Renovations, heritage and volumes
For homeowners planning renovations in Würenlos, the RegBL data provides critical context. Regarding heritage protection, 264 out of 1367 known buildings are officially protected, necessitating early contact with the municipality to clarify permit requirements. Data coverage remains partial in other areas: information on the renovation year is unavailable for all 1479 buildings. Furthermore, the volume of 1094 houses is documented without reference to the SIA 416 standard. Consequently, assessing the scale of insulation or heating works is less straightforward, and homeowners should consult technical experts to determine accurate requirements given the absence of median volume figures.

When is a battery profitable?
A storage battery becomes a wise investment if your solar production clearly exceeds your daytime consumption. The main goal is to maximize the energy you produce yourself instead of re-injecting it into the grid at a low price.
Before starting, analyze your annual and daily consumption profile. If you consume most of your electricity while the sun is shining, the utility of a battery will be limited.
Conversely, for a family present mainly in the evening, storage provides a financial advantage and immediate energy security.
Choosing the right storage capacity
It is a common mistake to size your battery based solely on the peak power of the solar panels. In reality, sizing should be based on your evening consumption.
A battery that is too large represents an unnecessary cost that will extend the payback period of your installation. A battery that is too small will not cover your night-time needs.
Ideally, aim for a capacity that covers your typical energy needs between sunset and the following morning, while leaving a safety margin for less sunny days.
Technical compatibility and installation
Before any purchase, it is imperative to check technical compatibility with your existing inverter. Depending on whether your system is DC or AC coupled, the requirements for battery integration differ.
Some installations allow direct coupling, while others require an additional hybrid inverter. Hiring a certified professional is highly recommended to ensure a secure installation that complies with standards in the canton of Aargau.
A professional can also advise you on the optimal location for the battery, ideally in a dry, temperate place to preserve cell lifespan.
Financial aspects and estimation
The cost of a storage system varies depending on the technology used, such as lithium-ion, and the chosen capacity.
Although there is no specific municipal grant in Würenlos, it is important to consider the savings made on your electricity bills over 15 to 20 years. To better understand your investment, use our RenoIndex estimator.

Frequently asked questions
Do I need a permit to install a battery?
Generally, a home battery located indoors does not require a building permit. However, ensure that the electrical installation complies with Swiss safety standards. We advise you to consult your installer or local energy office to confirm if any specific requirements apply to your particular building in Würenlos.
What is the average lifespan of a solar battery?
Most modern solar batteries, especially those using lithium-iron-phosphate technology, have a lifespan of 10 to 15 years or more. Longevity depends heavily on the number of charge and discharge cycles, as well as the environmental conditions where the battery is stored.
Can I install the battery myself?
No, installing a solar battery involves complex electrical work and must be carried out by a qualified professional. A correct installation is essential not only for the hardware warranty, but especially for your fire safety and compliance with current Swiss standards.
What grants are available in Würenlos?
Currently, there are no specific municipal grants in Würenlos for the purchase of storage batteries. However, it is always wise to check incentive programs from the canton of Aargau or occasional offers from your local electricity provider that might encourage energy self-consumption.
