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.

With 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.

Fields marked with are required.

Both figures are on your annual statement or in your energy supplier’s app. Do not know a figure? Leave it empty and we will ask.

We work it out by hand and email you the result.

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.

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.

  1. Request a quote first

    Brand and type have to be on it, otherwise the Warmtefonds cannot assess the application.

  2. 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.

  3. Have the battery fitted

    By a certified installer. That is also the condition for the warranty.
