The Plus-Energy House generates more energy than it uses

 

 

“Generating more energy than you use”; this is the concept of the Plus-Energy House. With our show home in Wuppertal we show how this concept works in practice. A photovoltaic system uses sunlight to generate electricity, which in turn is controlled by an energy management system.
On sunny days, when more electricity is produced than is needed, the intelligent home management system diverts unused energy into a central storage facility. When the evening electricity requirement is no longer covered by the photovoltaic system, the house draws on energy from the storage system. Only once this is empty does the house switch over and draw from the public electricity grid.

 

 

INTERESTING FACTS

 



  

 

A Plus-Energy House offers greater independence from energy price rises by using its own
free solar energy.



 

Reductions in feed-in tariffs for home-produced electricity makes using your own energy
increasingly attractive.



 

 

 

Smart control technologies ensure that priority is given to using the electricity
produced by the house itself.
This can be achieved, for example, by automatically activating appliances such as
washing machines, dishwashers or water heating as soon as sufficient energy is generated.


  

 

Surplus electricity can be stored, fed into the public grid for payment or used, for example,
to power electric vehicles.
