   FAQ-SolarFrequently Asked Questions: 
 
 
 - What is "Wp" or "kWp"
-  
- Variants of a solar system

- How long does a solar system last?
-  
- What does "surplus feed-in" mean?
-  The electricity generated from the photovoltaic system is first and foremost used in the house and stored if necessary. The remaining energy is fed into the public power grid. 
- What does "full feed" mean
-  In contrast to excess feed-in, in the case of full feed-in systems, all the energy generated by the photovoltaic system is fed into the public power grid. This only makes sense in exceptional cases, ask us. 
- How much electricity does a solar system produce
-  
- South orientation or east-west
-  
- Can solar panels be recycled?
-  
- What does "70% curtailment" mean?
