Photovoltaic system: Private customers

There are (at least) five good reasons why you should install a photovoltaic system: you can reduce your energy costs, you will not be affected by rising electricity tariffs, you can increase the value of your property, and you can benefit from subsidies along the way. But the best part is that by switching to a sustainable energy source, you will be making a crucial contribution to the energy transition. 

A photovoltaic system can be installed on any roof, slanted or flat, on new buildings or existing ones. Our experts will adapt the system to the architecture of your property. Modern technology has made it possible for a variety of solar panel configurations to be produced, such as on- or in-roof mounting and/or façade mounting. 

Have you ever thought about the fact that you could also use your solar power to produce hot water or charge your electric vehicle? If so, come and chat to us – we are here for you!



How solar panels work 


Solar panels are systems that convert solar energy into electricity or heat. The electricity is generated from renewable energy sources, which is why the process is particularly sustainable. Solar panels are made up of individual solar cells and can be installed on roofs, façades or open land.

Because these systems are increasingly commonplace, solar energy is becoming ever more efficient and affordable. There are two different types of solar panel systems: solar thermal installations and photovoltaic systems.


  • You can reduce your energy costs.
  • You will be less affected by changes in electricity prices.
  • You will increase the value of your property.
  • You will benefit from government subsidies.
  • You can make tax savings.
  • You can generate electricity without producing CO2 emissions.

Difference between photovoltaics and solar thermal energy

Both photovoltaic systems and solar thermal installations are classed as solar panel systems. In both cases, the sun is used as and converted into a source of energy. The fundamental difference:


  • Photovoltaic energy produces electricity
  • Solar thermal energy produces heat



Photovoltaic systems convert the solar energy generated into electricity, while solar thermal installations use solar energy to produce heat. This heat can be used to provide your property with hot water or heating.

Heat pump combined with a photovoltaic system

Would you like to boost the efficiency of your solar installation? If so, combine your photovoltaic system with a heat pump.

How will you benefit? By installing solar panels, you will produce the electricity your heat pump needs cheaply and sustainably on your own roof. And thanks to a buffer tank that stores hot water, you will have hot water and cosy heating 24/7, even at night when the sun is not shining.

When installing both pieces of technology at the same time, the solar panels can be directly integrated with the heat pump. If you already have a heat pump, almost all models can be adapted retroactively.



Generally speaking, heat pumps are suitable for both new builds and existing buildings. It is therefore possible to have a heat pump installed at any time.
