Let us work it out for you. The advice is free.
On 1 January 2027 Dutch net metering ends: feeding back then earns far less than electricity costs. What you store and use in the evening, you no longer have to buy.
Three figures decide which set-up is right
Too small and you have nothing left in the evening, too large and part of the capacity sits idle. That is why we start from the figures of your home.
Figure 1
What you take from and feed back into the grid
The basis of the whole sum: how much electricity you take from the grid and how much you feed back. Not to hand? Then we estimate it from your household.

Figure 2
Your solar panels
The number of panels and watt-peak per panel decide when there is a surplus to store. No panels? Then we will not ask about them.

Your connection
Single-phase means the FlexVolt One LV, three-phase the HV. Do not know? We work it out together.
readable in the meter cupboardWith these details we work out your advice
The more you fill in, the sooner your advice is ready. Not sure about something? Leave it empty or choose “I am not sure”: we get in touch and complete it together.
Where to find the figures
Consumption and feed-in are on your annual statement or in your supplier’s app. The watt peak is on the quote for your panels or on the rating plate. You can read your connection in the meter cupboard.
Stuck? Call or email us and we will go through the figures together.
We use your details only to make this calculation and send you the advice. You can read more about that in our privacy policy.
No number rolls out of a machine
Someone looks at your situation, and you hear from us as soon as the advice is ready.
We work it out by hand
We set your consumption against your generation and your connection. If something does not add up, we call first.
You get the advice by email
If you want to go ahead, we put you in touch with a certified installer in the Netherlands.

- Version and size
- LV or HV, and how many kWh
- What each size returns
- solar power per year from the battery
- Your savings
- per year, with payback period
- Indication of the costs
- with VAT refund under conditions
- Your own consumption
- monthly profile with meter data
- Use and next steps
- practical advice and what comes next
Financing
Rather spread it? The Warmtefonds lends along
With the Energiebespaarlening from the Nationaal Warmtefonds you pay for the battery in instalments. It starts with the quote, not with the loan.
-
Request a quote first
Brand and type have to be on it, otherwise the Warmtefonds cannot assess the application.
-
Submit the application to the Warmtefonds
Send the quote along. Conditions: you are owner and occupant, it is for private use and the battery is on your own property.
-
Have the battery fitted
By a certified installer. That is also the condition for the warranty.
