Renovations, heritage and volumes

For your renovation projects in Au, data from the federal building register indicates that at least 9 buildings are subject to heritage protection, requiring early coordination with the municipality to secure necessary permits. Please note that data coverage is partial for certain indicators: information regarding the year of renovation and building volume according to the SIA 416 standard is not available in the current records. We advise you to verify these technical specifications directly with local authorities before proceeding with modernization plans or insulation upgrades to ensure your project aligns with municipal requirements and building standards.

Why invest in solar storage?

Energy storage transforms your photovoltaic system. During sunny periods, your panels often produce more than your home consumes immediately. Without storage, this surplus is injected into the grid.

With a battery, this energy is kept for evening use or demand spikes. This allows you to cover your evening energy needs, reducing your overall bill. RenoIndex helps you estimate your budget for a high-performance installation.

Remember to check compatibility with your existing inverter before buying to ensure a smooth installation. Proper sizing ensures your system is optimized for your specific home consumption patterns.

Ideal battery sizing

A successful project requires rigorous sizing. A common mistake is to base capacity only on panel power. It is better to size capacity by evening consumption, not panel power.

Analyze your consumption habits to choose a battery that matches your actual use after sunset. A system that is too large represents an unnecessary cost, while a system that is too small will not cover your needs.

Use the RenoIndex estimator to explore different price options and capacities available on the current Swiss market to ensure you find the right balance.

Compatibility and technical installation

Before any installation, ensure your hardware is compatible. Check compatibility with your existing inverter before buying your new storage unit.

Some inverters are hybrid models, which greatly simplifies adding a battery, while others require additional components like a second dedicated storage inverter.

A professional installer can assess the state of your current infrastructure to avoid unexpected costs. To get reliable price ranges for storage solutions, consult the RenoIndex website.

Meticulous technical preparation secures your investment and ensures an optimal lifespan for your system.

Maintenance and durability

A solar battery requires little maintenance, but regular monitoring is recommended. Modern systems often include apps to track charge cycles and battery health. Avoid exposing the unit to extreme temperatures to preserve its capacity over the years.

By following manufacturer recommendations, you maximize the lifespan of your equipment. If you are planning to add a battery, remember to use RenoIndex to get a cost estimate and compare different technologies.

Good maintenance ensures your investment continues to provide significant savings throughout its service life.

Frequently asked questions

What is the average lifespan of a solar battery?

Most modern solar batteries have a lifespan between 10 and 20 years. This longevity depends heavily on the quality of the technology and usage conditions, such as respecting charge cycles. Use RenoIndex to estimate your project costs and find the right solution.

Is a hybrid inverter necessary?

It is not strictly required, but highly recommended to simplify installation. A hybrid inverter manages current from both panels and battery directly. With a standard inverter, you might need a second one dedicated to storage. Check compatibility details at RenoIndex.

How do I estimate the cost of my installation?

Costs vary based on storage capacity and the specific technical requirements of your home. To get a precise, personalized price range without obligation, access the free RenoIndex estimator. This will help you plan your budget before contacting local installers.

Is a battery profitable if I already have panels?

Yes, if your production regularly exceeds your daytime consumption. By storing surplus, you avoid buying grid electricity in the evening, increasing your self-consumption rate. Use the RenoIndex estimator to calculate if this investment will be profitable for your specific situation.
