Battery systems
Use your own solar power even when the sun isn't shining
A battery system stores the electricity your solar panels produce for later use and helps increase your energy independence.
Battery systems
Use your own solar power even when the sun isn't shining
A battery system stores the electricity your solar panels produce for later use and helps increase your energy independence.
Solar power for later use
A battery complements a correctly sized panel system
Solar panels produce electricity when the sun is shining. A battery makes it possible to store part of that production for later use, so your own solar power can be put to better use even after it's generated.
Timing of production and consumption
Solar panels produce best during the day, but part of your consumption happens in the evening and at night.
Greater use of your own solar power
Surplus stored in the battery can be used later as part of the property's own consumption.
Compatible sizing of panels and battery
The battery's size is planned together with the solar panel system so the whole matches the property's needs.

Let's find the right panel-and-battery solution for your property
Tell us the basics about your property and its electricity consumption. We'll use them as the starting point for a suitable panel-and-battery whole.
- A free assessment doesn't commit you to a purchase.
- A solution matched to your property's needs
- A clear proposal for the scope of the panels and battery
- We usually get in touch the same business day
A working whole
What a working panel-and-battery system includes
A battery doesn't work as a standalone device — it's part of the same whole as the solar panels and inverter. The parts need to match each other and fit how the property is used.
Solar panel system
The foundation that produces electricity for the property's use and for storing in the battery.
Compatible inverter
Converts the electricity the panels produce into a form usable in the property and the battery.
Battery
Stores part of the solar panels' production for later use.
Control and monitoring
The system's operation can usually be tracked and controlled through its own interface.
The exact configuration and features vary by system and are reviewed as part of the assessment.
How the battery works as part of the system
How energy flows from production to use
A battery's operation is based on a simple principle: the surplus between production and consumption is directed into storage instead of straight to the grid.
Panels produce electricity
Solar panels produce electricity while the sun is shining.
The property uses the production
Part of the production is used directly in the property as it's generated.
Surplus is stored in the battery
Unused production can be directed into the battery within its capacity.
Stored energy is used later
Electricity stored in the battery can be used later, for example in the evening or at night.
How the solution proceeds
A clear path from initial information to commissioning
A panel-and-battery solution is designed from the property's starting information, whether it's a new system or complementing an existing solar panel system.
Starting information and current system
We review the property's electricity consumption and details of any existing solar panel system.
Designing the whole
We design a compatible sizing of the panels and battery based on the property's needs.
Proposal and compatibility check
You get a clear proposal, and we confirm the battery's compatibility with the property before you decide.
Installation
The agreed solution is installed according to plan and connected to the property's system.
Commissioning
The finished system is checked, commissioned and reviewed together with you.
One plan for the panels and battery, and a clear path from start to commissioning.
FAQ
Battery systems — frequently asked questions
Is a battery always worth it with solar panels?
Not always. A battery increases the use of your own electricity, but its value depends on your consumption profile and goals. In the assessment we determine whether a battery is worthwhile for your property.
How large a battery is needed?
Battery size is based on consumption, the size of the solar system and your goals. An oversized battery doesn't necessarily improve the economics.
Can a battery be added to an existing system?
Yes. You can start with solar panels and add a battery later. The design can account for a future battery, and compatibility with the existing system is checked in the assessment.
Does a battery work during a power outage?
Not automatically in every system. Backup power during an outage requires a compatible system and the right configuration. We'll determine the possibility in the assessment.
How does a battery affect the payback time?
A battery increases the investment but adds to the use of your own production. Payback depends on consumption and the electricity price, and is estimated per property.
Where is the battery located?
The battery's placement is planned according to the property's spaces and technical requirements as part of the assessment.
How can I monitor the battery's use?
The system's production and use can usually be monitored through its own app or interface. The exact features depend on the system chosen.
