Renovations, heritage and volumes
For your renovation plans in Grabs, please note that the federal building register data is currently partial. With a median house volume of 776 m3 calculated from a sample of 30 buildings based on the SIA 416 standard, these figures provide a baseline for estimating the scale of your heating or insulation upgrades. As the register covers 2120 buildings, please be aware that information regarding renovation years is unavailable and no properties are recorded as protected heritage sites. Consequently, you should rely on professional on-site assessments for these specific aspects while using the volume data as a reference.

Why install a battery?
A battery is worthwhile when solar output clearly exceeds your daytime use. By storing the surplus, you avoid feeding all the energy back into the grid and maximize your domestic self-consumption during dark hours.
This reduces your reliance on external suppliers and allows you to use energy produced locally on your roof.
To assess the cost of such an investment and see potential savings, do not hesitate to consult RenoIndex to obtain a clear price range in Swiss francs.
Correct sizing of storage
Size capacity by evening consumption, not panel power. It is unnecessary to oversize a battery if your nighttime usage is low. The goal is to reach a balance between maximum storage capacity and hardware purchase costs.
A rigorous review of your consumption habits is necessary before selecting a specific model. To get a quantified estimate based on your home type, use our RenoIndex estimator, which provides a price range to guide you with confidence.
Compatibility and installation
Check compatibility with your existing inverter before buying. If your current system does not allow for battery retrofitting, an upgrade might be necessary, which will impact the total cost of the work.
Hire certified professionals for the installation to ensure safety and electrical compliance.
To anticipate expenses related to this technical installation, the RenoIndex simulator helps you visualize average market costs for your energy-related renovation works.
Planning your project
The planning of a storage system should be thought out for the long term. Consider the potential evolution of your consumption, such as purchasing an electric vehicle or installing a heat pump, which could increase your energy needs.
By grouping renovation projects together, you might optimize labor costs. Use RenoIndex to get a reliable cost estimate.
Our tool allows you to plan your energy renovation work in Grabs transparently, without obligation and with a clear view of the necessary budget.
