Why install a solar battery?
A battery is worthwhile when solar output clearly exceeds your daytime use. By storing the surplus, you avoid selling power to the grid at low rates and use it when you are home.
This significantly increases your self-consumption rate and reduces reliance on the grid. In the long term, this strategy improves the profitability of your solar installation by keeping your locally produced green energy.
It is a smart investment for any homeowner in Wettingen looking to secure their future energy costs.
Sizing and technical compatibility
Sizing is crucial for system efficiency. It is recommended to size capacity by evening consumption, not panel power. Over-sizing means the battery is rarely full, while under-sizing fails to cover your needs.
Before buying, always check compatibility with your existing inverter. Some systems require specific hybrid inverters.
Consulting a local professional in Wettingen will help you harmonize new equipment with your existing setup to ensure optimal performance and longevity for your solar installation.
Legal framework and steps
In Wettingen, as everywhere in Switzerland, energy storage installations must meet applicable electrical safety standards. Ensure installation is performed by qualified technicians to satisfy network operator requirements.
While usually permitted without specific building permits, check with your municipality regarding any requirements for technical or aesthetic integration.
Thorough planning with local professionals ensures full project compliance while maintaining the safety of your home.
Estimation and budget planning
Budget planning is essential for project success. Costs vary based on technology, capacity, and complexity of integration with your existing system. To get a realistic estimate, use our free RenoIndex tool.
It provides a price range adapted to the Swiss market, allowing you to easily compare options. Once the budget is set, request multiple quotes from trusted installers in the Canton of Aargau.
Comparing these offers ensures you get the best value for your storage battery.

Frequently asked questions
Is a battery always profitable?
Profitability depends on your current self-consumption rate. If you use little power at night, the investment may take longer to pay off. However, given rising electricity costs, a battery is a key asset to stabilize your energy bills and increase independence.
How long does a battery last?
Most modern solar batteries use lithium-ion technology. Their lifespan is generally between 10 and 15 years. This life cycle depends on usage patterns and the daily depth of discharge for the system.
Can I install the battery myself?
Electrical installation must be done by qualified professionals to ensure safety and compliance with Swiss standards. Mishandling may pose fire risks and void your home insurance coverage.
Does the battery work during an outage?
It depends on your system. Some models offer an integrated backup function, while others shut down for safety during a grid outage. Check this option during your installation planning.
