A home battery lets you use more of your own solar power and rely less on the grid. You save on feed-in costs and keep power available when you need it.
A home battery stores power generated during the day for use later. Useful if you use a lot in the evening or want to avoid feed-in charges.
Lower feed-in costs: Use your own power instead of feeding it back at low rates.
Power when you need it: Power is available in the evening and during outages.
We look at your usage, solar setup and fuse box to choose a battery that fits.
During the day your panels often generate more than you use. Instead of feeding that surplus back, you charge the battery with it. Once the sun is gone, you use the stored power for your lights, cooking or the TV.
The battery talks to your inverter and fuse box. A smart system charges when you generate and discharges when you use power, with nothing for you to do.
The less net metering gives you, the more attractive it becomes to keep your own power. A battery pays off most if you use a lot in the evening, have a heat pump or EV charger, or want to be more self-sufficient.
Whether it adds up financially depends on your use, the size of your battery and your energy tariff. We are happy to run the numbers with you, at home or at our office in Amstelveen.
Capacity, in kilowatt-hours, says how much power the battery holds. Power, in kilowatts, says how fast it can charge and discharge. A battery that is too small runs empty quickly in the evening. One that is too big never fills. The right size depends on your use.
With a dynamic energy contract you charge the battery when the electricity price is low, often midday or overnight, and use it when the price spikes during the evening peak. That creates an extra way to save, completely separate from your solar panels.
The power grid is filling up in more and more neighbourhoods, especially during the evening peak. A home battery relieves the grid twice: it absorbs your solar surplus at midday and delivers that power to your home in the evening, exactly when demand peaks.
In designated congestion areas there is something in return: grid operators pay a grid congestion payment through energy suppliers for batteries that take part during peaks. We install steerable brands as standard, so your battery can join such a scheme, now or later.

Thuisbatterij laten installeren: Het eerste contact met Marco is positief. Hij reageert telkens vliegensvlug op al mijn vragen, ook in de avond en het weekend, dus Marco: dat mag wel iets minder! De installatie verliep niet vlekkeloos, maar wel naar tevredenheid. De monteur is supernetjes en vriendelijk en gaat door tot het netjes klaar en afgerond is. De prijs is concurrerend. Prima partij die mij betrouwbaar overkomt.

Begin dit jaar zonnepanelen aangeschaft via Solarfast, werden zeer vriendelijk te woord gestaan en correct geholpen. Een mooie prijs overeengekomen.

Uitstekende ervaring met zowel Electricien als de Panelenplaatser! Vakkundig, vriendelijk, meedenkend, afspraken nakomend en de kwaliteit van aansluiten én afwerking is gewoon heel goed!

Good contact with Raymond, quickly agreed on the price of a Hyxipower 10kWh battery, which was then delivered quickly and neatly installed by Team Ali. So far so good. The battery works well after a lot of searching in the app, but that is not Solar Fast's fault.

On April 22, 4 solar panels were installed at our location by 2 employees from SolarFast. The work started exactly on time and was carried out neatly and quickly. Afterwards, a good explanation was provided at an installed site to monitor
