Renovations, heritage and volumes

For your renovation projects in Solothurn, the federal building register (RegBL) indicates that 3 buildings are listed under heritage protection, requiring early coordination with the municipality for permit applications. The building volume data covers 1517 houses with a median volume of 462 m3 according to the SIA 416 standard, which is essential for scaling your heating and insulation upgrades. Please note that data coverage is partial, as 1514 buildings are recorded under unknown or other standards. Since renovation year data is not available, you should conduct a thorough on-site assessment to accurately plan your specific property improvements.

Why install a solar battery

A battery is worthwhile when solar output clearly exceeds your daytime use. By storing the surplus, you avoid feeding all your energy back into the grid and can use it in the evening. This reduces your reliance on standard electricity suppliers.

However, before proceeding, analyze your load profile. If your production is low during the winter months, the battery will not be fully charged. The investment must be based on a thoughtful self-consumption strategy to be truly profitable in the long run.

Proper sizing

Sizing is the crucial step of your project. Contrary to common belief, you must size the capacity based on your evening consumption, not the power of your solar panels.

A battery that is too large represents an unnecessary cost, while one that is too small limits your autonomy. Accurately assess your nighttime needs to choose the most suitable storage capacity in kilowatt-hours (kWh).

Use the RenoIndex tool to estimate the costs associated with different storage capacities and make the right choice for your home in Solothurn.

Technical compatibility

Before any purchase, systematically check compatibility with your existing inverter. AC and DC coupling systems work differently.

AC coupling is often easier for retrofitting an existing solar system, while DC coupling is preferred for new photovoltaic installations combined with storage.

Ensure your current equipment can communicate with the new battery for intelligent energy management. A compatibility error can lead to additional installation costs or a loss of efficiency in the overall system of your home in Solothurn.

Renovation project in Solothurn

Carrying out energy renovation work in Solothurn requires rigorous planning. Beyond the choice of hardware, you must take into account the installation conditions in your home.

Good ventilation and a stable ambient temperature are necessary to ensure the lifespan of the battery cells. Do not hesitate to request several quotes from qualified installers in the region to compare services.

Use the RenoIndex estimator to define your budget and get an overview of market prices. Thorough preparation is the key to a successful and sustainable energy transition for your property.

Frequently asked questions

What is the lifespan of a solar battery?

Most current lithium batteries have a lifespan of between 10 and 20 years. This longevity strongly depends on the number of charge cycles and the temperature management in your technical room.

Does a battery mean I no longer pay for electricity?

No, it mainly helps to reduce your bill by increasing self-consumption. In winter, solar production is often insufficient to cover all your needs, so you remain dependent on the grid during sunless periods.

Where should I install the battery in my house?

It is best to install it in a dry, clean room with a stable temperature, such as an insulated basement or a ventilated utility room. Avoid areas exposed to major temperature variations or humidity.

How can I get the price for the work?
