Generate your own
sustainable power
With solar panels you use the power of the sun every day for the energy you need at home.
The sun does not always shine when you need power. With a home battery you save today's energy for your cup of coffee tomorrow morning. Or use it on cloudy days and in the evening.

The most from your solar panels
Smarter use of
the energy you generate
The sun does not always shine when you need power. With a smart home battery you save today's energy for your cup of coffee tomorrow morning. Or you use stored energy on cloudy days and in the evening. That way you use more of your own power and depend less on the grid.
A home battery is especially interesting if you now feed a lot of your own power back to the grid. By storing that energy from your solar panels and using it yourself, you pay no feed-in charges on that power. And by using more of it yourself, you lower your energy bill. With a dynamic energy contract, a smart home battery can buy when prices are low and feed the rest back at the most favourable moment.
Using your solar panels smarter and smarter
On 1 January 2027 the net metering scheme ends. What you feed back can then no longer be offset against what you take from the grid. You get a feed-in payment for it, which until 2030 is at least 50 percent of the bare supply rate. Power you use yourself is power you do not buy. That is why it becomes smart to use more of your own generation yourself. With a home battery you store the power you do not need during the day for the evening. How much that is worth depends on your usage, your contract and your feed-in payment.

Well-considered advice
Consider your future electricity use
It is wise to choose a system that fits your situation and your plans for the future. During an advice call we therefore look not only at your current use, but also at what you can expect in the coming years. For example whether you will drive electric or are considering air conditioning or a heat pump. Great, of course, if you can generate that energy yourself.
A smart system grows with you. If you use and want to store more power in the future, modules for extra capacity can often be added. We are happy to explain everything, so you can make the right choice with confidence. And your system grows with you when your situation changes and that is needed.
An extra attractive investment
Can I reclaim the VAT?
Investing in a home battery can be extra attractive, because you can sometimes reclaim the VAT on your home battery. Answer a few questions and find out right away whether you qualify for a VAT refund on your home battery.

Question 1 of 7 - location
Where will your home battery be installed
You can reclaim VAT if you buy and sell power with the battery: with an energy management system (EMS), a dynamic energy contract and an energy supplier that pays you for the power you feed back. You then become an entrepreneur for VAT purposes. The invoice and the energy contract are in your name, and when you buy the battery you do not take part in the small business scheme (KOR). If you only use the battery privately, you cannot reclaim the VAT. All conditions are explained under home battery VAT refund.
With a smart home battery you store the energy you generatebut do not use straight away for a later moment.And that way you get even more out of your home battery.
Own use
By using as much stored power as possible yourself, you hardly have to feed anything back to the grid. That is why we look at exactly what suits you.
Ideal capacity
With a battery that is too small you still buy power from the grid. And with one that is too large you still feed power back. That is a waste, so we think along with you on what suits you.
Dynamic rates
Power prices change all the time. With a dynamic energy contract, a home battery can buy when power is cheap. And feed the rest back at the most favourable moment.
Backup power
A smart home battery can supply backup power during an outage. Good to know that your most important appliances simply keep working. You will not even notice.
No noise nuisance
You can barely hear a home battery. The only sound comes from the cooling fans and the inverter, which switch on while charging and discharging. It is comparable to the sound of a fridge.
Installed within a day
Worry-free installation from start to clean-up
Before installation we check that everything is ready for a safe placement. We then install the equipment neatly to all regulations and make sure everything works perfectly. We show you how the system works and answer your questions on the spot. When we are done we leave everything tidy. That way everything is sorted within one day and you start saving right away.
Our installers make sure your home battery is fitted professionally and neatly. It is no coincidence that our customers rate us a 9.4 on average. Like more and more people in the Netherlands, choose smart home energy from Solar Fast.
Your solar panels and home battery
open up many more options
Easily extend your system with extra capacity, an EV charger, a heat pump or air conditioning.
And with a dynamic energy contract, a home battery can buy when power is cheap.
EV charger
With your own charger you simply charge your car at home. Your charger and home battery work together smartly. Plan your own charging sessions and charge automatically at the cheapest moments. And when there is a power surplus, charging is sometimes even free.
Heat pump
A heat pump takes heat from the outside air, the ground or groundwater to heat your home and tap water. With a hybrid heat pump you use less gas. And with an all-electric heat pump you no longer need gas at all.
Air conditioning
A modern air conditioner can not only cool, but also heat. Heat is then drawn from the outside air and blown into your home. They can even ventilate and stop dust and pollen with advanced filters.
Maybe you have been thinking about solar panels, a home battery or a heat pump for a while, but you are not sure where to start. Understandable, because smart energy can seem more complicated than it is. Luckily, it really is not. In a few steps we show how we make smart energy at home easy.
Our approachAdvice that fits your situation
We simply sit down with you at the kitchen table. That is where it starts. We look at your home, your energy use and what matters to you. And how you can keep benefiting from smart power once the net-metering scheme ends. Quick insight and honest advice, so you know exactly where you stand.
The Dutch power grid is full in some places
A new or larger connection is then not always available right away. We call that grid congestion. If you also choose a home battery, the grid carries less load. Nice!
More and more green energy, and less emissions
If we store all the power we generate ourselves and shift it smartly, the Netherlands makes the best use of the green energy available. We then need fewer and fewer fossil fuels.
A good choice for your energy bill and your home's value
With solar panels and a home battery, it is not just your energy bill that goes down. They raise the value of your home, partly through a better energy label. A smart investment for later.

Frequently asked questions
That depends on your situation. From 1 January 2027 you get a payment for the power you feed back instead of net metering. Every kilowatt hour you use yourself instead of feeding back is one you do not have to buy. A battery helps with that, especially if you generate a lot during the day and use most of it in the evening. Whether it pays off financially depends on your usage, your energy contract, your feed-in payment and the price of the system. See also with or without a home battery.
By using as much stored power as possible yourself, you hardly have to feed anything back to the grid. Power prices change all the time. With a dynamic energy contract, a home battery can buy when power is cheap and feed the rest back at the most favourable moment. That lowers your energy bill straight away.
No, you do not have to do anything. Your smart home battery is controlled automatically and kept up to date by an Energy Management System (EMS) or smart software. Your battery decides for itself when to charge most favourably, buy cheap power from the grid or supply power to your home.
Your home battery keeps the power you generate but do not use straight away until you need it. The capacity depends on the size of the battery. On average, a battery can supply a household with normal use for a whole day. And with more economical use as backup power during an outage, even longer.
A home battery can certainly be suitable for backup power, but that is often not standard. A normal home battery switches itself off for safety as soon as the power fails. For power during an outage you need a home battery with an Emergency Power Supply or a backup box or inverter. Good to know: the Dutch grid is getting fuller, but it is still reliable.
Even more savings
Smart energy at home gives you more grip on your energy costs. And even better: a smart home battery can help you not only save, but also earn extra by supporting the grid.
