Renovations, heritage and volumes
For your renovation plans in Herisau, the official register indicates that three buildings are under heritage protection, requiring you to contact the municipality early to navigate permit requirements. Please note that data coverage for this figure is partial. Regarding building volume, the 1736 recorded houses lack measured data according to the SIA 416 standard, making it harder to estimate the scale of heating or insulation works based on these records alone. We strongly recommend consulting local experts to assess the specific technical requirements and dimensions of your property before finalizing your renovation budget and timeline.

Why install a solar battery
A battery is worthwhile when solar output clearly exceeds your daytime use. In Switzerland, the trend is to maximize self-consumption because the price of grid electricity is often higher than the feed-in tariff.
Storing your surplus allows you to use your own clean, free electricity during evening consumption peaks, ensuring better financial returns while strengthening your overall energy autonomy within your home in Herisau.
Sizing your storage system
Sizing is a critical step to avoid unnecessary costs. It is recommended to size the capacity based on your evening consumption, not the power of your solar panels. Analyze your energy habits over a full year to determine your real needs.
A battery that is too large represents a high initial investment that might never pay off, while a battery that is too small will not cover your needs enough. Find the right balance to optimize your investment using our RenoIndex tool.
Essential technical checks
Before buying your equipment, check compatibility with your existing inverter. Some modern systems are hybrid and can natively integrate a battery, but others will require an additional storage-specific inverter.
Also, ensure the chosen location for the battery complies with current safety standards. Ambient temperature and humidity play a crucial role in the lifespan and performance of lithium-ion cells.
An installation performed by a qualified professional will ensure the durability and safety of your system in Herisau.
Planning and budgeting
Budget planning is the final step before implementation. In addition to the cost of the battery itself, don't forget to include installation fees, potential electrical panel updates, and commissioning costs.
In Herisau, as elsewhere in the canton of Appenzell Ausserrhoden, prices can vary based on the complexity of the integration into your existing infrastructure. We advise you to use the RenoIndex estimator to anticipate these expenses.
Good planning ensures you stay on budget while maximizing the energy efficiency of your solar project.

Frequently asked questions
How much does a solar battery cost?
The cost varies depending on the capacity and the technology chosen. For a realistic price range based on current costs in the canton of Appenzell Ausserrhoden, we invite you to use our free RenoIndex estimator.
Do I need to replace my inverter?
It depends on your current installation. If you have a hybrid inverter, it can often accommodate a battery directly. Otherwise, an additional battery inverter might be necessary. Check for compatibility before any purchase.
What capacity should I choose for my home?
The ideal capacity should cover your typical nighttime consumption. Analyze your electricity bill and your habits to best size your battery and avoid unnecessary overcapacity.
Is a solar battery always profitable?
Profitability depends on your self-consumption rate. The more you consume the energy you produce yourself, the more interesting the battery becomes. It is especially useful for homes where consumption significantly exceeds daytime production.
