One of the most frequently asked questions about home batteries is also the most difficult: what is the payback period? Logical, because a home battery is a significant investment. But a simple answer does not exist. The payback period depends on your energy consumption, your solar panels, energy prices and the changes coming to the energy market. Nevertheless, good estimates can certainly be made.

In the video below, advisor Diederik and CFO Wilfred delve deeper into the financial side of a home battery, the impact of the net metering regulation and the expected payback period.

Why is the payback period difficult to determine?

Unlike solar panels, the return on a home battery strongly depends on how you use energy. The main factors are:

• The amount of electricity you consume annually
• The number of solar panels you have
• The size of the battery
• Whether you have an electric car
• Energy prices
• The compensation you receive for electricity fed back to the grid
• Any feed-in costs from your energy supplier

As a result, the payback period can vary considerably per household.

What is the payback period of a home battery in 2026?

For an average household with solar panels, an electric car and a home battery that is well matched to consumption, the payback period currently often lies between five and eight years. This remains an indication. The final outcome depends on the assumptions you make about energy prices and future developments. According to Wilfred, CFO of Zonnefabriek, it is wise to be conservative in this calculation: "A payback period of five to eight years is quite achievable for me at the moment, depending on the situation."

How is the payback period calculated?

When determining the payback period, we don't just look at the purchase price of the battery. We first analyze:

• How much solar power you generate
• How much of it you use directly
• How much you feed back to the grid
• How much electricity a battery can additionally store for you

We then calculate how much additional solar power you can use yourself instead of feeding it back. Other benefits then come into play, such as:

• Saving on electricity purchase during expensive hours
• Smart charging when electricity is cheap
• Less impact from feed-in costs
• More independence from price fluctuations

Together, these factors determine how quickly the investment is recouped.

What happens to the payback period when the net metering regulation ends?

This is where it becomes interesting. As long as you can net meter, solar electricity fed back generates approximately as much as electricity you consume. As a result, the financial added value of storage is limited. After the disappearance of the net metering regulation, this changes. It then becomes much more attractive to use generated solar power yourself. A home battery helps with this by storing excess solar energy during the day and using it later. This directly impacts the business case.

Can a home battery soon be paid back within a shorter time?

For some households, yes. When the net metering regulation disappears and electricity fed back becomes less valuable, the value of self-consumption increases considerably. As a result, the calculations can turn out much more favorable than today. This especially applies to households that:

• Generate a lot of solar power
• Consume relatively much electricity
• Have an electric car
• Have their battery controlled intelligently

As a result, a home battery becomes financially interesting for more and more households.

Is waiting advisable?

That depends on your situation. On the one hand, the financial added value of a home battery may increase in the coming years. On the other hand, we see that demand is growing and delivery times may increase. Those who expect to want to install a home battery in the future would therefore do well to inform themselves in time.

The conclusion: the payback period is becoming increasingly attractive

Where a home battery was mainly a technical innovation a few years ago, the financial justification is becoming increasingly stronger. With the disappearance of the net metering regulation, the payback period for many households can become considerably shorter. The exact payback period remains dependent on your situation, but one thing is clear: the financial benefits of energy storage are becoming increasingly greater.
