cycles, and ambient conditions such as temperature. Regular maintenance helps maintain its performance over time.
Do I need a permit to install a battery?
Generally, there is no specific building permit required for a home battery, but the work must comply with Swiss electrical standards. It is advisable to check with your insurer and the local grid operator for any specific safety guidelines.
Where should I install the battery?
The battery should be placed in a dry, ventilated area with a stable temperature, ideally between 5 and 25 degrees Celsius. Avoid areas directly exposed to sunlight, damp places like wet basements, or outdoor spaces unprotected from extreme climate variations.
How can I estimate my total project costs?
