Why invest in solar storage?
A battery is worthwhile when solar output clearly exceeds your daytime use. By storing the surplus energy produced during sunny hours, you reduce your reliance on the grid.
This allows you to meet your energy needs during the evening and night, when solar panels are inactive.
Increased autonomy is a major asset for any homeowner looking to improve their property value while achieving long-term savings on household electricity bills. Investing in storage turns your existing installation into a more efficient power source.
Sizing and technical compatibility
Size capacity by evening consumption, not panel power. Over-sizing your battery leads to unnecessary costs, while under-sizing limits your potential savings. Furthermore, always check compatibility with your existing inverter before buying any hardware.
Some systems are designed to work exclusively with specific hybrid inverters.
Consulting a qualified professional allows you to tailor the storage capacity to your household's actual habits, ensuring a durable and efficient setup that works seamlessly with your current energy infrastructure.
Regulatory and administrative framework
While there are no specific municipal grants mentioned for Lenzburg, it is advisable to check cantonal programs periodically.
Ensure that your certified installer carries out the necessary declarations to guarantee that your solar installations and battery meet national technical standards and operate safely.
Getting a budget estimate
The cost of a solar battery depends on the technology and the storage capacity required for your household. To avoid unpleasant surprises, use the RenoIndex simulator for free to get a price range adapted to your project.
This estimate allows you to compare installer offers with a clear view of the market. Remember to include professional installation costs, as proper mounting is key to the longevity of your storage system and the safety of your home.

Frequently asked questions
What is the lifespan of a solar battery?
Most modern lithium batteries installed in Switzerland have a lifespan of between 10 and 15 years. This figure strongly depends on the number of charge cycles and the temperature management within your utility room.
Can I install a battery if I already have panels?
Yes, it is entirely possible to add a battery to an existing solar installation. However, it is mandatory to verify the technical compatibility with your current inverter or to consider adding a dedicated hybrid inverter.
Where should the battery be installed?
It is best to install the battery in a dry, temperate, and well-ventilated room, such as a basement. Extreme temperatures can significantly reduce performance and longevity. Avoid areas that are prone to moisture.
Does the battery work during a power outage?
This depends on your equipment. Some batteries are designed to provide backup power, but this function must be specifically planned and installed by a professional during the configuration of your home energy system.
