Start With Shifting Use
Run the washing machine, dishwasher and charging moments during daylight. This costs nothing and already reduces feed-in — before a battery is considered.
A battery can help you use more of your own solar power, but it is not a guarantee of savings. The order matters: first shift consumption to the moments you already generate power, then look at a system, and finally read your own meter and contract data to see what actually changed. This guide explains that sequence, including the costs beyond the battery itself. No fixed returns are promised.

Your tariff structure — including feed-in and peak rates — together with quarterly meter readings shows where the money actually goes.
Purchase, installation, any subscription or service plan and possible monitoring fees belong in the comparison — otherwise a calculation flatters itself.
The savings calculator on the Dutch section gives an indication based on your input. Treat the outcome as a starting point for a conversation, not as a promised return — real results depend on your behaviour and tariffs.
Send your consumption, solar yield and tariff details. We review them, explain what a system can and cannot influence, and quote the scope — without fixed savings promises.
