What we connect

Five disciplines, one crew that masters all of them. Below, per service: what we do, up to which ratings, and what you are handed at completion.

Net metering ends 1 January 2027

Your surplus will be worth half. Unless you store it.

From 2027 the Dutch net-metering scheme ends; during the transition a statutory minimum feed-in tariff of 50 % of the bare supply rate applies. At the same time the grid is filling up. Storage moves your midday surplus to the evening peak — and keeps your connection out of congestion.

Open price indication

We break the price apart before you have to ask.

“Contact us for a price” is not an answer. This is what a typical home battery costs with us, line by line — including what is not in it.

This example is hypothetical. What you actually pay depends on the job itself — what is already there, what has to be replaced, how the cable runs — and on the travel distance to your site. A binding figure follows the intake, in writing.
