How quickly does a home battery pay for itself?Have it calculated for your home.

With a home battery, you use more of your own solar energy and need to purchase less electricity from the grid. Request a personal calculation and discover how quickly a home battery can yield a return in your situation.

Calculate payback period

An investment that can pay for itself

Many investments in a home improve your comfort or increase the value of your property. A home battery can also be financially attractive. By using more of your own solar energy, you need to purchase less electricity from the grid. This can make a significant difference to your energy bill.

The most important question is therefore: how quickly does a home battery pay for itself? This depends on various factors, such as your solar panel installation, your energy consumption, and when you use energy.

That is why at iLumen we always provide a calculation tailored to your situation. This way, you discover how much extra solar energy you can use yourself and how quickly a home battery can yield a return for your home.

Calculate Your Payback Period

Why invest in a home battery?
The figures speak for themselves

For the calculation of the scenarios below, we use the following installation values: the PV system produces 4,000 kWh/year, the consumption is also 4,000 kWh/year, and a 4 kVA inverter is active. Additionally, we use a price of 330 euros / MWh for consumption and 40 euros / MWh for injection (VREG rates Q1 2024).

Solar panels with
reversing meter

€840

Annual savings

  • Energy production savings: 4 MWh/year x 330 €/MWh = €1,320/year
  • Prosumer rate: 4 kVA x 90 €/year = €360/year
  • Other taxes: ≈ €120/year
  • Net energy savings: €1,320/year – €360/year – €120/year = €840/year

Solar panels with
digital meter

€484.40

Annual savings

  • Self-consumption level 28% (i.e., 72% injection). Source: VREG
  • Injection: 2.88 MWh/year x 40 €/MWh = €115.2/year
  • Self-consumption: 1.12 MWh/year x 330 €/MWh = €369.6/year
  • Net energy savings = €484.8/year (loss of €355.2/year over 20 years)

Solar panels with digital meter
and iLumen technology

€980.10

Annual savings

  • Injection: 0.9 MWh/year x 40 €/MWh = €36/year
  • Self-consumption: 1.12 MWh/year x 330 €/MWh = €369.9/year
  • Battery storage: 1.98 MWh/year x 290 €/MWh = €574.2/year
  • Net energy savings = €980.1/year
TESTIMONIALS

What our customers say

Installation of an Ilusmart: installation went smoothly and quickly with the necessary explanation. They kept their appointment. Clear app to monitor injection and withdrawal. Satisfied!

Koen Van Brusselen

Everything nicely installed, my panels inspected and coated! ...and now just waiting to see if the newly installed PIDbox improves the efficiency of my panels.

Jos Martens

Perfect collaboration with experienced staff. Service as it should be.

Jos Janssens

Thanks to your site, I can see if my installation is returning to how it was at the beginning, or what percentage I recover by applying the PID-BOX principle.

Luc Cuvelier

After years of paying too much for energy, finally a system that works for me. The technicians knew exactly what they were doing and explained everything clearly. The app is highly recommended!

Fleur van den Broek

They responded quickly to my request, and the installation was arranged within a week. My panels are now running at full capacity thanks to the PIDbox. I should have done this sooner.

Sander Vermeer

Friendly technicians who really know what they are doing. Installation completed neatly, no mess left behind. Via the app, I can now see live how much I produce and inject. Great!

Noor Bakker

My old panels had been producing less than expected for years. After the coating and the PIDbox installation, I notice the difference immediately. The system now monitors itself — handy!

Joris Hoekstra

Professional from start to finish. Appointment kept punctually, installation went smoothly, and the Ilusmart app works intuitively. Finally, I have a grip on my own energy consumption.

Roos van Dijk

Good communication before, during, and after the installation. The technician took the time to show everything via the app. Small investment, but the difference in return is already visible after one month.

MEET ILUSMART

Manage your solar energy from your pocket

With the iLusmart app, you always have your entire solar installation at hand. You not only monitor your solar panels but also easily oversee connected devices such as your inverter or home battery. This increases your self-consumption and automatically saves on your energy costs.

In the app, you can see at a glance what your installation is doing. You track your consumption in real-time, compare it with previous months, and gain insight into how much energy you draw from the grid or inject. iLusmart also provides smart tips to help you save even more energy and shorten the payback period of all your devices.

FAQS

Frequently Asked Questions

Which combination of solutions works best?

That depends on your situation, but the greatest gains are achieved with a mix of generation (solar panels), storage (battery), and control (iLusmart).

Does it make sense to invest if I already have solar panels?

Certainly. Without a battery or control system, you inject a significant amount of free electricity back into the grid. With smart management and storage, you can utilize that energy optimally.

How much can I save with a home battery?

Up to hundreds of euros per year. You consume more of your own solar energy and draw less (expensive) electricity from the grid.

What is the fastest way to reduce my energy bill?

Start with solar panels. This allows you to generate your own energy and avoid expensive grid consumption. Combine this with a home battery for even greater impact.
