Renovations, heritage and volumes
For homeowners planning renovations in Romanshorn, official RegBL figures provide vital context. Data coverage regarding building volume is partial, with seven houses measured under the SIA 416 standard showing a median volume of 830 m3, which helps gauge the scale of necessary heating or insulation work. Regarding heritage protection, out of 2023 registered buildings, 278 are known, with zero recorded as protected. We recommend contacting the municipality early in your planning process to confirm your property's specific status, as this ensures all local permit requirements are fully addressed before you begin any construction projects.

Evaluating battery profitability
A solar battery is particularly worthwhile when your solar output clearly exceeds your daytime use. By storing the surplus, you can power your home in the evening or early morning when generation is low or non-existent.
Before committing, analyze your annual consumption profile to determine long-term profitability.
Use our RenoIndex estimator to get a realistic price range for your project, allowing you to weigh the initial investment costs against the potential savings on your yearly electricity bills and make an informed decision for your home.
Optimal sizing
The common mistake is sizing the battery based on panel power. It is much better to size the capacity according to your evening and night consumption. A battery that is too large incurs unnecessary costs, while one that is too small limits your savings.
Observe your daily habits to determine your actual needs. Our RenoIndex tool helps you calculate a relevant budget range based on the desired capacity. Careful planning is essential to ensure a better return on investment for your storage system.
Compatibility and technical setup
Before buying, it is imperative to check compatibility with your existing inverter. If your inverter is not designed for storage expansion, you might need to replace it or add an energy management device.
An installation complying with Swiss standards ensures the safety and longevity of your hardware. Consult specialized installers to evaluate the technical constraints of your home.
Then, use RenoIndex to obtain an estimate of total costs, including necessary components and labor, to avoid any financial surprises during the implementation.
Maintenance and lifespan
Modern batteries are low-maintenance, but periodic performance monitoring is recommended. Regularly check the Battery Management System (BMS) to ensure it is functioning correctly.
The lifespan depends significantly on the number of charge cycles and the ambient temperature. When planning your investment, remember to factor in potential future replacement costs.
For a clear view of initial costs, RenoIndex provides a comprehensive price range, allowing you to plan your renovation budget calmly over the long term. A well-maintained system maximizes your home autonomy.

Frequently asked questions
What is the typical lifespan of a solar battery?
Most lithium-ion batteries for residential storage have a lifespan of between 10 and 15 years. This primarily depends on the number of charge cycles and the specific operating conditions.
Do I need a permit to install a battery?
Generally, installing a battery inside an existing building does not require a building permit, but it must strictly comply with current Swiss electrical safety standards.
Can I install the battery myself?
No, the installation must be carried out by a qualified electrician to ensure compliance with Swiss standards and guarantee your safety as well as the safety of your electrical system.
How can I estimate the cost of a battery?
Use our RenoIndex tool to obtain an adapted price range. Costs vary depending on the capacity in kWh, the chosen technology, and the complexity of the necessary installation work.
