Buying home battery in Rotterdam

Do you generate more power with solar panels than you are currently using? Then much of that energy flows directly into the electricity grid. With a home battery, you store this generated power for later use. This way, you use your own energy when you need it and are less dependent on energy suppliers and fluctuating electricity prices.

That importance increases further in the coming years. From 1 January 2027, the net-metering scheme will end completely. Supplied solar power will no longer be offset against your own consumption, but paid out at a lower rate. This makes it increasingly attractive to use self-generated energy directly or store it cleverly.

Rotterdam is a dynamic city with a wide variety of housing: from high-rise buildings and city flats to spacious single-family houses in new housing estates. At the same time, the electricity grid is under pressure in many parts of the city, while solar panels are increasingly being installed. Shift to Solar helps homeowners in Rotterdam choose and install a home battery that suits their home, energy use and future plans. Not a standard solution, but a system that logically fits your situation.

Calculate the right capacity for your home battery immediately

The capacity of a home battery determines how much electricity you can store for later use. A well-chosen battery will ensure that you use as much of your own solar power as possible, without investing in unnecessary capacity or falling short at key times.

Which capacity suits you depends on several factors. Consider the number of solar panels, your annual energy consumption and especially how you use power spread throughout the day. In Rotterdam, we often see that generation is high during the day, while consumption peaks mainly in the evening. That makes a well-tuned battery extra valuable.

Our calculation tool gives you a quick first indication of which battery capacity might make sense for your home. This result is intended as a guideline, not final advice.

If you request a no-obligation quote from Shift to Solar, we will look beyond just this calculation. We analyse your consumption, generation, peak moments and any future plans, such as electric driving or expansion of solar panels. Based on this, we recommend a home battery that is technically sound and remains pleasant to use on a daily basis.

Why a home battery in Rotterdam is becoming increasingly interesting

The way we use electricity is changing rapidly. Solar panels provide more and more local generation, while the electricity grid in big cities like Rotterdam is not always up to the task. At the same time, the rules around feed-in are changing. That makes it more important to take control of your own energy.

Solar panels and grid load

On sunny days, solar panels often produce more power than you are currently using in your home. This excess energy is fed back into the electricity grid. In Rotterdam, that grid is reaching its maximum capacity in more and more places, especially during times when many households feed in at the same time.

Grid operators need to keep the grid stable and reliable and cannot absorb unlimited power. As a result, feed-in is under pressure and fees are becoming less and less attractive. The financial benefit of feed-in is therefore becoming more uncertain.

With a home battery, you use this power yourself. You store the energy during the day and use it later, e.g. in the evening or early morning. This way, you get more output from your own solar panels and become less dependent on the electricity grid, without having to change your lifestyle.

Abolition of the net-metering scheme

Besides the increasing pressure on the electricity grid, legislation is also changing. From 1 January 2027, the net-metering scheme will end completely. Returned solar power can then no longer be settled at the full electricity tariff, but will be paid out at a lower rate.

This greatly affects the efficiency of solar panels. Not feed-in, but smart own consumption becomes decisive. A home battery makes this possible by storing excess solar power and using it at times when it benefits you most.

What is a home battery and how does it work in practice?

A home battery is a system that allows you to store electricity for later use. The battery captures the power your solar panels generate, but which you do not need right away at that moment. Instead of delivering this energy back to the grid, you store it in your own home.

The goal is clear: use as much of your own generated power as possible, even when the sun is not shining.

This is how it works in practice

During the day, solar panels often generate more power than you consume directly. Appliances are off, occupants are not at home and consumption is low. Without a home battery, this excess energy is automatically fed back into the grid. With a home battery, the power is stored first.

When you need electricity later in the day, for example in the evening or at night, you use this stored energy. Only when the battery runs out will the system automatically switch to power from the grid.

In practice, the proportion of own power consumption can increase from an average of about 30% to 60% or more, depending on your situation.

Home battery combined with solar panels

A home battery works together with your solar panels and the inverter. The inverter converts the generated solar energy into usable power for your home. Smart control ensures that charging and discharging happens automatically. You don't have to do anything for this yourself.

Through an app or monitoring system, you have insight into your energy production, storage and consumption. So you can see exactly how much of your own power you are using and when the grid is tapped.

Which home battery suits your home?

Choosing the right home battery goes beyond just the number of kilowatt hours. Of course, capacity plays a role, but how and when you use power is also decisive. Think about peak times in the evening, charging an electric car or plans for a heat pump.

The examples below give a first impression based on situations we often encounter in practice. They help with orientation. The exact capacity always depends on your home, consumption and plans.

Small household

• Solar panels: 6-8 panels
• Annual consumption: ± 3,000 kWh
• Indicative battery: 3-5 kWh

Average family

• Solar panels: 8-12 panels
• Annual consumption: ± 4,500 kWh
• Indicative battery: 5-10 kWh

Large household

• Solar panels: 12-16 panels
• Annual consumption: ± 6,500 kWh
• Indicative battery: 10-15 kWh

With electric car or heat pump

• Solar panels: 14+ panels
• Annual consumption: 7,000+ kWh
• Indicative battery: 10-20 kWh

Common mistakes when choosing a home battery

When choosing a home battery, we regularly see a number of mistakes in practice. By taking these into account beforehand, you avoid the battery not being a good fit for your situation later on.

• Choosing a battery that is structurally too large or too small, resulting in inefficient use of storage capacity
• Looking only at the purchase price, without considering use, efficiency and lifespan
• No allowance for future additions, such as a charging station, heat pump or additional solar panels

By looking closely at your energy profile and plans beforehand, the home battery remains a logical choice even in the long run.

What does a home battery cost?

The cost of a home battery varies from one situation to another. Every home, installation and way of using energy is different. Factors such as the desired capacity, the technical situation in the house and any future plans play an important role.

That is why we do not work with fixed prices. At Shift to Solar, you always receive a customised, no-obligation quote. This gives you a clear and complete overview of the investment in advance, with no surprises afterwards.

Subsidies and schemes for home batteries

Subsidies and schemes sometimes come into play when buying a home battery. At the same time, it is important to be realistic about this. The possibilities vary from situation to situation and change regularly.

National schemes and VAT benefits

National schemes for home batteries are limited. In some cases, VAT refunds are possible, for example when combined with solar panels and under specific conditions. This varies per home and installation.

We always explain clearly which regulations apply in your situation and what you can and cannot expect.

Provincial and local opportunities

In addition to national schemes, there may be provincial or local initiatives. These are often temporary and not available for every property.

Together, we look at what is applicable in Rotterdam and give a realistic picture of the possibilities.
