A home battery is cost-effective. Fact or fable?

FACT!

The market for home batteries is growing. In fact, since 2024, the home battery is VAT-free if it has smart software and is linked to a dynamic energy tariff. A home battery leads to less dependence on the energy grid. This is obviously hugely beneficial in these turbulent times! But did you know that they also offer attractive financial returns? A home battery is profitable and we would be happy to tell you more about that!

What is a home battery?

Is it wise to buy a home battery and what is it? A home battery, or home battery, stores the energy generated by your solar panels. This means that you can use the power generated whenever you need it, even when the sun is not shining. So this means you can make money, so to speak, with a home battery. As you use more of your own generated power, you consume less power from the grid. This makes for great savings on your power costs. So buying a home battery is definitely a smart investment because you can store the solar power generated by yourself and use it whenever you want.

The benefits of a home battery:

• You take full advantage of price fluctuations: buy low, sell high.
• You use more of your own generated power from solar panels, therefore you lean less on the grid.
• A home battery is cost-effective in that you will recoup the investment within about 5 years: saving on energy costs.
• A home battery is cost-effective for a more sustainable future. In fact, you reduce your carbon footprint by being less dependent on the power grid.

Is a home battery cost-effective?

Imagine that your solar panels produce more energy during the day than you use. With a home battery, you can store this excess energy and use it later, such as in the evening or on cloudy days. This makes you less dependent on the electricity grid. A dynamic energy contract with home battery also allows you to respond optimally to fluctuating energy rates. When rates are high, you can feed the stored energy back to the grid and make money with it. This is how you become a mini energy supplier! Smart, right?

When is a home battery cost-effective?

A home battery is profitable when there is a dynamic energy contract. This allows you to purchase energy during off-peak times, when rates are low. You can then use this stored energy during peak times, when prices are higher. With solar panels, a home battery is even more attractive. In fact, this combination allows you to use up to 60% of your own generated energy. Furthermore, the profitability of a home battery depends on a number of factors:

1. Home battery price: average cost between €4,000 and €10,000, depending on brand, type and capacity. Prices are expected to fall in the future, improving profitability.
2. Home battery capacity: the capacity must be matched to your solar panel installation. You won’t get the most out of a battery that is too small; a battery that is too large will provide less efficiency.
3. Home battery efficiency: lithium-ion batteries have an efficiency of about 95%. Lower quality batteries can have an efficiency of only 70%, which means loss of energy.
4. Home battery life: the average life is 14-15 years, with a maximum life of up to 20 years. A longer lifespan means more time to recoup your investment.
5. Presence of solar panels: with solar panels you can increase the use of your own energy from 30% to 70%.
6. Salaring scheme: currently you can still fully net up until 2027. After the abolition of the balancing scheme, a home battery will become more attractive, because you will be less dependent on supplying back to the grid.
7. Subsidies: there are currently no subsidies for home batteries, but future schemes may improve profitability

Financial benefits

Dynamic energy rates allow your battery to take full advantage of price differences. A home battery can thus save you hundreds of dollars annually. Although the initial investment for a battery is quite high now, you will recoup this amount within a few years. With long warranties, you can be sure they will last a long time.

Sustainable future

With a home battery, you become less dependent on energy suppliers and fluctuating energy prices. You also contribute to a more sustainable environment by using your own solar energy and delivering excess energy back to the grid. This makes the home battery not only a financially smart choice, but also an investment for a sustainable future.

Research shows that only 30% of self-generated energy is consumed directly, with the remaining 70% flowing back into the grid. With a home battery, this self-consumption can be greatly increased to as much as 65%. In short, storing your own energy is a powerful way to become (more) self-sufficient!

A home battery is definitely a profitable revenue model. It not only offers financial savings, but also increases your energy independence and contributes to a greener future. Do you want to take maximum advantage of your own solar energy while lowering your energy bills? Then investing in a home battery is a smart choice.
