Your benefits

  1. 01.return on investment
    From the first year after your installation, you'll notice a reduction in your annual electricity bill.
  2. 06.savings on my electricity bill
    As soon as you install your solar panels, you'll notice a reduction in your electricity bill.
  3. 02.accessible investment
    Today, photovoltaics is an affordable investment for all Belgian households. The price of panels has fallen sharply over time (divided by 6 in 10 years!). Today's banks are ready to finance photovoltaic projects thanks to their long-standing proven profitability.
  4. 07.concrete participation in the energy transition
    Given that the lifespan of an installation is between 25 and 30 years, that's as many years of carbon-free energy production. A real boost for the climate.
  5. 03.longevity and reliability of my system
    Thelifespan of an installation is between 25 and 30 years.
  6. 08.monitoring my live production
    Whether you opt for a SMA or SolarEdge inverter system, you benefit from a tool for controlling and monitoring your installation. An application allows you to view the production of your panels in real time.
  7. 04.possibility of adding a battery
    Today's inverters are compatible with future battery installations.
  8. 09.my property increases in value
    With a lifespan of +/- 25 years, photovoltaic installations generate substantial savings that you or future buyers of your property can benefit from.
  9. 05Improving my EPB
    Another point is that the photovoltaic installation has a direct impact on the property's PEB rating, and should therefore increase its value.

FAQ ?
  • What is self-consumption?
    Self-consumption is the amount of electricity generated by your panels that you consume directly.  
    • If your self-consumption is 0%, that means you don't consume the electricity your panels produce at all. Everything is redistributed on the network.
    • If your self-consumption is 100%, that means you consume all the electricity your panels produce.
    The greater your self-consumption, the lower your prosumer tax in Wallonia (if you have a smart meter). In Brussels and Flanders (from 01/01/21), you'll benefit from a higher increase in the price of your kWh. Indeed, the average purchase price of a kWh is 23 centimes, while the average resale price is closer to 5 centimes. Consuming electricity rather than feeding it back into the grid means you'll earn 4 times as much! A recent article has been written on this subject for maximum understanding:   https://soltis.be/news/comprendre-economies-panneaux-solaires-belgique-2023/  
  • How can we contribute to the energy transition?
    Years of carbon-free electricity generation.
      According to the International Energy Agency(IEA), it takes between 2 and 3 years for a solar panel to generate the energy required to produce it. This figure is constantly falling, thanks to the ongoing development of panel performance. Given that the lifespan of an installation is between 25 and 30 years, that's as many years of carbon-free energy production. A real boost for the climate!   What's more, as Greenpeace details in this article, "... panels are 95-99% recyclable for most manufacturers. Whether they were built in China or Europe..."

Your installation in 7 steps

  • 01
    REQUEST A QUOTE

    One of our experts will contact you to discuss the best solution for your needs and your home. At your request, we'll send you a detailed, no-obligation quotation for your future installation, free of charge.

  • 02
    YOU'VE MADE THE DECISION

    You're ready to produce your own electricity and invest in photovoltaics! You return the signed quotation to us. We prepare your administrative file and your project can begin.

  • 03
    TECHNICAL VALIDATION

    On payment of the first deposit (20%), we make an appointment with you to carry out a technical inspection. During this visit, all key points (roofing, electricity, building layout) are analyzed in detail to ensure optimal installation. Based on this information, we draw up the final layout diagram for your installation.

  • 04
    INSTALLATION

    It's D-Day! After agreeing a date with you, our technical team will install your photovoltaic system. The project takes 1-2 days to install, depending on the size of your system.

  • 05
    ELECTRICAL RECEPTION

    We commission and supervise the electrical acceptance of your installation by an approved inspection body (included in the quote). This is mandatory.

  • 06
    REGISTERING YOUR INSTALLATION

    Once the acceptance document is in our hands, we prepare the administrative file for registration of your installation with your GDR (each region has its own Network Manager).

  • 07
    YOUR SYSTEM IS UP AND RUNNING

    Now you can generate your own electricity!

Stage 04 in 5 points: from securing and preparing the site to electrical installation.

Your App

Keep control of your system at all times with your mobile monitoring application.

  • Track your production in real time
  • Get a global view of your production over the entire life of your plant
  • A production problem? Check your inverter's status information and detect if a problem exists

Your inverter is more than just an electronic component, it's the brain of your installation. It controls your photovoltaic panels in real time to produce maximum energy at all times. Thanks to your mobile app (delivered free of charge with your system), you can keep track of your system's production at all times.
