Renovations, heritage and volumes
For your renovation plans in Davos, the federal building register provides key figures to consider. The median building volume is 937 m3 based on the SIA 416 standard, which is vital for scaling insulation and heating upgrades effectively. Please note that data coverage is partial, as this volume is only measured for 25 out of 1160 identified houses. Information regarding the year of renovation and heritage protection status is not available or applicable in the current official records. We recommend consulting directly with your local municipal office to confirm these details before starting any renovation projects.

Why install a solar battery
Installing a battery is a wise solution when your solar production clearly exceeds your consumption during the day. Without storage, this excess energy is fed back into the grid.
By storing this electricity for use in the evening or during periods of low sunlight, you reduce your reliance on the local power grid. It is a strategic investment to maximize the use of your existing solar panels.
To estimate the cost of this energy transition in Davos, feel free to use our RenoIndex tool, which provides a price range in CHF tailored to your specific needs.
Ideal sizing for your storage
Sizing is the most critical step in your renovation project. You should not base your choice on the total power of your solar panels, but rather on your actual electricity consumption during evening hours.
A battery that is too small will not cover your needs, while one that is too large will unnecessarily increase your investment costs. Analyze your electricity bills to determine your nighttime consumption profile.
For advice on the appropriate capacity and an estimate of current rates, use the RenoIndex simulator to receive a price range in CHF.
Technical compatibility and installation
Before any purchase, it is imperative to check the compatibility of the battery with your existing inverter. If you already have a photovoltaic installation, some battery models may not be easily integrated.
A preliminary technical audit by a professional helps avoid unpleasant surprises and ensures optimal system efficiency. Installation in accordance with Swiss standards is crucial for the safety of your building in Davos.
To estimate these technical works and include installation costs, the RenoIndex simulator provides a clear estimate in the form of a price range in CHF.
Planning and budget in Davos
Budget planning is essential for any solar storage project. In addition to the cost of the battery itself, remember to include labor costs and any necessary upgrades to your electrical infrastructure.
In the canton of Grisons, it is recommended to request several quotes to compare offers. Keep in mind that the quality of the equipment influences the lifespan of your system.
To facilitate your planning, our RenoIndex estimator is at your disposal to provide you with a reliable price range in CHF, adapted to local specifics, with no obligation.

Frequently asked questions
Is a permit required for a battery?
Generally, installing a home battery indoors does not require a building permit. However, always check local regulations in Davos regarding fire safety for lithium energy storage systems. A compliant installation is essential.
What is the average lifespan of a battery?
Most lithium solar batteries offer a lifespan between 10 and 20 years, depending on the number of charge cycles and the quality of the device. Optimal temperature management extends this longevity.
Can I install the battery myself?
It is strongly advised against performing the installation yourself. The electrical connection requires certified skills to ensure safety and validate manufacturer warranties. Hire a qualified professional for your work.
How does the battery handle power outages?
Not all batteries provide automatic emergency power. If you wish for backup functionality during power outages, ensure that your model and inverter are specifically designed to offer a backup feature.
