Renovations, heritage and volumes
For your renovation projects in St. Gallen, the RegBL data provides essential guidance. With 122 protected heritage buildings out of 147 known, contacting the municipality early is vital for securing building permits. Data regarding house volume is partial, covering only 3 buildings measured under the SIA 416 standard with a median of 805 m3; this metric helps scale your insulation or heating works. Please note that the renovation year is not recorded for any of the 8987 buildings listed in this register, meaning this specific information is currently unavailable for your strategic planning.

Why install a battery?
A battery is worthwhile when solar output clearly exceeds your daytime use. By storing the surplus, you avoid exporting excess energy to the grid at potentially low rates.
This allows you to use the electricity produced for free by your panels during peak evening consumption. It is a strategic choice to maximize self-consumption, especially in a canton like St. Gallen where sunlight varies by season.
Remember to consult the RenoIndex simulator to understand the locally relevant price ranges for your installation.
Sizing your capacity
It is essential to size the storage capacity based on your evening consumption, not just the power of your panels. A system that is too large is an unnecessary investment, while a system that is too small will fail to cover your nightly needs.
Analyze your household consumption profile to determine the ideal battery size. RenoIndex offers a free calculation tool that considers these variables to provide you with a price range adapted to your situation within the canton of St. Gallen.
Prior technical checks
Before buying, you must check compatibility with your existing inverter. Some inverters are designed to work specifically with certain battery brands, while others require additional hardware.
A poorly configured installation could lead to efficiency losses or unforeseen extra costs. Also, ensure the location chosen for the battery offers a stable temperature and adequate ventilation to ensure its longevity.
For seamless planning, use the RenoIndex simulator to get a reliable price range for your work in St. Gallen.
Regulations and advice
Beyond the technical aspect, think about evaluating the future evolution of your energy needs, such as buying an electric vehicle or installing a heat pump. These devices could significantly change your demand.
