Technical FAQs 4

Where is energy stored in a photovoltaic system?

The energy from the photovoltaic system is stored by the power storage unit and consumed directly by electrical consumers, such as the heat pump. In the event of a surplus of energy, the energy is stored temporarily in the power storage unit battery and released again when required.

How does a photovoltaic storage system work?

So when it comes to photovoltaics with storage, the system usually involves an electrochemical storage unit such as a battery. The functional principle is quite simple. The PV battery storage system stores the electrical energy, similar to a rechargeable battery, until a demand arises in the household.

What is solar power storage?

Solar power storage offers the great benefit of being able to use self-generated electricity when it's needed. That means even when the sun is not shining. Electricity can be stored in two ways –– directly and indirectly. For domestic use, however, only indirect storage systems are an option.

How does a PV battery storage system work?

The PV battery storage system stores the electrical energy, similar to a rechargeable battery, until a demand arises in the household. It then passes that power on to the connected consumers (light, refrigerator, TV system, etc.). In detail, this means that when the sun's rays hit the photovoltaic modules, they are converted into direct current.
